TF904 Torque Converter selection

For racing you want a convertor that stalls at 500rpm above the rpm your engine makes peak torque.

One the street it's a compromise. Dynamic told me they like to set the stall at peak torque for street applications if possible.

I don't really know where the limit is for street driveability. i've run a true 3500 and a true 3900 stall convertor on the street with no issues and under normal driving you could not tell there was anythign other than a stock convertor in there.
