I think it's worth mentioning again that the Exedy twin HD served me perfectly under hundreds of hard launches, many back to back to back and I never had problems with shifting. My problems are likely because it's just flat tired of my abuse I still recommend this clutch, I'm just trying to see if there's anything I can do to help extend it's life, short of replacement/rebuild since it's holding the power fine, it's just notchy because it's dragging and I'm out of adjustment.

i originaly had an exedy twin but i kept popping off the t.o.b.i dropped the trans 4 times in 1 month so i went with a tilton twin and got screwed anyways.some people have great success with it,i for one have seen 2 cases personally and i know that the cars were not doing anything more than what the clutch is for.

yeah, I saw that the triple was doing well for you but I didn't know you had that many passes on it, that's very good. The tilton was also appealing because of the weight, it's amazing how small/light it is.

yes i did.i twisted them on mines.clutch only had approx.1k on it.i was making a little over 700hp but it was a few ocasion when i ran race gas.i mostly ran it on pump (511hp).my case might have been because of extreme conditions i guess even though thats what it is for but my brother in law ripped his splines clean with under 450hp and maybe 1500 miles on it.that was a huge surprise.when i talked to shepard about it he said he has heard of plenty of problems with the tilton with splines.i saw it 1st hand.it also damaged my input shaft.had to replace that too

what did tilton have to say about it?

Mellon, definitely remove the pill. Even on a stock clutch, this does wonders for making them last longer. The extended rod is a band-aid, but it might help a bit. I wouldn't plan on launching it/racing it a ton like that, mostly to just keep the car driveable until you can actually fix it.

When it comes to clutch, i havent really heard of Exedy Twin causing these problems... Well yea.. a select few but those clutches have been put thru so much abuse, id think itd be about time that it is getting lazy on you Mellon.
Best resolution IMHO... rebuild twin disk... Sell it... and put that money towards the Tilton... Push type clutchs are a thing of the past..

I've been thinking about this quite a bit, I'm going to install the Tilton later next week, that'll take care of the restrictor pill with the new braided line and I won't need to fiddle with the threaded rod.
I probably won't drive the car much this weekend and certainly won't be doing any racing so unless it gets much worse I won't mess with the pill/rod potential temp fixes.
I'll be sure to write a detailed account of the Tilton experience once I've got some seat time with it. It'll also be interesting to see if the e.t. , mph or dll dyno figures change with it.

There are three versions of tilton.
HYBRID- Cerametallic / Organic twin to 500-600tq
CERAM- Cerametallic / Cerametallic twin to 600-740tq
CARBON- Carbon/ Carbon twin tp 940 tq+
Tilton ceram and hybrids used to have softer hubs. They are now made out of a darker hub that has been hardened. In some cases of harmonics, the hubs can still rattle on the inputshaft to the point of wearing them down.
#1 the tiltons are all UNSPRUNG.
#2 the tiltons all have hub contact patches smaller and more narrow than EXEDY and ACT.
#3 this allows axial and side to movement from harmonics and imperfect input shaft alignment and "true"
#4 these harmonics can transfer to the hub splines and accelerate wear between teeth and splines.
#5 the tilton carbon carbon is not designed the same as the ceram and hybrid units as the hub spins BOTH discs at once with more material contacting the inputshaft. The cheaper twins are individually responsible for each hub spinning the input shaft on their own.
#6 The tiltons are lighter and between the weight and disc chatter on the input shaft, you will transmit all of these harmonics to the knock sensor and waste the next year with the clutch ruining the performance of your stock ECU Evo. P0300 is your friend.
There is your information as well as your forewarning. If you want to press forward with your car on the stock ECU. The tilton ceram or hybrid is NOT the clutch for you.

Mellon I'm having the same problem as you and this weekend when I get the rest of my motor out (blew up on me a few weeks back) I'll try to figure out wtf is wrong with my twin and thinking about rebuilding it too depending on whats wrong. I love the damn thing but not with the problems I'm having, you can put it in reverse and turn on the car and it starts moving..yes the pedal has been adjusted out a thousand times anymore the rod is going to fall out of pedal. So I'm going to throw in the longblock and then next focuz on fixing the clutch because it just drives me nuts not being able to get into gears.
You've got that right lol P0300 has been popping on my car since I put my clutch in last year

thanks for the feedback TTP, I have the CARBON- Carbon/ Carbon twin tp 940 tq+ for what it's worth. I intend on running the stock ecu with the new setup, but I do have an AEM EMS sitting here ready to go in. I just want to see how far I can go on the stock ecu/mas first.
