Clutch LSD..Settings value welcome

[Stephane Goria]

Hello,

I am making 2 clutch type LSD to fit on my GT40 and one my friend's GT.

Both car have an average of 300 hp with an average of 350 ft/lbs torque and 1000/1100 kg weight.

The lsd we gonna install is one of our own, I mean a permanent friction type with no progressive value. So basically preload is the working value of the permanent friction.

Any recommandation for a good torque value making the car not to go understeering and in the same time keeping it straight...?

settings of aperfect world basically..

Greetings

Stephane

Generally most tarmac rally car with plate diffs run somewhere from 25lb to 60lb of preload (after bedding in, so probably 35lb-80lb initially).
Obviously they have acceleration ramps to help though, so I would think you're just going to have to start around there and then raise it until you get a good balance between traction and handling.
