Hi every one just thought i would share my story,
i was looking at putting a super charger on the magna, now that sprintex dont make kits
there was not much to look at i went to look at Raptor but there kit is not ready yet.
So i thought i would like some thing that was custom any way, just cost more but that way you have a one off.
Any way i went to Bullet Super Cars had a chat with them, a week later i dropped my car off, we decide to put a Rotrex Super charger on it because they have not fitted one to a magna yet there is no kit all custom built.
So far Custom Rotrex Super charger system Fitted
Custom Water to Air intercooler
Costom Cold Air induction K&N pod
will tell more when i have a full list of things done to the car,
its now on its way to Chip Torque for the next week.

nice :D

looks tuff as, cant wait to see the end!

looking good.....
got a rough figure yet $$$$

very noice :)

needs a strut brace across the top, more bling :D

:stoopid:, frak me nice work, good stuff

Sweeeeeet... that should moove along nicely.:badgrin:

They'll soon have a kit for the magna then.:badgrin:

Thanks guys i am happy with the way it has turned out so far
not sure what it will cost till the job is done
but i think it will be over $ 10,000 because of the custom work done on it

thats a fat supercharger, one of the bigger ones they have

any chance of seeing where exactly you have mounted it?!

They'll soon have a kit for the magna then.:badgrin:


I would think so now they have made it once they will have kept all the templates

Very nice!
I'm very jealous. :D

Fact & figures when know would be great.
eg.
- Time to install (time the car was off the road)
- Cost of project (when finished)
- Was it all done by a mechanic or did you do some (helps others when considering the cost)
- Dyno figures B4 & after.
- What parts were off-the-shelf, what parts had to be custom made, etc.
- lucky finds, problems encountered, lessons learned.
- and, anything else you wish to tell us.


or keep any/all of the above a secret - up to you. :D

Where the heck is your alternator now?

Oh - I see, would be pretty interesting beltwork now...

Where the heck is your alternator now?
who needs electrics!

Far out nice work! That looks very tidy and professional!

What computer are you using?

Congrats for being adventurous!!! :thumbsup:

When the job is done i will get Bullet to list every thing for me i will post up in more detail
and i will post up the dyno chart

Bling BLING!!!

Good to see someone putting their money where their mouth is for a change.

I enquired with these guys a couple of months ago, I was quoted $6500 + installation. Looks good, I love the belt-driven turbo type blower, and intercooling is nice for peace of mind and consistency. Will be very interesting to see how the numbers stack up to the sprintex kit.

congratulations mate, its great to see someone doing something adventurous!!! Let us know how it works out.

looks neat, love the fabrication work, shiny.

Mate that looks mint, i hope you get some awsome figures when you are finished. atleast now we are starting to get a range of products for the magnas, thus a bit of competition between the companies.

mike

this will probably make more power than the sprintex as it can be easily intercooled. It looks very well done. These centrifugal types can also crank out up to 15psi can't they?

Slightly different principles - this style of blower will behave more like a big turbo with boost varying in proportion to revs. The screw type s/c have pretty much the same boost across the rev range.

I hope you have a piston upgrade planned, if not the blower will probably plan it for you anyway lol.

wow mate that looks the goods. once this is done and the raproe charger is done will be good to compare all 3 chargers togather.

that big shiny box iss the water cooler ye? very neat

If anyone gave you any negative feedback tell them to shove it! How could you NOT give some credit to you and the installers....
****en looks SICK!!

Nice job mate!

It`s gonna be interesting to see how much of a difference intercooling will make with a supercharger on the magna`s,it should make higher and more consistent power and torque,better throttle response,better fuel consumtion and could go a little more aggresive on the tune due to lower air temps

please correct me if im wrong

Looks very nice mate. What boost?? and what are you gonna use to tune it?? Have you planned for fuelling system upgrades?? or are you gonna see how far you can push the factory gear?? (I was planning on doing this, but then wimped out and upgraded everything at the last minute).

Also good to see another reputable Qld workshop tackling the magna forced induction puzzle.

BTW, manual or auto?

Wow!!

That looks awesome, good to see someone breaking the typical sprintex route everyone seems to take :shifty:

Definatly post more pics, dyno graphs and mod list when complete

Also try and get a video of this thing in action ;)

Bling BLING!!!

