THEMA: 280S max cruising speed?

Geschrieben von Clem am 20. November 2006 08:26:26:

Hello everyone,
Does anyone have any thoughts about what the maximum cruising speed is that it is acceptable to run the 280S / SE engines at? I am not used to engines that rev so high and above 100km/h it starts to sound quite busy in the engine bay. At 130km/h the engine sounds like it is really revving quite hard and I worry that it is perhaps not good for the engine. I did read somewhere though that these engines were designed to run at high revs. Any advice much appreciated.
Regards,

Clem

because of the unlimited speed on the german autobahn, they are designed for continuing maximum speed. (Exept the 250 - they had some problems with it)

I know, they sound horrible then, but the early engines wher designed for high rev's. Reffering to the age of the engines, with 150 km/h continuously speed you stand on the safe side!

Hi Clem, the most pleasant cruising speed, in my Opininon would be the speed that is the limit of the 2nd highest gear plus 10%-20%.

In my Finntail for example the 3rd gear ends at about 100 km/h, so travelling arround 120 km/h in the 4th gear is the most pleasantly way to travel.

You are not too slow between the modern cars, the noise is within limits, and during longer travels you're still fast enough to reach the destination within a reasonable time effort.

Acctually on long distance travells I noticed moderns cars passing me several times on the Autobahn, cause they made a stop for what reason ever and I didn't.

Thus that the travel time difference becomes very small in the end.

Hello Clem,
my own 280S of 1971 didn't ever complain if I was in a hurry a little bit ...
I never had any problems at an average speed of 170 km/h during more than two hours (ok, I've HAD one problem: my car guzzled more than 22 Litres of 98-octane-fuel at each 100 km!)
If the car is in a good shape, it shouldn't be a problem to push it to top speed and hold it there.


You should REALLY try that at home! )


Regards,

Robert

Thanks Robert. The car is in very good nick so I'm going to wind it up sometime and see how it goes. The important point though for me is that I can run the machine happily at 120 or 130km/h with no worries. That I needed to know!
Cheers,

Clem
