Clutch -- Half/Full Clutch

Recommended Posts

Hey

 

I have a carbonetics Twin plate or triple carbon clutch, I was reading the artical (http://www.carbonetic.net/tech/pdfs/CClutch_Universal.pdf)

 

 

What is

 

  1. Avoid a Long Half clutch
  2. For an extented Life of the clutch, try and use as little half clutch as possible? preferably 0.5 Seconds
  3. What is short shifting?
  4. Is it normal for an after market clutch to have no cover to speak, I know the carbon ones generate alot of heat but my clutch has a large enough window in the side of the casing for dirt and crap to get in at it, I presume this is for heat disapation? Was think of putting a gromet over it , its approx 8cm by 5 cm

1 and 2 refer to slipping the clutch. 3 is changing up before max rpm.

 

That clutch looks like a primadonna pain in the ass, it's got more caveats than a R35 GTR warranty.

I never seen instrucutions with so many caveats :),I love the warranty and the 100 reasons on why you have void the warranty

 

Dont mean to sound like a dumb ass but what do you mean by 1 and 2 refer to slipping the clutch ?

Erm, well, er, you know, when you bring the clutch up and it's not fully engaged but it is moving the car, like every time you pull away or you'll stall it? And for a fast getaway you'll get the revs up and then use the clutch to control the transfer of power to the wheels? That's slipping the clutch :)

 

It's called that because the friction material of the clutch is rubbing against the flywheel, but isn't pushing hard enough against it to spin at the same speed as the flywheel. So it slips, thus controlling the amount of power being transmitted to the gearbox and therefore wheels. This generates heat and promotes wear, hence the caveats to not do it much.

 

A sympathetically used clutch can last for years, as it's really only the slip that wears them down.
