Valve pockets and reduced CR...

[MPO]

Any idea how much the CR is reduced with standard valve pockets?

I suppose the end CR depends on your other measurements. But each valve cut out is about 1cc if that helps you with your sums.

Thanks Carsy, got the CC already, just looking for a ball park figure for typical CR reduction really

I'm sure I've read somewhere that valve cut-outs (2-3 cc's per pot) reduce the CR by approximately 0.3



Just can't find it again to confirm!
