yeah, but with the discrepancy in the numbers (220 vs 250), i don't think that you want people getting the impression that the sti puts down 60 more whp than the evo.

Comparative Performance of EVO vs WRX STi

If you believe all of the test data being published in Motor Trend and Car & Driver, I don't think the horsepower on the EVO can be greatly overstated. To run a 13.08 or 13.6 whichever mag you believe, requires over 300 flywheel horsepower for a 3260 + lb car. Is there reason to believe that there was a "supertuned" EVO used in those tests?

STI Turbo is Equivalent to a 14B, it can't even hold 20PSI to the RED on a 2.0, immagine what happens with a 2.5....

On our Dyno Dynamics dyno, stock EVOs put down 195-205whp. STis, tested under similiar conditions on the same dyno, put down 215-225whp. Stock EVOs w/XEDEs (Stage Subzero) typically put down 215-220whp. Stage Zero EVOs have been putting down 230-235whp. Stage Ones are making anywhere between 245 and 255whp. All numbers on 91 octane and off our dyno. Other dynos will read considerably higher.

Heh, yeah, they like tons of boost like they like piggyback computers I love WRXs, but it's too funny how they reject mods @ all costs hahaha.

No way, AWD launches totally ruin any hp to weight "bench racing" and mid low 13s is totally possible with a car that has considerably less hp than "300"
