whats up guys im new to this and need some help. anyone good at compression ratios?

 

making them, or calculating them?

 

ive got keith black pistons and the ratio with 76cc chambers is 9-1. im trying to find out what the ratio would be with a 64cc chamber

 

An internet search for "compression ratio calculator" will reveal all.

 

I have 11:1 TRW pistons with 76cc chambers, according to combos other guys run, if i went to 64cc, my CR would jump from 9.4:1 to close to 11:1.

But use the calculator, it will help you figure it all out. You need to know a bunch of stuff, like gasket thickness as well.

 

thanks ill try that

 

I use this chart to help me.
