Vehicle Movement (RPM)

Not sure if something has changed but I found this:

Dynamically adjust vehicle engine rpm in a blueprint

Hi I would like to be able to adjust the RPM of a wheeled vehicle. I can do this in the side window (under details) but I want to be able to adjust during game play. I’ve searched for get/set rpm in the blueprint window but it doesn’t seem to exist. Is there a special way to locate RPM variable in blueprint scripting ?
