Awsome advice thanks Tash! I'll give Bill a little nudge then to see what he can come up with! Note to nev... i went out in my mates 206 who has a Green cotton system fitted and im impresses! Gives a lovey note id be well happy with, but his is fed to the front of the engine and its sat inside a 'scoop' to catch more air flow which im sure would help a lot.
