I have read that a .010 tighter lash was equal to 1pt in compression less for someone trying to adjust for lower octane so would a looser lash be a gain in 1pt cr?
That statement makes far too many assumptions for me to put any faith in it, regardless of the source.
Right. And what "compression"? I guess because were adjusting valve timing with lash adjustments, it must mean dynamic "compression". And of course the collective "we" cannot even agree on exactly what valve position we should use to calculate dynamic compression. All that said, I cannot see it changing dynamic compression 1 pt.
I do know that my motor will blow 5 psi more with 0.004-5" lash added.