Good to see someone putting their money where their mouth is for a change.

+1

hope we see some decent power out of this, 200s minimum.

Pretty neat little setup there! :)

wow that looks unreal! good for you!

the only negitive thing i can see out of that setup is the maf sensor is right before the throttle body. I could be completly wrong and hopefully i am but i read up on the kits the yanks were putting on their mitsu eclipse's and they had issues with pushing the air through the sensor rather than have it sucked through which it is designed to do.
If you run out of fuel with the standard injectors which im sure you will, a cheap and easy fix is get 440cc injectors out of a toyota 7M-GTE engine and make up bigger dowels to sit your rail up off the intake manifold. a whalbro fuel pump will do the job as well.

besides that, looks unreal love the water to air intercooler box, and nice to see someone just do it and not dribble on for months and months with thier hopes and dreams

Good luck

Looks awesome

That looks like some nice work there. Interested to see what she does when she's all finished :cool:

Gorgeous workmanship. Much tastier to look at than the Sprintex setup

What boost is that running because it has one large pulley on it atm.
Nice work btw.

What boost is that running because it has one large pulley on it atm.
Nice work btw.

The larger the pulley at the SC end, the lower the boost. Being that his car is fairly stock appart from the blower, I'd say he'd be running lowish boost (7-8psi).

it's work of art, looks great, hope to see it finish and at super sunday at parklands on the 17th feb

i really like the setup they've gone with, they only thing that i'm a bit unsure of is the intake pipe running right along the exhaust.

personally i would have the front header remade to run further away from the charger itself and a heat shield made up for the pipe (if one is made already i can't see it in the pics)

but nice setup. looking forward to hear of results.

sorry dude but that 7th injector has dodgy written all over it. With the twin screw charger on the sprintex kit, the fuel is added about 50mm away from the screw, so the fuel atomizes (spell?) and has a pretty decent chance of being spread evenly. in your case, the fuel is added after the charge so the chances of it sitting on the walls of the plenium is increased and possibly depriving the fuel needed to the cylinders. For a couple of hundred bucks i'd get some decent size injectors installed.

the last picture just shows how good the setup is, i love the intercooler!

Thanks for your input, I agree it might need bigger injectors,and fuel pump,I was told that Chip Torque will take care of all that for me.All i know is i am more than happy with the job done on it so far,And if Chip Torque do as good a job finishing it off, I will be over the moon.

ChipTorque are a great company mate. Youll be please with the results im sure!


Kudos for jumping in the deep end and rolling with it!

The larger the pulley at the SC end, the lower the boost. Being that his car is fairly stock appart from the blower, I'd say he'd be running lowish boost (7-8psi).

I knew that, hense me asking and wondering what sort of boost it was running. Will 7-8 psi provide that much more power? Like im guessing 30kw or there abouts on top of supporting mods.

yes it will

my awd had 6.47psi at its peak and made 175kwatw up from approx 100-105kw atw stock

yes it will

my awd had 6.47psi at its peak and made 175kwatw up from approx 100-105kw atw stock


My VRX started at 6psi and ended up at 8psi and made 207hp at the wheels at approx 5800rpm in 4th gear at all dyno tuning (my tuner) with the air/fuel ratio in the low 11's. N/A my car made 185.5hp at Redcliffe Dyno. 400m time's went from 14.4 N/A to 13.5 Supercharged with a slipping clutch. MPH were 94-95mph N/A to 104-105mph Supercharged.

in conclusion, boost rocks!

i must say good choice in going chip torque. I'll be going the XEDE once i get my modified fuel rail and water/meth kit in as i have been told by quite a few people that its the closest piggyback unit u can get to a full stand alone system

I knew that, hense me asking and wondering what sort of boost it was running. Will 7-8 psi provide that much more power? Like im guessing 30kw or there abouts on top of supporting mods.

7psi is about half an atmosphere of positive pressure, so in theory you could expect to make approximately 50% extra power in a perfect world. Probably more like 35% extra power in reality though.

