I would agree with you Chads, belt technology does not exist to make a rotor belt that can transfer 375 +hp constantly and survive. Hence the CVT drive. look in a 9860STS operators manual and you will find the mention of a little yellow warning light that comes on and warns of impending rotor belt over load if current operating conditions are continued.In other words get the spare belt and the wrenchs out.
Aw, cmon, a guy can dream can't he;0) Just sayin, belt technology is currently pretty much maxed out, and if some company needs to go to higher HP drives, CIH has the system. Chads
