The cover plate is an aluminium Sach and the flywheel a very lightweight unit from Chris at Fenn Lane some years back. I am experiencing sometime a small degree of clutch engagement slip going from full WOT in 2nd to 3rd uphill.
Bite off the start line is good, (1G) and no slip from WOT 1st to 2nd. when 2nd is engaged the revs are about 4500 when 2nd is engages. I change gear around 7000 rpm.
There seems to be little choice available. I don't want to change the whole clutch to (say) a twin/tripple plate with solid centre, I feel the road spec friction plate cushions the very harsh changes a bit.
Is the road spec Sache clutch man enough for this engine/ application?
I think there is a Heavy duty centre plate on Design911 but that is rated at 350 Nm ( 260lbft).
Not sure about Helix road going driven plate, so thought i would ask on here first.
The car weighs 560Kg but has the stickiest slicks too, hence 1G acceleration from standstill.
I need to preserve the flywheel from slippage damage.
