Sorry Don, I lost the point - which set up are you referring to with this " half speed from now " ?Idling at 700 RPM shouldn't be too fast around a parking lot, half as fast as your going now, and no jumping. Download the spreadsheet in this thread and enter your tire size, rear end ratio, transmission ratio, and RPMs and you'll get your speed (in mph).
