The Late John Muir in the idiots guide to rebuilding aircooled VW's wrote alot about this subject and I think it is still relevant for the waterboxer. If you can get your hands on a copy it is well worth the read. Roughly translated, it's an answer of listening to your engine. Warm it up before you drive (I think most of us let that one slip), don't over rev it and maybe just as importantly, don't under rev it. A classic example is lugging up a hill at low revs with your foot flat to the floor in a high gear. Change down and give it moderate throttle so you feel you have power in reserve. I live at the top of a very steep hill and there are two ways people seem to tackle it. 1. rev out in first, second and lug in third 2. ease it out in first and coast up in second. Listening to the difference, you have one engine that screams and then strains and another that sounds like its working but coping easily. The time difference is about 4 seconds.

(more data please!) that said........... What would the "best way to drive" your rebuilt Waterboxer be? Is there particular RPM, acceleration patterns etc which are better for the motor than others?
