Bigger injectors hp gain?
Is it worth the extra money to put in bigger injectors like 750cc on a vf39 2006 wrx. What would be the gain as opposed to the 565cc stock injectors?
Current mods include, vf39, sti tmic, perrin turbo inlet, cobb downpipe, cobb intake with box, cobb ap, cobb pulley, grimmspeed 3 port ebcs, grimmspeed up pipe with Tial 38mm ewg setup, walbro 255, and oem sti catback. Trying to get the most hp with the stock sti catback. Was going to put in 750cc injectors while I have it all taken apart, but if gains are minimal I will just skip straight to a protune!
Zero, unless you're already maxing out your current injectors...
My Idc is at 85% max on my data log. Just seeing if having bigger will help out tuner to adjust the flow and get me better numbers.
