I've been looking around for a ir sensor. I think I've found one its alittle pricey. Ill do some more research tonight see what I can find. Has anyone seen anything like that. An actual belt temp would be ideal. I loved that tx did that write up it clears it up nice. It seems the belt is goin to get hot no matter what when your wot but when your not the more air the better. Does anyone know where to get large 4" hose to run the cold air up to the cab. I've seen corrugated tubing used but i don't know if that the best, possibly causing turbulence in the tube. Any thoughts.
