ok. not a new car, but here is what to expect in the next couple of months.

[size=14:ec3ebab270]BRAKES:[/size:ec3ebab270]
we have managed to source some 362x35mm Xdrilled / Slotted disks with some mo-fo big-arsed 6pot callipers. :D (take into account, that the V8 Supercars run a Brembo 360x35mm disk ;))
altho not a 'off the shelf' kit for a magna, AP racing will supply us with the hardware from a EVO 7, for developement purposes. the main aim is to fabricate the mounting brackets and relivent braided hoses, get a engineers cert (and get everthing else cirtified while im at it LOL) send the 'findings' back to AP so then APR will have a reference for anyone with magnas wishing to add larger brakes to their ride. SO this is really a big step for all of you guys in the future of brake mods.

now, if you get your rulers out, 362mm is big. bloody big, so big infact, that a 18" wheel will only JUST fit, but recommended 19" :D >> but wait, there's more. our developement will also include the design and fitment of a rotor of 300 and 330mm sizes. for fitment in 17 and 18" rims respectively.

initially, the fronts will be done first, and rears will follow in later months, as the rear needs more intense engineering as it incorprates the handbrake etc.

[size=14:ec3ebab270]ENGINE[/size:ec3ebab270]
Expect to see further HP increases as we fit and tune a Stage 3 Cam (not sourced from RPW). we expect to see around a 50hp increase and a rev limit around 8000rpm.

Exhaust will be ripped out and a 3.0" mandrel bent custom system will takes its place. we expect to see the torque jump through the roof.

MIVEC head. Sourced, and awaiting arrival from the land of japan, by adding the M.H we again expect to see huge gains mainly in the top end. RPM limits beyond 10,000 rpm and power curve to extend to 8500-9000 rpm isnt out of reach.

LSD will be sourced, likely the 1.5 way. altho the 2way LSD isnt out of the question.

we wont go too much more into detail, but will keep you all informed as we go by.

you do realise that the handbrake isnt located at the rear brakes so going bigger brakes is as simple as the front. Those brakes are gonna be expensive. Btw. i thought u were going turbo? upgrading the cams is a waste if you are.

are you still working on a magna or you gone a honda?

Sounds good booya..

Just a question though.

Why are you getting stage 3 cams when you're getting a MIVEC head? You wont be able to use them, the MIVEC has it's own special cams and it's DOHC...

maybe for development, so they can offer them to other magna owners in the future

D'oh! ive confused myself already :lol:

ok, lets try again. ill use the Stage 3 cams if the MIVEC head doesnt work (which there IS some doubt) >> i never mention'd anything about the cams + mivec did i ;)

the handbrake on a magna is the inner drum of the disk. so yes, there is a but more fiddling round'

[quote:c385771248] thought u were going turbo? upgrading the cams is a waste if you are. [/quote:c385771248]

turbo has been scrapped since the start of this year. we will continue to build a N/A gob-smacker. i wouldnt be surprised if we upped the compression further :shock:

[quote:c385771248]are you still working on a magna or you gone a honda?[/quote:c385771248]

what suggested Honda :?: :-k

Starting to wonder if some of these are high hopes.

10,000rpm? Mivec or cams isn't going to make this magically achievable. Are you doing / done anything to the crank?

And why bother if peak power is still around 6k rpm or even 7 or 8? Sure, it will sound insane but won't be of any benefit apart from probably being beautifully ballanced around 5-7k.

Any difficulty envisaged with the ABS system?

Disc size for rear? Are you doing a weight and balance study of your car at full brake loading? This might save you plenty cause the rears will be tiny in comparison.

Hmm just fit into 18' huh. Might make it difficult to sell to people who can only just afford (legally) to run 18'.

Good luck my good man and love to see them filling your rims.

Colour of Caliper? Colour of Disc?

More labels to stick on your shopping list?

if you can get a magna to rev and hold peak power beyond lets say 8000 rpm. you will be faster. how? well by not spending time changing gears, and being able to go further, with the same effort. hard to explain. but lets put in in perspective.

when i went down the strip. by the end of the 1/4 mile i was in 3rd. wow. no big deal. most cars will be in third. ok, but you can extend your revving range by not looseing accelleration or power and be only in 2nd gear by the end of the 1/4, then you will have a faster time, as you dont have to spend time shifting to third. hope you understood :S

once we have the rear 4pots installed, a brake bias will be installed and trial and error the settings to get the optimum braking distance. to my knolodge one of the best braking cars is the E55amg, which can go from 100 to 0 in less than 30m. i hope to rival that :badgrin:

[quote:af7e527259]Any difficulty envisaged with the ABS system? [/quote:af7e527259]

they apparently do work with ABS vehicles. one thing to menton also, for those without abs, upgrading the quality of your brakes is almost a ABS upgrade. with better pads, and quality calipers and rotors, no matter how hard you jump on the stop peddle, it very rarely locks up. a good example is a V8 supercar. they *rarey* lock up, but have no such ABS controller.

[quote:af7e527259]Hmm just fit into 18' huh. Might make it difficult to sell to people who can only just afford (legally) to run 18'. [/quote:af7e527259]

thats why we will be trial fitting other size rotors for 17" rims upwards.

[quote:af7e527259]Colour of Caliper? Colour of Disc? [/quote:af7e527259]

from pics ive seen, the calipers come in red, yellow and black. the disks are silver with outside black.

