Well I posted pix here https://my350z.com/forum/event-photos/306627-pix-from-the-track-today.html

Anyway some friends rented the track and I was launching around 5k to 5,500 I made about 9 passes then on the tenth I broke my driver side axle. Anyone else had this problem? Or upgraded their axles?

 

A few people have. I know one of my local guys did with his Vortech Z.
He upgraded his axles, but I can't remember to what.

 

ouch

 

What tires? How much power? What were you running 60ft wise?

I broke the shaft on a stock one on the street. Ive also broken the inner CV joint on my 2nd pass with DSS Level 5 axles! I feel your pain...btw-how were you launching? Always PRELOAD the drivetrain!

 

I might not have been launching right? I have Mickey Thompson ET streets, I just have APS TTs exhaust test pipes and susp. it's at 9psi and spiking 11. I'm guessing I have 420-450ish hp. The best 60 I had right before it broke was a 1.7 I had 1.8s before that. I just started doing my burnouts in 2nd with the break fuse out, and I just pull up to the line hold it on 5,000 slip the clutch a tiny bit and it usually doesn't spin. How do I preload the drivetrain?

 

there's probably other companies that have them too, but I know AAM carries at least 2 different sets of axels:

Thanks for the find. I will be ordering those soon.

 

Sorry about the incident. That's a lot of power (and abuse) for the OEM rear end.

 

OP-hold the clutch just under engagement point and dont drop it.

Did you break an inner/outter joint or snap the shaft?

 

ouch, sorry to see that.

 

Not really sure yet, it's at the Nissan dealer right now, where it happen is an hour and half from where I live. The dealer isn't fixing it, just had to leave it there until I got a car hauler. I think that it broke the inner, it looks to still be in one piece. At first I thought it was the tranny, but it would still go into first and reverse, I backed up about 2 inches and it made a horrible noise.

 

Alberto, I just watched your videos you're an awesome driver mad props. It kind of sounds like you are feathering it right before you launch

 

Thanks, I have yet to launch the car to what I feel is even 90% of its potential. Id rather go home at the end of the track session. Still I pulled a 1.6 60ft...

 

So are you kind of feathering it? Whatever you are doing it is working great! a 1.6 is superb!! the best I had was a 1.7, what was the best you ran with your motor stock and just the turbos on?

 

Turbonetics was a mild 1.7 60ft, ran 11.98 and two 11.99's back to back at 114-116mph. That was under 400whp...

What I do is blip the gas usually from say 4000-4500rpm's watch the tree and when the light drops I go from blipping therottle to slowly applying it while letting out the clutch. It makes the transition very smooth for me, and has worked for my buddies as well. When I hold a set rpm @ the line I bog when launching. Aceman here in MD ran .1 faster 60ft's immediately after using this technique, he is now running 13.0 NA...

 

^ interesting bert...gonna try that next time I hit the strip.

 

That technique worked for me as well, cut 1.6's a few times, however I smoked the single plate clutch i was using after about 3-5 times doing it..
I can tell you from experience, this car does not like launch control to be used , and your method is best,and safest.

 

I will try it at least once. thanks for the help guys. keep in mind bristol where i go is the slowest track ever!!! lol i am planning on try some other tracks in the near future.

 

we have tons of 1.5s on stock axles. its all about that fine line of barely slipping the clutch and fully releasing it.


i am sure some axles are stronger for some different years, we both have 03s that are launching hard here...

good luck !!!

 

Since i have been using this technique and installed the 4.08 gears i have really improved my times at the strip.. I was running a best of 13.3 no matter what i tried. Now i am on the verge of hitting some 12's with a full interior car minus the passenger seat and spare.

Thanks again for the advise Bert.

I have snapped a axle aswell, but that was by not preloading the drivetrain. Keep the clutch right at the engagement point with out the car moving.
