I was just wondering if anybody knows the "stall range" of the stock converters in our cars. I'm going to get a TCI one before the end of the year and am thinking about a 2500rpm stall one. would this be to high for going down the highway at like 2100rpm? is the stall only in first gear or all of em? thanks

 

I got the same car as u, only stock for now. But i would like to know whats the stock converter at too? I think ive heard low 2000s, but i'm guessing. If id uprade id get like 3000+

 

man your car is perfect man. mine isn't near as nice as yours. mine has been vandalized 4 times though, and they hit all the major focal points too. oh well, I dont think thestall converter is at 2000 though, I would guess like 1300 or so. just a guess through from racing. and I have a car w/ a 2500rpm stall converter and you can "feel" when it locks up. so thats why I say 1300rpm. but I"m jsut guessing

 

Stall rating depends on how much torque is put into the converter. The same converter will stall at different speeds behind different engines.

Typical stall speed of a factory converter is 1200-1500 rpm

 

Then i was way off..lol 1300 is low, damn factory. Thanks 87transam, but that sucks about yours, life does some **** to us somtimes, oh well. So 2500-3000 would still be good to get.

 

If your GTA is stock, that is WAY TOO MUCH CONVERTER. Stock tpi engines quit pulling somewhere around 4500/4700. Even lightly modded like mine is done at 5500/5600. I just took out a 2200 stall that flashed around 2600 or so, and went to a stock 4.3 astro van converter. Haven't had it to the track yet, but it sure feels better.

 

hey hey!! I have a astro van converter sitting around. maybe I should try swapping that baby in, is it a smaller converter that is stalls higher or what?

 

I think alot of it depends on your rear end ratio and cam. At least when I bought my 9.5" ACT 2400rpm TC from Dana at Probuilt thats what he asked along with a few other things. My engine is a 5.7L stock with 3.42 rear ratio. It takes a little more pedal to get going over stock, but once you punch it it really wakes up everything. As far as highway driving, you wont loose any gas mileage once the TCC locks.