The Car came back from Chip Torque,it ran a little shy on fuel,The 7th injector was a 440cc it now will be changed to a 630cc, then it will head back to Chip Torque to finish the tune.Just to let you guys know the car made:
3.5L 6G74 SOHC 24V V6
AUTO 4 speed
Boost 8 psi
Made 176.2 KW ATW 240 Hp with the 440cc injector
These figures may change when it returns to C.T.with the bigger injector

nice really good job mate wish i could afford that hehe

your injectors are all maxxed out. just throwing on a bigger single injector is not the answer and a recipe for disaster! take it from me, i blew my engine up a week after i upped the boost and extra fuel was added by a bigger 7th injector. After i blew it up and i went back to the tuner, they said it was weak pistons and nothing to do with their tune or setup . . . BULLSH*T!

now i have modified my spare fuel rail for 440cc injectors, the only way to provide fuel properly. I really dont want to see you back here in a week/month/woteva saying you've blown your engine, no1 wants to see that!

Manual conversion, and you'll hit 200fwkw!

Yep. Do it properly or there will be tears. The 7th injector idea has already cost a few people on here a set of new pistons. Fuel distribution is a worry.

You will probably find that the two runners closest to the injector will be grabbing all of the fuel. Which means the other 4 are running progressivly leaner - very bad.

Take this advice seriously from another member of the busted piston club.

Honestly, you must not rely on a 7th injector to take care of your fuelling. You are right at the limits of your fueling if you are getting that type of wheel power figure through an auto box (I'd say you're making roughly 250kw at the flywheel).

Nice result, take care.




Talk to tzaboy for the toyota injector option.

You will probably find that the two runners closest to the injector will be grabbing all of the fuel. Which means the other 4 are running progressivly leaner - very bad.
we're lucky with the sprintex kit that the fuel gets smashed by the s/c so it is distributed pretty evenly, where as in john's case it isn't.

also another dangerous thing about the 7th injector in your setup, is when they dyno it they will tune it to get say 11.0 AFR (example) but you cant tell if all the pistons are running at that AFR because of the inconsistancy of where the fuel is being delivered.

I'll have picks of my fuel rail up over the wknd to show what ive done

Thats a good result from an auto mate, and I picked up about 36kW from a manual conversion if I remember correctly. So that means that you could be making about 200kW at the wheels thru a manual and at 8psi - that says to me that your blower is quite abit more efficient than the sprintex blower.

Just get your fuel issues out, as others have said - would hate to see you have piston meltdown because of poor fuelling after all the work that has obviously gone into it.

Solid results... as others said get those fuel issues sorted, I'd be paranoid to give it any stick running such a dodgy setup.

Also pretty criminal if you don't do a manual conversion.

btw congrats OP you should be really happy

got a real tyre fryer now lol

keep us posted!

now plans for convertor/valve body modifications?

dont be conned into a manual conversion if you dont want to

look up youtube there is a diamante that runs 12.14 1/4's with just a normal 4spd auto with uprated valve body!


also cant believe no one has asked ;)

post up the dynograph when you can thanks :D

Has anybody checked this site out? Not sure how they're gonna tune anyones car:bowrofl: :nuts:
Should be www.protekautomotive.com.au
Will most likely get my Verada retuned there since both andrewd and micjaiy had their 3rd Gens done there and both seemed happy with it

So your going then?


yeah sure as soon as the mods see these posts i assume were both going...



What a trippy thread...

Anyways, its bout time someone used one of these type of superchargers on a Magna! That thing is massive :shock:

ey john thats some great figures you have there. would be awesome to see the results when all is running 100%

So what mods did you have to get 134kwatw with? I cant even manage that with cams emanage zorst etc on a 2wd..must of had a uncalibrated dyno eh:nuts: good effort john

I think he had 100 odd kw before the Sprintex kit was put on, 134kw after the install, then went to 175kw after it was tuned up properly.

because this car is intercooled is probably why he'll hit the 200kw atw's mark with is awesome! if it wasnt it would rob him 50hp/35kw bringing it back to 165kw(ish). with the sprintex kit if u added a water/meth kit which i am you'll gain that 50hp/35kw

and the 2nd best thing is the fact that at 2000rpm its not on peak boost.... so when he wants to go nuts and run a 16psi pulley on it, it wont be putting 16spi into the engine every time its under load, unlike the sprintex kit..... high boost at really low rpm is going to be one real quick way to kill the auto box.... so at the end of the day this has the potential to match the output (almost) of the turbo engines if the rest of the gear can keep up with it...

should be one real nice ride...

any pics of the completed job?

