Interesting thread. I know additional power can be made cooling inlet air. I have read about Morris spraying at the inlet. I can't afford to experiment with my blower. I would add piping to direct the inlet air from a cooler space and leave it. I ran a meth kit from AlkyControl spraying into the carb hat on my D1. This is a widely used system and very safe when used properly. I have since stepped up to an F2 and will be using an air to water intercooler.
