im looking into a hd pressure plate and 6 puck sprung act clutch kit for my fc . im getting a deal on it but i want to make sure it can hold up for my power goal of 400whp -450whp . car will only see drag / and highway . im not sure if i wanna get the extreme pressure plate to drive it around . i ahd a act street disk / hd plate on my bnr stg 4 set up . i loved it never sliped once no matter how many beatings i gave it. let me know if any one else is running act 6 puck on thier fcs . thanks

 

I am running one on one of my 7's, but I have not tested it hard yet, it's going on the dyno tomorrow night though so we will see how she does after that

 

You'll be fine. I have the same clutch on a stock flywheel and I'm pushing 810 to the wheels. It has over 6000 miles of being beat (putting a new disc in since its finally starting to let go, going with the same 6 puck). I also have over 60 dyno runs between a mustang dyno (Steve Kans at PRT Performace & a dyno jet).

Also, I run Nitto 555R on back measuring 305/35R18's and a Kazz 1.5 way diff. No issues and these tires hook.

Only problem I have is breaking stock transmissions, more specifically I shear third gear completely. That's the gear I mainly use to run people in, have yet to use 4th gear for a run besides on the dyno.

 

Yes, I have run the Sprung 6 puck and HD pressure plate for many many years on my FC with BNR Stage 4. I put down 340rwhp @12psi boost and then 380rwhp@14psi and the clutch was holding fine when I was running 17psi boost (over 400rwhp).

I am very abusive with it- lots of 2-3-4 flat shifts against the rev limiter.

275/40-17 NT01 tires.

3rd gear eventually went in the transmission after some roll on wheel spin/hook back up, but the clutch was fine.

I did try 5k rpm 2nd gear clutch dumps for launches a couple times because it had no traction in 1st, but it did slip doing this down to 3k rpm and grabbed again.

Only complaint I had with it is the engagement is fairly abrupt, so it is hard to get really smooth starts without revving the engine up a bit (so when trying to be quiet and subtle like).

And if you do slip it a lot (like 2nd gear launches) it will really put heat into the pressure plate friction surface.

I put a Exedy sprung twin plate in my FD and it is a bit more refined. I would guess its because of more friction surface and less pressure plate force.

I say go with a quality full diameter sprung twin disk for the street if you can afford it.

 

the disk should hold up i was more worrired about the pp . as long as it last from next month till october ill be happy .

 

What you want (act hd pp and 6-puck) is what Steve recommended to me and I purchased. I believe we have similar builds.

 

well i got a way bigger turbo lol no more bnr4 . ill try it anyways

 

Speaking as an N/A person, I'm having a lot of trouble with breaking the clutch fork pivot ball, and the clutch fork after reinforcing that, with ACT pressure plates. When it first happened, the hits I got were mostly for Turbo II guys.

 

I think the problem with TII guys breaking clutch fork pivot ***** is with the extreme pressure plate and exxxtreme pressure plate or however they call them.

I just replaced my clutch fork and pivot and front cover when I put the the clutch in and again when I replaced the disk as a precaution with the HD.