:thumbsup: nice work mate looks good

i like very much good job



:zap:

What are you doing ECU wise? I see you have kept the MAF.

John Boy, any new pics or updates on your beast??? cant wait to see some numbers out of it and a sound clip to compare the sound of the 2 different chargers


Just got back from begin up the coast for the week end, I have to ring Bullet tomorrow
to see if the car is done,If all is good i will pick it up.
I will take a few pics of the finished job,and will get a full list of what was done to the
car and get my dyno sheet,I will post every thing up and break down the cost of the stuff used on the car, i will try to make a clip of the car running,once i do that ,do i down load it to you tube? and then will that give me a link to the clip?
Saw your fuel rail you made up very nice,i will look in to do doing the same sort of set up,
cheers.

First and last warning to anyone posting in this thread.

Phwoar...Now that is nice.

Great to see you followed an idea through to the end.
I want more pics that set-up is neat and tidy.

Gonna take out on the track or the strip anytime?
Be good to see some times.

mine was half on topic, but

can you ask them if they have the brackets ready to sell off the self

Looks hawttt.

Would love to see some quarter mile times eventually :)

Thanks, i have no plans to change the gear box, i want to keep the auto in it.
But down the track i might do some engine work so i can run more boost,
and trick the auto out,i will get the convertor done and shift kit,

cheers.

mine was half on topic, but

When i go pick the car up i will ask them about the brackets for ya,
Was planned to pick the car up today,But the new injector did not show up
yesterday,looks like they will get the injector today around lunch time,So with any luck i will get down there tomorrow.

did a bit of digging on this... it was actually +19kw atw

auto + mods (http://aussiemagna.com/forums/showthread.php?t=28440) = 122kw atw

manual + mods (http://aussiemagna.com/forums/showthread.php?t=30330) = 141kw atw

which is about a 16% improvement, meaning an auto with ~170kw atw (i.e. mine) *should* make about 195kw atw in manual guise...

which means these blowers offer about the same as the Sprintex kit, all things considered.

gotta get that money saved for the conversion!!!

cheers,

Memorys getting bad in my old age, sorry 'bout that. So yeah - 195kW, more like what a few others with manuals have gotten out of the sprintex kits.

tidy amount of power from an auto there.

"now i have to go for a Cruz" :D



So does that mean the cars gonna be making an appearance at Super Sunday then?

That absolutely craps on the power of a sprintex!
Woahhh

GEEEEEEE that is sweet out of an auto!!

And a very nice power curve!!! That would be sweet for everyday driving and awesome fun when poked!!

Congrats on getting out there and trying something new!

ahhh thats kool mate, well done, im sure that put a smile on ur face.

mike

man what were u thinking using an auto vehicle for this project???

get a manual box in there asap... and make sure you chuck an LSD in there while your at it.. god no's your gunna need it

WOW congrats dude. so what does it sound like???

This has been great reading through, well done on getting a charged cruiser!

Im sure there is a smile on your face knowing that the juice was worth the squeeze...

I want one too! :doubt:

Anyone got a spare jato rocket or three? :nuts:

why did chiptorque do the dyno run in 2nd gear? All that's going to do is give a missleading result (higher). Dyno runs are done in the gear closest to 1:1 and that's 3rd gear in 4-speed auto magnas.

:stoopid:

mind you I doubt it'll account for 10% (the difference between this car's power and mine), but it might be close. that and the intercooler would probably make the difference.

nice numbers though. what's it sound like?

As long as there isn't wheelspin, I don't see how lower gearing would change the reading.

Power = torque x rpm.

On a dyno this means power is calculated via tractive effort vs road speed, varying the gearing should not change the end power reading, only displayed tractive effort.

On a dyno this means power is calculated via tractive effort vs road speed, varying the gearing should not change the end power reading, only displayed tractive effort.

there must be a reason, as every dyno I've ever witnessed was done in the gear closest to 1:1.

hmm, research is needed.

.wook

EDIT: research completed:

At anything other than a direct 1:1 ratio in the transmission, the engine torque (power) is being multiplied, and an acceleration dyno has no way of ascertaining the transmission gear ratios of the vehicle being tested.

so there you have it... 1:1 is the most accurate way to determine torque (and power).

