Subject: Re: Reading Turbo Maps ? Good question: The short answer is "I don't think so". Having said that, someone will come up with _www.turbograph101.com_ (http://www.turbograph101.com) - - so don't take my word for it. I can tell you that there are so many variables, that every turbo graph/map will look very different (unless the AR, inlet housing, outlet housing, and turbines on both the exhaust and high pressure sides are identical). The profiles look like a Kidney bean profile to a black-eyed-pea profile. (upside down of course) It begins to make sense when you look at the pressure side and RPM side while at the same time considering engine size, compression, # of cylinders, efficiency of head/combustion chamber design, and realizing that this same graph/turbo you are looking at can produce a negative HP gain to a triple digit HP gain (different motors, # of ways to prevent detonation etc.) It MAY help to slam your finger in the door, while considering all the variables for divine insight, but I wouldn't chance it. Now watch somebody complain that there is no such web site as _www.turbograph101.com_ (http://www.turbograph101.com) . Ha-Ha-Ha. (LOL is so yesterday). SC Tom ===== ===== Bon Appitite' ! Brien.
