Need A New Clutch?

[Mark0]

My JB clutch is working like a dream

[R31Nismoid]

Well..... I specifically asked for a clutch that could handle 600HP with odd track days & drag-strip work (+ a specific reference to DirtGarage's clutch) .....unfortunately in my case, it was obviously not a 600HP rated unit.

You ran a clutch rated to 600hp... with 600hp (or a tad more)...

In all honesty, what did you expect?

Its like getting a tyre rated to 300km/h, and doing 300km/h just to see if it will blow out.

A smart man would get a 330km/h tyre or a 700hp clutch IMO to give you headroom rather than tempt the devil

I went solely on Jim's advice, he reckoned the twin plates were a waste of $$ as his super-single plate would be more than ample...........so "in all honesty" I expected the clutch to work, but given you're all seeing and all knowing you obviously knew what I discussed with Jim PS my mph at the strip when the clutches actually failed indicated the engine was well under 600HP (120-122mph).

O well i have the same JB clutch and have run about 5 120-122mph pass's and its been in my 300+awkw car for 2 years now must have just been unlucky.

Wholly heck Batman - 5 passes..............

Your the one that said your clutch died on the frist pass. I have done many pass's just showing that i have run a couple of 120mph pass's so we may have similiar power

I hear a few people commenting on them being very hard on take up, does everybody experience this or is it just Jim's "full monty" that drives like this

I have the decision on what to use in the 200SX, the box blew, so was thinking of using one of Jim's clutches..... i have just been a bit concerned on the clamping force, 4000lbs in this case, and the effects this may have on thrust on the RB's crank.... its a hell of a lot of clamp

Can anyone comment on how nice the pedal is on one of Jim's clutches that has above 3500lbs clamp??? i would have thought you would need legs like Arnold to use it

[Abo Bob]

I think mine has 4400 pounds from memory. I remember Jim saying it was the most he ever got out of a standard GTR clutch. I wouldn't say you need legs like Arnie but the friction point is very small.

Remind me some time Brad and you can test it out.

I'm only aiming for around 220kw. Should I get the Jim Berry "mini-monty" or will the Exedy HD Organic clutch be sufficient? If I get a clutch from Jim will I have to purchase throw out bearing etc separately?

How about this as an alternative?

Exedy "Sports Single" Sports Organic - NSK-7056SO (RB25DET): $573.65

Spoke with Jim Berry today. He's making me up a clutch, it's a level below the "mini-monty". It's got the "full monty" pressure plate with an organic face or something. It was all a bit double dutch to me but I'm sure I'll be satisfied with choosing Jim Berry over Exedy. Just need to book it in to get fitted somewhere now.

hmmm,

my JB 'full monty' slipped on the weekend when I did a cupple of 6k+ launches in my R32 GTR

its a carbonic clutch plate with 4000lb pressure plate and has done 3000k's

first launch it fully slipped and did not properly hook up,

second run it slipped and eventually hooked up. After the launch I went to drive off normally and the clutch wouldn't engage and just slipped and shuddered.

I got the car moving and it seemed to right itself (drives fine now, but I havnt attempted another launch)

I'm a little dissapointed as my 'stock' GTR makes only 230AWK and when I did the launches I was not running my usual 1bar, I was only using .7bar.

It also makes a bit of a clicking sound when depressing the clutch.

The unit was installed by my tuner following Jim's strict instalation instructions.

fitted the unit set me back close to $2k and I am not a happy camper

My new JB clutch is in. Working well so far, it's just a Heavy Duty organic style. Not full monty. It seems to make a bit of a clicking sound when releasing the clutch, but the stock one did that too, so hopefully it's normal.

Sucks to hear about your clutch slipping. Nothing worse than wasting ridiculous amounts of $$$ on something that doesn't do what you want it to!

On a side note, when I went to pick up my clutch I paid by EFTPOS, it wasn't til I got back to work that I checked my bank account and noticed no money had left the account.. checked the receipt, my card was denied for some reason. If I was a scumbag I coulda got a free clutch haha, rang Jim up and direct deposited the cash straight away though.

how do u drive the car day to day? as in do u slip the clutch?

[Betz]

I 'slip' the clutch as little as practical to get the car moving smoothly.

the take up has always been very fast,

I usually give 1500rpm and come off the clutch quickly and can feel the clutch hook up smoothly.

changing gear I can get smooth changes without needing to induce slip and its only when driven hard that gear changes are a bit violent.

my pedal hieght is a little higher than I would like, but it has always been like that even when the clutch was first installed.

the clicking sound when depressing the clutch is like the diaphram has a cupple of broken fingers.

the clutch also squeals when its cold and is engaging, this goes away after a few k's of driving and indicates to me the clutch has been run in and the high points knocked off.

if its dead then its pretty piss poor value 3000k's for a $1500 clutch

Why do they recommend you to get a new fly wheel sometimes, when purchasing a new clutch

so this may not happen...

[Sheng]

^^ holy shit

[sloutch]

That guy probably did a 9,000rpm launch.

[marmo]

Just spoke to Jim today,

getting him to do my nismo g-max twinplate clutch

ill let everyone know how i go once its in, expecting 330rwkw through it (rb30et vl but)

[bigslick]

Need to do the clutch in my R33 gtr soon.

Anyone had any experience with this Xtreme clutch?

It's 1260kg clamp load (approx 50% over standard), and a dampened hub with cushioned ceramic facings.

At the moment I might be making around 230kw atw, but need it to handle 330kw atw.

Ballpark price i've seen at the moment is around $1100 for the kit.
