Spit Mk1 Boost?

[=XIII=Wedge]

So given that we currently have an earlier Spitfire using only 87 octane fuel:-


With the ABC enabled (normal situation)

• The maximum boost obtainable will be +6.25 lbs.
• Once set the selected boost (datum) will be maintained regardless of changes in altitude up to the rated altitude.
• Above rated altitude the pressure will drop off, but the datum point will remain the same.
• Pilot workload is reduced and there is no risk of overboosting the engine.

With the ABC disabled (done by operating the cutout)

• The maximum boost obtainable would be +17 lbs @ sea level.
• Any rise above + 6.25 would have disasterous impact on the engine due to pre-ignition of the fuel.
• Provided that the pilot retarded the throttle they would have manual control of the boost, but would have to be careful not to overboost the engine.
• The indicated boost pressure would change as the altitude changed.

Assuming that this is a correct description then from a game design point of view their are a few options.

1. The operation of the cutout would only be of value if the game simulated failures to the ABC unit either through the damage model or the physical weathering setting.
2. If this was not the case then the cutout option could be removed (Only the sadistic would take pleasure from using the cut-out to intentionally overboost a Merlin)

If any of my assumptions are incorrect then please let me know.

Does this seem like a reasonable analysis of the issue?
