I have an existing act 6 puck that is dragging (first gear, clutch pedal all the way down step on gas rev to 6krpm and car starts moving forward by itself)
Goals are no more than 600 mustang dyno whp. Realistically closer to 500whp, currently on a built 2.0L but might do a 2.3 in the future.
Currently driving around with 434mdwhp.


With the monoloc collar being available it's hard to ignore the ACT
Organic clutch material
565ft/lbs
full face which i dont mind, i HATE the way puck discs shock the drive train.

Exedy twin SD is cerametallic has a lower torque rating of 430...
Would the HD be much worse for the street compared to the ACT?
I am guessing it's a smaller engagement point where as the ACT will just give you a bigger left leg muscle, but allow for better engagement?
Will the HD shock the drive train more than the SD like a puck vs a full face?

Im running the twin exedy HD. Also, the monoloc does fit the exedy. You do not need the ACT to run the ACT monoloc. I dont think its worse on the street. Its just noisy with the clutch pressed.

Engagement is a little sooner but, in my opinion, its feels better when engaging. I drive it daily and its not hard on your leg.

Depending on how you launch it and drive it, any clutch will shock the drivetrain. It is a smoother engagement so for daily driving, less shocking if thats what your getting at.

I went from the same clutch (ACT 6 puck HD) to the exedy. It is more expensive but can take more abuse. New discs run about 230 each. I prefer the exedy until ACT comes out with a twin disc.

 

Really am not digging how the average person gets less than 20k miles out of the exedy twin. Think i'm going with the ACT.