That power curve is absolute porn! Must be great to drive!

i think the reason dyno power runs are done in as close as 1:1 gear ratio as possible is its a more accurate display of engine performance; the rate at which it can increase crank speed.

ultimately it doesnt really matter what gear its done in, as long as when you are comparing future dyno runs for power upgrades and performance differnces, that you use the same gear each time, and if possible the same dyno as well.

so there you have it... 1:1 is the most accurate way to determine torque (and power).

I don't agree with what you quoted. As already said, power is measure by tractive effort vs roller speed. If you run 2:1 you are doubling the tractive effort but halving the roller speed, makes no difference to accuracy of power reading.

However I believe dyno operators like to use a close to 1:1 as possible, simply so they can use the same scales for the graph. If you change the gearing dramatically the scale needs to be changed. Also if you use too short a gear on the dyno you'll get wheelspin, which obviously doesn't provide an accurate reading.


i think the reason dyno power runs are done in as close as 1:1 gear ratio as possible is its a more accurate display of engine performance; the rate at which it can increase crank speed.


Bollucks, gearing has no bearing on accuracy (unless wheelspinning). Also "the rate at which it can increase crank speed" is not how a dyno measures power.

looks like some mad magna mod right there!

Going in 2nd gear isn't all bad, torque will read a lot higher but KW will still come out the same.

Good to see the progress, where did the dyno chart go to?

Sound's good a cross between a super charger and a turbo.
will post up a short clip soon.

how's the drivability?

Good, it feels great to drive went up the coast on Sunday.

Sounds pretty similar to the sprintex SC actually. Less belt noise though :rant:

Sounds awesome!! :D

here is a short clip of what the magna sounds like.



Interesting sounds.

Can you do one underload.. Revving while not moving doesnt really give an overall picture of what it would sound like while driving.


My car sounds totally different revving it while not moving compared to in motion :)

definatly need an in car foot to the floor run, or even get your mate to stand on the side of the road as you do a fly-by

Going in 2nd gear isn't all bad, torque will read a lot higher but KW will still come out the same.

Good to see the progress, where did the dyno chart go to?

all the reading I've done about chassis dyno's says that they only measure torque. you calculate the power (kw's) from the torque measurement, so if the torque is skewed by gearing, the power reading is going to be off as well.

cheers
.wook

sounds evil.

credible power figure imo

just make sure you keep that intake temp cool and squirt in some more fuel.

this is turning out to be a really good alternative to the top mounted screw type s/c.

can't wait to see one in an awd

Holy **** mate, what were you doing? Close to Mach 3?

all the reading I've done about chassis dyno's says that they only measure torque. you calculate the power (kw's) from the torque measurement, so if the torque is skewed by gearing, the power reading is going to be off as well.

cheers
.wook

From what I have been told/read I'm fairly sure dynos measure roller speed, to determine how to multiply the measured tractive effort (wheel torque) to get the correct power figure.

It makes no sense to assume 1:1 gearing in calculating power from tractive effort, as plenty of cars don't have a gear that falls very close to 1:1. Dynos obviously measure roller speed to plot speed on the graph, so it makes absolutely no sense that they would not use roller speed to work out what multiplier to use on tractive effort to calculate power.

But I'm happy to admit I'm not absolutely 100% on this. out of interest, if I get a chance I'll see If i can clarify this once and for all.

I'm fairly new when it comes to blowers, what are the cons and pros of a belt-driven-turbo style blower vs the sprintex (twin screw?).


This might help - from autospeed

http://blog.autospeed.com/2008/01/29/power-and-torque/

That doesn't clarify how dynos work, but gives a nice concise explanation of the relationship between between power and torque and what they are :thumbsup:

In a nutshell power = torque x time.

Torque being the rotional force produced, and time being revs at the crank or wheel/roller speed, depending on what where you are measuring.

Also note it is power that ultimately determines how fast you go. You can gear a peaky motor for more wheel torque, but not the other way round for a "torquey" but power-lacking motor.

In a nutshell power = torque x time.

