I have tried to work out the ml of the dish in my STD 998 dished pistons.
I got 6.9 and 7ml Tried it twice does that sound about right?
Anyone Know The Volume For Std 998 Dished Pistons

Are they the 20773 pistons? If so I believe that these are 6cc

Wil_H I'm not sure, will it be stamped on the piston? I need to give the CC to BenRoss for some head work as I need to lower the CR ready for my SC12 kit..

On a 998 every 1 cc in the chamber equates to a change of around 0.2 in the CR.
So, if you use 6.5 in your CR calcs you'll be on the safe side (i.e. slightly lower CR).
If it helps, I've always used 6cc in my calcs for all the various 998 pistons I've used.
