hahahaha.. Scott.. the STi is NO WHERE near its factory limits..

theolder STi's ran at 17.5 PSI .. this one runs at 14 PSI .. hell of alot more power to be had in this car.

I've yet to see a Cobra pick up 100 more RWHP from an $80 pulley.

i've seen them pick up about 30-50 from a 3.1 pulley costing about $280 with pulley puller

the Cobra is still more moddable than the STi though.. but what can be done with that forged 2.5L remains to be seen..if its anything like the older 2.0L STi blocks.. expect some large numbers once tuners get their hands on it..
