Hi guys.
The Glasair SIIRG = is near completion and we are taxi testing.
The OAT is = rising as we enter summer. Yesterday was 37C ~ 100F.
She = can idle forever with water stabilising below 220F and oil below 180F if = the OAT is below 70F but not sure yet about the warmer days.
I=E2=80=99m wondering about 3 options and would value your = experience and thoughts:
1. Route some more air from the = left cheek into the water heat exchange diffuser currently fed by the = right cheek. I am currently only using 50% of the left cheek (Blanked = off). The other 50% of the left cheek feeds air to the engine. The air = is likely not to want to do the gymnastics required to travel the path = available.
2. Install another small core fed by the = available left cheek air with water from the heater outlet. This would = make for easy plumping as far as the water system. I=E2=80=99m not sure = how much heat we could reject from that small diameter heater outlet?
3. Install an electric fan on the main exchanger for extended = on the ground running. Main concern with fan is, what happens when = cruising at up to 200Knots?

Appreciate you feedback
