Hey MiTasol,
The literature I have says that any of the 'F' series from the VIIF on (ie VIIF, VIIIF, IXF, XF) could be fitted with the supercharger. The non-'F' series of these same Marks were not fitted with and were not listed as available with supercharger. I assume the Jupiter VIII and IX manual you you have is for the non-'F' series?
For sure the VIIF and XF series were actually sold and operated in service with the supercharger.
The VIIF for example was used for the altitude record flights, and was used on the Bulldog Mk IIA among other airframes.
The XF was fitted to the HP.42 (XFBM?) among other civil airframes.
The French fitted the Gnome-Rhone license produced Jupiter VI with a supercharger, although I do not know how much use it saw.
