got my car dynoed at 220rwk and my exedy sports organic clutch which was supposto be rated to 240rwk has started to slip. worst part its only done 5-6,000 k's tops.

i wont be making more power than i currently have but i want it to last up to 280rwk just incase i want to push for a new setup later on next year.

what would best suit my application?

i do not want another exedy clutch. they suck

thanks

hey mate exedy isnt all bad i got a brass button single plate on my gtr 200 kw and 625 n/m of torque last time it was dinoed..... it handles full 7000 rpm drops and think that with the amount of torque ive got it is holding up great. had a few extra things done since dinoe so probs puttin out an extra 20 kw now. by the sounds of it ur clutch was just standard heavy duty? no brudd button or nething?? they are tricky to drive in peak hour traffic but u'll get used to it!

hope this helps at all

peace

it was a heavy duty organic clutch. they so over rate their clutches though

If you think you know enough about clutches to know that exedy overrate them, why do you need one recommended for you...? Seems like you dont even know what exedy clutch you had anyway....?

Also going by your other topics youve posted you like to take it to the drag strip occasionally...? Maybe you just didnt have the right cutch for the job? A clutch designed to ake 250kW will do just that. If you want something you can pop and dump and launch at 5000rpm then maybe you should read the catalogue, and pick one properly, not just go for "heavy duty organic".

I run an exedy clutch - bought direct through a family who runs a department at exedy and could buy your or my car with a weeks pay - behind a 10,000rpm SR20 in a purpose built race SSS Pulsar. This see's nothing but abuse EVERY time its driven. Cant fault it.

that could be you first and second gear - wouldnt clutch do it in all gears...? First and second cop most abuse on strip days.

As far as engagement height goes - could be an adjustment issue. Does it pick up and bite well when released, or does it rev out then come back down? Is it slipping?

yes i understand what you saying but most times i don not rev n dump and it still slips top of 1st gear

it done it tonight more so in 2nd gear. just revved and went no where

This has nothing to do with the thread, but anyway. You quoted your torque figure of 625nm..... i'm assuming you read this off the dyno sheet? As far as my knowledge serves me, that would probably be a load of crapola. I wouldn't believe that figure. My old dyno sheet tells me i had 200hp & 722nm, i don't think so jim. Ignore the torque reading, look at the kw/hp.

Maybe a cushioned button clutch would suit your needs and should cover your power goal. Otherwise just a button clutch if you don't mind the harsher engagement.....apparently.

its definitely slipping then. Get it checked out by a specialist just to make sure that its engaging and disengaging 100% and that there are no dramas in any linkages etc, but if all else fails then yeah she may just be goorne. Your 33 is no doubta lot heavier than a race prepped SSS, so a lot more stress will be put on it as far as launching a car goes. All clutches like that will wear out - they are designed to. It is the weak point in your drivetrain that stops everything else from getting smashed up. Even a 500hp clutch will wear out, a lot of it depends on how you drive. This is not a dig at you - just cos you put a lot of strain on your clutch and blow it, doesnt make you a bad driver. It not so much a matter of driving good or bad - its driving soft or hard.

I have an XF falcon with a 4spd, and i used to go through 500hp clutches like they were nothing, just cos its a heavy car, and i drove it hard. But i know that if my clutch didnt have a bit of give and wear in it, i wouldve being going thru diffs and gearboxes. MUCH more expensive.

PS the clutch you got isnt all that 'heavy' duty... its okay for driving a car with a bit of power, but if you like to give it some stick and chirp through your gears occasionally, and with a bit of strip action thrown in, you need to get something, as above, like a cushioned button. Bit more streetable than a solid button (on or off) clutch that will be more fogiving to the way you might want to drive, without transferring too much stress to other parts of your drivetrain.

would a exedy cushion button be a good application for me even if i up the boost and make 240rwk? different brand?

and how will the cushioned button clutches be on my gearbox and diff compared to what i have?

im a newbie when it comes to clutches :)

yes as i said this is what it pulled on the dyno so of coarse i read it off the sheet. i know dynos are only a tuning tool and all read differently but it was done on a dynalog dynometre for 4wd just so u know makes.

1 bar of boost and pleanty of goodies... and most gtr's with same mods as mine same ecu putting out 240kw atw so going by that most kw/hp figures are a load of crapola off a dyno too! so i dont really know why u had to come on someone elses thread and tell me something i alredy knew...... (dynos areant exact)

i was just stating what i pulled on a dyno so r33god had an idea that brass buttons were a tuff clutch my car hasnt done many kms on it so far but i can say nothing but good things about exedy and their brass button clutches.

peace!

Tis true what you say, in essence the reason why i said it was because the high torque reading are products of gear multiplication etc etc.

But yeah its about clutches today, so i'll keep it on clutches. Sorry I probably came across the wrong way dude lol.

Peace likwise bro :)

i just drove my friends r33. he has a exedy cushioned button clutch. they feel like a standard clutch and are awesome and very streetable. ordering one tomorow :rolleyes: and my mate told me there good for holding 260rwk?

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
