which is the biggest injector i can use in the evo using safc?

 

General rule is your HP should be 80% of your injector's capacity, so 480 HP would use 600cc ... If you are referring to SAFC as in the Apexi unit. I don't think that is a good tuning device. It's more like a toy. If you are getting up to the big cc squirters, it's better to get a tunable ECU or one that has the same preset specs as your mods. Don't see a fuel regulator in ur mods list, may need one of those as well.

 

but which is the size of the stock injector on the evo 7?

 

560cc
