Default RE: Lower Crankcase shape.


ORIGINAL: Hobbsy

Mr. Reivers, please allow me to use another, ''for example'' and then you can tell me if I'm understanding this correctly. If one were to set up a slow turning torquey engine with a stuffed crankcase and high crankcase compression the result would be high speed flow velocities through the transfer ports which in a slower turning engine could result in much of the fuel/air mixture flowing right out the exhaust port. Does that big long sentence sound logical? Thanks, Dave
The solution are tuned pipe and timing of the engine.
