After a lot of trouble with the lock out issue and all the story about the ACT clutch problem I decided to do the Tranny rebuilt. This time a went with Turbo Trix which are my friends so that is why I went with them. After the rebuilt I put the Tranny on the car. Finally went to the track yesterday and ran two passes of 10.5@ 138 MPH on both passes. This was done with the ACT clutch and the amazing rebuilt this GUYS from Turbo Trix do on the tranny. For those who are having problem with the clutch there is a possibility that the problem is inside the tranny and not the clutch. That was my experiense so I'm chearing this with you guys.

Thanks to Turbo Trix, the gears went thru at 9000 RPM without a problem on both passes.

 

Several people had their trannies rebuilt, but still had the same problem. The problem gets fixed (at least temporarily) MOST of the time when adjusting the clutch rod out towards the end. Are you sure that when installing this rebuilt tranny that TT didn't adjust the clutch rod out so that it would work better?

Fwiw, I still haven't missed a shift since re-adjusting my clutch pedal, but I'm only running 12.0s and shifting in the low 7k rpm range. You shifting at 9k is impressive...

 

I lived in Puerto Rico so I took the tranny of the car put in on two boxes, took a plane went to TTrix, made the rebuilt and came back. I put the tranny back on the car and the adjusment wasn't touched.

 

I thought the problem only existed on the street disk ACT? Are we sure that JVELA is running the street disk into the 10s? Can that clutch even get an Evo into the 10s? I didn't think it had enough torque capacity befitting a motor capable of 10s.

 

The street disk has as good or better holding power than 6 puck, and is plenty capable of holding upwards of 700hp. Just dont' expect them to last as long as a carbon/carbon set-up.

 

Believe it or not, it is capable. The local 10-sec DSM guys here prefer the ACT 2600 (when it used to be a 2600) w/street disk. They burn through them in less time than people like me, but they just keep the PP and replace the disk while not breaking drivetrain parts as often. I was surprised as well when I asked what their clutch of choice would be on a 2g with 500whp. Almost unanimously, the answer was an ACT w/street disk.

 

Good information for those people looking for clutches, and good to know that the ACT clutch can handle the HP. My stock clutch went out around 12,000 miles. I was wondering how long my ACT will last? I have changed my driving style so that it should last longer.

 

I'm using the 6 puck.

 

The clutch life will vary mainly on how you launch your car and how often I ate one up in less than 3 months but I feather the hell out of the car to avoid detroying drivetrain parts/spinning the tires (Crappy tires dont hold anything). The DSM pressure plates are still 2600lb and the stock pressure plate for the Evos is right around 2600lbs I believe. Its been awhile since I cared to look but i think that is pretty accurate. I finally decided with a new setup (Mainly because the crappy throwout bearing stuff with our cars) so here is what I went with:

Clutch/Flywheel: http://www.thedrunken.com/gallery/ma...2_itemId=17797

Throwout bearing/Slave Cylinder: http://www.thedrunken.com/gallery/ma...2_itemId=17793

I will let you guys know how they work out. I really like the throwout bearing/slave cylinder thingy... No more worries about the fork and pivot ball like DSM guys have to deal with and no more throwout bearing disconnects like we have to worry about.

 

Trina,

I was looking at these and the $1700 Tiltons... please keep us updated on this!

JVELA,

sorry, back on topic...

 

The clutch specs are also very similair between the two. The only thing that makes me wonder about the tilton is that feeler guage thingy they include. There are a few versions of the throwout bearing, some require you to measure and space it correctly and the other one doesnt. That one seems to be the one you need to space correctly. Anyways, I will let you know how it works out.

I will tell you though if you dont like noisy stuff... this clutch may not be for you. I heard two cars with this clutch in it and they are very noisy Ill get a sound clip once I get it installed for you peoples. From the cars I heard, it sorta sounds like if you dump a bunch of nuts and bolts in the bellhousing and let them roll and band around.

 

That definitely rules it out for me then... I can stand a "little" noise, but not much as I'm in the quest for the "ultimate daily driver".

 

The more and more i hear about this clutch the more and more i fear that Something bad is going to happend when i get it and install it.

Did i make a bad choice?

 

If you bought the ACT clutch, then, no it wasn't a bad choice. Once you have it properlly adjusted you will be fine. Good luck.

 

How do you know the ACT wasn't the cause of your tranny problems? There are those that are saying the ACT and some other single discs are hard on the synchros.
