Mud Posted April 23, 2020 Posted April 23, 2020 (edited) In a chart of Chucks guide you can see that for max range, an RPM of 1800 is used at around 3500 feet. When I fly at that setting, with a boost of +0 and weather set to +12°C, my coolant temperature is around 49°C only. I did manage to fly from the UK to France, then increase RPM and boost for combat, and then fly back on the economic settings without any issues. Questions: - Is the low temperature normal a bug? - Is it harmful for the engine to run at those temperatures? EDIT: I actually see the chart is in the DCS manual (page 144) Br, Mud Edited April 23, 2020 by Mud Spoiler W10-x64 | B650E Gigabyte Aorus Master | AMD Ryzen 7 7800X3D | Noctua NH-D15 G.Skill Trident ZS Neo DDR5-6000 64Gb | MSI RTX 3080ti Gaming X Asus Xonar AE | VPforce Rhino + TM Hotas Warthog MFG Crosswind pedals | Valve Index
grafspee Posted April 23, 2020 Posted April 23, 2020 There is couple of issues with low temp. Mainly is the spark plugs fouling and risk of engine not respond to to power change in right time. This is issue with Spitfire in dcs, it is missing thermostatic valves for coolant and oil systems which allow them to over cool. IRCC thermostatic valves should cut off radiators below 60C or 80C. But its not here yet. As you can see Spitfire has big ass radiators under each wing, additional to this radiator doors when fully closed are almost fully open, they may cover 3/4 of flow area. With out thermostatic valve simulated you will over cool engine even at much higher power settings in cold temps. I had engine overcool in Spit at max cruise setting which is 2650 +7 boost System specs: I7 14700KF, Gigabyte Z790 Aorus Elite, 64GB DDR4 3600MHz, Gigabyte RTX 4090,Win 11, 48" OLED LG TV + 42" LG LED monitor
