wow, loads of info on that one!!! that site is nice to learn from!! That bike is using a 500 carb!
could you imagine if a small turbo was manufactuired for a 126, even if it was a very small one, the smaller the faster acceleration and bigger the turbo the high top speed you can gain.
all sounds very nice but Barry & Slater are right, far to un reliable at present, the porsches used aircooled engine untill mid 80's i believe. Interesting subject though.
