Aboukir air filter on Spit V - performance?
Of all the kit that has been hung on Spitfires, nothing seems to have attracted as much dislike as the Aboukir filter.
Does anyone know of a source for the details of how badly it cut Spitfire V performance? What was the ram recovery ratio (what ratio of possible air intake actually makes it into the supercharger – 50% for a basic Spitfire IA)? What did it add to overall drag? Thanks, David Isby
