Can a stock SVT Diff be welded tight???

Been playing around with this idea for a while now. I had it done on my other track car. Since I have a spare tranny, I'm thinking about doing it.

If this is performed, the car will only be driven at the drag strip, since I won't be able to turn the car without screeching one of the tires.

Has anyone done it before?

Are you....serious? You're going to turn an SVT into a dedicated drag car?

I'm sure it CAN be done. The problem is when/if it snaps, but its up to you. I have heard of a few Rally guys that do this on their budget build rally cars.

Sure it can be done but you dont know how long it'll hold, it could break the first time out or it could last years.

I'm not going to condem doing this, one of my old drag mustangs was welded up and it took a beating and the last time I heard from the guy it was still holding up fine... its been welded up for a few years now.

Now keep in mid if you're planning to do this to an FI car that the stock diff is the weak link in the system and they will break.

I was thinking of that. But if it's in a dedicated rally car, a broke diff would just sit you out for the rest of the race till you get home to install a new diff or replacement tranny.

a diff properly welded will be fine...you have to strip it right down and weld the spiders so they can no longer turn..fill the teeth right up with weld. if you try just welding the spiders together thats when they will break, i ran a welded diff in my old carlton gsi that i used for drifting back when i lived in ireland..3yrs of beating on it and it never broke you just have to make sure its done correctly.



this is the way most do it and this is wrong...eventually the weld will break.

My dads old rally alfa had a welded diff for one race. The welds broke and it worked as an open diff. I couldn't believe he didn't grenade his trans. Lasted a couple more rallies after that till he rolled it. I guess just make sure you welded it thoroughly.

just a thought, your wheels spin at slightly different speeds when turning. I can see welding the spiders on a front wheel drive street car being an issue when you want to turn. Will probably have understeer and a lot of tire noise/wear.

He said it will be for drag only, not for the street.
