Next up is Cam phasing. Until now the cam has always been installed "straight up". Now we are going to advance and retard the cam 4 degrees to see the effect.
Advancing the cam shifts the VE curve down in the RPM range, while retarding shifts it up. The shift is relatively small, but not negligible.
If you are considering shifting the cam further than 4 degrees because you want to move the VE curve further, you need to pick another cam. |
