nick, a single turbo is already crammed enough underneath the hood of our car. Fitting a seperate collector pipe, turbo, wastegate, and downpipe is just down right ludicrous.

Only case, Noble M12...




And Duttweiler(sp?) IIRC




No the Duttweiler Focus w/ the Duratec was a single turbo.

You guys just don't get it; Twin turbo setups are only beneficial when the package permits a much better header design (the contour package doesn't by any stretch) and when an appropriately sized single turbo is not available.

People talk about the spool time, but that is mostly a moot point; spool time can be tailored with the turbine housing design. The big point that people mention is the moment of inertia of one larger turbo rotating assembly vs. that of a smaller one (for twins) but what people fail to remember, is that the smaller turbo for twins, is that only half the exhaust energy is going through each turbo.

As far as one making more power vs. the other; it is more dependant on factors such as header design and compressor efficiency than whether there is one or two turbos. Anyone that claims two turbos inherently makes more power independantly of the factors I mentioned, is an idiot.
