Compression Conversion
 

How do you convert 210psi into a compression ratio? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

You can't .A wild cam will kill the PSI and mislead .PSI is related to cylinder pressure not C.R.

You're right.
Compression ratio is based on volume,and psi is a measure of pressure.
Although they're related,they are not based on each other.You could fill bicycle tires and car tires to 35 psi,but they both have much different volumes.
