Default Supercharger For 2.5

Does any company make a s/c kit for the 2.5 engine? and if not is there a common s/c people buy and modify? I'd prefer centrifical cause i dont wanna deal with an electric clutch.

There are no kits, but there are kits to come soon. I'm not home but i had a link to one that was centrifical. You do NOT need to get one with a clutch, that's why they made bypass valves.

At the moment though, you'd have to build your own kit.


Seriously though, a centrifical is not much more than a belt driven turbo...You could probably peice together a turbo kit with a turbo legacy turbo that would have better response for low boost. But if your really serious about a supercharger, a Roots or a Twin-screw (lysholm) are much better choices IMO than a centrifical

I know of one company with an actual kit on the market:
http://www.raptorsc.com.au/subkits.htm

Other than that, there are a few in the works, but honestly, you
could probably make your own setup for about a 3rd of the price.
There are several going threads about someone who supercharged
their subaru. I think Reddevil (spelling?) is one of them. You
can search for him.

yea i saw his with the electric clutch. I could go for a twin screw or roots i just dont want one with an electric clutch. I'm also looking at doing a turbo. I wanna find the cheapest most efficent route. This kit looks pretty good for the price. $5300(ish) and heres what ya get: Supercharger unit (8psi), mounting bracket, idler pulley, drive belt, NGK Iridium spark plugs, high flow injectors, Simota air filter, ducting to supercharger, stainless tubing from S/C to Intercooler, Haltech E6X engine management (fuel and timing) with 2 Bar MAP sensor, hose clamps, bolts, boost gauge, intercooler (air to air top mount), Bosch bypass valve

It says makes 175KW@crank(which is approx 240hp) This kit alone would get me extremly close to my goal, and thats only with 8psi. Throw a set of cams and my exhaust and leightweight pulley and i should be at atleast 300hp at the crank. This might be worth it, just gotta see what the shipping cost would be. The only thing that makes me worry is that its from australia so im not sure how secure it is. Or how trustworthy their hp ratings are. Leondal have you delt with this company before? This is looking promising the more i look at it, the raptor company seems to be a good company they make kits for subaru, mazda and some others and their holdens as well. it might be worth the money for how complete it is.

Then you have to add in installation cost and tuning for the Haltech.

Forget about EVER passing the OBDII inspection is your state goes that way while you're at it.

Is OBDII even required? Can't he just get the sniffer?

That raptor kit was the one i was talking about. I didn't know it was such a complete S/C Kit. Though i haven't heard of anyone here using it.

"Kits are not as yet ready for sale, but expect them to be ready for release in mid August 2005."

Has yet to be updated, so I dont think they are ready just yet...

I think in PA they changed the OBDII emmissions. I think now they hook it into the computer and if it comes up with check engine codes it fails if not it passes. I'd have to check with the master tech's at my work but i think i remember hearing them say that once. also my buddy knows a guy from a mopar forum he goes to that lives in australia so im gonna give him the info and see what the guy knows bout the company.
