Converter stall question I just installed a 2800 stall I got from a guy that does converters and trannys. When I put the brake to the floor and hit the gas, the tires start spinning at anywhere from 1900-2200, which is amazingly a huge difference compared to stock (1600). I don't think that 2800 stall speed is right, question him about it through middle men, and he claims it's made for a 500 HP application. So when I'm stalled at (let's say) 2100 on the line and then I let go of the brake and put the gas to the floor with nitrous, it will stall up to 2800 before taking off. I know that is probably confusing, but I think this guy is full of ****. I have never heard of a converter working like that. I've heard of converters stalling higher than their stall speeds with a lot of power behind them, but never a converter that needed the extra power to actually get to it's specified stall.
What do you guys think? I don't know much about converters.

You can never brake stall a converter to its true stall in a typical street car. You just over power the brakes. If you have second gear start you can use that. You'll get closer to true stall, but still not there.

The stall speed is basically measured by "flash stall"! This is where you mash it from idle and the TC will "flash" to 2800+ immediatly.
I have a 2800 in my car I can't brake hold it with Hoosier QTP's much more that 1500 before it starts pushing. I now flash it from the line. Much better performance.
Flash it and watch your tach it will hit no less than 2800. if you hit it with N2O it will flash even higher.

Converters will stall at different rates based upon the power your making. But as mentioned above, brake stall does not equal rated stall speed and all converters stall higher when you apply nitrous. If you had a transbrake you'd see what the stall is on motor. The guy was right about it flashing to it's stall after you foot brake the car. What you're seeing is the result of the brakes not holding the power.
