How Many Horses does your Posi eat?

I seen a test on I think it was hot rod TV. The difference between a small Chevy 8.5 and a huge 12 inch DANA was 5 HP with the dana eating up IIRC 15 HP to turn preety fast.

Don't beileve that hype of big rears eating up a ton of power. Also there weight difference is a moot issue since there bigger and (Key word coming up) STRONGER so you won't have to replace parts with cubic money bills that could be served else where better.
