Help With Piston ID
 

The 95P30 are Mahle 3.0 RSR 10.2 CR pistons.

Thanks Tom.

Now the rest of the questions.

I run these pistons with a single plug ignition and presently mix 50/50 110 & 93 octane.

Is this fuel mix adequate for this set-up?
Would I benefit going to straight 110?
Would I benefit going to a twin plug set-up?

Thanks, John

Most experts agree that 9.8 CR is the limit for pump gas. As long as this motor is always using race gas, you are probably OK with single plug.

I would get some expert opinions before making a final decision.
