I thought the more turbos the better. Look at the Bugatti Veyron, no, not the one in the water from the cell-phone distracted driver. The ones on the road.
Or in my line of work with Volvos, the 2003-2005XC-90 has an inline 6 cylinder with 2.9l of displacement and 2 turbos with a power output of 286 hp. Seriously de-tuned to comply with Volvo's hardon, errrr.. I mean, commitment to safety. They feel slower is safer.
I believe smaller turbo's spool up faster and running two smaller turbo's make sure you don't lose top end. I think some multiple turbo's can be set up so that a smaller one comes on line first witha second one coming online latter. I think i will be fine with a single and am leaning towards a ball bearing turbo for quick spool up.
