So Clutchnet has been advertised by us upper HP guys as being one of the only clutches that can hold massive amounts of HP. Well, that's true, but only for a limited amount of time. After about 13 months, the disc finally met the same fate that all the other ones did. The springs exploded out of their retainers.

IDK what causes this. I'll admit that I don't drive like a grandma. I beat the shit out of it everyday, but clearly, the Valeo crap that all the a/m manufacturers use is worthless. Or maybe I just need to switch to a solid hub.

So I called Clutchnet. I had no intention to blame them or ask for a refund. I got plenty of use out of the disc. The usual guy answers the phone, and I can't stand him! He sounds arab, I dunno, but I can NEVER understand this guy, so it only irritates me more. Did they outsource this company too? lmao.gif
I told him what happened and asked nicely what the cause of this may be. He says that I must have installed it wrong, or my "tranny is out of alignment". I'm like "WTF?", but still remain calm.

Me: "How can you install the clutch wrong when you use the alignment tool, and the tranny attaches without any force?"
Him: "I don't know. I can't tell you. This is just what I kow from experience" <--remember this part!
Me: "Well, what could be out of alignment in my transmission, the input shaft? It's a basically new tranny."
Him: "Yes, it could be your input shaft. It could have come misaligned from the factory even if it's new. But I'm not a transmission expert, so I don't know much about it."

K, I'm f***ing upset, and hang up. Now how could this guy just randomly make up BS reasons why the clutch exploded and claim it's from "his experience", but then tell me 2 minutes later that he has NO experience in transmissions?
I'll admit that I'm no expert either, but don't know how the hell the input shaft could be "misaligned" and this is (by coincedence) the same excuse Spec gave me. So I call the local, but reputable tranny shop and ask him about it. At first, he's thinking I'm insane and wondering what I'm talking about. "Misaligned? How can that happen?", he says. So I explain what Clutchnet told me, and he tells me they're full of crap. There's no way that input shaft can be misaligned. Bent 'maybe', but you'd KNOW it, and that's a rarity. So we both laugh it off. Sure he could have asked me to bring in the tranny and do a worthless check on it and get money for it, but he knows it's BS. So what would he gain by lying, you know?

Well, I'm stuck, unless I can manage to locate the Ogura or ........something. IDK

So, even though I can't stand Clutchnet anymore, I went ahead and paid $130 for the solid hub and thought I'd give it a try, at least til I can figure something else out.
So I'm without a car for a week already. But, it got to my door in 4 days. Great!
I go to install it. Match up the PP, and..........it doesn't f-ing fit!!! The splined hub literally goes though the center of the PP and takes up the space where the TOB goes.

OMFG, I'm fuming. That was on friday afternoon, so now I have to wait til 11am my time (9am PT) to call them.
Again, I get the same asshole I can't understand. I spend 5 minutes trying to explain what's wrong, and then "Oh, I know what's the problem. We forgot to machine the hub down so that it fits your car."
So yea, they're using a hub from a completely different car and cutting the hub in half to fit the Tib?
Him: "Send it back, and we'll send you another."
Me: "Well, can you send me one right now since I can't wait that long?"
Him: "I'm not sure if we have another in stock. We usually don't have that many of those here. I'll give you a call later if I find one."
Me: "Ok thanks."

That was on Monday morning, and I still haven't gotten a call yet. I'm waiting for 11am to roll around.........

man, I hate it when rings get stuck in my pp....

anyways there has to be a better solution out there. What do all the cars with 500+ whp run?

I just picked up a act street clutch so we'll see how that does. I didn't want to have to use their 6 puck on the street. My stock valeo has held up till I started running 10 psi in first gear then in just starts slipping.

A 6-puck is not that harsh of a clutch, and probably won't break on near stock power. I been daily driving it for 5 years with different brands.

IDK what they use over in Korea, but Redz is gonna come in here any minute and swear up and down about the heavy duty Valeo on KSPEC or SFR. wink1.gif

Sorry, but the Valeo hub is exactly what's exploding. So unless I can see that that part has been upgraded around the springs, then I'm not buying it.

You can still see it's made by Valeo and uses a pull style TOB. There's no pics of the disc though to show the springs.

I'd definately like to have the Ogura that's sitting next to it though!!!

I'm gonna start looking into the pull/push conversion. I'm not sure if it'll help, but there's got to be better choices in the clutch brands with it.

who's running near stock power!!! must be talking about yourself! nana.gif

There has to be a solution because our weakest link seems to be our clutch. what kind of clutch do dsm's run? We have very simliar motors and there are alot of them running 400+ all the time.

dude do you want a ougra or OS type r. twin plate... clutch net is shit even here. the koreans wont even use that crap... to you all any over 300 you must run a twin plate clutch there is no way around it yes they cost the $$$ but the shit will never blow up or slip. i beat the shit out of mine for 2 years. + any ogura or os is from japan. they are a coustom order so you wont find them on the internet... john let me know what you want to do you dont this this shit..

IDK???? who makes that. i have never head of it, as for you link there you see in the pic that blue POS made by DTM... you dont want that. you want the gold colour one...

yeah they talk it will hold 450hp.. but no where does it say how much TQ it can handle now does it

Yup, I am going to say it. Most of the mid power korean guys use the VHR setups, and I've never heard of them exploding. The one on our I4 GK that's pushing 450 WHP, daily driven, runs one. No problems.

why not just do a push style conversion and be able to use many more clutches and hold alot more power.

Supercow,
The dsm's ive been workin on lately are using an ACT-2900 PP...thats on the 464 hp 2g and it holds good. This clutch is holding 18 psi and a 40 shot.

John, while an Ogura would be nice to have, it also costs like $1500 and it's not like I can pick up the phone and order it. I'm sorry, but no way in hell am I gonna trust $1500 to float over there with all the shady stuff that's happened in the past. It's just too much money to trust in anyone's hands that I can't personally "kill" if they don't deliver. I might trust SFR, but it's not on the site, and I'm sure they would want their share of the profit on top.


The DSM clutch is much more affordable. I just need the parts list for the conversion. Either way it would need to be done since even the Ogura is a push style.

John, your pictures are not working in the conversion DIY!!
http://www.rdtiburon.com/index.php?showtopic=12029
And if you could ship us the parts needed, then we could do this conversion.


Demon_Fox has built his own conversion and used a non-turbo eclipse clutch. I talked to him and he said he's working on the pics and details.

Can it be that the fact you have an LSD, kills the clutch ?

If nothing slips, something has to break. right?



The reason I'm asking is cause I have a quaife, stock clutch, near stock power, and last time I did a 1/4 mile (mind it is a new clutch with only a couple of hundred miles on it) it slip in the first two gears.. can it be the problem?
