Two 1,000 cfm turbos should still be able to flow 2,000 cfm if the engine can reach high enough boost levels and/or RPM to swallow that much air.

I seem to recall that the mutiple turbo (per cylinder bank) setup's are attempts to reduce the lag caused by a large turbine (on large turbos) while spinning up. So while you _might_ make less power, you stand a much better chance of getting your power earlier and thus broadening your powerband. As far as I am aware, there's no reason why a single turbo should make more power than multiple turbos. Surely it's just a matter of flow and pressure development. If you have two turbos in parallel developing 20psi each flowing 1000cfm then that should be the same as one turbo at 20psi flowing 2000cfm(?). I'm ignoring a number of things (such as plumbing and dynamic effects) but I think that's pretty much the crux of it.

For V12 or even V16 engines, I guess the 4 turbo setup is probably advantageous cos it simplifies your exhaust manifold design....

I think it can only be a good thing jmartinez1170. You can use the time to learn to use punctuations. [monotone voice]You seem to type like Kimi Raikkonen talks yes. Is it intentional i don't know... [/monotone voice]
