Its the +12lbs line achieved using 100 octane and boost cutout override that we hope they are working on because without it we don't have the BoB. We have "thank god they didn't come in November 1939".

Klem, I agree totally.
So to summarise as I understand it, we currently have a Spit I that has low alt performance about right for boost controlled at +4 psi (although the gauge reads +6 1/4 psi, the correct boost setpoint for 87 octane). The new plots suggest that this performance might be degraded in the patch to about equivalent to if the boost controller setpoint was +2 1/4 psi. Of course this leaves aside that frontline BoB Spit Is had 100 octane and a modified boost control cutout that increased the boost setpoint to +12 psi, and we don't know if the devs have any plans to fix that.
B6 if this is correct, I don't think the Spit I will be useable in MP, it is almost unusable now.
Wouldn't it be cool if the Spit I and Hurricane boost cutout actually worked? Incidently this would tell us the octane number of the fuel in those virtual tanks.
If they are unmodified and running 87, pulling the cutout at full throttle on the deck would give an instant +17psi boost. The engine would make horrible noises, lose power and become damaged in short order. Sneaking the throttle up tells you the octane, if it starts making the predetonation plinking noise (that the game seems to model) at around +7psi, it is 87. +12 psi, it is 100 octane. Greater than that, it must be 150 octane (seems a bit unlikely
). Of course with 100 octane the boost cutout should have been virtually modified so that it is no longer a cutout, but instead controls boost at the higher +12 psi value.
The boost cutout in the Spit II is a bit strange, it just unlocks a bit more boost but clearly it has 87 octane inside as it starts to predetonate at around +7 psi.
EDIT INCORRECT STATEMENT with mixture/ rpm changes the Spit II will sit happily on +9 psi and go 320 mph IAS/TAS on the deck So it models 100 octane boost behaviour.
But if we have to have to use Spit Is and Hurris in their pre-Battle of France fuel configuration, the original (working) boost cutout would be fun! People would be using it to squeeze a little more power from their 87 octane but blowing up motors left right and centre. A bit arcade I know but I would love seeing it in MP. Perhaps a server side setting would be useful if you didn't want it ("crew chief secretly used extra thick wire on boost cutout after what happened last time" setting).
It is a problem that WEP configurations for combat edge carry little penalty if modelled correctly..because the problem is for the virtual erks or the next guy that flies your plane if problems are not addressed. Again most people would consider it arcade, but I would love to see that if you used combat concessions, you are that "next guy"...engine wear is accellerated over reality to "simulate" that effect. People would only use WEP configurations if they really thought their virtual life was in danger or interception was critical.
Well, you can dream,

BTW Ramstein, great post on engine stuff
