Tom you are exactly right, the type ye of power used in truck pulling is different from what is required in drag racing, in truck pulling motors you spin the motor up as high as possible to start the pull, and as the weight and bite come in the motor pulls down, in drag racing the engine has to have the ability to Rev-Gain or accelerate up. I heard of one of the big shops truck pulling 5. 9 Cummins making 1400 hp, but the dyno operator said that the 30 seconds need to spool and the copious amounts of smoke would have precluded it from ever being a drag motor. When the same motor was subjected to a acceleration pull, the results were different, the motor made a little over 850 hp. a loss of over 550 hp, in a Pro Stock motor the motors make around 1350 hp on acceleration ramps, at a steady pull they only gain about 25, this is due in that in drag motor we tune towards acceleration rates, even go as far as having different timing curves for each gears acceleration rate. The work going in our motor programs are geared towards the same goal. I also believe that all the smoke is a primary factor of lazy motor, a team we use in drag racing
Tom I have great respect for what Jeff has accomplished with the white truck in the past, he has helped diesel motor sports along greatly. I was confident from the splits, and potential gains that Jeff’s truck could have run a mid 9 second pass. I felt that there wasn’t any track there,, in reality the track that Sunday was terrible. I had a hard time getting a hold of the track after the 300 foot of concrete from the 300 foot times thou I am sure that my pass there would have been a mid 8 second run , had the track been there.
