I am putting my car back together over the next couple weeks.

I have noticed many guys are using the ATS Triple Disk now... has anyone actually had a problem with the twin disks at the HP levels we are currently making?

I am only planning to run 650rwhp for this year, and based on my experience in other automotive communities... that really isnt much to ask of a twin carbon clutch.

Whats with guys moving on to the triple disks already?

 

I think some have gone with the triple so they can run the softer pressure plate.

 

i'm guessing cause they're easier to drive than the twin maybe? otherwise I don't understand it either. Some people must just not tollerate a light clutch

 

I know of at least one person that went through a couple twins at the 700rwhp level and ended up having to get the triple.

 

Hey Charles. Nobody has really pushed the twin with the heavier pressure plate. Then twin with lighter pressure plate wont hold more than 550whp/trq for very long, unless its warmed up really well. I think the twin with the heavier PP that you have, should hold about 600-650whp/trq or very close to it. Make sure its nice and warm before launching/beating on it, and I bet you'll be fine.

If you were starting from scratch, I would recommend the triple disc with heavier pressure plate...its unstoppable.

 

aside from being capable of holding more power, the heavier pressure plate offer faster engagement vs the normal pressure plate for more response right?

Isn't the difference is just a spring or something?

I have the heavier pressure plate and it's way way eaiser to drive than my old tilton setup was, however I'm still not sure I'd feel comfortable handing the car over to grandma to drive because it does engage pretty quick. In slow traffic, you are never not aware of having a light clutch

 

I would get a twin with the standard compound discs, CCM coated PP and flywheel. The CCM adds alot more holding power.

The twin with the heavier 1350kg pp with the standard compound clutches will hold 900 flywheel hp without the CCM coating. The CCM coating will add another 25-45% holding capacity.

The twin is more than enough for that power.

The CCM coating claims to add about 10% additional holding power. When I installed my original twin disc with CCM coating, it didnt really help me much. Still started slipping at about 575whp or so...depending on the temperature of the discs.

The triple sticks like glue.

 

I love(ed) my Triple.

 

What compound discs do you have? The soft have pretty weak grip. The standards are great and aren't affected by the temp much. The R compound suck when they are cold, and pretty much useless unless they are hot.

I always use the standard compound.

 

I never had an issue with the twin plate...(at 615rwhp/575tq)... I thonk I may have accidentally received a heavier pressure plate when I go tmy clutch (not complaining)...the pedal feel was stiffer than others that had an 1100kg pp... maybe that was why it never slipped with repeated abuse

-TODD

 

The ATS twin and 1350kg pp is plenty for what you're looking to make to the wheels... The triple plate is ungodly. But if you want it to be bulletproof up through 800-900whp, then get it now. But if you already have the ATS twin with the heavier pp, then you're good to go. Although as mentioned, it is a bit firmer on the pedal feel...

 

How difficult is it to make the twin disc a triple disc. Surely it is not as simple as just adding another disc.

 

1 carbon disc, 1 more clutch plate, and a revised case. It's not cheap, unfortuantely. I think the last time I added up the costs, it was about $1400

 

Actually the cases are the same. The difference is in the pp. The 2 disc pp is just wider than the 3 disc. I converted a triple to a twin. The standard carbon discs are about $600 ea. The pp is about $250.

ops..you are correct. The case dimensions are the same. The PP is different.
