Its even worse on the 41021 manifold..... But basically whats happening is the engine hits a point where the power drops off so much as that it no longer can accelerate the flywheel mass, or at least the acceleration slows substantially..... If the engine hit a specific RPM and was unable to climb any further the graph would read zero... As what the graph is essentially showing is rate of acceleration over time..zero acceleration gives a zero reading.... On this particular engine the 9901 doesn't rev out too well.... however on some other engines it runs like a banshee on the top end.... so it is what it is, the 9901 isn't the best suited to this engine, its not bad, but there are better obviously

Have you done any other pipes, like Alpha, or 2058, 2060/2090 os pipes, etcetera? would be interesting to see the numbers and curves.
Going by this curve the 9901 is a total dud! Explains why I like the 2096 better.

So the green is the rb 2097 at the peak power point? If so, how would the 9886 fare against this?

very tasty work Neal!! When is the new nitro shop thread going to be up if there is going to be one?

Any test results on the two new conical manifolds?
Matching the manifold on the pipe side seems to give good results.

Unless you are collecting them, I won't pay more than 150 for them, for 2 reasons, you can get a P5 for 215 that has a better rod better carb and better front bearing... abd 150 is a brand new price and being nice cause it's new...
