ORIGINAL: flyinrazrback
Are there any pitts style mufflers available for the MVVS 45? anyone have any experience running this engine on other than a tuned can?
I'm confused. I know from other discussions that flyinrazrback would like to use a tuned pipe, but the original question here mentioned a tuned can, and flyinrazrback's approximated losses of 300-400RPM are reasonable for a tuned can vs a low restriction(relatively) pitts-style exhaust....but Dick started quoting losses relative to tuned pipes.....so what's the real question, relative to a tuned can or a tuned pipe?
Assuming it's the original question, flyinrazrback I think your estimate is in the ballpark....but since the 45 develops its power at a relatively low RPM, I wouldn't be surprised if the loss is on the lower side of that range.
BTW, if anyone has a ZDZ 60 Bisson muffler they want to send me, I'll test it out and send it back. Really. The results would be very interesting.
