Does anyone have informations, specs, drawings, etc. of the unbuilt Allison V-1710 F24 engine???
On page 272 of "Vees for Victory", his authoritative book on the Allison engine, Dan Whitney states "this engine (F24R) would have used a newly designed integral two stage supercharger". That choice of words makes the F24 supercharger sound temptingly like a Merlin 60 series 'blower'. My speculation is an 'integral' two stage arrangement could be a much more compact package than the (fairly) well known two stage mechanically supercharged V-1710s using the Allison Auxiliary Stage arrangement.
