Seen this in my Travels today. Not at Dyno-Comp. I really dont know what to think.

This is a STI with a c32 kompressor.

jturkel

wtf? messed up! what is that in the rear lefthand corner (in the picture) of the engine bay?

MBH motorsports

a big turbo

jturkel

thats what i thought. seems like a rather unorthodox place for a turbo, no?

RLx02

That's nuts. 2 intake manifolds too?

Quicktwinturbo

wow..thats' different

Panzerknacker

Thats where Subaru's have their turbo. They get their rumble from the uneven length of the headers. Of course the axis of the turbo on a normal subie runs long ways so that one is rotated 90 degrees. Guess they are trying to take it back to the old days of group B rally where some cars were both supercharged and turbocharged. When you got a snail as big as your head you need something to provide boost at low-mid range RPMs.

Found this one over on the subaru forums. Dynoed at 443 whp. Info on the build http://forums.nasioc.com/forums/show....php?t=1688562

pretty sick, but that's like hanging 90lbs to one side of the car and not the other. a big no thanks to the handling. lol

Panzerknacker

True but dont most of us sit on one side of the car, not in the middle? So you are splitting hairs lol.

hooleyboy

It just does not make sense to me to have the car supercharged. You can have a big powered Subie without a supercharger. I'm with Frank on this one, no thanks.

I was just commenting that its unique. If my legacy wasnt under warranty I could be making 400+ hp with bolt ons. No way I would put a SC on my subie either.

Mini was working on a dual FI set up-SC and Trubo-there are (unfortunatly) a couple here in MN-they do make decent powa-and they are unique. Real powa freaks go with a small snail (K03 or T3 set up) and a fat 72mm+
good find!

AMS Performance

Seems so much easier to just run an aggressive ball bearing turbo, that would take care of most of the lag issue, seems like way too much weight on the front of the car, that thing must understeer quite a bit.

+1 for uniqueness though

rockjock

fail boat....classic....

I agree. A well sized turbo will spool soon enough and all the added complexity of the SC'er is not going to help except off the line in 1st gear. The porky Subey's don't handle all that well anyway. They tend to be a point and shoot car with lots of power and 4wd to help put it to the ground.

This setup is not that un-common. It's called compound boosting. The theory is that by adding the supercharger you in essence enlarge the engine. Tuned properly, a once 2.0-2.5L engine is now acting like a 3.0-4.0L which reduces turbo lag by a HUGE margin. It's very popular amongst the newest generation of "time attack" cars.

jturkel

driven a modded STI (the one in my avitar actually lol), but never really looked in the engine bay. thanks for the info!

mkonei

their "rumble" is a trait of a "boxer" style engines firing order

AJBoost

Actualy Panzerknacker is right. There are tons of companies who sell equal length headers. When installed, the trademark subaru sound is gone. Infact, the sound is just like any other 4cyl car on the road. Think honda/toyota/mitsubishi.

Also, porsche engines are boxter motors and do not have that muscle car rumble.

looks cool..but no thanks.
