Spit 2a overheating...

[IvanK]

Spit IIA Oil cooling/temp rise versus Pilots notes limits is currently porked in this patch. This came with the New (correct) true +9Lbs Boost availability with Full throttle. Note the Boost gauge scale only goes to +8.

Has been reported directly to Devs with all documentation sent. Suggested as High Priority fix.

Oil Temp rise is just way to quick on Spit IIA that results in engine damage. Oil Temp indication is Inlet Temp. Spit MKIIA Oil temp Combat limit is 5 mins at 105C, Normal Climb limit is 90C. A Climb all the way to 30,000ft at +9/2850RPM should be possible without any real issues with Oil Temp rise. Attached JPG of RAE Climb Oil cooling test trials illustrates this. Devs have this info.



Hurri info attached here as well. As you can see Hurris is not even a remote issue with Oil Temp rise. I guess a better Oil cooler I guess coupled with being in the radiator bath so rad flap area has a greater influence in cooling.



Tip for the moment. Forget the MKIIA. Use the MKIA You can easily climb +6/2850 Rad open all the way to 14,000ft with Oil temp only just getting up to 95C.
Note for the record IRL Spit IA Climb limit Oil temp is meant to be 90C at +6/2600 with a 5min combat limit of 95C.

(On a side note there was an issue with Classic IL2 in that the cockpit gauges showed Inlet temp whilst the FM/EM used outlet temp so conversion was required to get usable cockpit indications when the cooling routine was re done in ver 4.10. I am not sure if this is a similar situation in COD)

Great info, IvanK. Thanks for posting this.

Good info there Ivan thanks. It does seem from the pilot notes that such a climb should be possible with a closed or slightly open radiator. Would you agree?
