Ben,
If you don't even know the rules and regulations, then what chance does anyone stand helping you . Throttle bodies and the like WILL be classed as fuel injection you muppet. I would imagine they have specified that it has to be a single carb as well to keep costs down. What about fitting a radiator inside the car in the crash structure, so he retains as much power as possible, because this will obviously be dying off towards the end of the race as the car gets hotter and hotter!
