Supercharger options?

subbieatnz · #1 02-12-2009, 10:46 PM

What supercharger options are there available to use on a EG33?

Had one guy say could maybe use a Holden V6 Supercharger off a 3.6 or 3.8L motor.
Also whats options are there to cool the hot air charge from the supercharger?
Are there any superchargers with a built in water air intercooler etc?

Thanks

There are a couple of options with both styles of superchargers.. Do a search and you will see.....

TOMSSVX has one of ECUTune's Whipple-based systems for sale

SVXFiles sells a JET system that SVXFiles has been running for years.

Because the Whipple supercharger is a positive displacement device, there aren't issues of decreased mass flow due to increased pressure on the supercharger discharge side due to elevated charge temperature, as there would be with a centrifugal device. This means that an intercooler for the Whipple wouldn't result is a significant boost in horsepower for short duration engine bursts.

However, I think Tom has found that the elevated charge temperature leads to pre-ignition issues when using the Whipple-supercharged engine at high rpms for extended periods. Thus the knock sensor does a number on the timing to avoid knock, putting a real damper on engine output. So if you want to use the engine for drag racing, the intercooler won't get you much. For track work with extended high rpm run periods, an intercooler or water injection or other charge cooling method might get you a a lot of extra ponies.

All I can say is that methanol makes a very significant difference.....

I wouldn't complain if the new twin srew eatons had air to liquid intercooling built in in addition to the built in bypass valve, that's for sure.

Heres a intresting set up

very trick! where did you find the pic?

ive had that pic for years i think. i only just got to sorting some of the 1000s plus of subaru pics i have lol

I know it was off a concept baja thingy subaru did.

more pics of the prototype I think its called the STX

Whats the average methanol usage do you get while driving etc?

I wouldnt know if the LTNZ would allow a road legal car here to use methanol in it, even if it wasnt used as a fuel. I will have to find out about that.
They mite consider it as a drangous item that could catch fire etc and not allow it.

heres a supercharger set up fitted with water to air intercooler.
Only prob its for a holden V8 and most likely be to big to use on a svx?

I checked with my wof man and he reconned the methanol wouldnt be allowed to be fitted to a road legal car.

The main problem with a set-up like that is getting it to fit under the bonnet of the SVX.

Sticking it into the Vee of a V8 or V6 loses some of the height. Also you will notice that system has a long shaft coming past the blower and carrying the drive to the rear of the unit.

In other words the feed to the blower is from the front of the engine. With the SVX you feed from the rear.

Pure water will do the job perfectly OK, without alcohol.

The alcohol mixture that is used is around 50/50, maybe 60/40. It keeps the running cost down. However, there is a double bonus if you can feed the alcohol mix. The latent heat of vaporisation is higher for alcohol, so the cooling effect improves with the mixture. In addition, the meths is a fuel mix, which helps, water is neutral and does nothing else except cool down the compressed mixture. A further help is the alcohol improves the Ron rating of the intake mixture, which retards unwanted detonation and allows higher pressure from the blower.

Pure water will work perfectly OK for a road car. It is just less good than an alcohol mixture, so you may have to run a few pounds less pressure.

I don't think they would call it a fire hazard, washer fluid is methanol/water. My favorite method of cooling the intake charge is Fords SuperCooler system, which has been in two of their concept vehicles, originally introduced in 1993, then brought back in 2003. It uses a tank of coolant cooled by the A/C system ran through a water to air intercooler to cool down the charge. I am surprised this system has not made its way to a production vehicle yet, or at least an aftermarket add-on. Simple enough system, just need to find a way to make it fit. I'm sure somebody will jump on the idea as soon as the patent runs out.

LTSA is werid on stuff. They are alot harder on every one now than they used to be.

So your saying with that system instead of water running thru it it uses Air con coolant
