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.

Anyway, just coming back on topic, does anyone know if Owen dev. have put it on to an actual car, or is it still a project engine. - i can't seem to get to their site right now...

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]

this looks great but it will be impractical! its more of an example of the enginering work that owen is capable of! it has been widley pubisized over here inthe uk that this is a one off!
and can you imagine the cost of this kit?????? it would be exspensive!
