i have specced many good road engine pal, and the cr would nto be any lower than in the 9.0's , yes the restrictor does make the torque curve very early in the revs range, and without it its further up in the rev range, so im not seeing your point ?
the original thread still stays true.
if i was speccing an engine for over 500bhp it would be completely differant, for a start i would decide what torque i wanted and for what application it would be used, but take my word i wouldnt fuck about in the 7's for compression
My point is if you were designing a road car to make good torque at low RPM on big boost you wouldnt use over 9:0 CR on a YB.
If you do, then obviously you know something that none of the other people building YB's seem to want to take notice of IME.
