What rpm do cdis turn at 70?
 

Any cdi owners out there?

No cdi for me
 

I don't have a cdi, but my brother told me that most cars run at 1/2 rpm's of what the speed is. I never paid attention to that before, and don't know if it's true, but when we were doing 70, damn if the car wasn't at 3500 rpm.

Sorry I can't be of more help.

While its not 70 mph, that is the read ratio.
