Time: 20:24:06My Martini Rossi speedo is marked 150mph (white numbers)tops and my 80 931 turbo is 170 tops (yellow numbers). The rest of the guages on the turbo are in green, anybody got a green numbered speedo?
Looks like the speedo was changed at sometime on my 80 for an 82 944 speedo.
From about 1979 the new 170 mph speedo was added to the S market. This is also when the numbering changed from white to green. In 1981 Porsche went back to the easy to read white lettering.
