'06 E55
We are still unsure why some TCUs will allow a massive burnout while others won't. Some later model cars will smoke them like crazy. Here's my '06 going through two gears, no brakes. I was in "M" mode and forgot to shift, which explains the rev limiter bounce:

Burnout, straight line acceleration, top speed....the E55 would rape an SC'd E39 M5 all day everyday. The E39 M5s with supercharger struggle to beat the E55s stock quarter mile record. That's so sad.

My car will just shift at redline... whether in M-mode or S.
Is this because mine's an 04 and the TCU's are different?
But the E would not rape a Supercharged E39 in straight line or top speed...

I actually just watched the video now 
Jesus Christ, that E55 looks facking TOUGH!!! 
It made the E39 M5 look like a coward *****. That E55 looks so facking sexy No contest regarding the burnout either, I think the E55 shifted into 3rd during the burnout. TORQUE!!!
You're right, it wouldn't just be rape, it would be murder....hell it would be GENOCIDE. The E55 has better aero and alot more power potential. The E55 hits over 200mph stock and modified it has hit 219 mph. There was a thread here a while back and a guy from Abu Dhabi posted a video doing 342 km/h which is 212 mph. The E55 is a top speed monster because 5th is geared tall and the car is extremely aerodynamic and has insane power and torque. It would annihilate a supercharged E39 M5. It's not even close. You would need a supercharged E60 M5 to beat it in terms of top speed and that would only be because the 7 spd V10 M5 is geared for alot of top speed. An E55 with a motor like the one Ahmad has in his car or the one RedBullJnky has or the one e55amgrocket has would get to 230-235 mph with the right gearing, say if it had a 7 spd gearbox with a tall highest gear.

So statistics are bullsh*t to you? Statistics run the world, in everything from economics to science. The E39 M5 has no chance, this is a fact. Not my opinion. I had an E39 M5, I love the car, I love the engine and the the looks and the inside and the feel. The car is slow, NA or supercharged. The E55 is a monster, there just isn't a comparison between the 2 The E55 is not a perfect car, there is ALOT I hate about it and would change. It's a fact though that the E55 is an insanely fast car with alot of potential. Show me an E39 M5 in the 10s... If that's bench racing then I guess I'm on the podium.

Stock or not stock E39 can't keep up, even this supercharged E39 would have problems with a stock E55 on straight or 1/4 mile

You replied to MTV10 with dyno numbers when he mentioned an E would not "rape" a S/C E39. As I have no experience with the M5, I'll take your word that the E will still win, but it will not be a rape.

I was referring to all of your top speed number claims. Besides the one video you mentioned, of which we have no idea how accurate his speedo was, do you have any proof to back up your estimations? By your numbers, a modded E55 is getting close to running with a Veyron.

That 230 mph claim was if the E55 had the right gear ratios and a 7 spd gearbox. I never said an E55 can do it with it's 5 speed and stock gear ratios and diff ratio. I said the power and torque are there and so is the aero. I made the claim because the G Power BMWs have done that and they have similar power figures, therefore it's logical to say that IF IT HAD THE RIGHT GEAR RATIOS it could match their speed.
I remember at the time that guy sent me another video where they had a vbox and they were doing a speed run. It's on my old computer I'll try to find it and post it on YouTube. The speedos are pretty accurate too. They match GPS pretty much perfect. I did 176 mph once and my standalone GPS unit was the exact same speed. I don't know where this idea that all speedos are inaccurate and read 15% higher comes from.

There's a general belief on the internet and in the real world that car speedometers are inaccurate. People always dismiss top speed runs where the car's speedo was used to back up the claim as inaccurate and overrated. If an E55 says it's doing 342km/h it might be doing 339 or 345 but the margin of error isn't going to be more than that. Why should the margin of error increase as speed increases?
So my point is, that video of the E55 doing 342 is probably quite accurate. The E39 M5 just doesn't have the aero and the power that is required to do what the E55 can even if it's supercharged. Nothing wrong with that, the E39 M5 is a very fun car and while not frighteningly fast it's not exactly camry slow. My point is the E55 is in a different league. They're just not comparable.

Because speedometer errors are not linear. When a speedometer is inaccurate, it is off by a certain percentage. The higher the speed, the higher the differential.
Lets take a tire size that is not stock, for an example. Listing the 265/35-18 as the baseline, a 265/40-18 would be off by roughly 4.1%.
When running the new tire size and your speedometer says you are traveling 50mph, you would actually be traveling 52.06mph. When the speedometer says 100mph, you would actually be traveling 104.12mph. At 150mph, you would actually be traveling 156.18mph.
If the error were linear, the speedometer would be off by the same amount, no matter the speed.
