RPM's at 70?

[stu1]

Just out of interest, I'd like to find out what RPM people's engine's are running at when doing 70MPH.

In my particular case (UK 94 520 manual) it's about 3100, I suspect the larger E34's will be running lower?

Cheers,
Stu.

not 100% sure at 70mph. But at 80mph, I am at 3100. Probly around 2800 or so for 70mph.

My moms 740i is around 2500 @ 80mph. go figure.

535 5speed with a 3.73 diffy - about 2800 at 70mph. If you run the stock diffy - 3.46 - it's about 2300 or so IIR.

My 535 runs at about 2500 at 70mph if I remember.... About 2800 at 75. I just did a 1300 mile trip, averaged 71.5 mph and 23.8 mpg...... I was really happy with that (was diving 80-85 most of the time on the highway, sometime 90 and up, got to love southern cal driving).

My 540i/a runs 100MPH at 3000 RPM with 3.93 gears.....

3K @ 100mph.

3:64

Sorry I meant 2.93 gears...but you guys knew that.

My 91 525i sport manual runs at about 2900rpm at 70mph. The gearing is bang on for the engine, as by nature 24v engines produce their torque higher in the rev range. If it was running a lot lower than that motorway inclines would be problem. The way its set up you can boot it at 70mph and it shifts.

It starts to really come on cam about 90mph.

Your 520i is a couple of hundred rpm higher at 70mph as it need more revs under its belt to make sure it can cope with inclines and overtakes etc.
