2 questions for the experts.
#1 Does the power range of the engine (cam rpm characteristics) have a lot to do with the stall rpm?
#2 Is the final drive ratio and highway cruise rpm also important?
Yes and Yes.
To give you an idea how different our S800T is to a stock converter (it's my first)
It flash stalls to about 4100/4200 RPM. The trans is programmed to shift at 5K RPM.
When it hits about 4100 RPM in high gear the RPM stays Steady and the speed continues to rise!!
If you floor it at interstate speeds it jumps up to stall so fast it feels like it downshifted, but it didn't.
Truly amazing and well worth the extra $$$
Now if the track would just open!!!
