We have all seen dyno sheets but this one from the 588 HEMI is interesting for a few reasons:
1) There are two plots, one with an air cleaner and one without. Note no change.
2) If you are getting close to max HP the HP curve stops climbing and goes horizontal as torque drops. This pull stopped at 7000 RPM but as you can see "it wants RPM!" and the torque curve is very flat.
3) A BSFC of .43 shows that the engine was very efficient and happy :^)
