zetec-type9 clutch limits?
i went down the well trodden route of the early Mondeo clutch and pressure plate on 1800 zetec flywheel with long capri release bearing
now after 8000 miles driving and lots of racing standing starts and tyre warming from hill-climbing, sprints, auto-test and 165bhp_135lb/ft (now more)
on a tall 1st ratio kit, semi slicks and a LSD I'm starting to get on occasion the clutch will tend to not instantly bite for half a second and
a bit of a whiff on a hard standing starts if the tyres dont spin up, looking back at my dyno sheet on the unported head i was making 110-115 lb/ft at
3000
I'm begin to think I'm getting to the max of the spec of the clutch and pressure plate I'm using as it seem fine on the move.
its was reasonable quality clutch kit (LUK) and I'm now thinking it might need an uprating in the near future?
anybody had any similar issues or know of any reasonable upgrades without going too mad? i do have a spare flywheel but ideally don't want to go
down the faf of re-drilling and balancing to as it would probably be cheaper and easier to swap out the flywheel at the same time to a lighter option?

No issues with an 1800 flywheel but redrilled with Pinto clutch. On st170 engine, in a spitfire so heavier and shown little mercy. Done at least 15K
now including a few runs at Santa Pod (they are hard on a car)
I assume the clutch does not need adjustment (ie there is still free play)
