How many of you have opened up your M5 all the way? I've gotten up to about 150 twice, and was still accelerating, but ran out of road. I routinely hit 120.

What's the fastest you were ever going when you got caught? Ticket? Jail? I haven't gotten caught in my M5 (Thanks V1!).

160 MPH on the speedo and still pulling in fifth. I was approaching some cars, so I had to back off. Felt stable and smooth.

During the trip to Germany we went so the limiter hit in about 20-30 times maybe during the trip. The limiter is "softer" when going in 6th gear than when you hit the limiter in 5th gear. Also, it indicated 270 km/h om the M5 speedometer and 265 km/h on the M3 speedometer. Then the speed on the M3 board computer (an unlocked function of the on board computer) was 256 km/h or sometimes 257 km/h.

Sometimes the M5 was going faster, sometimes the M3 were going faster.

If you see on the preview I'm chasing a E39 M5 with 260 km/h on the speedometer and the M5 was about to brake, so I had too get rid of the camera quite fast. The difficult part wasn't to drive fast, it was to take a good picture in the same time.

After we removed the speedlimiter on the M5's there was of course no chance for me to keep up.

Also, we went with the Nowack M5 over 300 km/h on the tacho with 5 people in the car without any problems.

I've one without limiter and driving quite often up to the limit. On flat street it ends up on the meter at about 305-310km/h. When it's going a little bit downhill I got it up to approx. 330km/h on the meter when the rpm limiter hits me. The needle on the meter was exactly on the "h" of the km/h mark.

Well, acording to my calculations, with stock tires and the stock gearing a 7000 rpm put to the shaft of the gearbox will turn 329 Km/h on the wheels. Can anyone confirm this. I know there are always some frictional loses but the only point were i can figure rpms lost is the clutch. How much could be lost there. I know the E30 M3 Evo had a 3% loss on clutch at max speed of 248 Km/h. What's up for the M5 ?! Those 329 are surelly exagerated, but then were those rpms go?!?!?
