I just drove my 914-6 from California to Colorado and for the whole trip it seemed to run at a very high indicated temperature. I have stock instrumentation and the temp gauge was almost always in the first shaded red zone (not the solid red zone but beyond the white zone).
It didn't seem to matter if I was in the heat of the desert or in the relatively cooler mountain air. The temperature always seemed too hot. At one point, after unpacking our luggage, this luggage was still hot to the touch in our hotel room one hour after arriving.
Also, at an indicated highway speed of 80 MPH (and this seemed to be higher than actual speed) the engine was turning 4200 RPM. This felt too high. I had a 74 914 2.0 and the engine never felt like it was spinning this fast at highway speeds.
Can anyone tell me what is normal engine RPM at 80 MPH for the 914-6? And what is a normal temp guage reading at a sustained (2 hours or more) 80 MPH?
