I have the opportunity to pick up a 60-1 for next to nothing. It has an A/R of .63. From what i've seen using the compressor maps on here Turbo fast and the flow values from turboflow . It looks as if it would be fairly efficient for medium boost (10 to 20 lbs at 6k). Anyone one know what kind of spool characteristics this would give or if it would be a good match?
