    here's another turbo calculator over on motorgeek that I've used a few times (originally by Eric Fahlgren). We added the ability to plot against various known compressor maps given some data points. Useful for figuring out what turbo is right for your power goals.

      Ohh - quite nice - the way values can be plotted on a selection of maps - neat !

      Sadly my computing skills don't extend that far... I'll have a play with the calculator for comparison purps - I see it caters for funky fuel and WI systems. I haven't bothered with that stuff yet !

          I am trying to model stock RS2 in the sheet to better understand engine specs.


          Can you guide me if the VE values are right or wrong?
