Mine used to get up to just under 185mph, but fell back to around 170mph after I changed spark plugs. I had been using Autolites, but switch to the recommended Bosch plugs. That was a bad idea. I reinstalled the Autolites and gapped them at .065 and managed to get back to top speeds of right at 185mph.

115 mph would be about the limit for the six cylinder. |

Model? Engine? Why was the work done?
No W126 that I'm aware of will do 155 mph (are you in Canda -- kph?) Peter

If the problem started after you had work done, why not take it back?
How big is that crack in your windsheild? Glad to know someone is holding a video camera while driving 120 mph ![]() Where do you live?

The early 500SE/SEL's were indeed very fast. I rode shotgun in a '81 500 SEC in '84 heading west from Munich to Stuggart and we easily cruised at an indicated 250 kph. The owner said at the time that his car was produced before MB changed the rear axle ratio. From my technical data book I note that the ratio was changed in Sept. '81 from 2.82 to 2.24, a very meaningful difference. While the earlier car would pull redline in top gear the later one would not. We owned a Euro 500SEL that was produced in 1982 that my wife drove as a replacement for a very rusty Euro 450SEL. She frequently complained to me that the 450 was much quicker than her 500 was and peladed with me to resurrect the 450 (she was a very fast driver). Also, keep in mind that the later 500SE/SEL had a taller rear axle ratio than the 560SE/SEL did (2.47). In short, I believe that egutie's 500 could run 155 before the shop work. One question for egutie, was the front cover removed to replace chain rail guides? If so, did they mistime one or more camshafts and/or ignition timing (Euro ignition timing is 16 deg. +/- 3 BTDC with vacuum connected at idle)? Mark

Oh yeah I remember you form MBworld. Racing in traffic, blowing up your engine...with kerosene in it.
![]() Did they change the timing chain or just re seal the front cover? If they changed the chain they probably got the timing off a bit.
