Just a general question really, I was talking to my brother about possible engine swaps in the Victor when we got onto the topic of how the standard diff wouldn't cope with the extra power. He suggested welding it but not sure if that would help.
So are welded diffs only used for drifting? As when I do a google search on welded diffs all the topics are on drift forums I can't find much about it helping cope with more power etc.
Also has anyone ever driven with a welded diff and how different is it to normal?

mate of mine had one in a sierra was horrible day to day driving but made it drift at the flick of the wheel. personally if you are spending the money on upgrading the engine then brakes suspension and drivetrtain all go hand in head. Uprated diffs aren't that much money

To be honest I think you'd be better off looking for a better more suitable axle to swap in, depends what part of the Vauxhall diff fails, but I wouldn't recommend welding it on a road going car.

I would say it's usually the halfshafts that fail when you have too much power... Welding diffs is a cheap way to lock them, not really to upgrade the power capacity.
It also depends how much grip you have! So if you're worried about the back end, either fit skinny tyres or upgrade the axle, not just the diff

Cool, thanks guys, I didn't think welding the diff would be a good idea for more power. I'll probably look into this all a lot more closer to the time which could be a long way away.
There does seem to be mixed views on dailying a welded diff though. some saying its horrid and others saying they barely noticed it.

It's commonly the pins that snap when putting more torque into the mix. The welded dif is to stop the pin snapping. It gives extra strength to those gears but in turn stops then counter- rotating against each other if that makes sense

If it can be fixed with a hammer, then it must be an electrical fault

I briefly drove a car with a welded diff, didnt like it at all, any tight turn was accompanied with chirping tyres and you could just feel the half shafts winding up. Horrible.

Hi, a locked diff will make the car understeer and the inside rear wheel will 'slip' wearing out the tyres in short order, even with ordinary driving.

I've had a few dailys with welded diffs and it seems to really depend on the car as to wether it's a pleasant experience or not. My mk2 escort was horrible day to day, hopping and making terrible noises all the time. My 940 however behaves very well and is barely noticeable unless parking in tight spaces. I like the way it drives quickly with the welder and it's very predictable, more so than the locker it previously had. It's a little more effort to turn in to corners but doesn't suffer from initial understeer as you would expect. And sliding is easy and rewarding whenever you want to.

The difference between the Escort and the Volvo could be down to the differences in track/wheelbase.

I wouldn't weld the diff for the reasons you've given. I'd only do it if you were sick of the open diff or LSDs can't be obtained. If it was a drifter then it's a no brainer. Considerations are would your insurance cover it and they are a bit grey legality wise.
Personally I love welders and have driven thousands of miles with them, the main negative thing is chirping when parking. Once going they are barely noticable (my experience is limited to purely BMWs, though many BMWs) and in my experience do not cause noticable understeer. I also drift.
That said, if it's a road car that doesn't drift or drag race or anything like that then I wouldn't bother.

I have a welded diff in my e30 and all the above comments about it being a pain in the bum are true...but...its a toy that I drag out to abuse now and again, and for that the welded diff is a brilliant and cheap alternative to a proper LSD.But on a daily I would say it is only for the younger hardcore.not old farts like me!
