New 2012 S65 AMG Top Speed
Congrats on the S65! As you found out first hand, it's a beastly car.
That said... you mentioned this car is new and you're winding out the motor that hard so soon. That's probably an ill-advised combination. If it were me, I'd really lay off the whole-shots for a while. There is a prescribed break-in for these cars which I really would follow carefully.
Secondly - you mentioned a 186 mph governor. You've got the 030 or performance-package installed on that car, methinks. The only way to break through that limit (I can't even conceive of 186 mph being a limit save for that of physics) is to swap the ECU. I have it on good authority that you really want to trust the big guys on these, and not go with one that is a work-in-progress.
There is a way to defeat the ESP. Historically, ASR is put into diagnostic mode and run normally - that's how those ASR defeat switches work. In the newer cars, ESP is integrated within the ECU (as I understand it) and tapping or shorting out pins doesn't work any longer. Therefore, that too has to be coded within the ECU.
Terminal velocity on W220 S65s is estimated at 195-200 mph or so. W221s should be similar. For comparison, terminal velocity for an S55 is about 180-185 and S63s are about 190. When you find it, please post, but by the grace of God, don't get dead!

OP, get an ejection seat if you plan to take your beast to those triple digits again. No roll cage will save you!
But whats an Ejection seat gona do if its ejects him when the cars in a roll . . . . trust me you dont want to be ejected while the cars upside down.
Iv had my car upto 175mph on a track, several times within the space of about half hour. But atleast one of my tyres has a puncture repair and nearly every idiot told me it was too dangerous, but rather than just read about it somewhere i think people should get out and get more real life experience. Most people who write this kind of stuff are too prone to Health and Safety rules and go way too far into the safety zone incase they get sued. people like me usually prove them wrong.
I know what your referring to with the eject seat, and it would be a cool feature to have, but just as your referring to Bond in this case, i was referring to Hot Shots where he ejects from the fighter plane and ends up going through the bottom of the plane thats directly above him.

Didnt look as cool as Bond to me, lol.

Iv never had the pleasure of driving, or been driven, in an S65 but from what i hear you cant really tell what speed your doing as it always "feels" slower than the true speed. Maybe the OP felt he was only doing 86mph




Sorry to rant.
In short, most busy US highways.
In Germany (and selective highways throughout Europe, France being my preference), going fast is no big deal and definitely NOT dangerous. In fact, the Autobahn is the safest place in German traffic, or US traffic for that matter.
We used to drive a Ruf Porsche Turbo (friends car) at 200+mph and it was safe, wicked fun.
That said, I wouldn't take any S-Class over 186mph for any extended period of time. It's too heavy for the tires to put a lot of stress on it, especially in curves.
Check out my S65 that I have. Congrats on yours though! You will have fun with it.
A simple tune will take the limiter off. (I recommend Eurocharged because of their customer service and no MB tax).
It is going to be difficult to find a safe place to test the high end because you will need at least 2 miles to achieve this.
I am assuming with a tune that you would do the mile at around 170mph. It will go up very slowly after that. There is an event in Texas where you drive on public roads and the roads are blocked. I think this could be a great one to test your speed and your *****
.If you buy top brand tires made for for high speed (Z rated with an 88W or 99Y added to it), the tires will handle without issues the speed you are trying to achieve.
