[QUOTE="Saltydawg, post: 158417, member: 2944"] Ok well it must be me and the entire rest of scientific/engineering community using the wrong formula. I didn't use Patrick Hales..formula. Don't have a clue who the guy is lol. In fact I didn't even bother doing calculations to see if 550hp is enough to push 8200lbs to 11 seconds quartermiles....cause its so far off from reality, calculations weren't needed. Newtons Second Law alone says that 550hp is not enough to move 8200lbs of mass that far in that short a time period. Take a look at this: [url=http://hpcalc.boostcontroller.com/]http://hpcalc.boostcontroller.com/[/url] Its a basic calculator for Hp if you know a vehicles elapsed time and trap speed in the quarter mile. Its not perfect but its close enough to demonstrate my point. Lets take Gene's run from above that Flaboy posted. 11.62et and 119 mph trap speed. We also know Gene's truck weighs 5300lbs give or take a few. Amazingly enough this calculator puts Gene's turbocharged and nitroused truck at 668-697hp. A little research on Gene's truck will show his turbocharged 6.0L Ford dyno's at 600hp +or- a couple without nitrous. Now add the nitrous and you can see where the other 60-100 hp comes from. It would seem that calculator is at least in the ball park...close enough for messageboard conversation anyhow. So now lets plug an 8200lb truck into that thing and use the same et's that Gene ran. According to that calculator it would take over 1000hp to push 8200lbs to the same speeds that Gene runs with his truck. 11 second quartermiles. You may well have run trucks at 11 second quartermiles....but they were either about 3000lbs lighter than you say or you were making a whole lot more than 550hp. If you're telling me Newton's Second Law and Watts definition of horsepower are not applicable then I would expect you know which formula are. [/QUOTE]
