I don't have one, but in general terms here's how it goes......A big single turbo can give you every bit the power of twins, but packaging issues can be a hassle with a single turbo. Additionally a twin set up is usually much more driveable on the street, given that smaller turbos will tend to spool up quicker and provide boost down low (think throttle response). In the drag racing world where you are launching at rpm under load the single works great. Now these are of course generalities but they hold true for the most part, remember it really all depends on how much power your trying to make and how much room you have for all the given parts. Hope this helps.
