RPi stage 3 update

I know its been a while since we gave you guys an update for the stage 3. Initial testing for stage 3 gave us a 12whp gain. I met with Chris, the owner of GPower today and I am trying to work force induction into our stage 3 set up. Stay tuned.

Does this mean 12 rwhp over or in addition to the stated gains of stage I and II?
Meaning if one had stage II you'll get an additional 12 rwhp?

Thank you

Ranger

as stock m5= 395whp on rpi's dyno... 500 is the manufacturers claim to stock hp to the crank... you then can make the calculation 500/395=1.265823 which could be used as a basis of converting whp to crank hp (assuming similar conditions of course)... a stage 2 rpi car such as kenny's typically sees around 450whp. multiply your 450 by 1.26523 and you got the estimated crank hp which comes out to 569.62035... add 15 hp for the water meth kit and there ya go

another solution could be to ditch your exhaust and go with the rpi setup for more proven power...lol

lol, just an rpi fan and satisfied customer... Have also seen most of the competitors exhaust dynos first hand and youll be suprised on some of the power losses... i think one brand had a 20whp loss if i remembered correctly! thats a 30+whp turn around from just switching exhausts!
