my raptor 660 thats got 52 hp to the wheels vs my banshee was well even most of the time. My brothers got a 700r putting out 60hp to the wheels and it smoked my banshee. But all my banshee had was pods, fmf fattys and noss cool head 20cc domes. So all in all...Im going to say porting will be the biggest key in killing a moded raptor.
