I run a full 35 degrees not timing backed out, I have to leave at idle and slowly roll into it. I tried hitting it hard yesterday but it just spins, so its more like a controlled acceleration. One thing some of the racers said yesterday was that my converter never seemed like it was locking up. Its my old 10 turbo action converter, which they said might be getting too loose. I have never checked the stall but if you are rolling along at idle and hit it sorta hard, my tach goes to about 3800 before the car starts to accelerate. I really dont know that much about that stuff.
