I cant afford a 12-bolt yet, so I'm working with my 10 for now. With my stall speed I have to upgrade the 2.73. I picked up some 4.10s and a carrier for a hundred bucks.
I'm planning on welding the tubes, and maybe adding some metal to the support cover.
I have about 500hp and the car slides and spins all over the place even with the 2.73s. With stock tires. I plan on getting some 275-315 tires soon. I need more traction but dont want to blow the rear. I wont be drag racing it until I get a new rear in, so no hard launches yet...

I dont want to spend the money on a lsd or spool for it, and dont plan on driving it too often.

Would welding the spider gears make the rear end stronger? Always dividing the power between the two wheels, instead of just one? Of course it would cause a lot of strain on hard turns, which I would try to avoid, or just goose it around.....

I havent put my blower on yet, fearing that I won't go any faster with these tires. And the fact that I have to drop my tank to remove the pump

 

Not a good idea.

The old "Lincoln Locker" has a habit of failing at the oddest times and creating ..... ummmmm ..... let's just say .... "sudden unpredictable handling characteristics".

Most tracks won't even let you on with that. Too dangerous for the officials, spectators, other racers, and anybody else within shrapnel distance. Let alone yourself.

 

No. No matter what you do, you still have a tiny ring and pinion which will always fail first.

Unless you're a professional welder, you'll never have them welded up good enough for straight line acceleration. Welded spider gears are good for dirt track racing or off road use in a 4x4 but not on a dragstrip. They're a big no-no for any street use.

If you're willing to spend the money to build a high HP engine then investing in the rest of the drivetrain to handle that HP is cheaper.

 

Soooo, just leave it open then? Man, I really need that 12...

 

buy a good posi

 

detroit locker + axles moser 31 spline

 

Yep, that'll be in the 12 bolt. I'm not putting more than 200 bucks into this 10.

 

mini-spool for $90 is cheaper and safer than trying to make a spool with a welder. It's not stronger, but it's the CHEAPEST posi you can get.
If you have rear discs that covers the "c-clip eliminator" aspect, so if you corkscrew and axle you'll know about it so you can pull over.

 

Putting a spool on a car the sees street use is an excellent way to break axles.

Same for welding the spider gears except that even more can (and usually will) break.
