Anyone know if this disc or equivalent is still available? I know Art sold his shop but Black Line doesn't appear to have retail sales via their website.

Looking for a street/strip disc coupled with a KEP 2 to hold well over 200ft lbs. and be able to slip on the street.

Blackline racing has them. There new disc is a gold disc just like the diamond back but not as aggresive. You have to call them and talk to justin.

Confirmed they have a new ceramic disc. Similar to the diamondback but softer in a sense that it's more "streetable." Said to be holding 300+ hp turbo setups.

HOWEVER, I bit the bullet early this morning before speaking with Black Line and ordered an RLR black magic disc.

Thanks

Dauz,
Let me know how it hooks up and how aggressive the disc is. I took my car out today and hit it hard for the first time after the cam swap. 1st hooks up, top of second starts to slip, wide open 3rd slips fully. Looks like im in the market for an rlr or diamond disc too. I do have a new copper head in my bin... Like to know whats going to hold my 22. Running a new kush and stg 1 atm.

I use the original diamondback with a stage 3 PP. It flat holds. My car would fry its 215x65x15 tires rolling into the throttle in 3rd gear at 60+mph with a spool. Engages nice and smooth too.

I'm betting the new one is built along the same lines.

Copperheads are great for highish strung NA cars. Don't waste your time if you are boosted and make 250ish, even with stage 2 PP.

Ok. The general layout I got set up is

Est 280 hp na on the race engine.
Proposed set up: stg 2 w/ either diamond back or rlr BM ok?

Turbo fi engine estimate 270
Proposed set up: stg 2 w/ rlr BM or diamondback ok? Hmm thinkbthe stg 1 will hold?

NA 2276 slips top of 2nd and full wot 3rd. Est 190-200hp. Think the copperhead would be a good candidate?

Thanks for the intel ahead of time.

According to rlr. Bm disc works best with stg 1 up to 400hp. Or go with what chip said , stg 3 and blackline racing diamondback or gold disc and be done never go back

Really? Where is it that they mention stage 1?

I have the Berg Super Street disc with a KEP stage 11. It will chirp the tires going from third to forth in my Turbo, FI Ghia.

Ok read the other post that Seth did few back. Looks like John and Eric is running the copperhead and stage 1. Ill try that next time. Now is to build motivation to drop my engine...

Doh, I was in Ewa a few weeks ago. Although I was busy helping my pops out with various things. Will be back in April.

I thought the KEP stage 1 couldn't hold more than 200ft. lbs.

Eric is definitely NOT running the copperhead in his turbo car. REV6 twin disc if i remember right.

Aww too bad. I dont think im over 200 torque though. Hell with my set up id be surprised if I have 180.

Yea im running NA. Do you suggest not running the stg 1 and copperhead for my set up? The stg 1 and kush held my fk8 combo. But it Wont hold on the 86c.

I called and talked to ron about it. The sintered iron disc is designed to increase friction with heat which means you don't need a lot of clamp load to hold the power.

Stg 1 pp hold 180ftlbs with a stock disc. Going to metallic surface disc increases 25%. Same applies to the other pressure plates. Clamp load helps a lot. Most modern day cars have a higher clamp load on pp but also have hydraulic clutches so no need to worry about an aggressive disc.

I think Chip B. did mention on several occasions (not in this particular thread) that his Stage 2 + copperhead combo started to slip at 250hp. I'm assuming he almost had matching torque. I had the same combo in my IDA'd 78x92 with ultra mags and 9.5:1 compression and it drove and held GREAT. I honestly don't think you'd go wrong with the copperhead in NA. However, PP may be up for discussion.. or at least I can't speak on it. I've never had any experiences with a stage 1. Only a three finger 2300lb which broke my bugpack HD clutch arm and all stage 2s.

I'm shooting for the best driveable combo which will hold up to a turbo boosted setup while also occasionally dialed up on race gas. So 250-290ish torque range is my workable area.

Sintered Iron clutch discs are very heavy compared to conventional discs...
If you run synchro's in your transmission don't plan on shifting FAST as you will potato chip your synchro's in no time the inertia from the heavy disc causes the synchro ring to do a lot of extra work in slowing the gears down for a shift ( been there done that seen others do it as well, the bent synchro's that is..)
If you have a pro ring synchro-less transmission setup you will be fine.

I have had a copperhead disc in my car since 2007, with a stage 2, 1950 lbs
N/A with a 50 Shot, The clutch disc is not harsh in the launch and gives just enough as to not break parts...1.58 60 foot and 11.60's no signs of slipping in 3rd or 4th under full power (and no bent synchros) These are a great street disc.

If Ron is telling you this, then this means I am past 180tq. Looks like I better just be safe and put in the stg 2 also.

Stage 1 and a dual friction disc will hold for the street with street tires . Friend has it in his 2180 na (ported heads, cam, 48 idf) holds perfect

Stag 2 and dual friction will hold a 2332 turbo up to 8-10 psi (Jason D started smoking his clutch after those levels on the dyno)

Stg 3 and diamondback/gold disc from blackline or stg 1 and rlr black magic will hold whatever you got unless you go past 400.
