Attention: TDR Forum Junkies 
Ended up sled pulling in a class higher than i was set up for, all i can say is woww, i thought i was under powered for the modified class but i was wrong, left the line at about 4000 rpm,the sled broke at around 150 ft, track speed between 22 and 25mph and the sled dumped all the weight at once snapping my rear driveline yoke, had a little wheel hop to go with it, i backed out and let the wheel hop clean up and once back on the throttle took off again like a rocket and then the sled broke, bob was right, the tnt tune rocks... i have video but need to figure out how to post it thanks BOB, maybe thats why 37s are not liked for sledpulling...
