What gears are you guys running and with what prop at what RPM.
Im just trying to see the different combos out there?
WFO, Find out what kind of Horsepower your motor makes and then you can make a gear call. Also, if you are running one of Joes props they are typically pretty grabby. If you are pushing 1000hp, you should be around a 22 to a 29. With the ProGas motors we had over 1240hp and ran 18's but that was naturally aspirated and weak on the bottom end. If your motor is making 800-1000 hp I would put a 15-18 gear in it.
