I'll be honest, I was pretty sure it was always spinning, but not positive. Why not ask? Some faceless screenname on CumminsForum is not going to offend me so don't worry.been awhile since I've been on here and over the last 4 posts I've read I had a smart az comment to make for each, but have restrained myself.....come on, don't make it so easy.
Think about it, exhaust is more or less airflow, and must pass your turbo. As your cranking it over to start the turbo is starting to move, ever so slightly but still trying.
Like they say though, a stupid question is one that is not asked....until now! :hehe::hehe::hehe:
just being a smart az, don't take it seriously, just could not resist takin that poke anymore
