| proportinal. Are they? You want all the exhuast heat your engine makes going into the turbine housing to make it the most efficent it can be (keeping the air moving fast). I think your explantion of the scale of the numbers changing along the Y axis based on temperature makes the most sense, but it has to be dependent on the intake charge temps (@ the compressor outlet when looking at that chart, AND after the IC's when looking at the entire system as a whole, not at that chart) directly (NOT directly upon the EGT temps). Regardless of which temps we base this number on, it becomes obvious to correctly read these maps we need to have different sets of numbers along the Y axis for different pressures at different temperatures. To be able to accuratly extract meaningful information from these charts we need to come up with a temperature/pressure conversion that makes sense for them. for example (not anything at all accurate) 21psi @ 500 degrees= 27 psi @ 800, to properly see where we are on those charts. Is any of this making sence or am I hopelessly lost? The more you learn the less you KNOW. And since it is obvious the flow helps sebs car make more power at less PSI (via lower intake charge temps) what exactly is causing the intake charge temps to be lower? Or am I incorrect above and it IS the lower EGTs that make intake charge so much cooler(denser)? Thank you very much for your input Tektrader69, you are helping me make sence of all this, albeit slowly.
