Got one in mine as it came with it.

pros,

handle high HP

handle a shit load of abuse(high rpm launches)

last a long time still going after 5 years of use

well built and engineered

no slippage

con's

gearbox breaker (no spring dampers or give)

bitch in stop start traffic

I thought more torque loading etc that the clutch lets through (quad vs triple) would mean more stress on the gearbox (physics), unless it has damper springs etc to take up shockloading. Still punishing gearbox though.

OS GIKKEN STR twin sounds good.......

Yeah i thought the same thing, Kier wilson explained it to me and showed me the differance between the clutches. Somehow the quad plate puts less effort on the driveline than the triple. if indoubt feel free to give Willalls a call, they had the trpiples in both there GTR's and now run the quad's as they found them easier and more friendly to drive. YEs they are the OS distributers here in S.A and would try to make a slae off the quad rather than the triple but i got the quad at the same price.

Fair enough, main thing is as long as you are happy with it, go with it.

I'm happy with my os triple as it has lasted so long (daily driver, 380ish RWHP) and only one busted g box so far, 3rd gear.

well the number of plates has very little bearing on driveability at all.

two equal clutches. both puck type. both metallic friction material. both same pressure plate. both solid centre. one is a tripple, one is a quad. I can tell you now they will both be the same to drive.

things that affect driveability of a clutch:

force of pressure plate

type of friction material used

style of plate (full face, puck type etc)

sprung/dampened centre

saying a quad plate is easier to drive than a tripple is still a useless statement. there are hundreds of types of each clutch. if I had a sprung centre, full faced, 1000kg pressure plate tripple plate. and on your advice that a quad plate will be better went and bought one. and it was solid centre, puck style plate, 1600kg pressure plate which do you think would be easier to drive? and kinder on the gearbox?

exactly. :) my point is. saying quads are better than tripples for driveability is not acurate. of all the factors in clutch design it probably has the least impact on driveability. and yes I've driven plenty of singles, quite a few twins, a number of triples and a couple of quads. I had an OS tripple in my GTR for over a year, and an OS twin in it for about a year.

so you guys wouldn't recommend a triple plate for daily driving? What power will a streetable twin plate hold up?

I converted my solid centre HKS twin plate to a sprung centre. Absolutely transformed the car (was a bitch to drive previously in stop start traffic) and seems to be surviving 400 rwkw abuse OK.

yep, massive difference between solid/sprung centre clutches.

and ookami, like i said, it depends on the type of tripple we are talking about.

if you are talking OS solid centre, puck style, tripple then no, it's no good for daily driving. if you are talking full face, sprung centre tripple, with a not too extreme clamp force then yes, it should be fine for street use.

Just get Jim to make you a clutch if your worried.

Tough as nails, great for street driving

best advice anyone could give you....

i daily drive my GTR, jim berry built mine.. it is a single plate button with a carbonics plate.. bites HARD.

and considering he built it cheaper than what a stock replacement costs... can't go wrong

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
