The only compressor maps I found was on turbonetics.com.... I found the turbo that was 2.11 pressure ratio, 30 lbs/min and 73% effiency. On turbonetics.com, if I read the compressor map properly, it would be the TO4B V1/V2. Notice me if I'm wrong......I'd like to know which company you guys think is the best if you have any idea about it. I have planty of questions. I'll probably start another topic for this but before, I'll try to make my decision on a turbo on this topic. Thx a lot eckoman_pdx and Thepeug
