After 3k miles on my new clutch and lightweight flywheel I have begun suffering some slippage.
This first happened few weeks and a couple hundred miles ago when I went for a spirited drive and then the car was sat running for 20 minutes or so, as I drove off anything over 2.5k revs would slip. A few minutes later and it was fine. Next day I tried the clutch test by flooring it at low speed in high gear and no problems at all.
This weekend the problem reappeared when I stopped at motorway services on a hot day and when I set off same problem occurred.
It would appear to me as though something is overheating when stationary and once I get some air running through all is fine.
Has anyone experienced something similar or know what this could be?
