just wondering how many of you LT1 guys are spraying with the 10-bolt and are having it hold up?

Im planning on spraying a NX 100 shot here as soon as i get my kit hooked up, and i have 3:23 gears. On the street i run nitto 555's and looking to switch to the drag radial, and at the track i run 16 in. ET streets.

im also going to put a T/A girdle on it.

 

i cut 1.5X's on my stock 10 bolt, no girdle. Spray off the line too.

 

well, they aren't lt1 cars, but both still have 10 bolt in them. i did put 3.73 gears in them. they did have 3.23 gears from the factory. run nitto DRs on both cars. wil lbe using the ET Streets this saturday. going to break a ten. 10 second ET or ten bolt. either will do.

 

Ditto. Except I do have the girdle.

 

A4's are much easier on the rear than M6's; it's the shock that breaks the rears. You could always hit the spray after the launch if you're really worried.

 

I spray a 150 shot off the line. Everything was good until I started cutting 1.5X's 60 ft's. Then I cracked the carrier, and smoked and axleshaft. It's not if, but when with an M6

 

What kind of 10-bolts ARE they?

If they aren't the newer F-Body 7.625" rears, then they are either 8.2 or 8.5 corporates.

The 8.5" corporate is as strong as the old 12-bolt, if not stronger.

 

Check his sig.

Agree about the "when not if".

Sprayed 150 off the line w/ stock 10-bolt stock w/3.42 gear (99 LS1 Zexel). Ran a 11.34@119 cutting 1.66. Ran the stock rear with both et streets and et street radials. Now I got a 12-bolt strange w/3.73 .

 

10 bolt out of a ls1 6speed, 3.42's from an ls1 6speed, with the slp posi. All put in my 94 z auto cuz I destroyed my 3.73's messing around on the street. Best its gone is 1.53 on a 150 shot. Its gone numerous 1.57's. Nitrous comes on at 2600rpms have a 2800 stall. This is all on mt et dr's. No girdle.

 

Cut a 1.7 on the spary, it held for a while.

 

I have sprayed a 150 shot on my stock ten bolt (with gridle) for 3 years nows, and the diff is just now starting to go.

 

What are the signs of the diff going?

I've never sprayed my car yet, but will be doing so this spring through a m6 and stock 3.42 gears on et street dr's. Added a LPW girdle and pray that it lasts a little while

 

mine sounded like a train



good luck on that, i broke 2 sets of gear only pulling 1.8x and with only 380 rwhp

 

I did a few times...then it blew up.
