Can't comment on the 9" but I would imagine around 30hp+. Also don't forget that you are probably driving accessories now that weren't on the dyno...power steering, fan, alternator etc etc .... add in enertia and drag of the driveshaft, uni joints, axles and bearings, rolling resistance of tires etc... It all adds up pretty quick !!

Do the math. If the 9" really is 30HP then look at the torque input at 6500 RPM

HP = TQ * RPM / 5252 so imagine you're in D or 4th (1:1 with the engine) and you're at 6500.

The TQ would have to be 24 lb-ft. Something would have to be dead-wrong in the rear. Mine reads (with drums installed) under 5 lb ft which would extrapolate down to ~4HP at 6500.
