I really like the idea of a high-power, high-rpm, low-torque engine in a lightweight car like a Rover Mini or Smart. The Hyabusa with a turbo being the way to go !
I never did though, see the point of the opposite, a bloody great car engine in a bike, but it does happen. (Imp-engined bikes, Reliant-engined Quasar, Munch Mammoth, etc.)
i could see myself building a road going quad or sand buggy using a big bike engine but same as you why squeeze a V8 into a bike??? theres a lot better uses for a nice small block engine
Talking of Dune Buggies, I was at a place called Glamis last year, (look it up, it’s well worth it) and was tootling around on my Yamaha 350 LC-engined quad-bike, looking enviously at all the monster stuff on ‘Competition Hill’ and along comes a truck. Then off comes a Dune Buggy with 1000, yes 1000 bhp. OMFG.
Absolutley ridiculous, with huge ‘paddle’ tyres for insane levels of grip in the sand.
That thing flew up the 1-in-3 hill like it was descending Everest.
