And on the 2500rpm start of the pull, the 195CCs matched the 165CCs for torque. Now, it was a mild camshaft so probably with more cam lift, might have seen an advantage on the 220CC for peak HP. Their results seem consistent with some of Vizards published results if you scale the runner size for displacement.

Glad you found it because I searched and couldn't lol

I thought that one was a pretty interesting comparison.
