DO higher numerical #'s skew Dyno #'s?

What a can of worms...

Theoretically it SHOULD...given that the dyno is measuring acceleration and the gear ratio difference is a difference in torque multiplecation, therefore acceleration SHOULD be different, changing the numbers...now figure in different tire sizes and..........

just my. $0.02

And none of the info is "skewed" really...it IS what THAT truck is laying down!!
 
in high hp (dyno queen) trucks, a taller gear is desired to help load the engine better and achieve higher boost numbers.
 
Ive dynoed a truck that went from 4.10 to 3.55 within 12hrs. it made like 5 to 10 hp more. I think the tires were 33s.

I agree. gears have an affect as well as changes in tire size.
 
Like it was already said I think the gear will either help or hurt the charger in making its power. The gears arent going to add much if any power themselves but improve the scenario for the truck to make more boost and power. But what works on the dyno isnt always whats best for racing or sled pulling so it shouldnt be a concern unless the truck is just a dyno queen.
