I am curious about this:
using:3- shoe clutch setup,with standard weight aluminum shoes
With the thought of clutch spring rating/engagement(highter number=thicker spring=later engagement=more snap),and the dyno numbers an engine data archive.It seems as if a lot of engines make their peak hp and trq at a lower rpm than the engines peak rpm.Does this mean you need to tune your clutch springs to engage at an earlier rpm rather than at a later rpm(lower number clutch springs),so you are in that lower peak hp/trq rpm area?
I understand grip also comes into play,but mainly curious about this aspect of the tuning.
Any help would be greatly appreciated.Thank you.
