What you are basically looking for is the peak air flow you require the turbo to produce (although its a VERY rough estimate each 1 lb/min of compressor air flow can be translated to 10 WHP). Using a rough calculation (see prior note) if you want to make 450 RWHP you want to look at what efficiency the compressor is for 45 lb/min at the pressure ratio you plan to run. Not to talk **** at all but have you read the book Maximum Boost by Corkey Bell? It would help you better understand what to look for in a turbo (compressor and turbine that is).
Jet, the attached excel sheet might be of help to you. It will give you 6 points of CFM requirements
