Th400 clutch question

[kwkracing]

At about what hp/weight does the intermediate clutches need to be changed from the 3 clutch to 4 clutch set up?

It is a reverse transbrake th400

It more important to have the bigger sprag than the extra clutch but both is better at at any hp when your beating on it

Thanks for the advise, but that is not what i was asking about. I want to know about what power level you need to worry about adding more than 3 intermediate clutches to hold or if there is really even a reason to add 4 in that pack. Thanks
