It's not hard.
Peak torque is always before peak power.
A clutch will start slipping (if it slips at all) just before peak torque, well before peak power.
Peak torque is normally anywhere from 3000 to 6000 rpm , depending on the motor & mods. A motor with peak torque at 3000 might have peak power at 5500, a motor with peak torque at 6000 might have peak power at 7000 or higher.
As for your previous post, I think you just made it up.
So , if a supplier starts talking POWER, go somewhere else.
