Is it usual for a clutch to start slipping after two years use? I fitted a new 16v clutch to my motor (2.0l 16v) while rebuildingmy car two years ago, I havent done loadsa miles and I dont thrash the pants off it. My motor is mildly tuned, polished ported head, stainless manifiold KR cams and thats as far as it goes, I would suggest its only around 150bhp (not been on a dyno). How many horses can a standard 16v clutch take, what options have I to upgrade?
Mk2 16v? Have you checked the cable? As the clutch wears, the cable will go tighter. If you don't adjust it the clutch can slip. A good standard clutch should be fine in your car, although it should be nearer 170bhp, at that spec. I used to run a Sachs Power clutch (see GSF and others) in a similar spec of car. It was fine too.
Only put a new self adjusting cable on it a couple of months ago, do they sometimes not "self adjust". I did notice that the arm/lever into the box doesnt return full down as though the spring inside is faulty , could that cause problems?
