1992 mercedes 300ce
i have 2 mercedes 300ce cars i have converted to 5 speed manuals. on one i removed the fuel injection and ignition and refitted a 48mm idf weber and adapted a vacuum advanced 1975 ford grenada distributor with a gmc modual. the car runs AWESOME. porsche fast. i have a question regarding cam advance. i am setting up a microswitch to activate this. is this circuit normally open? and at what rpm does it activate. thanks! this is the dual cam m104 engine
i did find out the circuit is normally open, attached the microswitch and set it to activate at 2000 rpm. im thinking this is a safe estimate on rpm Last edited by william g; 10-29-2017 at 04:27 PM. |

I don't remember the exact numbers but it goes something like this.
Crank-off 1200rpm-on 4700rpm -off

Exact RPM ranges are in the FSM, however it's also based on engine load IIRC... won't be easy to make this work well.

thanks! the car runs great now. just curios if this will make a difference. i can fabricate a shaped cam to activate then deactivate at 4700 rpm.
the easy stuff is just that....easy |
