come on ppl, this is a common setup, help me out here

It depends. What color vacuum hoses do you have, and what brand of DOT 5 fluid are you using?

hm..... not funny... i just copy paste, evil, you could help me out instead of joking around

Evil Aviator 03-28-05 06:05 PM

Hehehe.

Seriously, there isn't enough information given. However, it would probably be somewhere in the 300-500 peak hp range, and the peak torque would depend on the tuning and boost profile.

the guys who owns it claims 380 hp at 10 psi...
BS, right?
not even with all the tunning in the world

i can't begin to guess what hp the specific car is making for obvious reasons.

i can tell you that all turbos have a Limit as to maximum hp on gas in a rotary application. that's because all compressors reach a brick wall at a certain airflow rate. based on that i can tell you this....

the To4 S3 ( 1.903X 2.75 compressor wheel) will flow 37 lbs/minute tops... from the compressor map.

when combined w optimium fuel and various support systems that 37 lbs/min of air will make: 284 rear wheel rotary hp.

HKS markets a To4S which uses a 2.3 X 2.972 compressor wheel. i don't happen to have a max flow on it but comparing the wheels i end up w approx 47 lbs/min. assuming 47 lbs/minute that compressor would make tops 361 rw rotary hp.

keep in mind these are approx maximums.... that assumes excellent tuning etc.

380 at 10lbs not even to the flywheel. Might be able to get these numbers if you leaned out the fuel on the dyno. Some people do this for third gear pulls on a dyno to hype up their numbers. I have seen it work twice problem is on the street you will blow the motor like this.
