PI SWAP QUESTIONS???

[stangin_97gt]

i plan on doing a pi swap on my 97 gt, but i want to supercharge it also and don't want the usual comp ratio. does anyone know what type pistons i would need to run to reduce the comp ratio to a more suitable one for s/c apps?

you would need a dished piston.......are you looking for a particular part number?

I have 9cc dished pistons and my compression is 9.8:1 if that helps at all...

With stock bore and stroke: 11cc dish gives 10.52CR, 17cc dish gives 9.66CR, 23cc dish gives 8.94CR according to Sean Hyland. This also assumes stock combustion chamber size of 42cc. Your stock pistons are the 11cc dish.
