I'm trying to find information regarding the angle of the fuel injector with respect to the air intake. Basically, I want to know how important it is, and how changing that angle would affect the performance of a vehicle. I'm working on a Formula SAE race car, and my team and I are looking to improve our design from last year. One of the things that wasn't looked into last year was the angle of the injector relative to the intake tube, so we want to find out if there is any importance to that. Does anyone have any input? I have two pictures of last year's fuel injector port.
