Corrected compression ratio
Posted: Tue Oct 18, 2016 8:41 pmCan anyone tell me if 6.5:1 is a safe corrected comp ratio.
I recently measured the Avanti head I have fitted to my RB225 and found it had combustion chamber volume of only 19cc. Trapped head volume was 20.5cc which gave uncorrected 12:1 and corrected 7:1.
I've removed a bit of material and I'm now at 6.5:1 corrected.
