Thread: 90mm

I'm going 90mm with the cp 12 .5.1 piston and going with just the chamber job and instead of n 1 cams I ll use Sr 16 cams for now. And the tri y header on 3" exhaust and a 70mm throttle body how much HP can I espect

Cue Cliff with guess of 1M horse powers.

1 Million monkey power

Come on its seriuos

what other mods?

200-250. maybe

You think ill see 220 - 225 or is it to much ill all ready. Have 202HP with just Sr 16 cams and Sr 16 piston and. The trI y header

i say 219.

If your already seeing 200whp I think you'll be able to put down around 230whp.

I say this because you making about 100whp per liter, so if you increase the displacemnt to 2.2l and keep the effeciency up to par with what its at now you will be at 220whp, but also opening up the bore will help the head flow, so another few whp from the increased flow....

But it depends if your IM will allow that much whp
