A Centerforce DFX clutch wont handle a cammed 6.0 with a 150 shot...


Went 7.2 1/8th at 95 on motor with the super vic, no 4 hols spacer like the Jr had, and 2 steps colder of a plug.

On the 150, the best was 7.0 at 101! LOL, 6 MPH and 2 tenths, pretty sad, the clutch is just not capable of getting it done!

 

Thats great to know seeing I have the same clutch but for my tremec 5 speed. Im going to go kill myself ill brb. lol What is a good clutch people are running that is somewhat streetable but can handle a ton of power?

 

Well, you can go to ls1tech.com and go to the manual trans section and look at the fastest 6 speed section to see what clutches they are using.

 

well, you could go to google and search how to read a spark plug instead of asking a million questions in here but you dont.... just saying those who live in glass houses

 

Dude, you may have misread his intentions. I don't think he was trying to be smart about it. Just saying.

LS1tech would be the place to find good manual trans info.

 

Maybe I did take it the wrong way but if I ask a question on this forum I was looking for an answer instead of "look at ls1tech". I come here often and I have never gone to that site so why would I go there for answers when plenty of people on this site have 5 speeds that make big power? Any questions that are asked on this site could almost all be answered over at ls1tech or another site so I dont really see how his comment was helpful. Also jusy by looking at what those guys run in there 6 speeds might not be the same scenario for a 5 speed or just because they make big power doesnt mean there street freindly. I apologize if I took the comment wrong but I still think it was not helpful at all.

 

My ZOOM D2 twin-disc, will hold over 1000 rwhp. No chatter, and with the concentric slave, has a light pedel as well.

 

Lol, no man, I am just using my iPhone and it is a PITA to go look and see what they are using and then cone back with it being on the slow 3G network, sorry.

 

How much do those cost?

 

more than braided fuel lines and fittings



....just sayin' dude

 

 

Really?

Damn, you guys get off my ballz, LOL.

Just wondering what a Zoom setup would run for general info purposes, i am not switching clutches unless mine takes a dump.

 

My Centerforce DFX and T56 were in an '03 Cobra that made 560 RWHP before I bought them. I believe his best was an 11.1X, now he's going twin turbo and automatic.

It's total clutch overkill for my GT though, I have to give it plenty of gas to take off smoothly. Seems like a real decent clutch to me, that's unfortunate that yours isn't taking a beating.

 

say hello to crappy driving clutches. im running a ram 9000 (i think thats what it is) and it did fine for me but never hit it with the nitrous at the track. this is the clutch with pucks on each side of the disk. im pulling it back out in favor of a stock clutch from a c6 Z06 so the car will drive a little better.

 

Im sorry for taking it the wrong way man. The internet can be a bitch to read something and understand where a person is coming from at times.

 

Its cool, i am sorry if i did seem to come off wrong.


I was wondering if i just got a clutch disc with the pucks if i swapped it out and see if it helps, and i am such a cheap *** that if the current disc burned up, i would go that route.

But, for tonight, since the nitrous tune is WAY better, 950 bottle pressure, 150 pill, the 500 RWHP Cobra that was on the race fuel tonight had ZERO chance, the GTO i also lined up with that made 585 RWHP got BANGED up, especially when we went to 4th and the H/C/I C5 vette got destroyed as well.

Good times, the one guy i was supposed to run for a bill said dig, 1/8th, and i know i need more to catch him, so i say 1/4, he says he only runs 1/8th, so i said fine, i only roll race so i guess it isnt happening, LOL.

 

^^^GW Hunter!!!

 

LOL, after looking at Tech, the DFX is about limited where i am at on power, so my assumptions are dead on.

 

Got this PM from the 500 RWHP Cobra:

 

What do you think your power range is for your setup?

 

I assume 500 fwhp and 650 on the gas, not to be exact but in that area, but the torque is probably over 700 on the button, just too much for the DFX clamping force.

 

Pro motion has some killer custom single disc set-ups that they spec per application. They use the typical spec/valeo PP with some crazy organic full-face disc. Two cars locally running north of 600rwhp and putting it to the pavement with that clutch handling it.

Other than that, time to go twin disc if you don't intend on having massive pedal pressure.

 

Well, I am really going to have to keep an eye out on prices to see what I am in for.

 

that bitch is getting it done zone, good job

 

Thanks man, surprised no one has really wised up yet, i sure as hell will not snitch on myself, LOL.

 

if it's on the internet they can find it zones....no way I'd be posting stuff like this if trying to hustle, but what do I know, I'm stuck in the 14s for the last decade

 

I'm running a McCleod dual disc street clutch for the street, and use a McCleod Soft Lok in the drag car.

dual disc with a new flywheel will totally kill a $1,000.oo bill, the Soft Lok will take care of two of them!!!

But, the dual disc has 5,000+ brutal street miles on it behind an NA 500 RWHP big block. The Soft Lok is an all out race clutch never intended for street use. Fully adjustable springs, arms, and counterweights and a multitude of disc materials available for either clutch.

Quality doesn't come cheap. Once you get the big horse, big buck engine in the car it will search out all the weak links one by one and destroy them! But, think of it this way.....This country is slowly trying to climb out of a recession and you are certainly doing more then your share to get the money circulating and keep economic growth stimulated!!!

 

Yea, i know that goes for 1K, way too steep for me, been looking at spec 3 and 4s right now.



You need to realize, not everyone locally knows me, so it doesnt matter. Otherwise, it is just a matter of time before some find out, it isnt that big of a deal, just entertaining, i am not hustling like you and hiding my times and what not to be competitive like yourself. Maybe if i had a single digit 1/4 car, i would.

 

Your car moves out NA!!!!! Spec 3+ or Monster 3 would be my choice.

 

From what I see, those would do great for me, rolls out better on gas! Lol

 

How are you launching N/A? I've only had a few passes with my build and kept bogging off the line except for when I side stepped it managing a 1.87

I know my 3.08 gears aren't helping but I want to keep them since i'm going forced induction in the future.

 

Well, I had 2 mcleod twin disc clutches self destruct in my 4th gen (they replaced both of them, one just wouldn't hold, the other had the center hub crack and break).

I was actually surprised how long the stock clutch worked, I abused it hard, "drove" it out of the hole, occasionally with bunch of spray for something close to 180passes and a bunch of street time. I smoked it a few times before it totally died, and it would slip after that but started working again after it cooled off and I drove it around on the street some (I'm guessing knocking any glazing off of it).

I currently have a center force in it and I like that a lot more then the McLeod... it seems to grab and hold better then the stocker, but the centerforce tech guys repeatedly warned me onto to abuse it like I did the stocker, that it just wouldn't come back like the stocker did if I hurt it.

 

I rev to 6000 and come off the clutch, but the 4.30 gears are the advantage for em getting out of the beams.


I have heard of LS7 clutches holding pretty crazy power numbers, but the mcleod is out of my price range im sure, LOL.

 

Summit sell's them for a little over a grand depending on which clutch material used(organic, ceramic, cermetallic etc.). Shop around though, I paid less than half that.

 

I will see, i am broke and dont plan on replacing what i have yet since it still works great on the street, i see single discs doing the job and i will probably stick with that to keep price down.

 

Wow, a spec 5 for 485 i found, wish i was in the market with cash, it would be a bit overkill but for that price i think it would do the job.

Found the spec 3 for the same price, says it is capable of slightly over 800 FTLBS, so i think that is what i will get when the time is right.

 

I've seen spec clutches blow up horribly taking out the front of a T56, the bellhousing and a section of the floor...

 

Wel, true, but what clutches are used as much as spec? The more that are out there the more likely you will see people posting about them, very popular, i am sure any clutch can let go as they cannot all be perfect 100%, but i could be wrong.



Drug much *** tonight, GT500 with some bolt ons, Cobra, H/C/I vette, 2011 stang with some work, only death was a CBR1000 with some work done, got me by 2 cars or so, but i expected him to win.

 

The GTO finall posted it, but the first run was the 501 RWHP cobra and the filming car is a 585 RWHP GTO, the second run was me and the GTO, they both runs got the move.

I'm personally not a fan of the Spec clutches. We got all of 1 pass out of a 3+ in my buddy's 600rwhp street mustang. 1.52 60', then went a 1.54 on the next pass and the shift light never even shut-off on the 1-2 gear change.......smelt *very-much-badly* when he got back to the pits.....

 

How old was it? I am hearing the older specs were iffy and the newer ones have been revamped.

 

Was brand new last year when we killed it. It had street time for break-in, and 4-5 pulls on the dyno, went to the track and killed it on the 3rd hit. Car spun first pass, made a couple suspension tweaks, went a 1.5something 60 and wouldn't shift 4th, then went a 1.5something again and never caught the motor on the 1-2 change.

 

Wow, wonder if it has been happening allot? Gonna have to post on tech and see what they have to say.

 

Bottom 1.5 60fts @ roughly 3600lbs on a drag radial is obviously pretty tough on a clutch, especially a single disc. - I just wasn't impressed with the spec to not hold the power for being as heavy of pedal and as grabby as it was for street driving. The pro-motion custom that's in it now barely has more pedal effort than stock, engauges smooth, and holds the power.

The car is down right now for a good overhaul, I have a sneaking feeling it's gonna need more than a single disc when it comes back out. We threw down a 1.500 60' on the 275/50 mt radials just before he pulled it down, so I will find a 1.4something on the little 26" radials when it comes back out. - Not bad for a car that still gets 18-20mpg on the highway with the a/c on and the stereo jammin, especially with 281ci worth of 2-valve.

 

I think 87_TA on here was running a spec 3 or spec 3+ it lasted along while on his 406 with 150-175 shot. He's been 9.8's at 142 on that car with that clutch. Ask him to see if he really likes it but I think he does.

 

Well, the price of the spec makes me like it as well as results, this is from tech:


9.63 @ 144.91 - 1.397 - Spec 3+ -------- 383 ---- Nitrous 200 ------ 3350

9.92 @ 144.24 - 1.52 - Spec Stage 4 ----- 346 ---- Turbo ----------- 3750(60 would be better if lighter? LOL)

9.94 @ 138.00 - 1.30 - Spec Stage 3+ --- 364 ---- nitrous 200 shot -- 3450


This one is impressive with the mcleod single:

9.33 @ 142.XX - 1.32 - Mcleod Single ----- 388 ---- N/A -------------3180


Clearly they hold their own, but some just have better luck than others, i just want to be one with luck, LOL.

 

The 60fts tell me all those times were on slicks, not radials. - Since you're on the same, hopefully it will work for you.

 

Yea, i only run ET streets or slicks at the track if i have them.

 

I guess it just kinda peeves me that they rate it for "x" power, but the truth/fine print of that is only under certain conditions and stipulations.

Kinda like g-force's "600hp" T5's....
*must have 400+ tread wear tires, stock clutch, open diff, only to be used every 6th Wednesday of the month when the moon is full and Venus is in sight along with the aurora borealis in a 2500# or less car.

 

Hahahhaahaa, yea, dont you love the fine print.

Wondering when the input or output shaft in my trans is going to take a dump....
