This includes track time & street.

At the Motown Muscle event a few weeks ago, I discovered from 3 different people, that my posi was blown. I'm doing 1 wheel peels. So I'm not sure what I'm loosing in ET, but my 60's have gone from a best of 1.50, and an average of 1.52, down to 1.60. So I'm obviously loosing something in ET, and perhaps in overall MPH.

I still won King Of the Hill, with a best of 10.9@125, (1.60). Average runs were 11.0.

The car runs fine on the street, so I still can drive it, but it's wounded.

The good news is that the dealer is going to overlook a few things, and replace the posi unit. "This is a onetime deal" Ok, I'll take it.

So I will be able to go to the track & get some runs in to see what, if any I lost with the posi being blown, before I switch to a 12 bolt.

I cant complain about the stock 10 bolt. It's been good to me.

Well I have about 240 to date with 21K miles. But that's starting out stock and building to where I am now ... I'm not hitting quite as hard as you.

So far the rear end is still going strong and displaying no symptoms <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />

Some folks just seem to have good luck with the stock rear, while others can break them just by driving down the street...

I don't know how many runs I had on my 10-bolt when it was replaced with the Moser 9", but it was probably only a run or two from coming totally unglued. There were 3 or 4 pinion teeth floating around that had broken off...

I have had to replace the POSI once - with a Eaton. But otherwise well over 300 passes and 18K on the street.

300+ and still going. Half of them in the 1.4 - 1.5 range. I do notice every now and again on video that one side spins more than the other during my burnout and rollout.

I think BradWS6 has the most passes on a 10-bolt that I've heard of. I don't want to throw out a # since it was quite a while back, but I do remember it was something crazy.

My 10-bolt is doing just fine so far (knock on wood). I have right around 50 passes on mine, the slowest 60' was a 1.77. My quickest is a 1.58, and I'm averaging 1.60's right now. I'm hoping that it will last me for quite a while. With as much as I beat on it, I may go in with a new posi at the end of this racing season.

No BS here, I had around 800 (I quit counting at 600) passes on my stock 3.42s with an M6 on nittos. My 60s suck, 1.95- 2.05 leaving around 3000 with a 3650 raceweight. When I had 3.73s installed recently, the installer said all lookrd good including the posi. He asked me If I wanted the old 3.42s. I didnt, he said he would set them up for someone used!! Thats no BS. In my 97SS I broke some teeth off the pinion at 34k with around 150 passes.BTW I had 46k on the last set!

You guys cutting a 1.5-1.6 60 on the stock 10 bolt, what are you doing? Dumping it? What tire are you using? My best trap was 115, best time was 12.2 with a 1.8 - i'd love to cut a 1.5-6 and pray that my rear doesn't snap in two, so whats the deal!!??

I had probably 40 6k dumps on ET Streets w/ my stock 10 bolt and clutch. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
I went with a 12 bolt and a cartek clutch before anything went out on me though.

but ive got around 150 or more counting all of my passes when i only ran 13's do to 11's

probably 50 1.58 60's up to 1.64's

also i get the one wheel burnout once in a blue moon, but it seems to only happen if i dont back into the water box. One still smokes a little more than the other, but i see alot of cars doing that. Heck some only burn one wheel and still cut 1.5's-1.6's <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

the A4 rear is alot stronger than we think.. if mine ever goes i might just put a 10bolt back since it doesnt eat up so much power and add weight <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

So you dump it at 1,200rpm?

your best bet is to get some sticky tires and dump it from 6k, but you drivetrain may not like that.

I got ~50runs w/ 3.42s and another 125+ runs w/ 4:10s on my stock rear. I did blow the posi up once, but that was it. 12-bolt is in now and it makes 6k clutch dumps on 28" slicks alot of fun <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I'm runnin high 11s-low 12s still on stock 10-bolt with 2:73s. I've got 65k miles on the car now. I race just about every weekend. Street race during the week. Haven't had any problems <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> **knocks on wood**

Well I broke the the posi in the stocker 3 times! I guess i just SUCK <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I had free replacement every time becuse of my buddy at the dealer. But i was Still getting sick of it. Then the 4.10 pinion gear spit out a FIEW teeth so i said. "i'm done with this POS" 12 Bolt holds up alot better. IMO its like a chain reaction once you break it it was flexed too hard. From there on out its worthless. Well atleast in my case. But i just have all the luck... For what its worth i also never did a TA cover and WAS on 100% Stock suspention. So maby i justt neede a little more stablization. Heck i dont know it just felt like a tooth pic...

I've broken 5 rears (be it gears or posi) in about 150 passes with nothing more aggressive than nittos. Finally I replaced the damn thing with a 12 bolt.

Update on the stock rear end: The car sits at the dealer, waiting for the right series carrier to get there. It is being replaced under waranty <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

There was very little metal powder in there. Everything looked good, except for the posi, which was toast. I will be getting it back tomorrow, & planing some runs in about a week. Hopefully my 1.50 60's will come back. I'll know soon enough if it was the rear end causing the reduction.

I'm still shopping for a 12 bolt, but holding out for the absolute best price.

I'd be happy with another 50 passes on the stock rear. I will be running the Royal Purple 85-140 in there again. I think that provides a good cushion between the gears.

Hey man shoot me a mail about the 12 bolt. I got a decent price on mine. I can give you details.
