pipe tuning vs nitro

[Dean Pappas]

Hey Anthony,
More nitro widens the pipe length sweet spot. Add some nitro and see if you can shorten pipe.
If you're turning the 15-3/4 X 11 at 7,800 then I'll bet you have no "limiting" problem.
Did you really loose vertical horsepower or just a little bit of level-flight speed?
Dean

Subject: pipe tuning vs nitro



I have been trying to wrestle with a compromise. My current setup is OS rx 
with the little ES pipe and Mac header set to 25" from plug to baffle. This 
yeilds 8000 rpm on 15.75*11*3 on 20% S&W. The power is great but there is 
some spooling issues on down lines and a gurgle on lower throttle settings. 
Lengthening the pipe a half inch improved the manners of the setup but cost 
me 200 ground rpm but in the air it feels restrained. Which of course I 
hate. Am I drunk with horsepower or should I try more nitro to get the best 
of both worlds? Will 25% give me what I want? What are most peoples setups? 
Dean and Dave are you out there?

TIA

Anthony
