I just blew the 1st rotor pushing about 1.2 bar in third gear @ 7000rpm. I earlier rebuilt the motor myself but now am wondering if it would be best if I just bought a fully built motor. Maybe I didn't do the best job on the rebuild/porting. Who's running one of these crate motors? Is it worth it? I am running a greddy TDO6 with an autronic stand alone. It was pushing over 320 before I blew it. What kind of power and how much do you think the crate motor can handle? And which company would be the best to go through at what price? Any advise would be greatly appreciated...
