So after doing some research last night I will agree that the weight of his truck is what is hurting him. His truck's weight is around 5500lbs (closer to 5700lbs with him in it), so I guess it makes sence now that eventhough his truck has about the same amount of hp at the wheels as you guys have total, his truck is a tenth behind yours.

That being said though, I still want to see more than 1 dyno result, and more than one track time from someone other than v8440 though. Every site I have checked so far only has v8440's times and dyno numbers listed and no one elses which makes finding compairable results really hard....

 

There is one other guy somewhere that dynoed his stock '09, and he got 322 hp. That is much more realistic when you consider weight and trap speed. Like I've said before, the dyno I ran mine on is pessimistic to the point of impossibility. It's really only good for a ballpark estimate or for comparisons against previous pulls on the same dyno.

The same dyno said my dually only made 450 hp, yet it has run 98 mph in the 1/4 at 7000 lbs. Plug those numbers into a calculator that uses weight and trap speed and see what you get.
