what about using a 1000cc motorcycle engine for one of these… figure tranny and motor are ~250 lbs, and your looking at a solid 150hp if the bike is an 03 or newer and you can rev to 13000 rpms… if you wanna make it rev really high buy a newer 600 and rev to 16k and put down 115-125 hp…
would it be feasible to build though?
