Hi all

Thanks for the great feedback on my previous thread about clutches.

Just got one last thing on my mind right now.

What is the differences between the different amount of pucks on the single plates ? Ok I know the physical differences as Ive seen them for myself....just wanna know the theoretical applications.

Say theoretically, with all things equal. The following clutches were installed on the same car with same driver and same power at all times.

Single plate 9 puck

single plate 3 puck

Twin plate

Which one would last the longest ?

Heard some say twinplates dont last that long compared to singles then the other night a mate swears that his friend wore out a 3 puck single plate in 6 months !!!!! which has got me a little concerned as I have already ordered the 3 puck single ceramic for my car :)

The more pucks the better!

The more surface area you are covering, the less over all wear.

There is alot more strain and wear on 3 pucks then on 9 pucks of equal size, thickness and compond.

The same goes for twin plates, as this states, there are 2 plates of pucks then just the one.

Hope this helps

ok so would a 9 puck hold just as much power as a 3 puck ??

or would the 3 puck hold more ?

If the 3 puck does hold more wouldnt it balance out in the end ?

ie 9 puck wont be able to hold the power and hence wear out at a faster or equal rate to the 3 puck.

If we are talking about the same clutch and the difference is 3 or 9 puck, well the 9 puck will hold more as long as it is the same size, width & compond as the 3 puck.

When you have more of it to grip with, it will hold more power. Because you have more surface area eg. more pucks - there is more compond to grip the flywheel and pressure plates

Ok.

Please dont take this the wrong way cause im not doubting your knowledge.  

But if we go by your theory shouldnt a full face clutch be better than any "puck" clutch ??

I mean what are the advantages of having the pucks then ?

Yeah you have a point there, When I was replacing the clutch the guys that make them here in Adelaide told me that a clutch with pucks will do better than a full face (performance wise), the full face will be more friendly for day to day driving.

So interested to see who is right here, cause I got a 5 puck one.

If the full face clutch was made with the same compond material as the puck type cluches well it would be better. Most of the time it comes down to manufactering costs. There is no point in placing more pucks or clutch compond if increases the price and does not suit the market intended for.

If you look at a Nismo twin plate clutch, they have almost a full face clutch with the puck style compond which is made up of ceramic compond. The reason for the gaps is heat and the ability for some flex. because these use a large ceramic pad (puck) they are more expensive.

I rang Adelaide Clutches (Xtreme) as they can replace the ceramic pads on them. I almost fell over when then gave me the price, think it was like $1200.00

Reason - it was almost a full face with just some slits in them.

If the clutch was manufactured to hold say 300 HP and it does this with 3 pucks of ceramic pad then way had more? If you added more the clutch price would increase and so would the rated HP.

Another thing you could do is increase the puck's surface area by adding more and decreasing the pressure plate force. You get a softer clutch with the same HP rating but this would cost more as manufacturing costs have also increased.

If you think about it, a twin plate works by have more pads on more metal, silimar to say like having 2 fly wheels and 2 clutch plates. The pressure plate does not have to be very high as there is already alot of compond in contact with metal. Not saying the pressure plates in twin plates are always soft but in the case of the Nismo twin plate, they get a high HP rating cause they use a full face clutch with a medium pressure plate. These are some of the reasons why it holds good power and is light on the foot and behaves like a stock clutch.

I think the terms full face might be misunderstood here.

Is the full face made of the same compond as the 5 puck one?

Usually the full face they speak about is made up of similar compond used in stock clutches but the puck version is made up of ceramic compond. In this case the 5 puck one will do a better jop performance wise.

So if you put a full face and a 5 puck made out of the same material, whatever this may be, the full face one is gonna do better than the 5 puck? :confused:

    • Been a while since I've heard anyone mention Kumho tyres. It's like they've fallen off the radar in terms of street/track tyres. I still want to get below 1m50s on the RS-4 tyres at SMSP, just because lol. Even doing a 1m52s lap, going into T1 was sketchy af.
    • I've run most of the semis which are available and sadly you can pretty much rank them by price.  Fast and spendy = Z221, A050, DZ03G Ok and mid range price = R888, V70A, A052 I don't really rate the AR-1 because it's not cheap enough for the performance level offered. Yes, they're much cheaper than A050 but V70A can be had just as cheap and is a much faster and more predictable tyre.
    • There's no current law that stipulates that you cannot eat dessert with a soup spoon, although, it is socially unacceptable of course, shame on you But, there are emissions laws, which is sort of on topic to the OP's questions Things like emissions are, if anything, going to get stricter in the future for road registered cars I believe, 'Merica has yearly emisions testing in some states, the UK has it's yearly MOT testing as well which includes emissions Building, and purchasing modified vehicles may become alot more problematic if you want to keep them registered, how, if, and when each state handles this is anyone's guess  More food for thought really
    • I'm on the AD09, strictly on the street. They are a very nice tyre, have done ~16k km and are near the end, might make it to 20. They are, in my opinion, very much just a street tyre. I wouldn't expect them to be equivalent to some of the others in your list on the track. Although I'd be pleasantly willing to be surprised. My memory of the AD08Rs is vague enough, due to the passage of time, that I shouldn't try to compare them, but I feel as if the AD09 is not quite as "sporty" as the AD08R was.
    • There's a difference between "selling" a product to someone (which, if you walked into a workshop or bricks and mortar store and bought and walked out with it, is just the act of buying and selling) and rolling your buggy into a workshop and having them fit non-roadworthy stuff to the car. And for the latter, let's ignore any potential legal loophole arguments that the armchair lawyer might want to make to differentiate between supplying your own parts to be fit by the workshop or getting the shop to supply and fit. The workshops that have been dealt with in the US for this are in the latter category. It would be near impossible to try to charge/attack/criminalise a shop for selling "for off road use only" parts to someone unless those things were intrinsically illegal in their own right, or had other legislation wrapped around them, such as there is for guns, pharmaceuticals, etc. Well, no. And you knew your argument was silly when you made it. And there is. it might be somewhat harder in Vic, but then that's the price you pay for electing the long list of (unts that you have to run the whole shit hole**. But otherwise, you can put an aftermarket or otherwise tunable ECU into a car and get it run through the whole shebang of emissions testing as part of an engineering cert and, so long as the tune is "locked" afterwards, then that modification is on the list that is approved on the cert. But....it is an expensive process. ** Of course, the (unts who make up a large proportion of the population that eternally try to get around the rules are also a part of the problem and the reason that you end up with draconian rules in the first place. By contrast, SA was founded and the government and civil service set up and run by very sensible types (largely German) who set up good structures that enabled a lighter touch of government on the somewhat better behaved population. it is only more recently that we have followed the rest of Australia down the criminal drainhole of penal colony behaviour and now we have to catch up with mobile phone cameras and so on.
