That is a good question and one that is tossed around quite a bit in several forms of racing. I have never seen a chassis dyno test between a standard rear end and a quick change. My guess is somewhere between 5 to 15 horsepower loss from a 9" Ford to a quick change, however I have heard people estimating 25 to 40 horsepower loss.

how much horsepower/torque is this rear rated for? Am looking for a good rear for a 1930 model A hot rod build, running a blown hemi rated at approx. 550hp.

Winters does not give a specific horsepower or torque rating to their rear ends but we have customers around the world that have far in excess of 500 horsepower using these rear ends without problems.

2.5" offset You list a 2.5" offset to the axles. Does this mean that the center section and drive shaft would NOT in the center of the axle? If so, why???

No the pinion is centered in this rear end. The 2 1/2" axle offset refers to the distance from the end of the axle tube flange to the axle face where the wheel bolts on.

Is the 56" dimension from outside axle face to axle face or from the brake flange surfaces? I thinking of running this in a 1936 Ford coupe with a T5 5 speed and parallel leaf springs. I noticed you have a drum brake application for the 2.5" axle offset value but don't see a disc kit for 2.5" offset. Any ideas?

On the Winters rear ends number 8022550 Speedway offers a bolt on disc brake kit number 91031902 or 91031921 and also weld on kits if so desired. We also offer Wilwood kits with or without E brakes under number 8351402118 or 8351407140. This rear is 56" wide from axle flange to axle flange.
