M6 top speed run
Does any one have a top speed run on a k4 car that we can compair this to.I kinda don't believe that k4 M6 video and would like to see if some one could do a top speed pull with there car.
I have been on this high way in Greece and is kinda an up hill road and you can hear them talking about it in the vid also.
the car has 3 people and a software flash in it.So it is not 100 % stock.I think it might have an exh also but not sure.
either way the mods can be a wash since there are 3 poeple in the car and on a up hill highway.
check it outhttp://videos.streetfire.net/video/1e8abd95-9afb-42f1-b2f9-980900405e28.htm

I know the cars are capable of doing it,I just wanted to see how fast they pull after 120-200 mph
wich is where the M6 started gaining really fast in that video

The M5 and M6 have the following gear ratio / torque multiplication (product of gear ratio x rear end ratio) in gears one through seven (per Road & Track):
1 - 3.99 / 14.44
2 - 2.65 / 9.59
3 - 1.81 / 6.55
4 - 1.39 / 5.03
5 - 1.16 / 4.20
6 - 1.00 / 3.62
The E55 has the following gear ratios/torque multiplication in gears one through five:
1 - 3.59 / 9.51
2 - 2.19 / 5.80
3 - 1.41 / 3.74
4 - 1.00 / 2.65
5 - 0.83 / 2.20
This means that M5/M5 gearing provides the following percentages of the E55's torque multiplication in gears one through five:
152%
165%
175%
190%
191%
That is quite an advantage. So, how, you ask, does the stock E55 manage in the videos we've seen to keep up up to until about the time the M5 hits fourth gear?
Because the E55's engine in stock form produces about 147% of the M5's torque (using dyno numbers here, not the laughably low numbers from Benz), which helps it in the lower gears, but once you get that jump from 175% to 190%, things definitely pick up.
No magic, just a better match of gearing and engine for high-speed acceleration in the M's case. Close ratio trannies are da bomb up high, but they cost you some gas mileage. It's all about tradeoffs.

M6s and M5s pull very hard up high, no doubt about it. There is a reason for this: physics.
