BME 50 vs. Brison 3.2
OK here comes some data. The guy with the Brison 3.2 in the Edge gets 7200 rpm with a Mejzlik 22x10 standard prop with an in-cowl can muffler. At whatever elevation we are at in Chicago (not much), temps between 70-80F.
The guy with the ZDZ-40 in his Edge gets 7600 rpm with a Mejzlik 20x10 prop, B&B can muffler, same conditions as above. My tach in both cases.
