03/04 Cobra guys are right for the 03/04 Cobra's. If you run the Cobra's without the SC belt the power steering and water pump are on that belt.

 

I see

 

No, the Lightning’s do not have an active knock sensor. There is a sensor on the motor but it is not activated. The reason is it will not function correctly due to the vibration from the supercharger. A knock sensor is a stupid device in that it merely senses a vibration and if the vibration is within its limits it will cause the knock sensor to produce a voltage that is feed to the ECU.

The ECU uses this voltage signal to determine how much it should retard the timing and on what cylinder it should retard.

Due to the vibrations produced by the supercharger (it does not matter if your making boost or not) the supercharger does cause vibrations due to the rotating mass of the cylinders inside the supercharger it is most likely to close to the same vibrations or frequency range the knock sensor is sensing for.

Since Ford was not able to develop an adequate system to deal with pre-detonation (knock) there is no such unit currently active on the Lightning’s and thus the reason for a higher octane fuel.
