How high are people spinning these transmissions? Would they survive behind a BMW S54 going 8200 RPM?
All the info I can find from ZF says the highest production engine goes 7200 RPM in front of them, but I don't see a number that ZF says is the max RPM of these transmissions.

Re: 8HP RPM Limit
I setup 8k rpm. My car is daily but hit 8k almost every day
Five months and no issues.

Fantastic, that is what I was hoping for!
