[QUOTE="bigrig, post: 1408980, member: 11383"] The way I understand it is the only time weight that matters on the dyno is the weight of the rotating mass in your drivetrain (including the wheels). The heavier these parts are, the more parasitic loss you will experience from the engine and the less power you put to the ground. Another way to look at it is if you stripped your vehicle down so it weighed 1000 lbs; Would your truck's engine make any more power? No. Would the truck be faster in the 1/4 mile in the real world? Yes. The dyno is just recording the engine's output while it isn't under load. I think the process of entering the curb weight into the dyno is to simulate what the real world results will be, but that metric is different than what power the engine is putting out while it isn't under load. Take this explanation with a grain of salt, I have never dyno'd any of my vehicles. [/QUOTE]
