I'm wondering what other GM cars have torque converters that the 700r4 can use to get some gains in acceleration and 1/4 times. I've read that C4 vettes have a nice 2500? stall and that S10 trucks have a nice 2200 stall. Is this correct?

What would be a downfall of installing one of these? Will the gains be worth it?

 

i've used the stock converter off a 1998 S10 with the 4.3L it was a 2200 stall, I believe the corvette ones are the same, although the S10 one is cheaper than the corvette ones, probably for the name alone. There's no downfalls for a 1000 extra stall speed for $140 with lifetime warranty from autozone, give them your stock one as a core too.

 

I've got a 1991 GTA, is my tranny a 700r4? I'm interested in changing my stall converter as well. Although, I'm leary of Autozone parts.

 

Thanks for the info Xpndbl, did you notice a nice gain from them, sotp and 1/4? How did you launching get affected?

Thanks again.

yea definately launched a lot harder with that extra stall, was worth .3 in quarter mile times but then again the car was in the 14s at that time.

 

What were your 60fts like before and after, or are you a pretty decent launcher? Did it improve mph too?

 

i had that converter in the car years ago, i don't remember the times. New combo is a decent launcher though

 

hey i've heard different things about torque converters i was hopin yall could help me out with. both are auto techs.. one says if your converter has a 2200 rpm stall the car wont move until it meets that and the other says its what the motor will stall out at (or not rev higher) unless the car is moving. and if thats right which makes alot more sense, would there be an advantage if i can spin the tires at a stop with my 215 tires?

 

Although both ideas in prinicple interpret what a torque converter does, the effect of the operation of a torque convertor in practical application will not cause the engine to stall or the car not to move "at all" until the stall rpm is reached

It just simply means that the EFFECTIVE engagement of the torque convertor is complete by the engine rpm increasing to the rated stall speeed of the convertor

So, a slightly larger cam that needs to be slightly higher in rpm before delivering full potential to the engine output will be complemented by a higher stall convertor which = both engine and convertor will reach their peak potential at the elevated rpm and the energy will be transferred to the momentum of the car

whew!!!!
Tech guys - feel free to chime in if this isnt as clear as is should be

 

is there any 60 degree v6 torque converters that have a higher stall then my firebirds?
