What is the difference between the act 2900 clutch with a 6 puck disk vs a 4 puck disk. Does one grab harder. I thought the 6 puck was pretty much race only. Which would be best for a daily driver?
Thanks

Non puck, and even better yet, a 2600, unless you are going for 600whp on a daily driven vehicle...in which case, we all know it wont be daily driven for long.

i was gonna say something, but then cvd chimed in like an ass and talked all good.......and stuffs.....garr

two pucks ;) (the difference that is)

Glad to be of help, let me know if there are any other math problems you are having trouble with.

which 2900 disk would be easiest to drive around town with. I thought there was a street disk, but I guess not. I was told there was only a 6 and 4 puck.

They both suck for street driving. But get the 4 puck if you must get one :goodluck: on having anything in one piece.









I must say that that is horrible advise and you should not get a pucked disc. There is a reason they don't offer the 2900 with the street disc, cause you don't really need a 2900 if your getting a street disc.

what could hold a lot of power that is streetable?

A puck clutch disc with a sprung hub is not as bad on the driveline. More pucks is not always better. I have a ClutchMasters 2500 with a 4 puck sprung hub and I like it. And it's good to 600+hp.

The 2600. It will be fine for 500whp or less. To much more than 500 and you are starting to push the limits of the clutch.

One major reason the ACT pucked discs are something to avoid is the lack of springs and they are on the agressive side of things. (really bite into the PP an FW).

CVD gives good advice.

an act 2600 with street disc. an act 2900 can also be used with a street disc, but you won't need it. puck discs, both sprung and unsprung hub, will give a lot of additional driveline noise, particularly when coasting, the engagement will also be more harsh, less forgiving. you don't need a puck disc. i believe even shephard runs a 2900lb+ pressure plate with a full face disc.

Shep runs a 3200lb plate and a full face street disk, rau in his awd ran a 3200lb plate and a 6puck disk. Just get a 2600 untill it starts slipping all the time, then look into a sprung pucked disk of somekind. My 2600 holds 530whp fine untill 5th gear.

Yeah, they do offer a 2900 with a street disk. I have one sitting in the garage. I am with the rest of the guys though, get a 2600 with the street disk. I doubt you will be making more than 500 whp, so it will work just fine for you. Why put more stress on the driveline than you have to?

A 4 puck disc will grab/hold more than a 6 puck.Less surface area with the same pressure=more friction.

That is what he is worried about. He should have quite a bit of power when all is said and done. He wants to put one clutch in there and be done with it. Not have one that slips (at all). He is going to be starting with the same turbo you have John. Then he plans on swapping to a larger one.

Seeing that John's clutch (2600) slips in high gear, what would be the next step up then? In ACT, isn't it the 2900?

If he needs that much holding power then it would be wise to go with a better friction material like ceramic. Just get a sprung hub.

Just get a 2600. He won't need more. :secret:

I agree. It is going to take him a while before he makes that kind of power. He is going to be breaking tranny parts before he gets to 500 whp anyway, unless he puts in a built tranny. So the clutch is going to have to come off anyway. People think they can just throw some parts on and make 500 whp, it doesn't work that way.

You can somewhat just throw some parts on and make 500whp, but to actually get that 500whp to run a 10 without breaking crap is the hard part.

Well said, that's why my tranny is at TRE right now. I don't want to take any chances and am having it done now before it breaks and trashes the trans. :3gears:
