compression drop
Hi all, i've got an 04 mach with a p1sc procharger. its currently in the shop getting stronger rods/pistons because i want it to be safe. My question is if i drop my compression from 10.1 to say 8.5 will i make more power with boost, or just be safer?

RE: compression drop
If you changed nothing else but the rods/pistons then you would lose some HP but the lower compression will allow you to up the boost and let your tuner add more timing and make it easier to tune it safely. In the long run what your doing is the best way to go.

RE: compression drop
I'm only running 8 psi on a p1sc head unit, so i'm thinking i will be disappointed when i get it back. I would like the d1sc but that will be awhile... can i up the boost on the p1sc? from what i read they don't like high boost and the seals screw up or something..
