I think we need Marshall to chime in here with official top speed numbers. I am almost certain I saw 102 for the SD, which means I have a hard time seeing yours going 115 - not saying you are lying, just wondering what's not right here - maybe my car and my firgures...? Anyone got official figs and if SD is 102 tops, why does Luther's go 115...wrong size tires?
Officially the top speed for 617.95 powered cars was 165-170 for the 123s and 170-175km/h for the 126s (5 km/h slower BEFORE 1985). That's 109 mph for a 1985 126.120 300SD and 106 mph for a 1985 123.133/153/193 300D/CD/TD.
I know that doesn't make a lot of sense when you play with the gear ratios, engine speeds and tire sizes, but those ARE the number Mercedes publishes. I know of more than a couple of 126.120 and 116.120 owners that have exceeded 110 mph (numbers from 113-117 come to mind) in situations where they were clocked with GOOD equipment. It seems that while staying within the outside edge of the allowable specifications you could exceed the published top speed by about 7%. Maybe that requires a tailwind.
