I'm aware of SDS and I looked at his stuff many years ago and even attempted to contact him, but all the reasons escape me now, but I think I recall that some of what he was doing wasn't really applicable to my project and some of his performance claims seemed to be overly optimistic. However, I just looked at the page you posted and it seems to be new and worthwhile info that I don't remember reading.
Looking at the dates that he posted it though, it is a sobering reminder of how fast the years have flown by....
Once I'm back in the air and looking for places to fly, I think I may just pop over the mountains and pay him a visit.

Todd;
It sounds like your not familiar with your Canadian brother (Ross Farnham) and his SDS company? Many years ago now, he built and flew his “Racetech RV-6A) w/Subie turbo and IVO prop, and in the process did quite a bit of testing which he posted on his web site. See:
http://www.sdsefi.com/rv13.htm
His web site is chock full of very interesting information and pictures, so if you get a chance you should check it out. His P-51ish under cowl radiator cooler on his RV-10 is also very interesting, as is some of the very low profile radiator scoops he has documented over the years.
