I went down to East Coast Supercharging and picked it up. I paid $955 for it. From the few reviews I've read on this clutch as well as Doug's (at ECS) testimonial, it seems this should be awesome. I still have the stock clutch and this will be my first time attempting a swap. I printed out the InstallUniversity.com and Cartek clutch install instructions, so it shouldn't be too bad. I was going back and forth on so many clutches before I settled on this one. I originally was going to get a Spec 3, then had a RAM Powergrip HD on order, but cancelled it after speaking with Doug at ECS. Here's a couple of pics of the stuff I have for the swap...I also have McLeod Adj. Master that's for sale in the "for sale" forum. I was told that it flows too much fluid for this clutch, so I'm just going to order a new GM Master Cylinder.

Is there anything else I will need to complete this swap besides some ATF? I know I need to get my hands on a pilot bearing puller/slide hammer pulley but I'm not sure where to get that.

 

Awesome man let us know the results. What did that 955 include?

 

Keep us posted would love to hear your results...i am in need of clutch and i was looking at those

 

Let us know your impressions of this clutch once you install it. You can rent the slide hammer/pilot bearing puller from any Autozone. I'm also interested in knowing what the $955 included.

Also, be sure to have a swivel extension (3/8") and a real long extension (~20") to get the tranny and bellhousing bolts off.

 

The $955 includes a clutch disk, pressure plate, flywheel, new GM slave and the enitre thing is balanced at a machine shop.

If you dont already have one, the only thing you need to buy is a stock master cylinder. They dont want you to use a Mcleod adjustable master with this clutch.

The thing drives like a dream compared to any RAM or Spec clutch I have driven.

 

Contemplating this very same install myself. It would be totaly solo though, not sure if that works for bleeding the clutch.

 

Im ordering mine tomorrow

 

So dose anyone have some more input on this clutch? My spec stgII went on its merry way. After hitting 494hp at the wheels. Looking for a good upgrade, am leaning toward the spec stg5. Hear mixed reviews on spec and looking for better options............

If and when it comes time to get this clutch what is the correct name and description for this unit-assy.

 

How's it holding up? Whats your rwhp?

 

what is the break in procedure

 

Nice...

 

OK. We all want to know how it holds up. Keep us posted.

 

I think you'll be pleased with the clutch.

As for the question of how the Aussie clutch is doing. Its doing well. Tommy' is taking a weekend off from farming in a week or so, and going to Dallas. Lou G. is going to go put some hot laps on the car at motorsports ranch with Tommy in the car riding shotgun, and then Tommy is going to make some laps in the car.

Blu-by-U has been driving his around on the street and loving it.... As for the HP level it will take. I know Pete and they guys have been conservatively estimating its maximum service life at around 700 HP. I know it will take more, but thats a nice safe area. These are just a fewof the folks I have spoken with lately. All have been very pleased. I have another one of these clutches going into an all out max effort car solid roller car which should be together very soon.

Big Shawn down (nicknamed Matters (shortened for of Size Matters, he's a body builder). Anyhow, his car is the one in the video froma Australia running 10.4 @ 143.

I talked with Pete @ Textralia, and he's had it at two recent track events. At the LS1 nats he made about 40 runs over the weekend. This past week he went to a T&T day, and no one showed up. So, he hot lapped the car all day.

My understanding was that he made about 14 back to back passes (in a car making 800+ RWHP) with literally zero cooldown. After his last pass he started to worry that the clutch might be starting to give just a little bit .

So he took the car home. After letting the clutch cool down, the car had zero issues and he's out driving it around again,and he's just beside himself with how awsome the car is running.

He's now been informed he needs to let the clutch cool down between every few rounds if he's going to hot lap it like that. It probably wouldn't be an issues except he slips the clutch a BUNCH (like all the way through 1st gear) since its a small tired car. He just wasn't giving the car any time to cool the clutch down adequately.

So, unless you are making more than 800 RWHP, and you make 14 hot laps in a row you should be ok at this point. So, I think this probably covers most folks with a fair margin of safety....

Here is Big Shawn's quote on the clutch:

 

I just bought one too. I make 553/614 to the wheels, so I should be a good testomonial to this clutch. It will be about two weeks before I can get it to the strip though.

 

Mine has been installed for a little over a week. I dont have the proper amount of miles on it yet for the break in period so I'm taking it easy as instructed. But the differences are tremendous already. First: the thing grabs a half inch off the floor the way it supposed. Slight shudder under very low rpms, its doesnt like feathering to low rpms much, its wants to grab and go... It projects a much better grip than my stocker did. I never has a spec so I cant compare it. All in all this clutch is marked improvement over what I had, which was stock with 75k on it. I'll re-post after the breakin and I dump here a few times. I'm making 375 to the wheels so I anticipate never having trouble.
