This may be a silly question, but do any of you have any experience of the in-cylinder cleaning effects of water injection? Several people have mentioned that WI cleans the combustion chamber up nicely but I don't know anyone with first hand experience of it.

I've got a low pressure supercharger on a Rover V8, which hasn't been set up yet. It may be some time before it is set up properly because there's a slight distribution problem at the moment. In the mean time I'm running it massively overfuelled to make sure none of the cylinders lean out. I expect that in time this'll coke up the insides of the engine nicely and could aggravate detonation problems. So I was wondering whether my WI system is going to be any help to control the coke build up?
