The brown car at Castle Combe in 1993 was supercharged I recall and looked and sounded great and I think the bulkhead was modified to clear the supercharger. Great to see photos - any of the engine bay Colin?
I believe I saw the pale blue one in a workshop in Turin in 2006 when it had a 2 litre engine with, I think, a twin Soles Nardi conversion. If my memory is correct, this car was built on a 1st Series floorpan.

Following on from Wills B10 thread and mention of Citroen Traction Avant wheels being modified to fit the Aurelia ( I think I still have a couple of same in my garage roof space), on browsing ebay I came across this, then checking further to find Chris's mention of a supercharged B20, would this version of a supercharger be suitable for an Aurelia engine?
