Um. Holy [goofydrunk]Hey guys, there is a supercharger bolt on for the Duratec 2.0lt. Caterham in the UK use this engine with a supercharger for their open wheel car. I'm sure that we could get the super charger as a part and bolt it straight on.
Have a look at this link and open the specs Seven 620 R | Caterham Cars
Currently I don't have the funds or I would have a go at this for sure.
