Torque control with logger vtech
Is there any way to measure torque with Vtech datalogger?

No, you would need an engine dyno for that
For a description of what parameters the V-Tech logger will log as well as some video's explaining the system please click here

I think it is a fundamental parameter to not break the clutch pwc.
I understand that I need to test.

This must be checked with a torque wrench.
Best way is to remove the supercharger from the ski. Use a gear holding tool to hold the gear still. See tool here
Then use an accurate dial type or digital torque wrench and turn the impeller nut counter clockwise to measure the point at which the clutch slips.
Ideally you want 1 ft lb slip moment for every 1 psi boost anticipated. This means, if your supercharger produces 16 psi boost pressure then you want 16 ft lbs slip moment.
I like to set the initial slip higher because the washers will settle in and have a lower reading after some time. So in this case, set slip at 18 ft lbs and after a couple hours of riding the ski the slip will settle around 16 ft lbs.
Hope that helps!
