What's the difference...

I know this doesn't directly apply to Foci, but... Technically, what's the difference between a single turbo and a twin turbo setup? And don't say, "there's two..." I realize that. I understand how a turbo works and why it works but have only ever really played with a single setup. In truth, I've never seen a twin in person. So what's the difference? Are there advantages/disadvantages? Also, it seems that people that have a twin turbo factory setup (lookin' at you Supra people), like to convert to a single turbo... I'm assuming when designing the stock engine, they used twins for a reason, so what's the purpose of converting to a single? I know it's probably a big answer that depends on alot of other variables, but any info would be appreciated. And no I'm not thinking of putting twins under my hood...

I'm not a turbo guru, they can chime in, but from my experience, twin turbos people will sometimes run two different turbos, a small one that will boost at lower RPMs and a larger one that will carry the boost through the high rpms, I think... Don't quote me on that though.

Another thought I just had is on V6 or V8 cars you have headers on both sides so it would even everything out having a turbo on each side but 4 cylinder cars I'm not sure maybe a turbo to push a turbo? That would be sick, ok someone that knows what they are talking about can jump in now... HA HA

That makes sense, but all those stock twin supra owners like to convert to single...

As far as I know, you can run twins either sequentially (low-end/high-end) or separate, one off each header.

Then there's the Bugatti Veyron with quad-turbos. :)
