does anyone know how much HP the ACT 4 puck clutch can hold if used with a stock pressure plate?

 

just go with the 6 puck you'll hate the 4 puck it chatters like a mother

 

I dont care about the chatter, just the holding power. I had a 3 puck, and i loved it.

 

use the 4 puck and an itr pp and you'll love the combination. it's a bit extreme for the street if you use the xtreme pp with the 4 puck, but i used it everyday, just depends on what you're used to.

 

6 puck will chatter much more than 4 puck.

I use the 4 puck with extreme pp. almost no chatter, but moving around on gravel
can get annoying.

 

The least amount of surface area that the clutch has with the flywheel and the pressure plate will create more holding power, depending on what the buttons are made of. Usually the one with the least amount will be the most violent, example squeeling, chatter..... I had a 4 puck with copper buttons and it felt like my teeth were gonna fall out of my head when I would engage that bitch. I never once had a clean take off with it while driving on the street. I would never put a solid drive plate 4 button clutch in my daily driver again. With the 6 puck I have now I am able to race at the track with slicks and not have the clutch slip and it is bareable for driving on the streets.

 

EVO, which pressure plate were you running with the 4 puck?
