Correct it out for RPM and the Hp/cubic inch is around .51. If you take away the liquid cooling, and run the heads at 380dF rather than 240dF, the octane requirement would increase substantially. George """ Hmmmmm.... My Honda VTX motorcycle, 110 ci (55 ci/cyl) comes close to my 320 (80 ci/cyl). It uses a 9:1 compression ratio, 4" bore x 4.4" stroke, 3 valves, 3d mapped fuel injection (MAP, OAT, RPM, etc.) thru 12-hole electronic injectors, 2 plugs/cyl, EI, liquid cooled (uh, well that's quite different), etc. This engine produces 95 HP and 115 ft/lb at the rear wheel thru a less than efficient a drive shaft at about 4500-5000 rpm. It requires 86 octane auto gas. """
