<DIV> Yes the pipe would make a difference, it has plenty of pull and ran perfect I was just wandering if there are good #'s for load and heat= RPM.</DIV>

<DIV><FONT face=Arial size=2>I bet it has a lot to do with using the muffler. Lance is using Dave Lockharts repitched props to 15.75x12 prop on his and gets I think above 8000rpm with the Mintor pipe. Maybe he will chime in here.</FONT></DIV><FONT face=Arial size=2>

<DIV> I'm flying a Mintor 170 with Bolly 590r muffler does great, but I tried a 15 3/4 X 13 3 blade and it only tached 6800 on the ground, it pulled great and slower downlines by a little, my fear is of over heating and loads, even though it didn't show any signs of either, oh all this was do with Coolpower 15% and the temp was in the high 70's, I'm using a 17 X13 normally that tachs at 7600 to 7700.</DIV>
<DIV> Thanks in advance </DIV>
