ATS Twin Disc Carbon Clutch w/1100kg Pressure Plate #16134
This is truely the ultimate clutch on the market. ATS has been making clutches for many years, but only recently began marketing their products in the USA. Becuase of their limited marketing budget, you dont hear about this brand as often as Exedy and some of the other brands out there. But the ATS twin carbon disc clutch will likely be the last clutch you ever buy. It is rated at 700ft/lbs of holding power, but has stock enagement and pedal pressure. The entire assembly weighs just under 26lbs, and includes a lightened flywheel and bearing. Becuase it use full floating pure carbon twin disc, these clutch doesnt chatter like other racing clutches, and with the carbon surface, the clutch actually grabs MORE as you heat it up, rather than overheating and slipping like a conventional clutch. We also offer a triple disc carbon clutch, and an option of a heavier flywheel. Email us for details on these items. They are good for well over 1100ft/lbs of holding power. An optional carbon heat treated flywheel and pressure plate is availble for an extra $100. EMAIL US about the single disc, triple disc, and heavier pressure plate options.

 

Yeah, I agree with Todd there.

 

I still can't believe I'm going to spend this much money on a clutch but I feel it is def. going to be worth it.

 

LOL....the clutch is a dream....never thought I would say that about a clutch. Ask Ernie...he loves his too!

Also comes in a triple carbon disc version as well. Good for 1200hp...and that is with the standard like-stock feeling pressure plate. All are avail with heavier pressure plate at no additional cost.

Sharif,

As much as I know the ATS is the way to go I really don't have the cash for it right now. I need bigger brakes and some other safety stuff first and I plan to hold off on it until I get my built motor going.... That being said what clutch would you recommend from the CLutchmaster stuff you offer in the meantime. Power to the wheels is going to be around 400 daily but as mush as 500 on special occasions...Thanks again..

 

What are the price range for the clutch and fly?

 

Sharif has the lowest prices i've seen on the ATS clutch. Z1 Auto's is a little more I think.

 

how about the jwt clutch and flywheel will they hold up alright with the APS TT?
Since I can not afford $2500 on a clutch right now.

Also I read that having a lighter flywheel is not a good thing when going turbo because it spools to fast. I had that problem on my celica tricking the engine into thinking I'm spinning the tires and then lowering the rev limiter. That was quite annoying.

Is that a concern here or is a lighter flywhee and tt's a go?

 

Consider RPS Sport and Max series clutches and the RPS Cyn-R-G flywheel which is not as light as JWT but has shown to be less prone to warpage

 

The twin ATS carbon is only $1990 with flywheel..shipped...FYI.

RPS makes very good clutches/flywheel..we sell them too. The one I prefer, which I sold to Anthony, is the RPS segmented billet aluminum flywheel (18lb), and Sport Clutch with street disc.

I havent added it to my website yet, but the price is $900 for both. Rated to 500trq but probably a bit more than that.

The other option, if you just want a clutch..no flywheel..is a good Clutchmaster Stage III or Stage IV.

Regarding the lightened flywheel, and effects on turbo...IMHO...I didnt notice a bit of difference with the lightened flywheel in terms of spool up. I am building 12psi of boost at just 3000rpm, and on the street, I didnt notice any increase in lag.

Maybe Ernie can comment on his perception of the lag. Lag is something you dont see on the dyno..but I will say that the boost pressure builds very rapidly...even with the big Greddy turbos.

Hope that helps!

 

good info, thanks

 

whatever should be installing the Cyn-R-G flywheel and Max 6 puck clutch on monday. Maybe he will post his impressions although the Max 6 puck is overkill for a stock motor + APS kit.

 

And hopefully, I'll get that injector in tomorrow morning and everything will be running, then i'll dyno on saturday with ernie and i'll let you know my perception of the lag, or lack there of...."lack of lag"--hmmm sounds like an 80's glam rock band

 

I dont think any clutch is overkilll for F/I applications. Sure, if you daily drive the thing, and never take it to the track, then even a stock clutch would be fine. But the first time you try to slip that clutch during a drag start, it will instantly overheat.

Also factor in longevity, as the carbon multi plate clutches last much much longer than traditional single plate organic or metallic-combo clutches. Given the $500-$600 in labor to install a clutch on the 350Z...this is something that I dont want to change very often.

And carbon disc actually grab better as they get warmer...its the best of all worlds. Increased longevity, stock pedal and engagement, and increased grab as the discs heat up. Not to mentioned they can hold 700-1400whp, without any increase in pedal pressure (unless you go with the heavier pressure plate).

 

Agreed, carbon disc clutches are the ideal way to go, but they are pricey. Russell has a carbon/carbon clutch on his 1000+rwhp car and he can slip it all day long with no problems.

Depending on driving style organic and metalic clutches can last for years. Ive had an organic on my 530rwhp Z32 for two years and it has not given me any trouble, BUT I don't beat on my cars and I have never taken it to the drag strip so that probably helps.
