This is better Scawen.
As for the way you calculate the clutch strength.
It should be a combination of power and engine inertia
If we have two engines with the same power curve, the one which has more inertia doesn’t necessarily need a stronger clutch.
It all depends in the given time both engines how much energy they can store in rotational inertia.
Eg while been airborne after a bump for about half a second, at that given time in which the engines just increase revs, the one with the heavier inertia will just reach lower revs comparing with the lighter.
Unless the engine with the lighter interia hit the rev limiter and stop storing energy in rotational force, both engines are going to store the same amount of energy and the stress on the clutch will be the same when the car lands again.
If the lighter engine hit the rev limiter in that given time, the one with the heavier inertia will store more energy and stress more the clutch so in that case the “heavier” one indeed need’s a stronger clutch.
A simple example.
Let’s say that XRG’s engine inertia is able to store twice as much energy in rotational force while been at 7000rpm comparing to what the XFG can store in 7000rpm.
This doesn’t mean that the XRG needs twice the clutch strength to hold that maximum inertia force.
Because in a given short time (that half second while the car flies over those big bumps in rallyX) XRG’s engine is not that more powerful over XFG’s, to store twice the engine’s rotational inertia force.
I am saying that, because still the XRG’s clutch seems to last way longer in the same conditions comparing to XFG’s as
JTbo mentioned.
Anyway I think there is not anything else you can do now, patch Y is coming soon and the clutch is much more usable now in some cars which had problems.
Just promise us that you are going to work it again in the future, with some real data because now I think it is pretty much guess work
