Hi guys,
So the general rule is that the maximum CR for a street car using street fuel should be about 11:1.
How come forged pistons can have higher compression ratio? And would it not cause detonation?
The only thing I can think of is that cast pistons may crack under pressure where forged won't, but what happens to tuning when running 12.5:1 on pump fuel and forgies?
Also, at what stage are forged pistons worth it?
Is it only when the rev limit is raised for higher rpm/power?
