joe,
even if all the injectors on a tbi spray at the same time, would it matter if it was just on top of the throttle bosy or in the ports? i mean, it does make sense as to why it wouldnt but thats how a tbi unit or even a carb works anyway, basically by supplying constant fuel based on engine load, right? so why would it matter if the injectors were above the throttle body or in the ports? i mean i realize that if fuel is sprayed into the valve pocket while the valve is closed its useless but the valve opens and closes so fast wouldnt the effect of fuel collecting in the pocket be pretty limited?
