Does anyone know the piston dome displacement for the Endyn rollerwave piston? 84.5mm bore-size.

I'm hoping it's like -3.x cubic cm....

Which piston? What is the PROPOSED compression ration and set up? I can calculate it.

Well it's the Wiseco/Endyn "forced-induction" piston with 84.5mm bore. They only make one compression ratio for forced induction if I'm not mistaken. And the CR is given as a range because it depends on so many factors. About the only thing I can tell you about the piston is it has a 1.180" compression height and I don't even really know what that means.

I know how to calculate the CR if I just have the piston dome displacement. I measured my combustion chamber volume already (it was worked on).

-8.3 cc, if I recall correctly. You can verify this by doing at a search at http://www.theoldone.com, in the Ask TOO forum.

The one for the D series engine is -6.25cc's. I measured it to be around -6 cc's using a super ghetto technique...I was pretty close!

This is the piston that I have:
