Engine RPM and load

[Wayne Galligan]

I am considering the 3 blade also.  I have run a 17x13 @8150 and the Minter pipe so am sure it should handle the 15.75x13 OK.

   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.
   Thanks  Steve

    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.

       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.
       Thanks in advance
