Top Speed
Hi, I am lucky to have an excellent red block, at 3000rpm it sits at 80mph, which leaves another 3000 to the red line at 6000, I was wondering has anyone ever red lined one and what top speed did they achieve?

Well, the theory says double your 80mph, so 160.
However, it takes a whole lot of extra horses to overcome the massive drag at those sorts of speeds, plus it would probably become quite unstable! Steve :thumbs_up: |

powah
Anybody who's got it past 150 would probably have a higher rev limit than 6250 which is the stock one. Mine's chipped so can go to 6500. I've had it up to 110 and it had a lot more to give with a 15g turbo and V cam unchipped. Stock I would think 120-130. As soon as it's not stock then I think the Volvette got to 180-190?

Speedo
My 760T, my B234F and my Sport (when running right) will all go to about 125/130 - speedo. The speedo in the Sport is accurate.
Surely aerodynamic resistance is a square law phenomenon, so to double the speed you'd need 4 times the power. Conversely if you had double the power you'd go to existing top speed * 1.414 (the square root of 2) so if we say that about 160 bhp gets you to 130, 320 bhp ought to get you to about 180. |
Had just short of 130 indicated out of my old 740GLE (I suspect it was a little bit less than this. 118-120 maybe?)
No idea about the 940. Not even had a ton out of it. |

Another point , the new astra is around 2000kg i read in a newspaper on the weekend , true or not i don't know but that would need 300 bhp to be sporty ! |

top speed
The most i have seen on a 940 is around 138 .

lift
One of the reasons they face lifted the 740/760 was that they got a bit light at the front end when going fast.
