I do have an engine that produces 186HP per liter?the one in my 750 MV Agusta
Senna. 140 horsepower at 12600 RPM. I promise you that every one of those
ponies counts. 60 lb-ft of torque at 10500 RPM. Scares the crap out of me. I?d
buy that a TR motor could produce 200+ HP if it revved to 10K. Failing that,
not so much. Certainly not with a two valve, non-crossflow head with cross
sections that looks like the casting was molded with plumbing parts. 200HP at
6000 rpm is 175 ft-lbs of torque. I think the most recent engine build for
Peyote by Tony Garmey at Horizon Racing was about 140 ft-lbs peak, and it?s
89mm with all the goodies.
