I made this today, its 83 cubic inches, 4 cylinders, uses the Hayabusa bore and stroke, and the crankshaft is about 3/4 of an inch to one side such that the power stroke occurs over more than 180 degrees of rotation. This engine would vibrate badly from complex secondary oscillations and the primary oscillations would be turned into a twisting motion with parallel-aligned offset crank counterweights. It makes like 330 horsepower and revs to 15000 rpm, and only makes like 140 pound-feet of torque. The car its in can hit about 221 mph, its basically a fatter and far more aerodynamic classic Mini Cooper.
