What is the differance?? Discuss.
Please correct me if im wrong, but the way i understand it is (short and sweet)
Twin Turbo - Both turbos are Pressurized by the entire exhuast system (IE Inline 6 all 6 exhaust ports are used to pressurize both turbos)
Bi Turbo - Each turbo is pressurized by its own set of exhuast banks ( IE: Vee Engine, one sides runs one turbo, the other side runs the other, they all meet at the TB.)

Interested as well... But I agree with Deepseadiver, I think it's the other way around. Bi, meaning both, and twin meaning the same but separate (u know what I mean). So a twin turbo sounds like it would have it's own exhaust source, bi turbo sounds like it would share the same exhaust source. If anyone knows for sure, chime in.

The difference between twin turbo setups are if they are Sequential or Parallel
Seq is when you divert most of the flow to the 1st smaller turbo and prespool the 2nd. Then kick over and use both. (Like the FD RX-7)
Parallel is when you have a setup like the 300ZX.. Where both turbos are on all the time trying to spool up.

They both mean the same, Bi-Turbo is Audi's common name for their twin turbo setup.

twin turbo - i take it as 2 of the same turbos powerd by 1/2 the engine ( ex v6, 3 cylinders per turbo )Originally Posted by nhsean69

bi turbo - 2 turbos but different sizes, meaning using the small one to have spool the larger one faster...

That's how I always understood it. Bi-turbo two different sized turbos. smaller one for low rpms, bigger one for upper rpms. Twin turbos are pretty much equal size and used for the entire powerband.Originally Posted by TeamAccolade

True but in the Bi turbo setup both turbos can be the same size as well for example Volvo S80 T6- 2.9l Staright six Bi turboOriginally Posted by Monkey

i dont think that this is correct, a later model s4 (2002) runs a bi-turbo setup, in this setup there are two turbos one on each side of the v6 motor both the same size (k03's) and each spool at the same rpm and make the same boost unless one is damaged of course.Originally Posted by Monkey

it would either hold full boost or "turn off"
