Has anyone ever nailed down driveline loss?
I was wondering if anyone has gotten a hold of what kind of driveline loss percentage different combos. cause. I ask as I am going with a t56 and 9 inch and was wondering if anyone has done an engine dyno to chassis dyno comparison of that, or anything else that one can empirically figure it from?
Thanks in advance.

There is no 'nailing it down', as it will change from chassis to chassis, tranny to tranny, rear end to rear end, wheel to wheel, converter to converter, etc.
You could pick up rwhp going from a 12 bolt to a 10 bolt, from 20" rims to 17's, and from a glide to a t56 without touching the engine...

The motor made 650 on an engine dyno with a carb only running up to 6000 rpm. It then made the number in the sig through a 90/90 and 85mm maf. As I said the clutch was a ls7, 3" steel driveshaft and the 9" with a 370 gear. No tricks with the motor, Evans water pump and an ATI dampner with 10% reduction

I don't know about other dynos but the dynojet 224x has a negative horsepower run option where it measures how long the drum takes to decelerate with the clutch pushed in or the trans in neutral. That would tell you exactly how much power a particular setup looses. my $.02
