Breathing Fresh Air (finally)

You'll get better results using a smoother style flexi pipe. The smoother the pipe the less turbulence you'll get, which means you'll get more air to the engine.

this pipe will flow the same if not better than a totally smooth sided pipe of equal diameter. Think of the surface of a golf ball Anyway good work

Thats some ghetto ducting right there beeza. I love it haha!

I think it's a little more complex than comparing golf balls to internal airflow in a pipe. Golfballs have dimples so that its wake is alot smaller than if it had a smoother surface, this is because the boundary layer on a dimpled ball is turbulent and allows air to 'curve' around better.

If the piping was smooth, a smaller friction head would probably be calculated resulting in a lower velocity loss around the bends esp. of course it would be more expensive to buy custom smooth piping :P
