I'm not a big fan of carbon clutches in a daily driver, their operating temperature window is too narrow. They slip like crazy until they get up to temperature. Even in a race car I have had one inexperienced guy kill one, just on and off the trailer and driving around the pits.

<sigh>

Thanks for the heads up guys...

I've been through seven different twin plate clutches (and one triple) in my travels, some good, some bad, some excellent....

I thought I'd try something new, but after hearing the above reports, I'll stick with the tried and true OS Giken TS2CD. It'll be my THIRD one :)

At least it'll be a known quantity, but I miss out on trying new technology ;)

Thanks Baboo...

I'll stick with the known quantity OS Giken one for now, and consider trying a carbon one later down the track when I'm chasing extreme weight saving :)

Mark Berry, Russell Neuman, Mark Jacobsen and Paul Diemar use NPC twin plates.

Buy a real clutch Merli...not one that comes in a shiny box with fancy stickers.

I'll second the NPC. I've had it in the car for over 2 years and it's never slipped at the circuit or the drags and it's really easy to drive on even with the push/pull converter.

I have an OS Giken Twin Plate in my own R32GTST, I just service the plates regularly, just like brake pads they wear out. In the race cars we only use AP Clutches, 7" in the turbos and V8's and 4.5" in the 4 cylinders and rotaries. They are not cheap, but nothing good ever is. It's the combo road and track cars that I have the most problem with clutches, the compromises seem unavoidable. Either they are snappy and heavy for daily driving or can't handle track work or they wear out real fast. Depite many years of looking I haven't as yet found one that doesn't have at least one compromise.

I've heard nothing but good things about NPC clutches, may try one down the track.

I use an OS twin plate which I just had rebuilt after doing this to it...

Lasted a long time though, and copped some fair abuse. I'm a big fan of it.

Twin plate Direct racing clutch, manufactured by "DIRECT CLUTCHES" here in Brisbane....great clutch and easy to use.

Had one in my STI for years of trouble free driving...recently tried the Excedy....worst clutch by far and after using it for the past 4 weeks, I will be getting the Direct clutch rebuilt.

I originally purchase the pictured clutch for the GTR....but after a test drive in AtomicBomberman (Chris) GTR, decided to give the carbon ATS clutch a go

ive used extreme single plates, os giken quad plate, direct clutch twin (older version) and a npc twin and the npc is the easiest to drive, handles 600rwhp drag launches time and time again, plus hard shifts with a dogbox and it is awesome to drive around town, the engagement is sooo smooth. The os qaud was an absolute pain to take off from lights etc i didnt like it one bit.

NPC twin is $2000 from memory, these are cheap as to rebuild as well unlike the os giken ones, definately top notch. My twin plate is bigger than the quad plate, its definately a serious piece of workmanship.

$2400 retail...a little cheaper for trade

ARP flywheel bolts $110 retail...again a little cheaper for trade.

thats a sprung centre one, mines a solid centre and still a treat to drive, they are absolutely huge for a twin plate too

ive never had to drop the engine xmember to put box in either, just tip the motor right back and ya fine.

    • That R31 was so cool. Only did Orange Park once. Scared the hell out of me.

    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
