Let me correct myself first, the disco potato turbo is a garrett GT2860RS, but the map of a 60-1 looks a lot like the garrett and goes to a higher HP level.
The books I like are:
Maximum Boost by Corky Bell, Robert Bentley Publisher
Turbochargers by Hugh Macinnes, HP Books
Turbo Real World High Performance Turbocharger Systems by Jay K. Miller, SA Design.
