Max CR with R-cam and 98?

Post by Miksa89 »

What is max cr with R-cam and 98 fuel?

My options are ~11.4 with 0.8 gasket and 0.8mm squish,
~11.2 1mm gasket and 1mm squish and ~10.85 with 1.2mm gasket and 1.2mm squish. :shock:

I'll stick my neck out and say that you could use either one of them. And the difference will not be that big.
The squish distance might be a more important decision, but the size and design of the squish surfaces together with CR ratio will influence what distance will work best.
There are several threads discussing squish on the forum but they are all in Swedish.

Thank you for your reply. 8)

I put 1mm Elring gasket and CR is now 11.15 and works fine with 98 fuel. :thumbright:
