    What is the stall speed for a factory torque converter? If I remember right it is 1800-2000 RPM isn't it? (700R-4)
    Thanks

    I think its even lower than that, I bought a 1600-1800rpm converter and I was told it was about 200rpm above stock. It also depends on the vehicle, trucks fitted with Th700's have lower stall speeds than cars fitted with Th700's. If you give TCI or B&M a call they'll be able to give you accurate figures...

    I know this is a stupid quesion but I really dont know much about TQ converters what would the advantage be to get a higher RPM one? like if you had a modified motor and so you stay around the RPMS of your enging? and is TCI and B&M on the same page for tranny stuff?

    the TQ converter stall speed should match your motor's power level.. race car drivers want a higher stall cause they dont want to "move" till there motor is making the most power.. or a big amount... imaging pulling up to a stoplight and giving your truck gass till it hit 3000..... and then the tq converter allowed teh tranny to use that power.... almost like a clutch... the tq converter allows the tranny to "slip" untill there is "stall speed" provided by the motor... so the converter allows the motor to build up rpm and power untill the motor reaches it's tq's stall speed...

    Kinda like dumping the clutch at 3000 rpm's... hehe
