Default RE: Tuned Pipe throttle question

You are starting to get the system tuned. What you experience is what is known as the pipe over running the throttle. This is normal. Now for most sport application one would want an undersized carb to try to minimize this effect. But with full wave pipes this will be a feature ( I know I sound like MicroSoft salesman. "thats not a bug it is a feature") you will have to learn to deal with. I sometimes will come off pipe (come down to idle) then bring the power back to what I want below the resonant point of the pipe.

If you did come down to idle and she still was over running the carb it is an indication that your pipe is still to long. Also opening up the stinger diameter can help minimize this.

While on the pipe did she pull good?

All the best,
Konrad
