Hi guys.
The Glasair SIIRG is near completion and we are t= axi testing.
The OAT is rising as we enter summer. Yesterday was 37C ~ 1= 00F.
She can idle forever with water stabilising below 220F and oil belo= w 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 th= oughts:
1. Route some more air from the left cheek into the water heat e= xchange diffuser currently fed by the right cheek. I am currently only usin= g 50% of the left cheek (Blanked off). The other 50% of the left cheek feed= s air to the engine. The air is likely not to want to do the gymnastics req= uired to travel the path available.
2. Install another small core fed b= y the available left cheek air with water from the heater outlet. This woul= d make for easy plumping as far as the water system. I=E2=80=99m not sure h= ow 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 ru= nning. Main concern with fan is, what happens when cruising at up to 200Kno= ts?

Appreciate you feedback
