    Good Link

    Thanks Woody

    The bottom animation is excellent!

    It shows how the fresh fuel/air charge goes out into the pipe and is pushed back by the pressure wave before the piston closes off the exhaust port. This is why a tuned pipe is so important. And why rpm, pipe temp, length, & compression, are critical to the tuned pipe.

    This is also the reason a single pipe has a problem. Two exhaust ports open at any given time. Back Pressure is important so you do not loose to much fresh fuel air mix out a stock or ported exhaust port.

    Get all the details right - and you get Great Power.
