I'm missing something. How do the return pulses from the
pipe go through a turbo rotor that's spinning the wrong way?
Mount the turbo on the stinger pipe.
Then the pipe will work just as it did without the turbo mounted just that the turbine will build up a different pressure in the pipe so a different stingerdimension will probably be needed.
Pulses that are in the stinger are "lost" anyway for the engine...
Could u post some more pics plz.This will be the second time I've had this working on this same scooter. The first time it worked just fine mounted in place of the silencer. It spooled up at around 10000 rpm's or so. I didn't dyno the old setup, but it would easily get to 80mph at less than half throttle. With the taller tire I'm running now and the the extra revs from the polini pipe, over 100 mph should be easy.
hi mate it runs off a piaggio oilpump belt coming off the ignition system with a special nut
