My knowledge on these matters doesn't approcah yours, all I know is that despite the different engines and boost levels, above a certain altitude meant the planes were similar in speeds. Thanks for the explanation Viper.

Where you doing the tests with CEM off? I ask beacuse when I tested without CEM I was able to get 388mph at FTH with the Spitfire IIa in CoD.

I noticed this as well, I mentioned it on one of the other threads. Here is the post I made on this.

The alternative explanation would be reduced airframe drag.
Anyway, R.M.2.S. was an interim rating for the Merlin III prior to the introduction of the +12 psi combat rating; the Merlin XII was a somewhat different animal designed for +12 boost from the start and would deliver about 1165 bhp at sea level and +12 psi, and takeoff power of 1175 bhp at +12½ psi boost.
It seems to me that more testing is required, both with CEM on and off, especially given that the sim has been quite extensively patched in the last 20 days...
It is also important to remember that whatever results we get from the sim need to be corrected to standard conditions before they can be directly compared with historical test reports.

Absolutely agree, the Spitfire Mk IIa shows +8 lb boost and gets speeds similar to a +12 lb boost version. I stopped testing when I realised the high altitude FM or CEM was broken. I feel that further tests are needed once the devs fix the previously mentioned issue.
