X2...lol

 

are you using the shanked bolts?

 

Maybe it's from those "john force" burnouts roy! :p

 

yes sir. all 3 of them.

And dustin shut your hole lol. I like my burnouts.

 

can i ask why you dont want to change axles? do you have upgraded axles but just not the halfshaft? i mean the only difference in the da and the rest is the seal on the tranny and the axle, so you would just have to buy 1 axle and an upgraded halfshaft right?

 

well, actually yes i have dss axles. and no that isnt the only difference. the key difference on the das is that they are female where the axles goes thus making both my axles male as opposed to the female ended axle that typically goes there

 

We broke one off in the diff last year. It was a lack of preload. We have pro series stuff now.

If you're breaking it often I would think that your preload is not preloading the driver side enough. I would get the DSS upgraded halfshalf and switch the left axle to a DC2 style. Good luck.

 

i have a DA halfshaft for 20bucks + shipping. PM me if you're interested, sorry to hear about your halfshafts snapping.

 

wait so DA intermediate shafts suck?..never heard this before. and im runnning one...

 

I didnt say they suck. they are just what i need and what i run. no big deal. Id probably be having this problem even if it was the regular ones.

 

^^ I don't thinks so Roy... Obviously no one else had this problem.

 

yea i know the difference, but you could call DSS, get a dc style halfshaft and a dc style axle and be done, you wouldnt have to change the passenger axle, just the complete driverside unit and seal becaus the "shank" on the da halfshaft is bigger than a DC one. or you could always sell ur axles and get the dc ones, im sure someone out there needs them. oh well, good luck, hope you find one that holds more than 3 passes.

 

ok we went testing and broke another one. i been asking around and it seems im the only soul on earth that launches at 8000rpms. so the new question is could 8000rpms, 10psi on the motor, and 6 psi in the tire be a big factor here whether its preloaded or not. a lot of people have said thats just too much load to hit it with from a dig.

 

correct me me if im wrong here, but the rpm and boost are irrelevant really because what really only matters is the power being put out at the hit, and hook at that point. for ***** lets just say its making 400lbft at the hit at 8000 and 10psi, how would that be any different than say a launch at 6500 and 5psi if it was still making 400lbft assuming all else is the same? in short, i would assume you arent making some absurd amount of power on the hit that others are not simply because of the rpm and psi. im not an expert in this though

 

Roy I dont think the problem is the burn outs or the launch or preloading or even how hard you are leaving. The problem is the da shaft, it does not like something in your set up. Change that **** out. It is the only real difference in drive line set up verse others that are at the same power level, weight and same chassis.

 

I'm sure that may be a possibility. BUT, I talked to jason hunt and he said he ran the exact same intermediate for 6 years and it never broke and yes it was a DA shaft. I'm just trying to get to the bottom of this.

 

Understandable, how much did his car weigh, what tires was he using ?

You have broke what 4 or 5 now, so the answer to your question is one of two things.

1 Something is wrong with your set up, bearing, mounts, spindles, diff., ECT.

OR

2 you have found the weak point of your set up with the da mid shaft and need to try something ( Different ) --- and by different I mean use what every one else is using (hint) NOT a da Mid shaft !!!

My money is on #2 because you have said you have combed over it thoroughly. So Fix your ****, I am tired of pushing your car off the line !!

 

Lmao fool you helped us one time. Don't act like you helped everytime it broke. And yes you are correct. It is 5. And its ****ing old already. Been old. He was running the 24.5 x 9 MT. The midshafts I believe are made of the same metal da or dc. So that may not isolate it. Don't know. Can't hurt to try I guess

 

put a set of stock axles in it and make some hits see of it still brakes the shaft or something els

 

Well what you really should do if want to go fast , scrap all that **** and go with an H !!!!

 

thats like being the fastest kid in the special Olympics

 

FWD is the special Olympics ,,, We are naturally at a disadvantage

 

get pro levels and be done with it.

 

Buy my car and be done with it

 

I saw someone break a shaft at IFO this past weekend and I'm pretty sure the problem was his diff because they put a new shaft in and it broke again along with the diff at the same time
