Thanks Bob I did all these calcs about a month ago on the spreadsheet . I used this site to check my answers, I was dead on with the compressor mapping section . I will be running 15-17 psig max and I believe the t04b-46mm trim to be a nice unit. Do you have anything else to add about turbo selection .
