i would think 2500-3500 would be ok if your not dumping the clutch. thats what I do with my car 2500-3500 on street tires

Well, like I said there as well, the stock from an M6 really takes its toll on stock 10bolts Not sure what a fairly safe launch is with DRs though. Autos are different, and can laugh quite hard on them. Merv finally wrecked his with his LS motor swap (I'd say at least 480hp)

So what you are saying is its not safe to drop the clutch from like 3000k?

iTrader: (3)

Right. Especially with stickies. Street tires will spin (usually) before it brakes the rear.

Damn that sucks...so do you think I would do better on street tires? I hate to break this now... not til I have money for a 12 bolt or a 9"....my 8.8 in my fox with 3.73's moser axles and c-clip eliminators would hold 6500 drops all day on slicks...damn this shitty chevrolet rear end....

These 10bolts are 7.5" which as you can tell is 1.3" smaller than your Ford. 8.875 is the 12bolt, and there is a GM 10bolt 8.5 that was used in the 80s bigger cars like the Grand National (and I assume like bodied cars like the Monte) and I think the El Camino got that too. That doesn't direct bolt in though, would have to be modified. On Moser's site, the 9" is $985 for the F-Body w/ Torque Arm ($885 w/o) and $1250 for the 12bolt

Ok so launching on dr's like my grandma drives her taurus what times am I looking at? Is it even worth going to the track?

Sure it's worth it I'd just probably launch @ 2K to be safe. Maybe not warm up the tires first and see how much spin you get.

I have an aftermarket Unit.. an Auburn Pro Series Differential rated for 500hp/tq.

Personally I think it may have sheared an Axle.. I haven't got into it yet, I plan on doing that tomorrow when I get off of work. Carnage pics to come..

I was consistantly cutting 1.56-1.58 60ft's, bringing it up to about 1300rpm's on the line and drilling it as fast as I could to the floor when the light went Green. I was on MT ET STREET DRAG RADIALS, 275/50R15's on 15X8 Draglites.

M6 cars aren't as forgiving as Auto's. As far as a Stock Unit, I killed mine with my Bolt-on LT1 pulling out of the Driveway. I just put on my Brand new Z06 Wheels with 275/40ZR17 BF Goodrich's and was about to go on a cruise..I was pissed..

Ok well I went last night to Kennedale and I launched at between 2000 and 2500rpm....9 flat consistenately. Wouldn't spin...but It was really consistent. This car definately is not a 1/8th mile car, it started pulling hard about half track. I think it would do good in the quarter. 9.009 at 87mph . It was just slow out of the hole and I was an hour and a half from home and didn't wouldn't to break it.

Im on my 2nd ten bolt now. The first gave out while simply taking off from a stoplight very conservatively. I am now saving for a 9" so that I can drive my car without being scared every time I give it half throttle.

BattleShip

What was your 60 foot time? 9.009 is DAMN good for a CAI, 4.11 and a stick. That mph seems wrong, I was running 7.8X with 88 mph have a feeling yours should be ~78 mph.

Regardless 9.00 is really good considering that most stock LS Camaro's ~9.2 in 1/8

For launching hard, a friend was running 8.7 and tore out 2 sets of axles. He dumped I think ~3500. I won't say they are weak, but they won't take alot of abuse and with sticky tires it is abuse on launch.

Slowmaro95Z28

What is the difference between a m6 dumping the clutch at 3500 or me running a 3500 stall in my auto? Wouldn't it be the same deal?

BattleShip

No the load is different for an auto and a stick for foot brake setup.

Sitting at the line with an auto your drive train has a larger load on it than he does when his clutch is almost totally disengaged. Then at launch he goes from nearly no load to...

Your load increases, but not as large as of a change as from a stick.

Slowmaro95Z28

Thanks. I never heard it explained that way. For the mods in my sig on MT ET street radials does anyone think my rear might give me any problems? It's out of an 00 Z28. I added the 3.73's. I haven't run the car or even really driven it since the cam swap so I have no clue what I'm in for. lol

Yeah, as stated, an M6 tears up a 10-bolt pretty quickly when launched aggressively. Mine lasted to the 346rwhp mark before it gave up the ghost for good. It was the track and sticky tires that killed it.

for just the housing.

you need to probably just take off from an idle, you know just kinda gas it as much as you need for how much the engine is bogging. no need to rev and dump on the tee-bizzle.

Yea I still think I could have got into the 8's....I only made like 6-7 passes...and dead on 9 every pass. Launching really easy...not to break it. And yea stock....full weight spare jack 1/2 tank gas on regular unleaded. No cats, slp lm1 dumped over rear axle. 4.10 or 4.11s whatever they make for this rear end...and I just realized it is not an slp CAI....it is a cheap O'reilly cone filter on the end of a POS chrome pipe. No other performance mods. Stock plugs and wires as well. Oh and a new stock clutch from Vatozone. I am not really shooting for a 1/8th mile car...I am going to be doing a cam and headers here pretty quick...stuck between mid-lengths and lts because I want some more low end power...and for around town this rear-end ought to hold up for a while...eventually I'll do something to the rear....
