Your clutch wasn't holding but you exploded your transmission and diff? Than you switched to a clutch that is rated for less TQ?

You really trying to tell me that a twin disc that's rated for over 600wtq is better than a single disc rated for the same amount?

I beg to differ...

I agree with Juan about a more gradual torque curve. You'll still have plenty and probably make better use of it. More linear to progressive vs spike and fall!

So Nate, Jr and Lance agree that the tune is good and we just ran a 10.4 on a slipping clutch, short shifting...

You want us to change the tune?

Naw, I'd just keep breaking ****.........I'm being a richard cranium again

I'd defer to the experts you mentioned and find and fix the weak link. Trouble is another will develop somewhere else. It's definitely a dilemma to think through though!!

Haha no hig deal!

Finding the weak links is exactly what we are doing and upgrading accordingly lol

Axle breaks... replace with dss stg 5 axles
Differential breaks... replace with cusco
Clutch breaks... replace with triple disc

Or build in some give/ slip in the drive line, like the tires or maybe a just a tad less early torque, just saying!

Junior and I were talking about running just rear drag radials, matching diameters of front and rear and seeing if you could get it to leave more like a RWD, maybe dial your DCCD to the rear.

What happens if the engine breaks?
What happens if the turbo breaks?
What happens if the axle breaks?

Everything is costly when it comes to modifying these cars and it sucks but in order to play, you got to pay...

Exactly!

Some people like to buy drinks, I prefer engine and tranny fluid if possible...

Some people like to smoke, I much rather prefer smoking tires and clutches!

My grandfather helped buy this car for me and he loved it as much as me while he was living and now that he is gone, this build is dedicated to him and I will not stop until I hit a 9 in his honor!

Cool...car is most likely making over 700 dyno jet.....did you notice a difference with the bomba Tb? Dont think a 11^ sti made it in the 9s yet would be great if you become the 1st

Yea, first 11+ sedan in the 9s is our goal and definitely possible based on the results from the shakedown passes from Thursday night so we shall see when it's back together!

Yea it should make very close to 700 on a dynojet. I dont know about over that but I can always dream lol

As far as the tb, I can exactly say I have l "felt" a difference but it showed on the dyno graph!

Where'd you do your math or find your torque holding capacities? 430tq for exedy twin and 725 for ACT.

Have fun smoking your twin.

Well, I'm doing the triple disc that is rated to 776wtq and the twin disc that I was going to use is at least rated to 535?

I thought the heavy duty twin was rated to over 600 but after taking to Josh @ IIR, I changed to the triple!

I have smoked two 6 puck discs already, with this most recent one only lasting about 8k so please tell me more about a clutch actually withstanding the amount of torque that the company states on their website...

Even if I did buy the twin and that wasn't enough, I would just build it into a triple which was my initial plan

Drivetrain upgrades start tomorrow in the quest to run 9's!
I just got a chance to watch your video and if you listen closely there is no engine tone change even in the higher gears---your clutch was not slipping and if it was it was very minimal.You are going to have to pick up a few more mph and tenths in the 1/8th to go in the nines.I hope you do it but the way the car sits it probably won't.

It slipped at the 3rd and 4th gear...

The way the car felt and the way my clutch looks beg to differ with you thinking that the clutch was not slipping lol

without a log its hard to say but think about it this way at the power level you are at and the load is the highest in 4th the engine would have went into the rev limiter if it was slipping that bad ---been there done that.Like I said I hope you do hit 9's.Also you would not believe how bad a clutch will look after a couple good hard launches from a high hp suby.

Nate put his laptop in the car for every run that evening and yes it did slip going straight to 8k rpm on the tach...

We are dropping off the tranny at AndrewTech on Thursday or Friday to get torn down, check out internals, also install the new diff and bellhousing!

The plan to install the tranny when it is finished, the clutch and if my wallet allows it, carbon drive shaft and stg 5 rear axles!

Slipping clutch, short shifting and 1.51 60"= 10.43 @ 132mph

Good clutch, shift @ 8k and 1.40 60" = 9.9X @ 140+/-mph

The clutch actually slipped on the no lift 2-3 and 3-4 shift, if you listen closely you can hear me shift, clutch slip, let out, then get back into it twice. You can see the lift off throttle in the log. Been there done that! lol

know what your saying hope you guys get it ready to go,you do know that dss has a 850whp axle set available now so you don't actually have to jump to the expensive stg 5 setup.
