Re: [DML] "1980's Delorean Speedo Cable Fix"

["Martin Gutkowski" <martin@xxxxxxxxxxxxxx>]

The drive ratio on the original angle drive is 8 turns of the wheel to 9 turns of the cable. If the drive had a 1:1 ratio, it might explain what you describe (though equally delorean speedos aren't renowned for their accuracy!). Easy enough to check.

Best Wishes,

Martin

I've been really happy with my SpecialTAuto angle drive since the day I got
it.  I've had my SpecialTAuto angle drive since John first started selling
them and I believe I've logged over 15,000 miles on it.  The only thing I
noticed wrong when I installed it was that my speedometer was a little bit
off.  What I mean by this is my speedometer shows a speed that is about 11
percent slower than I am actually going.

I verified this by comparing the speed on my speedometer to a GPS and to
the RPM speed chart.  Basically when the car says I am doing 65mph I am
really doing about 73 mph.

Since day one I thought nothing about it and figured it was a problem with
my speedometer cluster being out of calibration.  I bought a used
speedometer cluster on ebay a couple of years ago and I finally got around
to hooking it up the other day for testing.  To my surprise I have the same
problem with the other speedoemeter as well.  The difference in speed was
exactly the same as my original speedometer as well.

I am running 195/60/14 size tires in the front, have one of your angle
drives, and one of your long speedometer cables connected directly to the
speedometer.  I was wondering if anyone has heard of any issues like this
with John's angle drives or if there is something else I need to check.

For what its worth, I've been really happy with John's angle drive even if
it might be off a little bit.  I went through 3 angle drives from DMCH
before John started selling his.  Any ideas on what else I could check?
