am i correct? i've always wondered how a converter with a higher stall speed improved the performance of the car. so i been doing a little research and this is what i've concluded. am i right? or am i missing something?
stall occurs when there is not quite enough fluid in the torque converter for the impeller to move the turbine (which in turn, turns the input shaft). a torque converter with a greater stall must have larger openings in the impeller and turbine (forgot the techinical name for those openings). therefore, this allows for greater pressure to build up inside the converter and as a result, will turn the transmission input shaft faster. resulting in greater acceleration.

Can't comment on the inner workings, but think of it as an automatic clutch.
You understand how launching at a higher RPM is useful, so its not much different in that respect.
How it IS different though, is a clutch doesn't do torque multiplication, or increase your shift extension (RPM after upshift) like a good torque converter.
