BMW speed limiters...

[granville]

...don't seem to be terribly effective.

God in heaven!

[Marki]

So what did Herr Munchengobler do vmax

[jeremyc]

Ah-ha! Something of a Bruntingthorpe dilemma for the Earl?

No worries: have your man drive one of the chariots and give them both a good thrashing.

Good work my man - keep it up.

[granville]

Must say, Jezza, the brakes are pretty sh1te though!

[dazren]

Oh dear.

friend of mine has an M5 which has been derestricted, apparently it went on the gumball and was seen in excess of 180, i think it will be coming on the next Brunters Jolly...........

Excellent. Any idea on dates yet?

DAZ

[craigw]

no, I'm hoping mid-late march, still waiting on dates, apparently they have a very special vehicle launch and the dates for that havent been confirmed which is mucking things about a bit. Not sure what the car is, I'm guessing maybe Ford GT or Porsche Carrera GT.

By the way, I have been approached with regard to a tv company filming our next little jaunt, would anyone have any objections ?

I can see a few downsides to this. YHM.

I always wondered what my ex XKr cabrio would have done if derestricted , comeing over the Oresund bridge between Sweden and Denmark there is quite an up hill gradient , but top down she would pull like a train up to the 250kph limit in no time and then just bounce off the limiter .

[craigw]

I have replied Daz, I had the same thoughts, will discuss further.

[m-five]

On the autobahn, my 94 e34 M5 will do 180 on the clock in 5th, but only 160 in 6th!

[craigw]

weird, is the limiter only on 6th gear then ?

[Ultimasimon]

No, 6th gear is an overdrive as such, and the engine does not have enough torque to pull it through the rev range in top gear.

[Patrick L]

so what sort of rev's are we doing in 5th at 180mph?

[craigw]

aha, Mr L, wondered when you'd show up.

[veetwin]

M3Evo 6-speed Getrag box obtains vmax in fifth due to the ratios. 6th gear is 0.83:1 IIRC therefore and overdrive as such.

My limiter didn't seem to work as I acheived 165mph on the OBC by resetting every couple of seconds by the missus.

I found out the reason behind the nominal limiter fitted to most German vehicles capable of such performance; apparently, the limit is set to acheive tyre noise limits. Anyone else got any info on this???

About 7200rpm - I'm guessing the actual speed was 165 or 170max

Chaps, how does Sunday 21st March sound for V Max IV ?

I'm up for it - assuming I'm not working that weekend - although I won't know that until Friday 19th March knowing the way the system here works.