MUCH better to say:

power = torque X rpm

I'm fairly new when it comes to blowers, what are the cons and pros of a belt-driven-turbo style blower vs the sprintex (twin screw?).


the twin screw is a positive displacement unit that delivers the same level of boost across a wide range of revs. the result is much more torque earlier in the rev range, but a loss of efficiency at higher revs.

the centrifugal type is more like a turbo, except mechanically driven. its boost is proportional to the rpm. it will suffer some lag at lower revs but continually builds boost with increasing rpm, with better performance at high rpm.

from what I have seen with the centrifugal unit, it is far easier to plumb in an intercooler compared to the top mounted sprintex unit. all other things being equal the centrifugal unit should be able to make more power.

the challenge is to get better response at low rpm from the centrifugal unit, a larger blower or faster drive speed is needed, but then the boost will continue to increase and by the time the redline comes up, it may be feeding in more than the stock engine can handle (well over 1 bar).

the sprintex can be increased to 10 psi by fitting a smaller drive pulley, but the inability to easily fit an intercooler makes this quite a delicate exercise.

the challenge is to get better response at low rpm from the centrifugal unit, a larger blower or faster drive speed is needed, but then the boost will continue to increase and by the time the redline comes up, it may be feeding in more than the stock engine can handle (well over 1 bar).

I was having a good look at a mates centrifugal setup on his 5.0L VS Commodore, he wanted a bit more response in the lower rev range but had the problem of over boosting at high rpm. He ended changing the compressor to a dual scroll type, this produced usable boost a bit lower in the revs, but ultimately made the upper rpm boost a bigger problem.

He ended up fitting an adjustable blow off valve (normal type used on turbo car) and set it to vent till just after it reached the max boost that was wanted (in this case 12psi). In addition the ECU is programmed to cut fuel if manifold pressure exceeds 14psi, in effect killing boost by reducing engine revs.

I think this new installation has a bov?

I wouldn't like to be anywhere near a 6G74 at 14psi on stock internals!

it might be alright if you could manage to feed it enough fuel.

:badgrin:

:badgrin:

A cooled charge with enough fuel, and maybe some head cleaning with special interest taken in eliminating any hot spots in the combustion chambers, I don't see why not. :cool:

I wonder if Bullet Cars have any dealers in Melbourne to do this conversion..... :D

A quick look over the compressor maps of the vortech units on the CAPA website will show you what rpm and boost to expect. I fully agree with oversizing the compressor for several reasons:

1) Increased efficiency
2) Can give bottom end more boost
3) If you upgrade your internals later, you don't have to buy a different compressor

An electronic boost controller that bleeds off excess is the best way to do this along with a fuel cutout.

Get max boost on as early as possible and bleed of the excess and you will have a motor that pulls and pulls and pulls...

Not using an EBC is insane given the potential of forcefeeding the engine. All these poor mans supercharger kits that only *just* meet the motorist's boost demands and peak out are a waste of people's hard-earned cash.

Even with the twin-screw chargers, select a charger with larger displacement and a water to air intercooler. Have your cake and eat it. However the ease of fitment and tuning of centrifugal systems make them the superior choice for nearly all aftermarket applications. OEM don't use them because people will quickly spec up centrifugal cars and Jaguar, Mercedes etc don't want that stigma around their names. They fall into the abovementioned boost at low rpm trap.

its an auto....

Awesome. I was down the coast last week with john boy and take it from me, this car is awesome. Loved every minute of it. Very quick and the sound gave me goose bumps all night:badgrin: . Sound like a cross between a supercharger and a turbo (guessing thats because of the oversized compressor). Real head-turner though. Nice neat job too. I am soooo jealous!:rant:

Thats a lot of money for a 180fwkw result.. :confused:
Though I commend your effort with this project.

A nice cam will give another 30-50kw comfortably without increasing boost. I plead with you to get the correct size 6 injectors and move away from the dreaded 7th fueller of piston death as a matter of urgency. Once done a quick retune will gain some more power and economy.

Great work mate, look forward to some more pics, clips and quarter mile work. :thumbsup:

Mr GVR4WA, 2 can play at your game! I've spent near 20 on my magna's engine for somewhere in the 200-250kw atw's area. Have yourself another dig.

GVR4WA,

Why don't you open a new thread and post your car up? You should list all the mods you have done and how much you have spent along with power figures.

Actually regardless of what car he drives, his point is valid as much as many of us (myself included) hate to admit it. The truth is you can pick up the early LS1 equipped holdens for the same price as a manual Ralliart or optioned up TL VR(X) magna nowdays and early XR6T's for only a couple of grand more. Drop $20K on either of those engines and you're looking at 500+kW at the wheels. And don't even get me started on the performance potential of countless different makes and models of imports in the same price range as late model magnas.

