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!

    • Yesterday's day in review: All the wiring to the lights up the front how I want it, is ran, terminated, and all to length. The only lighting up front I haven't finished is the side indicators, as I need to get to the partly cutup factory loom, and find the plugs for them. Interesting note, the side indicators use the exact same plug that's in the doors for something else that I don't remember what it is... So that plug better be careful...   Power steering solenoid, on the R33 is variable, and from memory PWM. The Ford's control from the docs I have so far, is it's just a on or off control. So I'm not sure it's what I want, and in any case, power steering running, but at its heaviest (solenoid off) is likely what I'll want anyway, so I'm not yet touching it at all. All the wiring I can complete so far, is done. There are 3 wires I need to make a plug for at the ECU, and these are just for the vehicle speed sensor, of which I need to get a T5 from an AU, so I can use its output that has the speed sensor on it. (My car doesn't have ABS, otherwise I'd set it up to use one of the ring gears on that). I need to buy new headlight globes and front parker globes, otherwise I could show photos of lights working. Current fuel lines in and out on this motor are "5/16". I'll order hardline, and some AN fittings for that, and I just need to 100% check fuel line size at the tank end, to get the ends for it. I'm also looking at a few options for the banjo bolts to AN fittings for the power steering rack. I'll pull the reservoir off the Barras PS pump. There's an off the shelf fitting for that pump for a -10 AN feed, and it'll use a 16mm to dash -6 an outlet to feed the rack. I'll be making my own power steering reservoir, I'm going through the thought process at the moment of how I'll run the baffles, and I need to research another idea for it too.
    • Two inlet runners changes the engines characteristics requiring less fuel to make torque at different points in the rev range. The smaller diameter inlet runners on the DET increases air flow speed, which improves atomisation of fuel, particularly in low load/idle for better burn, and in specific areas of the engine, (areas you would use when driving normally) increases the efficiency. All of those items change how efficient the engine is at different speeds. The changes on the neo help slightly to improve emissions where it matters. The overall improvements won't be the likes of going from an engine built in the 70s to an engine built in the 2000s, it's just a small step. But still leaves it the RB with the best chance of improvement.   As for your comment about the whole using a cat to not need to worry about those gases. Two things, no system is 100% perfect. It won't eliminate everything. So reduce the quantity you put into it, you still reduce the output. Two, make that system do less work, and it's likely to survive a little bit longer. Funnily enough to, one trick employed to get cats up to temp, AND to drastically reduce emissions before they get up to temp, is to reduce ignition timing.
    • Maybe I should have written that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂
    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
