> t28 will get you around 320whp. im hitting 250whp with my stock t25 at 15psi. and i think the rs will get you around 400whp. if the fuel is there. hp is all in the tune.

Sorry dude but squeezing 320whp out of a T28 is next to impossible. Maybe 300whp if you have the S15 turbo and every supporting mod. I make 320whp-ish and I run a 2871R. The limit on an RS is 350hp so about 300-320whp is realistic. There is no way you’ll get 400whp out of an RS.
