sound like a major PITA to run a 2 stage injector system based on throttle position. i guess a race engine doesnt really suffer from problems at idle or low throttle angles
i think i might stick with the stock location for the injectors in the head. ill see if i can set up the foggers before the butterfly for all other WOT 'fuelling'
that way i still atleast get some cooling and atomisation benefit for the larger output numbers
