Hi David
That may wel= l be what will be needed in flight. At present we have the gear door open o= n the ground so plenty of exit.
I=E2=80=99ll do a search for SS l= ouvers in prep.

Thanks.

Hi guys.
The Glasair SIIRG is near comple= tion and we are taxi testing.
The OAT is rising as we enter summer. Yest= erday 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 cu= rrently only using 50% of the left cheek (Blanked off). The other 50% of th= e left cheek feeds air to the engine. The air is likely not to want to do t= he 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 hea= ter outlet?
3. Install an electric fan on the main exchanger for extende= d on the ground running. Main concern with fan is, what happens when cruisi= ng at up to 200Knots?

Appreciate you feedback
