Torque converter Stall?

[RedZMonte]

So i have looked around and saw a few different stock stalls on the 4T60-e. The car is a 3.4L DOHC, the highest stall listed was the 2095 (IIRC)... Getting a custom one made, with my turbo setup i was thinking going like 2500 sounded like a nice number... what do you guys think, Too low? the car is my DD so i don't want to go to crazy but i do want the stall a little higher...

correct me if i'm wrong, but most turbo engines like a lower stall to help load the engine more...

i'm not sure how the powerband of the LQ1 (let alone a turbo'd one) will effect that though...

I think the higher stall will allow the turbo to spool up faster... i know the Turbo L36/67 guys run normally ~3000 stall converter..

Does anyone know the stock stall speeds?

You can get a good approximation by first warming the car up, then lock the brakes down tight and with the vehicle in low gear gently step on the gas pedal all the way to the floor. The reason for stepping gently on the go go is that you want to be in control in case the vehicle tries to move or the tires attempt to spin. Take note of the tachometer, or engine RPM parameter on a scanner once the engine ceases to rev any higher. This will be the effective stall of your converter. Remember also, that as you increase power input to the converter (engine mods, bolt ons, etc.) the stall factor will increase as well.
