Guys,
Finally at around 140K my clutch has had enough. Noticed in S# it is slipping heaps once boost kicks in, basically free revs. No noises, just revving more than accelerating.
I have just read a number of threads talking about brands, SM versus DM and HD versus standard.
What do people recommend as the best option given the car has some mods and probably sitting around 180atw. I find the clutch a bit light and high for my liking but don't want a massive change that i will regret as i do sit in traffic a fair bit these days. In saying that I want it to grab hard and fast when I want to.
So from my reading so far the pros and cons of Dual Mass Flywheel (DMF) versus Single Mass Flywheel (SMF) are as follows:
DMF
Pros: No/Minimal NVH due to inherent dampening design, less stress on gearbox and driveline components, smoother acceleration (less rattle under load conditions).
Cons: Cannot be serviced/machined, more prone to overheating, can do more damage when it fails, more expensive to replace, less/no compatibility with HD clutches
SMF
Pros: Can handle more heat so better for performance applications, can be serviced/machined, cheaper, potentially more reliable (solid steel versus layered with spring(s) etc), compatible with HD clutches
Cons: NVH/rattle through drivetrain due to engine pulsing (otherwise absorbed via DMF)
Guys what I am really looking for is feedback on how much NVH difference did you notice. Apparently this can vary a lot between vehicles in general and SMF kits from one to the next. I have read that you need to alter your driving style due to NVH when engine is labouring so you need to change gear later etc. Also interested in what combination you are running (e.g. SMF with Standard Clutch versus, DMF with HD Clutch etc).
Cheers,
