Thread: Torque Convertor

Tweet

I'm installing a 383/460 hp I've got a 700r4 and been told I need a 2500 stall but what i found so far is 2300 to 2500 or 2400 to 2800 witch way should I go here

make a phone call to who ever convertor your going to use .there is many thing s that come in to play with the stall you may see. gear . tire size . weight of car size of cam .cfm . TQ

Thanks, didn't know it took all that

yes if you want it right it will

You're seeing a range of rpm's because the converter mfg has no idea what the torque of your motor is at the flywheel. If it was, for instance, 400 ft/lbs, then it might stall the converter at 2500. But if the motor produced, for instance, 475 ft/lbs, then it might stall the same converter to 2800. More torque, more stall.

Don't hold me to these specific numbers, I'm just trying to help you understand converters and stall speed. Like Pat said, there's more to it than meets the eye.

Thanks again for the info I called Hughes they wanted all the info from the engine to the rear 2500 was bare mininum they said 3000 stall would be the best of both worlds.
