Finally got on a Dyno

Got to put my truck on a Dyno today, not too bad of a run, HP was 435, really thought it'd be in the 500 range; Torque was 894, I expected that. I'm happy with the numbers, I at least know what my truck can do now. Next step is the 1/4 mile time.

I do feel with my mods that I should've at least been in the upper 400's if not 500, or am I dreaming? I have to find a shop in my area that does it, and not just a mobile machine.

you were well over five at the crank... you're going to lose a good 20~25% through the drivetrain...

don't get worked up over horsepower.. it doesn't mean a dang thing, though we want it to.. torque is where it's at... those twisties are what makes horsepower, and what mr. dyno operator actually measures before starting calculations to derive HP from..

most folks know this, I know- but not a lot of folks think about it in this way:

torque is spinning power.. horsepower is rate of work.. if you're making 500#sq.inch of torque, that's how much grip you'd have to have on the crank to stop it from spinning.. if you slap a wheel on the crank, and attach a rope- how fast you can snatch a predetermined amount of weight off the ground is the rate of work- or horsepower..

these things puke torque.. the ratio is out of whack in favor of torque, because torque is what they are designed for.. all engines are, but the gearing and the very nature of compressed burn on these makes use of torque instead of gearing it out to HP by the design of the OEM..

if you're more interested in making HP, then make use of all that torque you've got laying around... use a higher ratio (numerically lower) at the diff... use taller tires.. both effectively increase your overall drive ratio, take more torque to operate, but do more work quicker (aka HP).. realize, though, that cutting into the torque you're not using will make the truck lose momentum easier, and hunt for gears a lot more.

Well just talked to the guys that did the tuning, they said they doubt my truck was that low, they said their tune is guaranteed for 500hp or better at the rear. They said they think the dyno was the issue, said there is a great margin of error with portable dynos.
