For some reason IIRC it won’t work in the pull style (factory FD) clutch? Is this true or am I making up memories?
As much as I love dropping the tranny, the scattershield, makes it a more painful to get it done quick. And since the re-Pucking i just had done, slips like crazy on a speed shift, its either get another real ACT disk, or upgrade...Figure if I’m going in there again lets do it right-er lol

 

Love my sintered disk. Also have some act 6 pucks new that iwill never use if interested.

 

Sk8world, you finally found something to hold? Details?

 

Ram? 1-23 240 mm?

 

Custom ACT.





Ended up just buying one of Ari's disk's. You can get one made but they are almost $500 for the disk. I looked at the ram and spoke to them. Reason I decided to go ACT was disk thickness. Now you can shim the RAM until you get it right but I would rather pay the $350 differance than pull the tranny a few times trying to get the shims right.

BTW ACT is a great company! AAA+ for them!

I have sent back a few disk's that they no charged repucked for me and my last combo (Extreme plate and 6 puck disk) they replaced with new items when the disk failed. Grant it it failed pretty quick but I just think the rpms hitting off the line over comes the ratings of the clamp load. I dont blame there product being bad. I will continue to support them 100%!

 

Anybody want to order one PM me for the part #. Will take them a week or 2 to produce.

 

What's the thickness difference of the ram to the act?

 

dont remember off the top off my head but it was thicker so shims would be needed.
Thinking the RAM is .380 and stock specs are .280

 

Gonna be a PIA and ask if you can Mic' the total thickness, just want to see what im dealing with

 

Hold tight and let me go pull my tranny out to measure ...


It's the same as oem specs. The ram is thicker and might need to be shimmed to dissengage 100%. Wouldn't be very hard. I have heard of guys buying thicker disks, shim them and as the disk wears remove shims.

My goal is to go a year without touching a tranny.

 

LMAO, I meant one of the extra ACT disks silly lol
When i talked to ACT he told me street disks are .315 said he thinks race disks are a bit thinner, and to replace the disks when they hit .270
Since the ACT is a custom order, and the ram is less than half price.......... in theory would need a .065 shim which is a easy buy from Mcmaster, and placed on all the pins and under each clutch bolt should give me "correct positioning"

Is the ACT sintered a on/off deal? or is ther a bit of slip off the line?
the guy on the phone sounded scaared of them, like it was the harshish thing imaginable lol

He also told me pressure plates loose 200LBS of spring clampening in the first year, and that may be my culprit. but b4 i buy a pressure plate I might aswell change over to a T2 bellhousing, and then have the option of the XX prseeure plate, but then ill have to buy another scatter shield, exct.....
My new plan is to spend money once, eventually ill inact this plan lol

 

Its pretty damn hard on. There is a quick funny noise like a squeaky belt when I first engage it but its REAL quick. The shim deal should work fine but I was like you and ready to spend $$ to be done with the clutch deal. I spent a good bit of time researching differant setups. I was offered a partial sponsor ship from SPEC were I could have bought a mini setup for almost 50% off.
I talk with Ari Yallon pretty often end we discussed all the units and decided a sintered disk made more since and he ran 9.2's on it and lasted him over a year of racing. I like proven set ups, done being a test dummy. I leave that to guys with deep pockets!

 

bringing this back from the dead.
what are you guys using, still the act or ram sintered iron disk?
what is the part number for the act sintered iron disk?
thanks
justin

 

Act=500$ disk, made to order so 2 week lead time..
I went with new flywheel this season, and new pp, so I just got a new RAM disk to complete the deal, nothing wrong with my old one, just figured I'm spending enough what's another 200 just to keep my mind free and clear...
Ram=220$ at your door


RAM disk is .380, stock is .315, I added a .062 shim this go arround, on my well broken in PP I didn't use any shim and take up was at stock level... If you read enough about how the mcloud and other shimmed clutches are set up and shimmed its really not hard to figure out what you need, and since I only shim under the bolts, changing shims can be done via the inspection window without dropping the tranny... But since its all new math and visual setup of the disk are a easy first crack at it

Btw love the sintered disk.... It's badass

 

Thanks for the info bacon!!

 

I am still on my act. Just got home from driving the 7 and it's really not that bad once you get used to it. I am waiting on liberty to finish my damn tranny and start my second season on the same disk!

Bacon made more passes than me so the ram also seems to be holding well. Can't wait to hit the track, might just try it on my **** box, won't shift for crap! But at least I can see some mph.

 

I'm interested in the RAM disc.
What specs did you need to give RAM when ordering the disc?

Also what pressure plate are you using with it?

 

im probably missing the boat here but why the act over a twin plate? also are you guys makin scatter shields or does someone sell one?

 

Goopy makes a shield.

There are a few twin set ups that do the job but for the price of a sinterd iron disk that will work why not. They have gone low 9's in a few cars. Good enough for me.

 

I am pulling my CM twin and trying one of these.
Talked to Ari in great length about this.
One of my concerns is shifting with my stock TII tranny!

 

Is it stock syncro tranny? I can tell you that I wouldnt and haven't even bothered going to the track with my stock tranny in. Won't shift for crap with an iron disk. You have to wait for the rpm's to drop way back down. Also mr. 45 on here had the same issues and went back to the six puck.

 

meh! I guess I will just get the CM twin fixed.

 

I had ram make me a disc years ago. Def will not slip. Not really streetable though, was a real pain to drive. Still have it if anyones interested.

 

As Sk8 mentioned, don't waste your time trying to shift fast with a sintered iron disk and a stock synchro trans. It will not work. Soon as I put the 6 puck back in with a fresh trans this is what I got..
