there is a discussion in the vw race forum www.improvedtouring.com about the pros and cons of diff welding vs a quaife.

Re: welding the dif? (rockit)
There's avery good "how-to" for welding your diff at http://www.specialstage.com It's in the *technical* links off of the homepage.
One comment I remember hearing about the welded diff is that you *have* to be on the accelerator to turn the wheel.

in racing should you be for the most part?

Yep. Except for those pesky long, decreasing-radius turns.

rockit, i wasnt able to locate that discussion between the pros and cons. how far back was the topic?

Re: welding the dif? (dub monkey)
sorry. i think the one i was referring to is actually in the tech talk section under "who in the NE can weld a diff" and it isnt actually vw specific, although there is some comments by people running welded diffs in their dub racers.

you CAN turn with a welded diff, just you should be ON throttle to turn.
they work GREAT in the loose stuff http://****************.com/smile/emthup.gif

With a locked diff, it will not spin the inside tyre no matter what the cirumstance, which rules. the torque is also a static 50/50 split, also a bonus. because of this the tyre with the most weight on it due to weight transfer has the most "pull" if you will. with the outside tyre weighted more the locked diff actually HELPS the car turn better beleive it or not. it helps rotate it through the corner. *only applies when you are ON the gas*
if you're off the gas..kiss turning goodbye

you should be done braking BEFORE starting the turn in. this is not only the fastest/proper way but the ONLY way to get yourself through a corner quickly and properly with a welded diff. with a LSD you can be off the gas and still turning, same with an open, so it doesn't emphasise the proper techinique as much as a welded diff does. besides, a welded diff if done the RIGHT way is super super strong. http://****************.com/smile/emthup.gif

that's all outta me for now.

Re: welding the dif? (opusdestructo)
I recomend welding diffs for rallying(gravel, mud, snow) or oval racing (mud)...thats it! in road racing you need to be able to improvise, be creative and push the limit a welded diff makes it difficult even for the best phisically inclined driver ( under 5'7' 160 of muscle, short arm, big arm) it is very difficult to show the many different subtleties of road racing to a driver that uses a welded diff, because he can't control the machine, the machine controls him.... and when they break (and they will in road racing applications) they bring everything with them,,,, gears, casing etc....

). You will not lock the inside tire when trail braking either. An extra bonus is that the initial cost is a lot lower. Now I think the best setup would be an adjustable diff that you can tweak accel and deccel lock rates seperately, but for my purposes welding works great.
I know that Chuck Mathis ran one in his ITA Golf when he won @ ARRC and Chris Albin has been running one in his ITB Golf for a long time. Chuck ran the same transmission for 6-8 years with no problems. Chris is a little harder on his eauipment. I have also noticed that a number of other IT guys are making a switch from ltd slip to welded.
However I doubt this would work well in a high hp front drive car, and know that it would really suck on the street.

They certainly require a higher level of driveline maintenace, and you do need to stay away from the pretty little 'racing' steering wheels for leverage, but on lower hp cars (like IT) the welded diff works well. You will always be able to put power down, even when banging the apexes. The quaife will spin the inside tire happily when you lift it off the ground. You will be able to run a more agressive front sway bar, because again you can be on 2 wheels and put power down (sorry to blaspheme to all you shine fans

Re: welding the dif? (chois)
From what I understand, the only time a welded diff gets real dicey is when you've got a track that's drying out but still has some spots of standing water.
I was really dissapointed w/ the amount of wheelspin I was still getting w/ a Quaife. Had I known that's the way it was going to behave, I wouldn't have spent the money on it. Next race tranny I build will have a welded diff.
What we really need is something akin to a Detroit Locker. This acts like a spool when you're on the gas and an open diff when you're off it.

Re: welding the dif? (16v)
Off-road people weld the diff's in their trucks some times. mostly its reffered to as a "poor man's locker" or "lincoln locker"
didnt some older Audi dasher or something have a lever on the dash that would lock the rear diff and centre diff?
