I am looking for feedback from people about what clutch they run, what power they put through it, the price they paid and how they like it.

Im currently running Exedy 3 puck ceramic, with 290rwkw, i paid 700 when i bought it about 1 year ago and its a pain in the ass to drive on the street but had good bite

Im looking at a Exedy Sports Tuff Organic this time round...

OS Giken twin plate, unsprung centre - approx 320rwkw.

excellent bite, easy to drive on the street, not too heavy. I can drive this quite easily in traffic too. Easy to launch, as you can load it up then feed it out as you leave the line.

it was necessary to have the car tuned where the initial bite is, so you dont have to pick up the revs and dump to get off the line cleanly - but a few minutes of tweaking and its perfect to take off nice and smooth.

not sure how long before this wears off.
It doesn't, I've had my Exedy Sports Organic clutch in for around 10,000+ km now and it still shudders.

Actually i'll be back at the shop tomorrow that fitted it getting new gearbox/diff oil along with checking out all the clutch hydralics just to see how everything is going. I've got a feeling that it won't last me till the end of '04 because I frequent the local drag strip (drop it from 3,500rpm around 10x per meeting).

Hi raist60, we use OS Giken, twin plate in GTST's and triple plate in GTR's. Once you get used to the rattle when the clucth is dissengaged, they are great. Never slip, not heavy to operate and easy to modulate.

Sydneykid - how much are they worth? what kind of power do they handle?

What would you recommend for my 33GTR with about 270kw @wheels?

I have a heavy duty excedy and it shudders sometimes when taking off slow

tip for those with these clutches: when taking off slow try to give it as little rpm as possible, i find this helps stop the shudder, when you give it a few too many revs, (not launching) it shudders.

Hi ferni, about $3K and a twin plate would be OK for your power levels in a GTR. I don't bother with a triple plate in GTR's until we get over 350 rwkw.

As for how much power? Not a straight forward answer. In a GTST we have over 400 rwkw on a twin plate, no problems. It simply doesn't have enough traction to cause clutch issues, spins the wheel instead, even on R type tyres. A GTR with more than 350rwkw would need a triple plate though if it had T type tyres. I have used a triple plate up to 600 rwkw, where the gearbox became more of an issue than the clucth. A quad plate becomes necessary according to some people over 600 rwkw. I don't have a 1,000 bhp engine (yet) so I have no experience at that power level.

There is of course more than 1 type of OS Giken multiplate clutch. We use the "race" style which has sprung centres, but no anti rattle pressure/intermediate plates. There is solid centre "race" style as well. And sprung centre with anti rattle, which would be good for a road car. They are only slightly different BHP ratings.

Hope that answers your question

What would you suggest for a street car (my gtst) that gets its arse caned every other drag meet - slipped from 5-6krpm regularly - and generally smashed and abused at every possible opportunity?

P.S. That car's your hero? What is it?

Hi Adrian, I would go the twin plate with sprung centres and anti rattle.

PS; Apexi V-max R33 GTR, 8.8 at 165 mph, has AFM's, Power FC and runs 9.3 to 1 compression ratio.

shouldnt it be runnin a bit faster at 165mph? like 8.5?

Your right, typo by me, it was 8.47 at 165.75 mph to be precise at 2 bar. On the same day it ran an 8.8 at 155 mph at 1.85 bar. But that's not why I like it, it's because one car, on its own, kills off so many myths. It says you can;

1. Run AFM's and be as powerfull as cars without AFM's.

2. Run a Power FC and be as effective as cars with all sorts of far more expensive ECU's

3. Run 9.3 to 1 compression ratio and make over 1,000 bhp

There are plenty of cars that are evidence of one or two of these, but in this one, single car the 3 biggest myths in Skylines are killed off. Bottom line, it proves this to all those sheep who follow the line, removing the AFM/s, dropping the compression ratio and sticking a map sensor driven ecu in it is the only way to go fast.

Now you know why I like it.

I use the Just Jap 5 puck ceramic with the sprung centre. Drives mostly like standard except reverse parking up a hill when it shudderd a bit and can rattle when disengaged in those cases.

Good take up, not too hard and will bite enough to chirp third pretty hard on standard boost. Being ceramic, on a hard launch, even as you ride it it will take up very suddenly after a little slip and away you go.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
