I flew the SQ2000 today. The engine is running great, now that I have a

seperate water temp sender for the ECU and another for the engine monitor.
The outside air temp was 80 degrees, and I am very

disappointed with my coolant temps. The water temp hit 205 during the

climb.  Temps slowly came back down to 190 once I was in level flight, and
dropped to 170 on short final. Very

disappointing. (oil temps were fine).  I am going to seal all the gaps

around the radiator first, and see if that helps.  I am concerned that the
new ram air scoop I made to bring in cool air to the

throttlebody might be pressurizing the rear of the cowling, and

inhibiting the induction of air through the radiator. I will try sealing
around the radiator first. If that fails to bring the temps

down, I will try removing the ram air scoop and installing a NACA scoop

with a hose to bring air directly to the throttlebody, and not dump it into
the low pressure area of the cowling.  If that

fails, I think I will take up fishing or golf.

Sealing is all important. It was the main subject of my forum at Sun & fun this year.

After a coffee break it occurs to me that the conditions in the plenum and on the oil cooler are such that duct tape will not stick reliably.  Instead use a piece of cardboard held in place
