Speedo Overreads
Posted: Tue Jul 14, 15 8:45 am
I realised this weekend that the speedo in my car Overreads.
That's a first, I've had a few that read massively under, but not this time.
At an indicated 60 I am doing 65 according to say nav, and at an indicated 30, 32-33 according to say nav.
So it seems to consistently over read by about 10%
It's not a really big deal, but obviously it would be nice if it was accurate or a little under.
I do have 15" wheels when I presume 66 Belvedere II would have come with 14" wheel, so that's probably the difference?
The car has also had a 440 and 727 transplanted, with 8 3/4 rear end, different gearing again...
Again, not that worried, but is there anything I can do?
