[QUOTE="Shadowgray03, post: 569118, member: 9051"] Horsepower = (Torque*RPM)/5250, changing gears will affect torque and thus HP. When you doa dyno pull you are supposed to do it with a 1:1 drive ratio. If you change tire size or gear ration you in essence change the gear ratio. If you have 500ftlbs tq @ 5000rpm would give you 476hp. If you changed gears your peak tq would likely increase and also peak at a lower RPM. For arguements sake lets say changing gears made it jump to 525ftlbs at 4300rpm you would net only 430hp. These are just example numbers and it will vary greatly by the mods you have etc. [/QUOTE]
