Another SC question!
I'm seeing the most popular C/R is either 9:1 or 9.5:1.
Also what number are being put down with this set up?
Check this one out. We typically shoot for a 9.0/1 compression ratio, but slightly higher sometimes is what we end up with, depending on what head cc/piston combination is available. You don't want to end up with a combination that has a thin ring land on a boosted engine. Bob
