hi, im planning on fitting 750cc injectors to my rover turbo but i dont know which spray pattern would be best for a performance engine that still needs to do its job round town when off the boost & driving safely, asnu injectors offer a 10, 20 or 30 degree spray pattern, i assume 30 degree would give better atomisation but could possibly spray straight through the valve into the cylinder leaving some liquid petrol in the cylinder actually hindering combustion. would this be a correct assumption in which case a spot of measuring through the injector port and inlet ventricle in the head would tell me what spray pattern i require, or am i way off?
