I was talking to a place that does a lot of commodore superchargers, he said that a popular budget s/c for the commo guys is the 1ggze off a supra. Now I admit I don't know much about forced induction but the 1ggze is off a 2.5lt. One would think that would not provide sufficient boost for a 3.8. However I have talked to a few other places including jap part importers and they also say that they are popular with the holden v6 mob.

Now, if this does work (by perhaps increasing the boost with a diff. size pulley wheel) than has anybody considered it?
If not, why? not enought room?

BTW you can buy one for $350

From memory, not enough room to mount it. Unless you want to pop a hole in your bonnet on the side, which would look crap...

You could mount it on the airbox side running a shaft. Small front wheel drives are done like this

I dont know.. A PHAT supercharger belt and pulley (gilmore drive type) would look rather crazy hanging out of the bonnet.. It would have to go like the powers of piss or you would look like a tool... :D :D :D

very interesting :D

I think you'd look like a tool anyway :) :gtfo:

Looked into this around 6 months ago.

Although the charger is cheap, to get custom pulleys, mounts and brackets + cooler and piping + extractors + relocating battery + BOV + retune of computer or a piggyback computer + dyno + labour = $5000+

All for a few extra kw's as they are more for noise and not power on a 3.5 as they are small -does it still sound like good value ??

These chargers sound awesome though.

Just looked into it...apparently you can run the stock computer, stock internals, don't need a BOV, don't need an intercooler and the piping is very simple since the s/c is located on the TB side anyway. The only drama is the shaft and the mounting brackets. This will all have to be custom made, and this is where it can get unpractical money wise. However, you can gain 25-30%.
If you work in an industry where you have access to a metal lathe and other bits and pieces, then you can possibly make this happen.

BTW: its clutch driven so you have to mount a switch on the throttle body. It is recomended that it kicks in at 1500-2000rpm.

Interesting tell us more! Also have access to a machinist and lathes and other metal things that I dont know what to do with.

How the hell could you mount it on the airbox side of a 3rd gen engine??? - that'd be some fancy belt / pulley work to drive a SC at the oposite end of the ENGINE!

The only way it would work in a magna engine bay is top mounted and incorporated into a custom plennum chamber I would reckon.

I agree. Admittedly my understanding of superchargers is limited, but how do you get a belt to the opposite side of the engine to run it?

Simple......You run a shaft over the top of the engine. Few ball bearings, some fancy bracket work etc.
I've seen this done on small 4cyl. engines that also lack room on the pulley side.
Probably easier said then done though.......We'll see.

I picked one of these chargers for $50. Woot! Woot! The electromagnetic clutch can be taken off if need be. However you can only spin a charger so much before it becomes inefficient. A 2.5lt charger on a 3.5 or 3.8 for that matter would be pushing it. I'm putting mine on a 1100cc hill climb car.

I would prefer to just spend an extra $2.5k on top of the original $5k with Sprintex and get it done tommorow :P

Of course, it won't be original would it?

www.rodshop.com.au specialise in putting these units on 3800 v6 commodores. They do the kits for approx $1900. They say about 25-30% extra with 6psi, and they are reliable. Fair enought our cars are more complicated (shafts, relocating airbox etc), but I can't see it being near the $5000 mark, especially after development and kit availability........

i was puting a s/c on a magna IT was going to stick out of the bonet and was going to cost a round the $10,000 mark for this it was going to have 350kw atw but could not get pistons to take it. the s/c was a kapa vortex running 19 psi with inter cooler and cai every thing was costom made and fitted i had all the parts but the pistons and my car spent a year at the shop so i gave up and got the evo
just remember if your going to s/c or turbo the stock clutch and fly wont last long and you will need good shocks and springs ,tyers for tracksion even if you only run 6 psi

What happened to your old car/bits pomejo?

sent them back and put the money towards the evo

i worked it out for a standard magna like mine the engine output is 155 kw and add a $7000 S/C as everyone has said power increase by 25 to 30% so if i did this i would have spent that amount for an extra 37.13 kw so for me to get it over the 225 kw i'll have a least spend an extra 3 to 4 grand so i dont think i would bother but to have the only supercharged magna in Tasmania it would great.

This would cost no where near $7000. $7900 is the Sprintex and thats approx 75% extra power.

the sprintex supercahrger fitted to my TW VRX AWD provides an estimated (by sprintex) 235kw. For the $7600 installed cost (including the supercharger, piggyback ecu, transmission cooler, cai etc) thats a 48% increase in power from the 159kw it was before. Well worth the cost for the peace of mind you get from getting a product you know will provide what it promises, has a warranty, meets the ADRs, only takes a day to install, and wont require some mechanic stuffing around in your engine bay to see if he can make something fit, maybe work, and maybe give you a 25-30% increase in power.

I'd definetly go sprintex if I had the money. I would only recomend the 1ggze sc for people who are prepared to enter the unknown. What I mean is that it has never been done, no reliability gaurantee, and you're limited to 6psi.

so that 235kw figure is at the Fly and not the engine? :confused:

You're not lining up MORE work for me are you? ;)

The trick is to run an idler pulley and up the boost using the idler. It's VERY difficult to remove the pulley on the SC without shaft damage - ask a common***** owner.

The clutch can be wired to a DOOM button in the dash etc or hooked to the TPS using a Jaycar electronics kit.

Why would you spend $5K+ on an SC system and use a 2nd hand, non rebuilt or tested $350 SC off an imported Toyota flogged for every last breath by a 16yo Jap toy-boy?Get a proven combination with warranty. If it fncks up - it's someone elses problem.