You can argue as much as you like that it's all about being unique, and not driving "XYZ" like every other wanker on the road, but at the end of the day, $ for $, kW for kW - magnas are **** to mod for performance.

yeah but we do it because we want to, and we dont need gronks coming on here and ripping up members. After all, 9 times out of 10 they dont own a magna!

I agree Mike, though I don't think it's as bad for our cars as people often assume.

Buy a skyline and you can make 200rwkw with a bunch of bolt-ons much cheaper than a magna.

But if you wanto make much more power you're looking at a rebuild with forgies, new turbo, new injectors pump etc. Once you get to this stage I'd argue bang-for-buck our motors are just as good as most, if not better than some due to having 3.5L of capabity which means good driveability with lots of power.

E.g there's no reason why you can't get forgies, get your rods shotpeaned with ARP rod bolts, get bigger injectors, bigger turbo(s) and make MUCH more power than you are currently. Along the lines of what Dave's RPW TT makes.

Then again knowing you, somehow it'll cost double the amount it should and take 6 months:bowrofl:

Also in the modding game its obvious there is alot of bull**** around, alot of people grossly exagerate gains and underestimate modding costs.

After all, 9 times out of 10 they dont own a magna!

Can't argue with that logic :cool:

It's gonna be like that then is it??? huh! Well okay...... show me a supercharged magna making more power than my car, and I'll show you a car thats had a full engine rebuild. 2x gearbox rebuilds is cheaper than 1 engine rebuild, and there's no guarantee that the blokes running blowers aren't gonna smash gearboxes either. So I don't think I've done too bad in the grand scheme of things.

Anyway - I'm not gonna **** fight about whose got the best magna and how much they've spent on it, I'm done with my car. It'll remain as is until it ****s itself again then I'll try to sell it and move onto something else.

its not about making a million horsepower, or trying to get more than X or Y car, its about enjoying our cars and modding them to what we want.

Well said. Everyone here already knows it's not as easy to mod Magnas as some other cars, but in the end they still choose to do so, pointing out the obvious is no help to anyone, especially when it demeans their thread in witch they just wish to share they pride and joy.

20 grand will get 400kw+ out of a 6G74 without changing the conrods or crank. Try that with a skyline engine and see how long it takes to chuck a rod.

The problem is finding something to transmit that power to the ground, that's where it gets a bit tricky.

There are heaps of 500kw falcons and commodores, how many with stock drivelines and if so for how long?

I highly doubt that 20K put into a magna will fetch 400KW thats pushing it dude, but regardless you are right magnas are very reliable and seem to handle extra power quite easily on stock internals but 400KW at the fly would be testing those internals to the max and could most likely say they would have blown around the 350kw mark even earlier!

The simple fact is magnas look good in our opinions anyways and they are original to modify and getting as much power out of these family cars is where the buzz is at imo so end of the day who cares what ppl say about modified magnas aslong as we enjoy it thats all that matters.

Booya spent at least $20K on the engine didn't he and got just over 300kw?

Mike you know I'm just joking with you:P

My point is with what you've done so far, it's been pretty poor bang-for-buck. Making about the same power as what a gtst skyline would with exhaust, intercooler and retune.

But if you were to take the next step of rebuilding and winding up the boost, there's potential for buttloads of power, at similar cost to what would be required to get a RB25DET to the same power level. And then you could argue you have better driveabilty.

You've had more than your share of bad luck, but unfortaunntely that's the risk you take playing the modding game, skyline/wrx/v8/whatever owners break stuff as well, so you havn't done so badly in that aspect.

I know 2x 350kw falcons for sale on their 3rd gearbox each. One is on it's 3rd diff too!!

My old mans XR6T is pushing out 370+ RwKws and his car is still on the original diff and manual trans both of which have not been touched (other than oil changes), only driveline change has been the clutch which was changed to a cushioned button ceramic unit.

At the end of the day it comes down to how you drive a car. There is a big difference between driving a car hard and thrashing the crap out it, my magna has been driven very hard on the track and has never blown a diff but then there are others on here that have blown the diffs on there bog stock magnas (looks at choonga lol ).

