Tim Yoder" Subject: Re: KIS-List: 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!

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.
