[QUOTE="Saltydawg, post: 157916, member: 2944"] I got the 8200lbs from Diamond. He said a truck with 550 hp and weighing 8200lbs could do 11 second quartermiles. I said no it can't....its too friggin heavy lol. Has nothing to do with diesel or gas, turbo or not.....simply that 550 horsepower is not enough juice to move 8200lbs down a quartermile in 11 seconds. Drop about 3000lbs of weight and sure it's possible. Gene was the ONLY person I could find reasonably believable times for in the 11 second range. He usually wins the events he attends and is normally the only diesel truck into the 11's. I visited both chevy and dodge race fan sites and all of them mention this guy. He ran an 11.51 in Houston. His truck is HEAVILY modified and weighs 5300lbs. Gas powered trucks with similar modifications and running under similar rules are MUCH faster. This is why Diesels have their own sanctioning body. They havent found a way to keep racing competitive between gas engines and deisel engines without requiring drastically different rulesets. Gas trucks that are allowed to run turbos, superchargers, nitrous and drag slicks are MUCH faster than comparative diesels. Why will a large dump truck outpull a light truck even if the light truck has a higher horsepower rating? Its not an anamoly. The same reason your 100hp tractor will yank your one ton diesel backyards when hooked rear to rear.....gearing and traction. Why do you think Large trucks and tractors run 10+ speed gearboxes? To make sure their engine is operating in the right rpm range they need to move the load. You could take your 350 horsepower diesel and bolt it into the dump truck and it would pull the load just fine if you put the right gearing in the tranny to make sure your engine is running where it makes best power. Your little diesel won't last long doing this but it CAN do it. A gas engine requires much higher rpm's so they also won't last long....but they can do it too. [/QUOTE]
