People with 850+hp which clutch?
 
I would like to know which clutch people with 850+hp are running. I dynoed 914rwhp and have about 2K miles and 3 passes at the drag strip with my Exo-skel and it is toast.

wow, I havent heard those exo-skel's breaking at all, but im running a mcleod twindisc and it has held my 893rwhp for a bit, although it did blow up once on me (but was covered under warranty).

Textralia... look up their website and check it out. it might be expensive, but you can re-surface it for cheap compared to buying a new clutch...and BAM , there ya go new clutch

At those power levels clutches are iffy.. I have not pushed my Vette that hard, so I could not tell you what would work at that level. I am currently running the OZ700 and it is holding 750 to 800rwhp w/out issue..

Did you read my post, I am running the Textralia twin disk clutch (Exo-skel). I am pretty sure Pete will make things right but I just want other peoples opinion on what they are running. I am thinking about trying the new triple disk Textralia clutch.

stevieturbo 06-09-2007 07:12 PM

Strange that you fried it ??

What sort of tyres were you using ? What sort of conditions were you using it when it let go ?

Is it a particularly heavy car too ?

With a few more goes, my OZ700 would easily have taken me into the 9's, and others have done similar.

So I would assume the twin disk is capable of easy low 9's ?

I currently have the triple in mine.... I didnt need it, I just wanted it.

But it isnt as straight forward a fit as the twin would be.

speedracer5532 06-09-2007 07:39 PM

It slips in 4th and up gears when I get on it. The first time I noticed it slipping was my last run at the drag strip the other night on the 3-4 shift. I was running 28" Hoosier slicks then and my car is full weight (3700lbs). I just took the car out for a drive and it is slipping on the street in 4th gear with Nitto drag radials.

How is the triple disk Textralia not as straight forward a fit as the twin?

Tiago 06-09-2007 08:13 PM

I ran a spec stage 5 and it has always been solid, no slip at all even after severe abuse street or track.

Sbertolone 06-09-2007 08:26 PM

i know exedy has a 3 disc clutch available, but does anyone actually own one?

stevieturbo 06-09-2007 08:36 PM

The Exedy twin can barely hold 600bhp, so I doubt their triple would be capable of 900+

MY99TAWS6 06-10-2007 01:27 AM

Well be watching this thread closely to see why that twin didn't hold that power.I thought they were rated like 1200 ft pounds one reason I got it instead of the oz700.
I won't be at those extreme power levels more than once or twice. I plan on daily driving with around 500 to 600 rwhp 99% of the time. and over that 1% of the time.

Still didn't think a triple would be needed until way over the 1000rwhp range.
I guess it might depend on how much he slips it versus dumping it?Dumping of course harder on the drivetrain but easier on the clutch. slipping easier on the drivetrain harder on the clutch.

did you run a shim with the cltuch??My friend did on his to raise his pedal and his exo skel slipped with about 675 rwhp but when he took it out it grabs fine

doesn't supprise me at all...

Triple here on both cars drives good and holds so far had to get used to driving them though can be a little aggressive if you don't get it right lol! I have herd good things about the spec twin disc, but already had these clutches etc... The Mcleod twin is all Speed inc uses in all there high hp cars and it has held so that is all I can tell you about that on no personal experience with it. So good luck and the twin didn't hold in the black car, but I believe that it was preloading it and went to the triple and found that out and now it is right etc...

For a daily driver, esp if you will see a lot of traffic, the OZ700 would have been the smart choice.

The shim was probably holding the fingers open, causing it to slip.

No shim and stock master cylinder.

Are you running the triple textralia or another triple clutch?

Quite a few people have had good results with the Spec Stage 5, and it is a lot cheaper than many other clutches.
