i think you lose hp on a dyno with a stall

Doesn't effect HP at all, just enables the truck to stay in a certain power band longer.

you would think because less weight on the rorating assembly would increase in hp or throttle response!!

yes, a little maybe but the largest gain comes from getting right into the power-band of your engine and staying there after each shift.

i should have explained better
its common to get lower readings on a dyno with a higher stall vs stock stall.
the actual hp doesnt change,just the way its transmitted through the drivetrain

Yes, I would agree with this. The stock converter weighs in @ about 54lbs. My 9.5" converter weighs in @ 23lbs empty and when I primed the converter, I reweighed it and came to about 29lbs. However, if I had reprimed my stock converter with fluid, then I might be looking @ 58lbs or almost 60lbs. Cutting the converter weight basically in half would net you some HP gains. I know I felt it in the bott-o-meter........the truck would rpm faster from offline to redline. What were some people saying about rotating mass with wheel and tire combos...........it's like 5x or 7x of the actual weight of an object when you try to rotate it.......It takes a lot more energy to rotate something versus just picking up the object. I tried shaving weight on every little thing just to free up the hp and tq. Just remember, the more you can shave on rotating weight(no matter what it is), the more "free" hp you'll gain.

Just my .02's..........

Good points! How much of that additional weight on the stock verter is from the actual housing or stator blade compared to how much is from the actual rotating disk or blade?

I think it's more on the housing than anything.......the billet front hub, smaller internals..........I'm not sure on the inner workings of the converter. I just know that when you loose some of the rotating mass, your truck will get faster on the big end, more power on the dyno and laungh harder out of the hole.
