    will only stall to 3000 if youve got a trans brake to see if it is a 3000 stall floor it in a strait line and watch your tacho and see when it takes off

    What is stall speed and how do I determine what stall I have now?
    Stall speed is a term used to describe the rpm at which the torque converter transfers the power from the engine to the transmission. There are different ways to test stall speed. "Foot brake stall" is when you press the brake pedal and then press the gas pedal. When the engine rpm doesn't go any higher or the tires start to spin that is "brake stall". (DO NOT TRY THIS! THIS MEASUREMENT IS MEANINGLESS AND POTENTIALLY DANGEROUS TO YOU, THE TRANSMISSION AND THE TORQUE CONVERTER!) "Flash stall" is when you, from a dead stop, press the gas pedal to wide open throttle (wot). Watch your tach needle, you will see the needle jump to a certain rpm, that is "flash stall". A drag racing-style trans brake will give you closer to the true stall speed of a torque converter.

    the stall rpm is the rpm at which the converter will be turning the input shaft at engine revs with no slip so yeah you will do burnouts before than ide say

    2000 before it turns the wheels is heaps above stock, mine turns the tyres at exactly 1300 rpm while on the brake, it's rubbish :D I'd be pretty happy with 2000, it should be able to flash higher than 2000 from standstill depending on how much grunt you have

    Problem solved, took it back 2 the auto place cos i just couldn't get it 2 stall any higher than 1800, the guy took it 4 a test drive n said yea its way 2 tight and yea not much different from standard, he couldnt get it past 1800 either even flash stalling it, he said standing on the breaks i should b able 2 get 2 at least 2700 so he's sending the stall bak off 2 b loosened right up, he said that every stall is different and sumtimes it takes them a couple of goes 2 get an idea of how loose it needs 2 b. so yea problem solvered :w00t:

    yea which is normal for a 3000rpm stall, cos 2 get it up hard against 3000 ya need a strong motor, which i can understand.
