I'm new to this forum. I live in New Zealand and I own a Just Aircraft SuperStol with a Rotax 912 Vz turbo with 135 hp. Refer to this URL to learn more about the engine: https://www.912turbokit.com/copia-di-fly-120hp
According to the company that converts the 912s to a turbocharged version I should aim to fly the engine no higher then 90°C and never ever exceed 100°C. I cannot evaluate why these numbers but that's the given advice for longevity of the engine. I'm struggling to keep it in this range when climbing over 6000 ft mountain ranges which I do often around home. I can't make use of the power I have available because I'd be exceeding these temperatures.
How can I increase the cooling capacity best? Should I mount a bigger radiator for the cooling liquid or a bigger oil radiator?
I'm about to fit an 85°C thermostat so too low temperatures should not be a problem.
Thanks for advice on this!
