Spitfire II quirks, questions and anomalies

[Danelov]

Yes, the Spitfire had this boost but is not automatic. In the time pilots speak about of :"Breaking the wire","pulling the plug","Buster", "thought the gate" ,"Pressing emergency overide","press the emergency boot tit", etc, etc.
"Breaking the wire" refers to broken the protection wire in the throttle quadrant to limit the overpower and ev damage to the engine.
