Broken ACT Pressure Plate

[Boosted Beluga]

Ok so I figured instead of starting a new thread id just bump this one.

I went to irwindale raceway tonight (1/8 mile) and on the 3rd run my clutch broke at the line. This time I couldn't drive it at all so I think the clutch disk or flywheel broke.

Symptoms:

Ps do you have pics of the disc material from the OP

[Boosted Beluga]

The pedal is stiff car goes in/out of gear fine but if I let the pedal out the car doesn't go anywhere or stall or anything.

No I dont I forget what they use.

^ I edited post...see above

ps that blows brotha. The most concerning pic of the OP is the pic of the pp friction side. IMO. The fact that it appears the disc material doesnt touch about 15mm or more of the ID of the PP and the fact that it appears much larger in OD than needed is quite concerning. If thats true I cant see the claims of torque holding capacity accurate as that is a lot of surface area that is calculated but not their in reality.

I tried looking for the material used for the disk but nothing. And if thats true then they need to redesign the whole thing to make it right.

[Tech/Sales@EM]

Well not only that...which is a major flaw. But look at the wear on the fingers. Quite Excessive for sure.

[Boosted Beluga]

Well I know they did redesign the PP and I got the "new" PP that was supost to fix the finger problem which sound like they did but now another weak point has come out.

anyone want to guess what I am about to say????


FUCK ACT!!!!!

[Boosted Beluga]

Lol yeah thats what I'm saying right now. 2x in 6 months

Maybe that 13psi tune wasn't such a bad idea.

[Boosted Beluga]

I know right lol well I talked to my mechanic this morning and he thinks I may have broke an axle.

[Tech/Sales@EM]

Yeah that should be the first thing you check is axle damage.

[Boosted Beluga]

Yeah I got home late last night and didn't want to deal with it. I'm going to check today when I get home.

[bcmurphy87]

broke axle would mean you definitively hook it up

[Boosted Beluga]

Yeah I was on street tires also lol launched at 2800.

[Ziggo]

I would be very surprised if you broke an axle on street tires.

[Boosted Beluga]

Me too but I'd be happy if I did.

[8.5MS3]

i do that at every red light

I second that, especially with a 2800RPM dump. Really not much slip with that at all, esp with a good pressure plate

[Boosted Beluga]

Ok I left work early and jacked the car up and found this





clutch works great so I called the shop where I bought the new axle (a month ago) and they are getting me a new one on Tuesday hopefully this wont happen again.

[Tech/Sales@EM]

Yah for cheap fix.

[qtrmile beast]

Dam beat me to this as i would have told you this... Good luck and get back to the track!!

[Boosted Beluga]

^^^ hahaha thanks and idk if im going to go back to the track. Im leaning torwords road racing now. I did manage to run a 9.3 at 76 tho and that was with a 60' of 2.4 lol that was my 2nd run. the 1st run I ran a 9.5 at 77 with a 60' of 2.2. My tune isnt perfect only running 15psi with it tappering to 13.5 by redline (Im trying to run 15 to redline) and AFRs are only 11.6 tappering to 11.4. Im sure I could get it to 9.1 or maybe even 9.0. with a 20psi tune 8.8 at 81 lol