I think the point is that it can be pulled off for much less than $5000

For sure. Why not run an SC for each bank of cylinders! Now we're thinking! Can use a water to air intercooler, it's all starting to sound good.

Nice mining, EZboy, there's gold in this thread. :D

Ive got access to a machinist and tools AND i've got a gutless hi-ace camper that has lotsa room for a S/C :think:

How would ya feel getting smoked by an Ol' Fart in a campervan :badgrin: :badgrin:

I also had a look at the setup of the Castlemain Rod Shop supercharger kit - they are mounted prior to the throttle body, and use a bypass valve on vacuum, but they supply a 'missile switch' type activation for the electromagnetic clutch - meaning you can drive without the supercharger running.

Problem with this is that you are now sucking air through the supercharger without it turning - very inefficient, and probably very restrictive at high throttle openings.

To fit these superchargers onto a magna - probably not impossible, just problematic in terms of safely mounting it (on firewall side, sharing its mounts with the PS pump probably) and getting the airflow through it at high throttle openings whilst off.

I would be using a vacuum signal through a map sensor to activate the clutch, not throttle openings, and certainly not RPM (what happens on deceleration with the gears with the throttle shut - ie engine braking - the pressure from the SC builds up and blows off hoses etc and slips the belt - very, very ugly!)

The pressure measured from a few of these SC installations shows about 3 psi boost - certainly not enough to warrant engine management mods or intercooling (especially when you are sucking through the original AF meter).

The off-boost performance could be improved with a bypass system - either vacuum operated or electronic - sucking through a non-moving supercharger is just plain ugly (although properly set up, the bypass valve could just be a few (2 or 3) recirculating bosch BOV's, as long as the supercharger was operating (spinning) once the vacuum was insufficient to keep the BOV's open. At low throttle openings, fuel economy would not be affected. The BOV's would also keep the supercharger from locking up on sudden throttle closure as well.

The superchager would have to be inspected and rebuilt by a competent person, rather than just bought and chucked on there...

Pipework and electronics isn't that difficult either - 2 bar map sensor and an opamp and a few assorted components, some bends + bosch blow off valves.

Just need a clever place to mount it now...

just to throw some more fuel to the fire, i am going to be getting one of thes, it's chepper and i can get the base kit and manufacturer the rest of the components myself. I have emails the guys and the 3.5 motor for the TL will fit their kits. HUMMM can't wait

does anyone have any DETAILED info on the 1GG supercharger?

Yeah, they are a nice looking kit. By those prices, for the Stage 1 kit it's AU$5,000.

Add freight,import duties and GST, and it's probably over $6,000.

You need extractors, so there's another $600ish installed for Pacemakers, add more appropriately for RPW or their own Stainless Steel headers.:shock:

Not too bad if you can install it and get it working OK.:)

The fact that there's no local support would make things tricky if you had dramas.

Check their forums, the products get some good and bad reviews.

The 1G motor is a 2 litre guys. anyhow spend 5 grand on suspension and tyres and brakes and watch your car fly past the other on the racetrack.

Just one thing with this S/C its not for top end power on commodore its more for low to mid range power so there goes the idea for anyone who wants big numbers out of there car. S/C might be good for the AWD boys.

Been looking at the VS1 Vortech SC for a LONG time here and abroad.

We have a few install options;

1) Mounted as per RIPP kits EXCEPT, with a Water/Air intercooler located between the VS1 and the TB. PWR make just such a gem, available in various lengths and diameters. Even a LARGE ARE-type custom W/A IC to fill up the area of the stock air box and then plumb into the TB with a BOV/bypass valve just before the TB.

2) Remove the water pump, replace with remote mounted Davies Craig Electric Unit. Use the water pipe line between the "V" of the heads to mount the SC drive shaft, using the existing timing belt and pulley infrastructure to drive the SC shaft. Now at the SC end of the shaft have a set of pulleys that can be interchanged to change boost and SC speed ratios. This belt also eliminates imbalances caused by 'adding' extra pulley paraphenalia to the timing end of the motor.

My 5c. I reckon a half-cut cheap ballbearing turbo would make a nice experimental centrifugal. Well f me! There's a dead T04 Turbo siting in my shed!! Look, the cold side is still ok, but the hot side bearings are shot....

I wouldnt rely on the davis craig pump in a daily driven car dads mate on his vk supersprint car and it has been replace 6 times in 2 years so now it runs stock pump with davis craig to run water through the motor after a race when the engine is cooling down.

Something I've been thinking about is how about custom making an intake plenum with the 1ggze intergrated into it? Like the sprintex one (obviously not as efficient). I think it might just fit without too many problems on top of the rear bank. You wouldn't have to worry about the shaft.

I looked at this option as well - possible to do (was looking to do this with an Eaton M90 as per the RPW supercharger kit (which is rip btw)) - If you were doing this, the M90 is a better contender - it is actually designed to be mounted this way, and (most importantly) it has an integrated bypass valve under vacuum...

The cost difference is negligible when you consider that you are actually using the right SC for the job - flow, mountings, bypass valve - and you can easily mount the throttle body to the inlet of the SC - possibly even run the standard piping. Cost for a decent M90 is about $750 or so second hand.

Autospeed has a great series of articles explaining all of the intracacies of supercharging, including a real-world example - you have to subscribe, but it really isn't that expensive.

Yep - there are even kits on Ebay to convert a turbo into a belt driven centrifugal supercharger - thought about that for a laugh :)

I also thought about grafting the turbo shaft onto an angle grinder (geared up) hooked up to an inverter - crazy I know... :nuts:
