I would say the new multi disk textralia. The single disk is rated for 700rwtq, and seems to hold more than that, so I would guess the multidisk should work even better.

What is the soft lock....

BTW: were talking 6500rpm launchs on 28in tires....I want something thats going to rip my head of when I launch..To be honest..I've tried alot of clutchs and the only one I've been saticefide with is RAM...I want somethin thats strip proven with this kind of power..

ram....i've had two rams go out on me both in around 1,000mi. i've had seven clutches and so far only the spec st3 + has lasted the longest.

good luck in finding one that lasts. You need a twin setup at a minimum. Something like the mccleod has held but you will be replacing the clutch annually at that power level. No one from what I can tell has found a street clutch that will hold that power on a hydrolic setup. If you are going to really be racing at the track you need to go auto.

Brian, shoot DJ'S 99SS and ask him...his car made 880 to the wheels in 110heat spinning the tires.

Yeah I would like to know this myself... I have worked with SPEC several times and i cannot get the clutch to engage and disengage fast enough during shifts... I have been looking at the texzilla and i have talked with Tim Tosto about his and we are both unhappy i know he runs a Ram... as far as launches i have had a few rev limitor dumps on mine with no problems its just shifting thats a bitch

The twin disk exoskel failed on DJs car quickly....They are now making him a TRIPLE-disk they promised will hold the power.

How is that dumb? You show me any 6m that cuts 60' times like an auto does consistantly and HOLDS and I will put that clutch in my car. If you are going to have a dedicated race car and are not willing to change your clutch every season your car will sit a long time. Clutches are wear items at the power level you want. And there is no "street" setup that is going to be simple to drive around town. I have destroyed my share of clutches and know from first hand experience that a strip clutch does not like the street or the constant heat the street puts into it.

And as far as the twin in it now it may just be shot. A single disk setup has not proven to hold more than 600 rwhp for any real length of time. We have many 500-600 rwhp cars here in central fl that have had good sucess with the mccleod twin setup but it will not last years. If you get two years out of one that is about as good as it gets.

This does not surprise me. With a triple disk setup it will be stupid expensive. It will probably be in the 1500-1600 range for the setup. I really wish that someone would figure out a way to go to a cable setup as many of the ford boys make stupid power and the clutch holds.

Mcleod Soft lock gets my vote

Thats what I had for one pass it slipped its ass off come to find out they say they sent me the wrong flywheel.


Also the spring cup broke 1700 dollars I wasn't very happy.

Do you have one of these in a 6spd car with stock hydraulics?

you guys are nuts for drag racing a 900 rwhp hydraulic clutch car lol

i tend to agree with pushin here. how many 1.3 60' t56 cars do we have that can do it over and over and over without pulling discs out constantly? sure we have a handful of guys that have pulled those kinds of 60' times but they are burning up clutches left and right. see all the examples in this post alone.

not saying it cant be done but obviously the faster stick cars aare getting tired of replacing these big dollar clutches and constantly being disappointed

lmfao!! calm down killla..I wanted to gather info on clutchs,not have my thread turn into a "mike(v6bird) make your realize how dumb you are thread..

I have a few f-bodys man and I'm fully aware of of what there capable of..
Alls I asked was which clutch will hold...I know a car will 60ft better (normally) with an auto..That doesn't mean if I'm going be running this car the 6 speed needs to come out.This is my dads "STREET" car...

BTW: the rear seal on the car was leaking so I'm thinking thats whythe cluch wasn't holding..I'm going to buy some disk and I'll decide if this exedy is really as big of a peice that I think it is..

Spec makes a dual now and it has had real good results with more power than you are looking to run.

We've had good results with the Mcleod twin disc. I do usually have it rebuilt every year, but I never expected slipping the clutch at 5k+rpm would lead to long life.

Depends on what your definition of hold is. Most twin disk applications will hold but not for any real length of tiime for 900rw hits. Asking a clutch to hold that much power on the street at this point with a hydrolic setup is more than any have proven to hold and stay reliable. It is going to take a triple disk application or a real leap in clutch disk material technology to make this much power practical to use on the street.

as far as V6bird aka mike, who cares.

Tilton Carbon/carbon.... some people here think you cant drag race them but Tiltions application guide has them listed as drag race/street clutch Their going to set you back 4500 bucks but speed costs money...If you really want to go fast you need to either get an auto or get a real manual tranmission

For a clutch to last only one year is just wrong. I really wish we could get someone to find a way to get one to last at least two years. I really think it will take a cable setup to get one to last more than a year for drag racing applications.

spec 3+ is holding good on my car at just over 500 on the spray but it shifts like ass. Trans was built by futral at the same time as 3+ went in and I have to force it into every gear swap where as I use to flick my wrist and hit the gears.

I am thinking of an auto when this clutch wheres out.

I think the material of the disk is the key. Something that is sintered iron, or a carbon metallic type puck style. But agreed as stated earlier with that much power multi disks($$$) or an auto will probably be the only solution.
