well i have a formula i use to get rear wheel hp.... it is as follows
hp=weight*200/et*et*et
hp=2750*200/8.962*8.962*8.962
hp=550000/719.8
hp=764
i went to tim mccamis like you said and used the calculator. it says that i have
755.1 rwhp and 981.63 at the flywheel.
i just have a hard time believing this pooch of mine make almost 1000hp... i also have a hard time believing i lose 230 horse to the tires....
i have used my formula on a buddies dragster that makes 900 hp on the dyno and he had 900 horse at the rear wheels on his best pass....so thats why i wanted some input. making 1.512 horse per cube is respectable outta a 505 with box stock heads and intake.
i don't believe that you lose 25% to the tires. i understand it takes hp to initially turn the drive train but everything you put into the rear gears, converter, and trans is multiplied to the tires. granted you lose some through converter slippage, but 25%???
once you get the mass moving in stays moving (newtons law)....
anyone have any thoughts on this???
