Gareth, i agree 101% on massive power N/A motors, but do you really reckon that its an advantage on a turbo motor where the charge is so hot anyway?
Its not something ive got any data to support one way or the other, but it seems like its going to be less useful on a turbo, especially when you are fully on boost and not managing to burn all the fuel anyway because you are running so rich to use the fuel as a det surpressant?
(or am i missing the point and it allows it to work BETTER as a det surpressant for the same reason?)
