Just doing some research into clutches

Just wondering what power ratings some clutches are

Mainly looking at NPC and Exedy for the moment till i get emails back from other places

Car is 194rwkw atm but will be chasing about 290rwkw (Prob at the most) later this year or next year

so probably a clutch good for 300-320rwkw?

If anyone can tell me what theyve come across, what there using and what they would recommend it would be much appreciated

BTW: Car is pretty much 99% street driven, occasional 1/4 mile runs for a bit of fun, maybe 4 times a year at the most

It has an EXEDY cushion button clutch in it atm that has lasted me 2 years and has been a good clutch, has only just started slipping now and im not sure why, pretty sure it was good for 260kw and I have less then that but anyway

anyways, thanks in advance for any help

dont go cushion button for 290rwkw...

exedy told me they wont hold up to that power level

i went for an HHHDB but it's not the best for daily (i dont mind mine at all but hektik is a lil over his atm lol)

I wouldn't know about Exedy in particular, but my experience so far has been bad with organic clutches. Earlier this year, driving sedately at 60 on the way home from work running a max of 174rwhp mine slipped and quickly died.

I'm looking to crack 300rwkW in a few weeks, in the same scenario as you and I'm running an RPM ceramic at the moment, the heaviest they make and I'm very happy so far. Although I'd like to have gone exedy/Jim Berry I just picked this one up because my girlfriend's parents supply 'em and it was cheap.

Just ordered an NPC 10" Sprung button clutch, sounded the go and wasnt overly pricey :down:

Had a few mates with NPC clutches that reakon they were good so ill see how this one goes, Thanks for all the advice, ill try and remember to post how the clutch goes

Hi guys

Just in case anyone was interested.... I got the clutch in last night and have started driving it and its actually suprisingly good

I was expecting hard pedal and jerky button clutch engagement but it feels nearly as light as my stock clutch! much lighter then the exedy cushion button i had in there before. And its pretty good in terms of engagement, i can do a pretty normal take off from the lights already

Its still got that bite of a button clutch but compared to the last time i drove button well im really impressed

If anyone wants to know it was:

NPC 10" Sprung button Clutch (R33 GTST)

Im very happy with it :wub:

Really? The guy I talked to was pretty helpful and I had a chat for a bout 15mins to work out what clutch would be best

helpful yes,

my clutch failed and they failed to accept responsibility

then they beated around the bush trying to point the blame on contamination

bah, i just went to another clutch joint. dime a dozen

I'm making 250rwkWs and using a hybrid kit

- R32 GT-R 1.1 tonne Exedy Pressure Plate

- R33 GTS-t Sport Ceramic 3-Puk Clutch Plate

- R32 GT-R Nismo Big Bore Clutch Slave

- R32 GT-R Nismo Pivot Point

Car is quite easy to drive, some chatter and I abuse the shiet out of my clutch, holds well :banana:

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
