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:

    • Not specifically the revamp Toyos. In the past I've used Nitto NT01s, which were essentially the same compound as R888 with a different pattern (that's what the internetz said, so just be facts). I did like the NT01, progressive fade, didn't go from grip to 0 grip in a split second. If you look at the serious street/track guys, most are either on Cup 2, A052, A050, AD09, CR-S or AR-1.  
    • I have one of these! It is absolutely useless. It provides not nearly enough force on the bolt, it just slips over anything that is not finger tight. And if it's finger tight, you can use your fingers.
    • You have to take photos of the car in Victoria with a timestamp. So if you have big aftermarket turbo in your engine bay, your car is simply not getting a RWC and you'll be doing a lot of returning to stock, and re-modding after about 90 days (because cars that have had a RWC can be audited after the fact). The law I'm kinda ambivalent about. I can see the logic and the writing on the wall, Cobb etc would be well known for selling to 'wink wink off the street usage' but in the real world everyone knows what they do and where they end up. It'd be like someone selling guns in Australia but "only to people who have a proper licence" but selling them outside of Bunnings instead of sausages to anybody. Like RWC's, and VASS's and EPA, this is enforcement of the actual existing rules. I haven't looked into it but there (should) be a way for people to legally pass their tuned car to be within the rules if they can prove they pass emissions laws that are applicable. If there's not then that's another story.
    • Interesting post(haven't watched the vid). I'm surprised companies can be fined for selling products that are specifically meant for certain applications.  How can you force a customer to use or apply your products in 100% the way intended? People have been misusing products since they were invented. Heck, I ate dessert last night with a soup spoon. Does that mean the spoon manufacturer could be fined? And what of the customers who actually want to use the product for its intended use?   I'm sure we could discuss and debate this for a while, but this is an introduction thread and I dont mean to take over it.
