How does the Weight change the Dyno results

How does the Weight change the Dyno results? If one 05 GT dyno's on a Mustang Dyno with a weight of 3450lbs. and then you change the weight to 3650lbs and make another pull, what would the differnce be in the no.s?

Don't know....I'd be curious to see exactly what it would be. But seeing how the dyno loads the car as to how heavy it is and applies that to the resistance of the drums when the car tries to spin them...the heavier the car the harder it would be to spin....or at least I'm taking a guess here that is how they designed it to work. I wouldn't think a 2000lb Import would have the same rolling resistance as a 5000lb Impala convertible.

Find someone with a Mustang Dyno near by and try it out..go from 3000lbs to 4000lbs

the weigh is loaded into the dyno before the run. weight won't make a difference on the dyno numbers

So the dyno is run on the same weight no matter what the car....just figured as a constant?

no the dyno computer ask for the weight to be input. (dynojet)

weight wont affect how much horsepower the car makes. it will just make the car accelerate slower/handle worse.
