Re: Slipping Clutch/ Contamination Issue
Started turning the boost up and it's now slipping pretty bad in 3rd. I want to do this clutch job this winter but want to know some things before I begin so I can do this once and for all and be done with it slipping. This is the 4th? clutch i've been through that wont hold any power. I have a ACT 2600 with street disc and ACT streetlite flywheel. No more contamination going on, it's all dry in there.
Flywheel has been stepped to .610 by Proven Force every time it's been replaced. New disc every time and have tried 2 pressure plates.
I've read you shouldn't resurface a flywheel that many times.
So i'm looking to get a new disc and flywheel.
Any suggestions?
Thanks, Mark

Re: Slipping Clutch/ Contamination Issue
Sounds like a solid plan, but that is a lot of disks to be blowing through. How many were because of contamination? What are you doing to break them in? Have you checked the pressure plate for any warpage?

Re: Slipping Clutch/ Contamination Issue
The last 2 or 3 I can't really remember were because of contamination, Pressure plate was flat with a straight edge and I sanded it prior to install.

Re: Slipping Clutch/ Contamination Issue
I'd say twin disk. It will cost more but the long run its worth it.

Re: Slipping Clutch/ Contamination Issue
A 2600 should be plenty for 20g power. I think that's a good plan to just pick-up all new clutch/flywheel components (don't reused the contaminated stuff) and start fresh.
Make sure if you're buying an ACT clutch, you get a new PP and disc. They switched designs several years ago, you don't want to end up with a mismatched PP and disc from different designs.

Re: Slipping Clutch/ Contamination Issue
Don't want to go twin disc as it's totally unnecessary for my power goals right now and I do eventually plan to go AWD.
What did they change? I know the disc went from 6 to 4 springs, but did they also do something to the PP or flywheel? Both my pressure plates have been used ones. One was the older part number and the one in it now is the newer part number. They had low miles, but were used none the less.
I'm really starting to think it's the flywheel being resurfaced too many times (i'm sure the previous owner had resurfaced it at least once) now there is not enough material? But I thought that pedal adjustment and shimming would make up for that?

I don't know the specifics of what they changed, but I know they changed. I personally had a dragging issue with my mismatched setup. Just make sure if you're running an ACT clutch setup, that you have matching components.

Re: Slipping Clutch/ Contamination Issue
Will do. Thanks for that tip! I think i'm just going to spend the money and get an all new setup. Do you think I should stick with ACT or go a different route?

Re: Slipping Clutch/ Contamination Issue
Break-in for the disc was at least 300 miles of mostly city driving some hwy, lots of disengagement and engagement and every once in a while a couple pounds of boost but not more than 5.

Re: Slipping Clutch/ Contamination Issue
For your power levels there are a ton of different options. If I was in your shoes, I'd likely go with ACT2600/street disc. In the past I only ran stock flywheels. Today, for the right price I'd consider an aftermarket one with replacement surfaces, but I'd find the heaviest one out there. I like the idea of just buying replacement surfaces rather than sending the stocker to a machine shop for a couple days hoping they get the step right.

As did I. I would also recommend match components.
While mine was the 2900 (with 7lb Fidanza FW) rather than the 2600, the thing would never slip regardless of the abuse. I've done full disc with springs, sprung 6 puck, unsprung 6, and chewed though 3x 4-pucks at about the 450 TQ level and it always held and held.
I even had to launch in 5th gear all the way from South Minneapolis down to Prior Lake because the gearbox grenaded and that was the only gear left to choose. Still held without slipping!
Sucks you're having such shit luck with you setup.

Re: Slipping Clutch/ Contamination Issue
I ran a couple different competition clutches with a fidanza light wweight flywheel in my old talon and had good luck with them
