  The following is a mathematical model of the fuel injected 6 cylinder engine used in this project. The numbers are based on all the mechanical dimensions of components, intake dimensions, throttle bodies, injector sizes, measured compression, etc etc etc. The analysis was done with Engine Analyzer Pro v3.  The second chart is the plot of hp vs torque.

    The interesting things to note....

  1. The PkTq and PkHp numbers (in the upper right corner)
  2. The two 'peaks' in the Exh Temp Deg F exhaust temps at 4500 and 5500 rpm - they seem to follow two power spikes VERY noticeable while driving. They're assumed to be the tuned resonance of the intake design. (haven't held it at 6500 to feel that one!)
  3. Vol Eff% (VE) numbers even seem to match the Megasquirt (controller) VE tables!
  4. The In Port Tmp F at least at 2krpm appear spot on, as measured with a thermal laser temp. probe 

   I can't wait for a full dyno run!
