Clutch And Flywheel

[Jonnyboy89]

hey boys, staying away from ns.com atm for this topic, i have recently noticed that after full boost around 3700-4000rpm, my car tends spin, almost like im doing mad skids cause i have staunch power or something! obviously its the clutch slipping! now im posting this so i can get an idea about what clutches felow sau people have where they got it done, prices and the likes

i hvae rb20 with 28/71 turbo, fuel pump, remap, fmic, basic shit, making around the 200 mark, only a low figure to needing some splitfires, injectors and afm!

now i have heard obviously everyones opinion will be different, that exedy are better than extreme, but again each to their own! had a price from isc, which was around $950 for 6puk extreme clutch, lightened fly, then i have to pay for some kent to install it! grrr, anyway havent had all that much time to look around and have a sus on prices e.t.c but would like your opinions ideads, contacts in the industry and some all round help!

thanks in advance

well i ran a group buy for clutches a little while ago and am due to do another one soon

thay were a killer built clutch by NPC excedy pressure plate nismo center with Patrol 4.2lt disc machined to suit RB gearbox

rated for 350 kw with a 1220kg pressure plate

only one guy has installed it so far and i hear he's shredded 2 sets of tyres with it

if the other people that need clutch post up in here i will organise another group buy

EDIT

this was the Clutch i organised

<<CLick

my clutch just fried itself too, im heading towards the exedy HD cushion button type but if there is a group buy happening before thurs, count me in

[Fabs_32]

Mine's on it's way out too. I'm starting to get a bit of slip now. Haven't started researching into yet. Don't know what sort to get. So i'm very interested in this thread!!!

[Madaz]

what gear are you guys slipping in and is it only under boost so far

[Ryanrb25]

Aussie Dyno n Tune will Supply and Fit a Cushion button Heavy Duty clutch for around a 1000 bux....go see them, they do heaps of them on customers and their own cars. IMO Exedy is better than an extreme, Ive tried both and Extreme clutches tend to shudder, have even seen one Stick to the flywheel to never come off lol. My Exedy in both my cars has put up with alot of punishment for a reasonable amount of time with decent power. I'd say keep the dollar local and buy an Extreme but Exedy is a much better clutch being Japanese.

ok >>here<< is the original thread that the group buy i made

please dont post in it

i can get those flywheels $100 cheaper too but need a minimum of 5 ordered on top of any clutches ordered and the minimum was 4 last time but 5 is a nice days work for NPC

[Fabs_32]

Mine's pretty much stock besides an intercooler, pod and zorst so no major power and it's sometimes slipping in high revs in 1st and if I dump it in 2nd it's half slip half grip.

It's just starting to go.

[Madaz]

you will easy be able to make it last a month or 2 if you dont boost and dont high rev it

that goes for all you guys go easy on your clutch

once your clutch starts to slip that it no more boost in 3rd and 4th and only small boost in other gears till it slips in 2nd then you know its very soon gunna go

[Fabs_32]

well if I'm not gonna boost it I might as well drive the daily commodore. haha. That was the whole point of buying a 32.

Cheers for the advice tho.

well the 32 is gonna be off the road for 6 months anyway.

I was thinking something like a twin plate clutch coz it's not so heavy. Good idea or bad???

thats just a silly statement when you car starts to brake down you take it easy

twin plate isnt needed for the mods you have just toughen up and get a heavy right foot

I've already got a heavy right foot that's why my licence ain't no more, although my left foot might just need a work out then.

I do plan on more mods in the future. Just bought the car recently. Maybe about 220 at the wheels, i'd be happy.... until I got bored.

obviously fabs32 clutch will last alot longer than mine as his is pretty much stock and mine is running around 60-70 rwk! altho fab should enter a group buy or join in so we can all reap the benefits! so im thinking button clutch also and apparently if you keep a stock fly that its too much pressure with a heavier clutch so you will put to much load on the blah blah, i dont quite understand it all but the know it alls will understand!

as per ryans comment regarding exedy and extreme another person saying exedy is better! as per flywheels i dont quite understand the importance of them, but will trust everyone saying i need to upgrade!

anyone bought from any sponsors here? finding them helpful and cheap or whatever?

i have recently noticed that after full boost around 3700-4000rpm

you know the pedals at your feet don't press the one on the far right down all the way and you should be ok too

apparently if you keep a stock fly that its too much pressure with a heavier clutch so you will put to much load on the blah blah

i don't know who told you this and what context it was in but sounds like an old wives tale

a heavy flywheel will help keep your torque but will slow rev. a lightened chromolly flywheel will spin up a lot quicker but you may loose some torque

Cubes has bought an excedy from Kudos Motorsport

[CRoNic...]

Not trying to hijack this thread, but if you floor it and the wheels start spinning in 2nd and 3rd, it means the clutch is spinning and it's on it's way out?!! My mate thought it was because he had "so much power"

[Damo_R34]

well if your clutch is slipping, you shouldnt get increased wheelspin

[Jonnyboy89]

damo i described the spinning as wheel spin, i actually know its not the wheels spinnning mate! so madaz who did you organise the group buy with the company ? you said you know of only one person who intalled the clutch and hes shredded 2 sets tyres? this mean it needs modifying to install it or the rest who bought them are lazy? also not having much sucess with suppliers nor prices, so if you have connections in the industry hook a brother up please!
