I was looking at the standard turbo pistons, and im right in thinking that they are 12cc dish as standard and produce a CR of 9.4.

Then looking at minispares 10cc +40 pistons, claiming 9.4 CR, and after being on the phone to a guy at Morspeed about my 10cc +40 and he said it will make the same CR as standard too.

There seems to be a bit more space from the deck to piston than with the standard pistons, so is the missing cc from the dish taken out of the edge??

std 20731 has a 12cc dish.

have a look at:
