You're correct Stan. The BSAC numbers are good, and when analyzed with the corresponding A/F ratios, indicate the engine is currently optimized for as much fuel economy as possible right now. The number I find surprising is the volumetric efficiency, given the massaged large valve head and cam lift, I would have expected numbers at or close to 100% below 4500rpm. I still think a bit more fuel, perhaps just on the secondaries, would provide a nice jump in horsepower.
