7's every think about a "slippy" pipe?

Would have liked to try it myself. A little short on re$ource$. Some ex-karter turned Wankle lover must have tried it.

A "slippy" pipe is common in Enduro karting to widen/flatten the power curve. In a nutshell the length of the pipe is not fixed and is adjustable while the kart is motion with a spring loaded, steering wheel mounted, hand control. Pull it as the rpms rise, release it when the rpms are low.

The stainless steel pipes with a 1 3/4" inlet are about $200 each. Contact RLV in Santa Maria and tell them you want one built with 3" inlet/outlet and enough flow and a workable range from 5000-8000rpm. When they stop laughing, tell us how it worked.
