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.

Did they test at different acceleration rates, or just 300 rpm/sec. Would have been a prime opportunity to test at 300, 900 and 1500, then I am betting the results would gave been more varied
