916IS Temps
in 916iS Technical Questions
5 months ago
With the 916IS being so new, there’s limited experience to share, but I wanted to hear from those with a 916 what temperatures they’re seeing. I have a RANS S21 TW with a 916IS and Airmaster w/ 82” 3 blade prop. The oil temps track closely with OAT, so on really warm days (85f) I’m seeing 230f-235f at the top of my climb and 210f on coolant, 112f on Manifold. In Cruise I see it cool down to 220-229f oil, 200 coolant, and 104f manifold at 35in MP. In the winter (33f OAT) I was able to cruise at 9000ft at 38in MP and saw 200f oil temps, 180f coolant, and 72f manifold.
All within the normal ranges, but certainly higher than the 915 in some cases. What are others experiencing?
BTW, the engine is really amazing so far, great performance.
