So just had the 2.1 motor built and took it to Cecil county drag way in md. Def didnt do as good as I wanted but o well next time. First time down the track was my best time and best mph. Launch control was to low for the Hoosiers on 26" qtp so it fell on its face bad with a 2.137 60' (horrible I no) haha. Ended up going thru the trap at 11.5@138.61 on rev limiter a good ways before the end of the 1320. We turned up the launch control and the rev limiter and very next run the exedy twin with prob 1500 miles on started slipping so bad I let out and went 13.9@67mph lol. Time to get a quartermaster and actually be able to launch it. Just sucks I wasted that much money on a clutch people praise so much.

Really need a quartermaster just funds aren't there after motor build haha.

 

Planning on running either super99 or 6766 in spring with a stm ff manifold, quartermaster 8 leg, and see if I can skip 10's all together and make that 9 sec pass I want lol!!

 

my exedy twin hd had about 2k mileson it and lasted about 5 or 6 highway pulls @ 773whp and 663wtq 42psi haha

i was going to install an exedy triple but i just dont no anymore been hearing bad things about it, can a quartermaster 8 leg hold more tq then a triple disc?

 

People are using the quartermaster to go into the 8's. every person I no except one I have talked to hated the exedy triple they had real bad lockout issues which also caused trans issues. To where they say you don't wanna dd on quartermaster but holds great power and shifts like a champ at high rpms. I have a civic for dd the evo is pretty much turning into a dedicated race car!

 

I must be the only one that still believes in exedy. I go 10.6@138 on my twin exedy and only had one slip issue which was because of my fork stop being to close. I launch 6800rpm on my Hoosiers and gonna bung it to 7200 on the next outting. OP if I was u I would take a look at the fork stop if u have one cause if it's too close it will not allow the clutch to expand as it beast up leading to a slip condition.

 

I don't even have a fork stop so it should be releasing all the way. It just wouldn't hold. One of my friends posted a video on Facebook of it and the whole way down the track you just hear the clutch slipping.

 

With a 500hp car that mostly sees street use I think the exedy twin is a great clutch it's smooth and all. Just feel for a high horsepower car it's a complete waste of money I mean it was like me just donating my money but can't write it off and 8 hrs of my time. It had 3 launches on it and less then 1500 miles and was slipping all the way down the track.

 

If your guys' clutchs are going out after those little of miles they were not adjusted/installed correctly. That's really what it comes down to. A triple will hold the power and is very streetable, but I've heard nothing but good things from the new QM.

 

I hate to say but these clutches really can't be put in wrong! And it drives fine before and after the track but to launch it with that much tourqe and run it all the way down the 1320 it slips. When I left there after it cooled down rolling 1-4 it didn't slip. But a preped track with Hoosiers at 12psi clutch just wouldn't hold.

 

I really don't street this car and everyone I've talked to with a triple hates um cause of the lock out. I may at the most put 2000 street miles on this car a year

 

when i had an exedy triple it shifted great...the issue the exedy triple has become notorious for is stripping hubs though...that being said my buddy just switched from a comp twin to the qm 8 leg and absolutely loves it...i def see one in my future

 

They redesigned the triple a while ago, and most people who were strippimg hubs was because the slave cyl. And clutch pedal wasnt adjusted right for the clutch.

when I say it was installed incorrectly, I am mostly talking about how the slave cyl. is setup for the clutch. Ive seen a local guy get 20k out of his running 9s a ton of times. Its very doable if its setup/installed/driven correctly.

your car should run low 10's with that mph, good luck

 

I run a exedy triple. Has about 1k miles on it and a track day. Ive had no issues so far.

 

No fork stop, so this will soon tur into a my ring keeps popping out
thread. With that power and obviuosly you race the car, I think you may want
to invest the 50$ and get a fork stop. As far as your clutch goes, im not
sure about whats goiing on with it but as i stated my car has the same
clutch making 685hp,520tq and stops the earth from rotating when I leave out
of the whole. No slipping all grabbing. But if your clutch is going out and
you are going to upgrade then I do suggest the QM.

 

Yea I'm def getting a quarter master this winter just got to bank some money after the motor build I just did. While its down for that I'm doing a forward facing manifold 6766 or super 99 turbo clutch and if all goes well a ultimate ratio trans. Cause it still has evo 9 4th in it. I was prob a good 50' from the trap when I started hitting rev limiter at the end. We just retuned it the day before the track and with the hoosier the 2step wasn't high enough to come out. So we turned that up and the rev limiter and got down to a 1.8 60' but had to feather the gas with the clutch slipping down the track. It holds fine from a roll in the street but to go wide open from launch to finish on preped surface on the qtp the clutch was the weak link.
