    Stall speed is the point where a converter has reached it’s maximum fluid flow or it has hydraulically locked up because torque multiplication has reached it’s highest point.
    All stall speed ratios are approximate and will vary, based on the torque of the engine. Stall speed is the amount of engine R.P.M. that can be attained at full throttle with the brakes locked and the transmission in gear before the drive wheels turn. Attainable stall ratio are often not exceed due to the vehicle braking system, which is even worse with disc brake equipped cars.

    Thanks for the help. This would basically only be used for racing off the line right? So from what I understand is so that your engine would take off faster rather than opposed to a dead stop right?

    Could be about .5 in the 1/4 mile
    It can also extend your shift points.
