RE: FOX .15 Diesel conversion numbers ??
Francis, I just ran my Fox .15 conversion, I had a choice between a MA 9x5 and a Graupner 10x3, I ran the 10x3 at 12,400 rpm. I had a 60 sized Macs tuned quiet pipe slipped over the Fox .15 muffler with a silicon coupler, my neighbor is home. The Mac pipe had no effect on the numbers.
