If the timing is wrong there is a lot of power to be found by setting it correctly.

Yes, having your timing retarded will generally reward you w/ better top end power..thus you use the ideal compromise seeing as these are street engines.

M117's (560's in particular) like 12-13 degrees initial timing as specified by the factory and even AMG seems to like that setting best. Take a US car to the dyno and pull the ignition resistor (giving you your full initial advance). If the rest of your engine is in proper running order you Will absolutely see HP gains. As for the 420 EZL, if I would be surprised if it runs more timing w/ the resistor pulled.. Next time I have a 420 in I’ll play w/ timing/resistors/EZL’s etc and see what I find.


As for comparing a lexus to an SEL, the lexus has a few advantages, one it automatically starts in first gear.. engaging first in our cars changes the character dramatically. 2nd, I wouldn't be in the least bit surprised if the lexus had a steeper diff..a Lexus was never designed to run all day @ 120+ so more aggressive gearing makes absolute sense.

As for how a car is driven, if you maintain a Mercedes properly the car will make good power for a long, long time.
