Q for lizzyfan or any other blown/pi swapped sn95
What numbers are you putting down with your car? How much boost, timing and what octane? Did you happen to install the blower before your meth kit?
Reason I ask is I am going with 9cc dish forged pistons in my rebuild and you have the pi swap, sowe shouldhavevery similarcompression ratios (sn95s have 9cc dish pistons right?). Im curious how much boost it can handle with the approx9.7:1 cr before detonation occurs.

RE: Question for lizzyfan...
I have the PI swap and heads were shaved when i put differant valves in. So my compression is around 11:1 so supercharing it w/out touching the bottom end you would only be able to run like 7 or 8 lbs. Now if you change your pistons to match the heads so you dont raise your compression but still add HP that would be the way to go and put a s/c on top of it.

RE: Question for lizzyfan...
What do you end up with for a cr with the pi swap? Its mid 9s right?
the 9cc pistons should put me around 9.7:1. With a slightly thicker head gasket and some possible combustion chamber workim shooting for maybe 9.5-9.6:1.
My setup will be aforged cobra crank, modmax h beam rods and modmax/cp 9cc dish pistons, port/polish headsand comp 270 cams. Itll be an n/a setup for a while and possibly fi later down the road if I dont sell/trade it first. Just trying to figure out what kind of boost I can safely run on 93 octane pump gas later down the road if I end up boosting it.
