Not sure on VW, but according to both Lycoming and Continental below 65% power you can run as rich or lean as you want without danger of hurting the engine, just need to pay attention to the CHT and make sure they are in limits (which running LOP actually lowers the CHT). I have found in my Mustang 2 with an O-360 that backing the power back from 75% power to 65% power and 50 degrees LOP my cruise speed drops from 191 MPH to about 180, but my fuel burn goes from over 7.5 GPH to about 6.25, not a bad trade-off. This is on a carberated engine, not fuel injected with matched injectors as most people believe you need to have to run LOP. My cylinders are generally one about 65 degrees LOP, one maybe 20, and one maybe 10, but as stated, that is no problem under 65% power.

Unless we run it too rich - which does indeed hurt the engine in a variety of ways. John Deakin: http://www.avweb.com/news/pelican/182084-1.html Flying down low is not as efficient as flying up high, but sometimes the trip length doesn't warrant going high. Whether high or low, keep the VW cool and it'll keep us cool. Mike KSEE ____________________________________________________________ Want to place your ad here?
