Why oh why do the Cossie mob (don't take that the wrong way folks...) talk in 'blues' and 'greens'

Why not just 450cc and 550cc like eveyone else, makes it so much easier to make the things!

Anyway, the question I need answered if you can help please, is what is the flow rate for the Cossie 'blue' injectors - the standard ones fitted to the Sapphire 4x4 (allegedly) - dark blue Bosch ones. Actually, someone seemed to think they were Marellis...

Thanks.
