RPM change on a 3.2 when oil cap is removed?
The recent topic of RPM drop on an SC when the oil cap is removed made me curious - approximately how many RPM does your 3.2 drop when you remove the oil cap? Like when you check your oil level?

I never heard it quantified and the DME on a Carrera should adjust for it so it will be momentary. The point is that if you can't discern a change then you probably have a vacuum leak.

Same question but for a 930. Should a 930 have rpm drop when you open the oil cap? My old SC used to drop, but my 930 doesn't at all?

On the 930 the oil system isnt sealed, the breather hose from the tank goes into the back of the aircleaner where the SC and Carrera oil line taps into the injection system after the airflow is measured. False unmeasured air gets into the mixture causing the idle change.
