i have an 04 wrx and am trying to see if anyone knows what the injector duty cycle maxs out at with stock injector on stock boost. also does any one know what the formual would be for calculating injector size of cfm...just to maintain the 14.7:1 i can figure the forumal from there.

 

thanks in advance

In whatever injector you use or size, you should really not exceed 80% duty cylce.