Some batches of diffs and 5 speed manuals had varying levels of quality. A mate of mine had his gearbox go on a stock BA XR6T, and he by no means thrashed the crap out of that car. But I agree, allot of it is how you treat and maintain a car.

Ok ppl, back on topic of the supercharger, I do not have time to delete many pages of dribble, it is simply easier to delete the thread which I do not want to do.

Last I can remember this thread was about a guy using his initiave and putting a super charger on his Magna, lets get back to that now please!

The RPW TT Magna makes 517hp at the wheels, which is well over 400kw at the flywheel.
Internally it only has forged pistons, and basically stock rods and stock crank.
I know alot of money and time has gone into the development of the car, but armed with this knowledge it would be possible to get there for $20k.

Went back to bullet today to get my super charger belt re-tension, they are looking at changing the pulley set up, they are making a new bracket with a high tension spring in it
to keep the the belt tight.
While i was there they said that they would be getting a professional photographer in to take pics for there web site,:D So once the new pulley set up is in the car,
Bullet will then have KITS available for magnas :cool:

Be good to see some cams come with that kit.

The car is going back to bullet on the 31st, they will be putting a new bracket on, it will change the way the belt runs around the alternator,and they will change the belt tensioner to one which has a high tension spring in it to keep the the belt tight,
Was finding the belt would loose tension after about a week of driving around.
While the car is there they will take some pics for the kit that they will put on there web site. :)

The joys of product development. I think we're all looking forward to seeing the longterm reliability of the package. Keep us appraised of the the ongoing package reviews if you could - it's means Bullet are focused on getting it right, rather than panicking because something is wrong. Other companies can certainly learn a lot from this welcome philosophy.

hey question, is it still running the stock headers? btw nice car made smick install :thumbsup:

Yes it is, the exhaust is stock, only the rear muffler has been changed, the motor and gear
box is completely stock as well.
But i do have plans to change this down the track, but i am in no hurry,as it goes quite good as is.

You may have notice that the link to the u tube video on page 11 has been deleted,
I have made two new video's which i think are better than the first video i made, i will
post up the new ones.

EDIT: no video links thanks

enjoy.

Sounds great, BUT WHERE IS THE DRIVE BY?:rant:

No good listening to it idle.


I do have a very very short clip of getting under it in first then backing off, only about 20
seconds long not sure if its worth posting up, I will make a drive by clip after it goes back to bullet and gets the pulley set up sorted out.
Then i need to have a service done, i can tell my plugs are on the way out, and needs an oil change once this is all taken care of i will make a video,

i will post up the short clip if people want to see it.

Sorry about posting my you tube videos in this thread :redface: , i have now put them in the

Hey.

Any ideas how much just the intercooler cost you ?

I may be interested in something similar

I heard that all bullets guru installers left yesterday and they are left with just 2 staff now and have stopped magna kit development.

I can confirm this however they only had 1 fabricator... luckily it was just after my mates x5 had been completed enough and just requires fine tuninig...

will be good to see a comparison once the raptor kit is up and running..

still be a kit for the magna, He told me that they just were not going to do any Rotrex

going to be working for them in the afternoons, Because i was told he will be doing a new bracket on my pulley set up this week when they have my car.

I'd REALLY like to see some pics of the belt arrangement and idler/tensioner. If you're not keen to post them could you PM me so I can make other discrete arrangements with you. Thanks. :cool:


Here are a few pics of the pulley set up a little hard to see all the pulleys,i did a quick
drawing but the angles are not perfect.

Thank you for the pics and diagram. This is one of 2 serious belting options I am considering. What shortcomings are in the current bracket? Is the tensioner spring-laden or threaded rod type?

Again; well done JB and Bullet for putting your neck out and having a go - and a pretty good go at it too.

Which Rotrex SC did you settle on. Did Bullet select or did you go thru the maps with them?

Not a problem, the tensioner in the car at the moment is a threaded rod type, but i want them to change it to the spring loaded tensioner so it stops losing tension, and they are
also adding a new bracket to change the way the belt wraps around the alternator.
I let Bullet pick which Rotrex was installed, they went for the C30-94, i think one reason was the HP it makes, and the physical size of the Super Charger, they had to consider how much room they had to mount the Super Charger and set up all the pulleys, hope this helps you out, i will take a few new pics when i get the car back so you can see the way the new set up looks.