[quote:af7e527259]More labels to stick on your shopping list?[/quote:af7e527259]

i dont have a 'shopping list' on the side of my car :p

i just finished reading an article in one of my hot 4s magazines that described the best way to increase power and speed in a naturally inspired engine is to increase the rev range-they used F1 cars as an example as they have the ability to produce 750hp atw+ and being about to rev 15000 revs+

Your such a bad influence Booya :lol:
How do you afford all this stuff?

Go get em tiger, good to see someone with enthusiasm around here mate.

Increasing the rev range is a really good idea for drags, as you could keep it in the upper power band more easily.

Allowing an engine to rev higher is only one factor in the equation. Power is a function of torque at a specific engine speed. There is no point revving to 10000rpm if you don't have any torque left by the time you hit 7000rpm, as 10000 * bugger all is still bugger all.

As I understand it, engines are designed to produce peak torque at engine speeds that are found in normal cruising to enhance drivability, and peak power at a point just before the engine explodes.

So unless you radically change your engine configuration to elongate your torque spread, or skew the torque spread to the right (leaving a hole at low RPM), just making an engine spin faster isn't going to give you the power hike you think it will.

Case in point, the 3.5L engine is rev-limited to 6700 rpm, but peak power happens at 5400 rpm and falls quite rappidly above that number - the reason? The torque curve peaks at, what 3400 rpm and falls off from that point.

disclaimer: I am an amateur ;)

double disclaimer: this isn't aimed at you, booya. cos you are changing the engine to suit :)

if you can get a magna to rev and hold peak power beyond lets say 8000 rpm. you will be faster. how? well by not spending time changing gears, and being able to go further, with the same effort. hard to explain. but lets put in in perspective.

when i went down the strip. by the end of the 1/4 mile i was in 3rd. wow. no big deal. most cars will be in third. ok, but you can extend your revving range by not looseing accelleration or power and be only in 2nd gear by the end of the 1/4, then you will have a faster time, as you dont have to spend time shifting to third. hope you understood :S

I see what you're saying but once you well past the peak power, shifting up a gear where you're heading up the torque curve will mean you're accelerating faster than what you were.

80kph on second is about 6000rpm. Going to 10,000 rpm even won't get you over the line in second.

And a 3.5 has peak torque at 5000. ;)

no dyno sheet to prove, but if you want to accept my findings so be it.

last roll on the dyno before it "jumped off" they dyno shows

229.4hp @ 6100rpm
1900something pounds of tractive effort at 5500rpm.

peak power holds till 7000rpm, torque drops off around 6100rpm.

so really, by the time i increase the size of the exhaust, and cams/mivec we should see those peak figures incrase.

but to save this arguement. lets just wait and see what these mods do.

with the help of my friendly neightbour hood bank manager :lol:
(jokes - all work is paid in full - loans are bad... mkay!)
hopefully you guys will be able to play with your own engines one day, knowing ive done the hard yards and emptied my wallet first :lol:
again, i love to see you guys mod your cars one day with a 'booyamotorsport.com' sticker on your windscreen :D

Your such a bad influence Booya :lol:

His parents bought him the car, he only pays for mods.

a booyamotorsport sticker on my window??

how self-indulgent...

I'll pass.

Nice work, keep me posted mate.... im on ur tail :p

nice work ben, let us know how these cams go, who's made the cams?

yes, but actually to twist the story further,

i did have to take out a 'small loan' for the 'car' only so that it gave me a kickstart with a credit rating :D

so yes, i did pay a small amount for it... credit rating purposes :D

hahah.. but all mods are paid in cash with no loans etc.

go for it booya, I just hope your engine hold together beyond 7,000rpm :shock: , I have heard these engine become really fragile after about 7,500rpm, so rebuilding it from top to bottom to suit should be your first task on your to do list.

I like what you have done so far with the mods, maybe look at strapping the car down on the dyno to get a more accurate reading?

it got rebuilt when we went high compression ;)

engine rebuild on a 61,000km engine :P

the 6g72 engine is a very strong engine, but all simple things, im more then confident Dallas would of though of while doing these bits :P


MORE UPDATES:
looking at 200hp hit of NO2 ;)
and
further upgrading suspension to include front and rear swaybars, antilift kit, strut brace and camber kit.

You had all that power and you didnt have a strut brace ??? Holy crap man, torque steer would be insane!! But i guess you do have some huge ass tyres to keep it on the road. How did you keep that beast in a straight line?
Nice work with your car btw, good to see someone really going to the extreme with their magna. :D

sounds good- eagerly awaiting the results, but even tho engine was rebuilt, when you go to massive rpm, unless you have balanced crank, conrods and pistons, she could blow!
Also re the brakes, I think you will find that bigger brakes without ABS will actually lock up sooner than smaller brakes if you stomp on them, the reason race cars rarely lock up is because of the drivers skill - you still see em slither off the side when they lose it :( :D

intresting, as ive found that the more power i get, the less torque steer!.. yes very funny. i reckon the t.steer was worse when it was stock!! now, it just launches in a straight line! only 8" wide wheels. downgraded from my 17" which were x9"

:lol: you wont find stock conrods and pistons in the baby!!! :oops:

Awesome work mate, keep it up :)

Hope this stuff is done my MM, can't wait to see the car again.

im hoping to have at least 70% of all that done for my birthday!!! (august) so yer, im pretty confident at least the brake + mivec/cams are done.. oh the suspension and or the NO2 :badgrin: :badgrin: :badgrin:

the 6G72 have been used in sprint cars, holding 10,000 rpm, actually this week the sprint car is being dynoed, ill get some pics etc ;)
