I will be going on a small trip for me but a seemingly long trip for my VW. It has a single port 1600, appearing to be all stock. I have aftermarket chrome half moons but the tires are just a little wider than stock. I also don't have a tach and other than me, I will have about 100 lbs of gear. So, for this 200 mile trip(one way) up and down a few hills during the summer, what is a safe cruising speed for the engine? I drove it 350 miles straight from Tucson to far West Texas at about 62/63 mph it over 100 degree temperature last year. Didn't seem to hurt it. So what do you think?
