RE: Best Pressure Tap Location On Tuned Pipe?
Despite some misgivings I ultimately located a 6-32 fitting on the top of the manifold block. The engine ran fine but I haven't had it in the air yet.
I had a chance to tune the system today and went from a baseline of 12300 with manifold and no pipe to a final 13200 with the tuned pipe and manifold shortened about 1.25". I may be able to get a few more out of it. Is there any indication that you are getting close before you actually get to optimum length?
P.S. the sound is a wicked "snarl". I'm going to love this pipe.
