Anyway if the gas engine is turning 3200 at 70 that seems like it would be just fine with the diesel. My '83 760 D24T with stock size tires and stock gearing turns about 3400 rpm in overdrive at 85mph, which is still too slow to keep up with highway traffic here. But it seems happy to do those revs or more all day, in fact it seems to be capable of quite a bit more, although with the 1983-only 85mph speedo I am not too tempted to explore. Really the ability to rev smoothly and provide a wide power band is one of the neat features of the old IDI turbo engines, and makes them fun to use for hard driving. The later direct injection engines are much more limited on the top end, although their low end response is better. They seem to pretty much run out of breath even before 4000 rpm.
