Dynamometer Results & Comparisons - New Numbers with 9" rear

Well, the car could be sold Sunday, but while I had the chance, I had it dyno'd one last time with the 9" under it. Through the 9" with a 4.10 gear, the car put down 453 rwhp and 404 lbft of torque. The only changes were the 9" rear, and I finally changed the brake calipers. I know one of my old rear ones was dragging some, but I didnt think it would have been bad, until I saw these numbers. These were on a DynoJet at Bluecat's in Burnough, KY. What is funny, is that this particular dynojet, seems to read a little lower than others, and on other peoples cars, has read less than the SuperFlow we were using in Lexington, KY.

so 13 rwhp lost? sounds about right compared to a stock 10 bolt

What I mean is one of my friends cars that should dyno in the 430's or 440's, only dyno'd 404 on the dynojet I used the other day. It reads a little lower than other dynojets, which is probably more realistic, but still lower. I wonder what the car would dyno back on the SuperFlow dyno that I got 465hp on before? I beleive one of my old rear brake calipers was dragging and prevented me from dynoing a little higher at the time I did 465hp. I would expect a 9" to rob more than just 12 horsepower.
