A very good single plate can be better than a twin plate -- its about the quality of the plates not the quantity.

That said, a twin plate almost always has more clamping pressure (ie it garbs harder) than a single plate.

totally agree karen. personally i dont like the way the twins grab, they are harsh and i can just imagine what they are doing to the gearbox

Actually you know what? You can do whatever you like big boy. I like that kind of toughness in a man :(

Jim Berry will say anything that goes against twin plates. They work, regardless of whether he likes it or not.

and to think i got into shit for expressing my opinion.

one reason major clutch making companies (i.e os, orc, hks, exceedy, nismo) use more plates is to obtain a higher HP capable clutch, whereas say a well built single (jim berry) only needs one plate as the design of the springs & tabs etc are of such high quality it only needs the single plate. so inother words, the 'major' companies clutch designs are rather shit compared to one from jim. he also doesnt just do singles, he also makes twins (imported from europe) and he modify's the regular twins so they actually work properly. also one very fine example of how capable his clutch is, TWOOGLE (the 32 gtr drag car owned by dirtgarage off here) use to run on one of jims, 2 full years of racing with 440awkw and not one problem.

who would u rather trust and believe, a guy who'se been in the industry for 27 yrs and does solely clutches, or a major company that churns out 1000's of clutches off an assembly line for the domestic market.

I'd definately get that clutch rebuilt if you can, its got such a nice feel and control. Although Yahoo auctions said it was a Nismo twin plate, be prepared for the a small chance it may be a different brand or type, i've had the same thing happen to me before.

Wow, snap, never mind what I said about mercurry being expensive, they have come back and out-quoted everyone. Asked 850 for the rebuild and 550 to take it out and put it back in.

Nice price from Mercury! I don't see how you can beat that deal.

PS. if anyone gets a tough single from Jim Berry can you please let me have a small drive even if it means just in a car park. I would like to know first hand how they feel. I have only driven lines with stock or double/triple Jap clutches in them so I have no basis for a complete comparison.

If the re builder knows what he is doing he will do all the things you mentioned and still have two plates...my NPC rebuilt clutch has to be driven to be belived! It is 100% better than when it was os spec and as for grabbyness? well there is none it is as easy to drive as any full face single plate clutch I have experienced. Also from memory Bennos clutch is docile as well

when TWOOGLE upped the ante what did they go for?

Ian good option on the rebuild if done well you will love it, I will have to let you have a quick drive of mine if I see you before yours is done

Sure andy, thatd be great.

I just gota look at my fundage situation before I commit to this, the cars still quite driveable atm so I might be able to push it back till after mid-feb.

Just go real easy on it because once they slip they really drop the bundle quickly...mine went from mild slip to not being able to get on boost at all within the space of about 3 weeks

Actually you know what? You can do whatever you like big boy. I like that kind of toughness in a man :wave:

Umm Jim rebuilds twins as well....and I know alot of cars running his clutches...that run decent times and actually outpower "Japanese name brand twins" with a single...

Call Dan I could not recommend him more, or that clutch place NPC...they do good work on rebuilds also.

Mercury outsource SOME of the work they do, so find out where it is going before forking over cash...

If it helps...

i just had my clutch done with the help on Dan. I won't be taking my car anywhere else when it comes to mechanical. I got a great price for my clutch AND service, but now im poor LOL.

I personally didnt like the drive of a twin plate, due to the strong grab it has. I went with a 5 puck button clutch, which now i have 600km on, and it is beautiful. I was more happy with this than the Single organic plate I had in it before.

Im the person who jumps on the highway, go through a little traffic, essensially I am nearly an everyday driver, so I needed that comfortability in my clutch.

I suppose, Ian, you do a lot of driving to your lady's (Not ladies LOL) house via the highway, so twin wont be so harsh on your valuable valuable leg =D.

Good luck with your selection, Im sure Dan will be more helpful than anyone else with it.

if ur willing to drive down to ipswich, i can get u a drive in the 33 gtst i recently put one of Jims full mony's in

when TWOOGLE upped the ante what did they go for?

im not sure of the brand, but they changed as their sponser required them to run their clucth, otherwise paul & stacey would still be using jim's clutch :P

Send me a PM dude with when your free etc. Only thing is with the RB20 the jimberry clutch would probably feel a lot harsher than on the RB26.

But for me Id go a JimBerry or Nicks clutch clutch, then get whichever mechanic you trust to install it. But thats if it were my money, which it isnt.

It's a good thing I use NPC to rebuild my clutches. I don't believe in marking up someone elses work so Ian will be getting my cost on NPC rebuilt twin plate, and then just the labour to install. And if he decides to change to a single I'll smash anyones price on that too....dare me? lol just kidding...but seriously, do it!

Mercury reckons a GTR will shread a singleplate.

Tell them they are full of sh1t...i raced for 2.5 years on a Jim Berry single plate with between 400-450 AWKW in our race car....never even looked like slipping. Quite honestly it was the best performance part ive ever purchased in my 15yrs of car modifying.

and if you don't want to tell them they are full of sh1t...tell them to ring me...i will!

EDIT:due to sponsor commitments ive changed my clutch type and brand..will let you know how it goes.

Just gave the old clutch one last blast around the mountainside, it was slipping a fair bit on WOT but not so much on 50% throttle. Its definatly getting worse tho, maybe I should stop booting it so much? Haha... Its going in to get fixed tomorrow tho, im going to miss driving her while shes away!

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
