Engine RPM and load

Steve, you'll need the boost of a good tuned pipe to make that come to life.  Trust me, I've "been there done that" with the 590R.  It's a great muffler, but not anywhere NEAR the boost you'll get with a real pipe.  
    You should turn that three blade at least 8000 or better to have it be really effective.

>  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.
