    Subject: Re: VG's for a propeller
    Scott, More brake in time could help bring the oil temp. down. Although, as you go to higher power settings you will make more heat, as I know you know. A couple of years ago I was talking to a Stewart Warner rep about a more efficient oil cooler / heat exchanger, of a similar size as the one I have, in order to make a switch easier. He asked me if mine was a single or dual pass. Of course I didn't know. After checking it out, it is a single pass, of course. They do make a dual pass that is very close to the same physical size and much better at cooling. Something you might consider if you haven't all ready. I am near Phoenix, AZ and oil cooling is a problem in the summer. I think I recall that you are in CA, if so then that isn't as bad. I think we are all interested to hear what your max speed / cruise speeds are!

    Yes, Galin, I have been using them for about a year. I can not give concrete proof as the engine was being broken in when I first installed them. At the time I thought I got and additional 50 rpm but would not even try to defend that number. It is too easy to adjust the throttle, altitude, temperature, etc to say exactly what the increase was.
