Our speedometers go to 200 MPH - who's been there ?

Telling me I couldn't hit 200mph GPS in my 911R, which has ram air 500+hp, lighter and more aerodynamic, but E92s are hitting 200mph because its some kind of a sleeper or faster than anyone thought?

oh please *eyeroll*

Probably the GPS you are using is not accurate

Can't tell if you're being sarcastic or not, but yes the speedometer reads a lot higher than true speed when pegged...like 10-15mph. Somebody out there must have a video with GPS verification ready to post.

Rut-row scooby...now this thread should really get going

I tend to agree with others on this thread: the difference between going 180-something and 200 is not just a few HP more. Even 20-30 hp is not going to do it. The car would need to seriously decrease its frontal area, meaning taping off all of the grilles and openings, narrower tires, etc. I don't even know how stable the car would be at that speed without more downforce.

I can tell you from my personal experience that the e90 m3 is very stable with the needle burried. (whether that's 200mph or not). Car had kw clubsport 3 ways, te37sl, 295/275 18's. Full interior with 2 occupants.

While the analog meter is fairly accurate with maybe 6kph too much up to speeds up to 150kph, it obviously gets worse with higher speeds. Easy to check with the digital meter set to True speed. Wouldn't be surprised if its off by a good 20+ kph coming towards 300kph, those 320 isch is still really impressive though.

Speaking about power and aerodynamics, the E60 M5 doesn't have crazy power and with a shoebox form it still makes 330kph true speed (mate logged 336kph GPS).

I see you're from NY too. Where did you do 185 at? If you don't mind sharing.

also in belgiums video, thats around 303kph which is 188mph
far from 200mph

again I think stock, the E92 is not capable of 185+ true speed

Negative . Stop the video at 39sec. and it shows exactly 197mph.
197mph is 315.43 km/u .

Of course the true (accurate) speed is about - 15 km/u . That's still 300 km/u ,and pretty fast for our S65.
Even in a Veyron... Balls are required to do it !

For what it's worth, I have both GPS speed and the OEM setup. If I'm cruising at 85 mph per the dash, GPS will say 81 mph. That gap is growing the faster I go.

But me personally, I don't know that I've gotten it above 100ish.

[Pig Farmer]

Has anyone received a red "LIMIT" warning on the dash (and gong noise) when attempting to reach VMAX. The programmable speed indicator is turned off in my car but I got the warning around 155-160. The gong scared the shit out of me.

I have never exceeded the posted speed limit, but one time in Gran turismo the car felt like it had plenty of room left to accelerate at 182 with just the 750 credit stage 1 tune. Believe Gran Turismo displays actual road speed. And that was an E92 not an e90 because you can’t get an E90 in gt5.

It’s a pretty aero efficient car (not very big, low .30’s cD) and with all the horsepower happening at redline and redline right at vmax (for the 6speeds anyway, dct has to drag that taller 7th) so it makes some sense the game designers would not toss this out as implausible. In gran Turismo. The video game where this happened.

Riiiiight Gran Turismo....

The sound definitely isn’t right but hey still better than the original. No escudo though.

[codinge90]

Not related to top speed but I've hit the speed governor on my car and got radar signal on my radar and escort 9500 showed me at 155. Electronic speedo showed 170. I know I was definitely at that governor though I felt like a dead spot when I hit it. These cars are definitely optimistic with what it shows electronically or on the actual speedo itself.

I'm coming at you in my Renault espace f1.

Drag is proportional to the square of velocity. Going from 40mph to 80mph is 2x the speed, so it is 4x the drag... Now, the power required to overcome the drag is velocity cubed. So going from 40mph to 80mph requires 8x the horsepower... say from 10 to 80.

Lol at people thinking a stock M3 can do 200...

A F430 coupe with more power, less weight, and way better aerodynamics can barely crack 196mph. Why would the E92 M3 which is inferior in every relevant category be able to do better with less?

[spazzyfry123]

You guys are tugging at my heart strings with these Gran Turismo references. I was GLUED to that game as a kid.

Remove your topspeed limiter . And I'm pretty sure you can hang on the F430 tail ...
Note : I'm talking about topspeed .

Have you played the new one? It's ok, not as addicting as the old ones, but I have a ton of fun with the livery editor. Made some of my old favorites, and adopted the 90's oreca theme to a mustang.

The BMW installed speed limiter kicks in at 155 mph. That is not what prevents the M3 from hanging with the F430 in top speed. What keeps the M3 from staying with the Ferrari is greater total aerodynamic drag coupled with less power. It's as simple as that. Superman may be able to fly on the big screen, but in real life the laws of physics get in the way.
