Thank you Rockjeep. Now I have another question and I really don't want to get into the discussion that is going on in the other forum. Why are sledpuller and diesel tech going at each other. They both scientifically both right. There actually is not any more stress on the engine due to pulling or drag racing with equal motors. And sledpuller is also right the stresses on the driveline are much greater as far as resistance when pulling a sled due to torque multiplication which allows you guys to pull the loads you do and that is why you break driveline parts. And one guy said he is pulling 1900hp until he possibly snubs it and he is wrong hp greatly diminshes as the motor is pulled down towards snubbing it. SO Why the testoterone match
