Shawn Ellerton's 6.0 made 1,004 horsepower on the dyno, but his fastest 1/4 mile time is 11.32 @ 122 mph. You would think he would atleast be in the high 10's with that kind of horsepower...

I just think this dyno pull was legit and not reading high. There were no spikes in the curve. Hell, maybe he could have made more horsepower if the operator hadn't let out of it so quick. You can see on the curve when he let off of the throttle. It was already dropping power in the curve before he let off
yep

Our race truck dyno'd 1060 on fuel, but now at 140MPH and confirmed 6100lbs, we are at 1135HP. MPH vs weight = HP does not lie.
yep

sticker on dorr is 9600 GVWR, not unloaded weight.

subtract gvwr from your max bed capacity and you get your unloaded truck weight.

Fords are quite a bit heavier than the Dmax.

The HP calculator is on compD and has proven to be accurate for diesel trucks.
Horsepower Calculator, calculate hp from et, trap speed, calculate tire diameter, mph and rear end ratio.
Rob are you saying i'm fat?

all the scales i ran across was with me in it and a over half a tank of fuel and most every time i weighed right at 7500lbs if not a lil over! thats with the LBZ in my sig!
