Thats ALOT of air coming in...

Not really they are small turbos. He'd make better power with jus a TRU Bi-Turbo setup, but im sure he did this for the WOW factor. that Dyno run wasnt impressive at all. Ive seen 400hp dodge neon running a single turbo with 21lbs of boost on a 2.4L motor. You never heard the exhaust, all you heard was the AIR being sucked into it. It was awesome. lol
(Bi turbo - two turbos that arent connect to each other) (Twin Turbo - one feeds the other.)
Maserati had a tru BI TURBO setup. Dont think anyone else did.

It is all a matter of terminology. I have heard of aviation guys calling one turbo feeding another a staged setup. No offense intended, but I have only heard the term "twin turbo" described your way when someone did not know what they are talking about. You also left out sequetial turbos like those found on the supra twin turbo.
I will try to do some research and report back.
ETA: from the banks website:
What kind of problems are likely when using two, staged turbochargers?
It is common to use different sized turbos when the turbochargers are "staged": that is, the compressor discharge from one turbo feeds the compressor inlet of the second, and the compressor discharge of the second feeds the engine. The most likely problem is extreme heating of the compressed intake air. A charge air cooler (intercooler) should definitely be used to cool the air coming out of the second turbo.
Also from the banks site, a picture of one of thier "twin turbo" motors. A chevy V8 if I am not mistaken.
Here is a bit from the ray hall website that talks a little about converting a sequential system into a traditional twin turbo setup.
www.turbofast.com.au/lexusturbo.htmlOf course there will be some overlap in terms depending on design, and how they are implemented, but the three basic terms that I have outlined here are used in all of the turbo circles that I am in. Also, I would like to point out that bi-turbo is a viable term, but it is usually reserved for fancy pants foreign cars like the aforementioned maseratti. YMMV.
