Re: Tubo S and Mud problems
when you hit a mud pit, and hold your foot down to the floor, the machine will start to lose power, most folks call it "powering out". this is because while you are in the throttle, the clutch is continually upshifting. you are under so much load in the mud pit, that as the clutch continues to upshift and gain gear ratio, the engine wont be able to pull such a high gear ratio, putting a ton of load on the clutch and belt, and slowly bog the engine down. the longer you stay in the throttle, the more the engine will bog down. this is just a poor performing clutch, and cant be expected to work "perfectly" for mud pit racing. you unfortunately have the wrong machine for a mud pit racer. the turboS is geared VERY VERY tall, way too tall for a mud machine and pit racing. also holding the brake and gas at the same time trying to "boost" the machine up off the line can and will cause the overboost codes.
at first as i read your first post it sounded a lot like you just got the belt wet, then i realized what you are doing and i think it could have been a combination of getting the belt wet, and also just a poor performing clutch. you have a lot of negatives against you with that machine and pit racing. (1) trans is geared too tall (2) trans is geared way too high for mud tires and heavy loads (3) your stock clutch is not a very good clutch at holding the proper gear ratio under heavy loads such as mud and aggressive full throttle.
make sure you are water tight, add a lot of spring rate to the clutches and some adjustable weights and you can make it slightly better, but with such a high geared trans i dont look for it to ever be perfect for pit racing. we wouldnt run that gear ratio in any of our pit race machines, i work with a tremendous amount of pit racers, and have figured out what it takes for mud pit racing, and unfortunately that tall gear trans isnt going to be my first pick for what you are doing.
