Here a mock up with the engine. The engine could be build in 3 way, stock, custom and competition. The competition one has a blower.
So I though this is a crazy idea to put a V8 on a lawn mower, so why don't make a good crazy job using a blower... And after, I remember that I saw a engine with two blowers, so two it is better than one, and I went in this directions...
Let me know what you think...
