You'll never know, these four photos might inspire someone to build something stupid...
1st is a dragbike I built for a friend of mine, it uses three 700cc two stroke snowmobile engines,built for nitrous, each just over 100hp without the spray.
2nd is a v8 bike I built for street use, running an aluminium 215 Buick and a Harley 5speed. Got sold off before I got to run it, but I'm getting the itch to build another one.
