I was in the converter business for about 7 years, an 8" converter could actually be an 8 3/4 turbine ID. Depending on your stator, your power and shifting rpm it's easy for those little guys to slip. A 6500rpm shift is not a great window for them under high power to really couple at peak.
But on a car that shifted at 8500+ and was a 4.42 AWD these would be killer up top even at 800hp. The 9" could be the 9 1/4" ID turbine and depending again on stator, power and shift rpm you might see a big drop in slippage. Thick John Deere fluid can easily tighten a couple % or more depending on total slippage.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
