5.0 Injector Question

[dls322]

I was looking to upgrade the stock injectors in my 5.0. I'm currently running a stock fuel setup with speed density. What would I have to do to upgrade to higher pound injectors? Would i notice any change in the performance of the car? Thanks for all your help!

You do not need new injectors. They just add more fuel - they don't give you extra power but just fuel to support the extra air flow (you will need more mods for that). I would just clean out your stock injectors (fuel injector cleaner) and be done with it

I would not upgrade your injectors to a higher PSI yet. It will not give you any performance. By the time you are ready to upgrade to bigger injectors due to too much power then you will most likely need to convert to mass air as well.

Thanks for the info and fast response!

Ditto to what they said, prepare to convert to mass air unless you dont plan to mod, or dont mind dealing with tuning headaches

SO not true.............

Cam selection is the only thing you have to be careful about with speed density, and there are some excellent cams for SD out there.

Yea after i wrote that i knew someone would correct it. But, at least i can be the devils advocate.

fully agree...my 331 sd project is almost complete!!!

I'd really like to keep tabs on this project. Are you using a tuning software (EEC-tuner or TwEECer) or are you letting the EEC tune a well matched combo?
