I've got to collect my new Delorean tomorrow and the speedo is not working!!! (I've scheduled a day of diagnosis)

On the drive from the old owner to my garage, I'm conscious of not going too fast, so my question is.....

In 5th gear (manual box) what RPM show at 50, 60 and 70mph?

Many thanks.

Steve

Print this out in actual DPI (dots per inch), not adjusted to fit page, and scotch tape it to the instrument cluster lens, directly over the speedo face:

45057

Illumination will show through so you can still use it at night.

xRef is designed to be readable at a glance. 2.4 in italics is 2,400 RPM in 2nd gear for 25 MPH. Everything is else RPM's/speeds you are likely to encounter (no need for 35 MPH in 4th gear for example).
