I am about to install a powerdyne supercharger with a 9# pulley, 70mm throttle body, 255 l/hour fuel pump, and an Edelbrock Performer RPM II intake. Do I need larger injectors than the stock ones I currently have? I live in Utah at an elevation of about 4000 feet which I believe helps a lot and I was also told the stock injectors are rated at about 40% less than what they can actually put out. Does anyone run a similar setup that can help me out?

nobody hear will run a similar setup cause nobody hear will ever buy powerdyne.
i suggest you dont either unless you already have.
they have a habit of blowing to pieces and sendint those pieces into ur motor.
and that then blows the motor as well.
but anyways u would need new injectors as to what size im not exactly sure
there are some guys with semistock motors and vortechs and i believe they're running 30lb injectors

Well it depends on how you want to do your fuel system. If you bought a charger package, I'm sure it came with an FMU. If it came with an fmu, then the 19's should be fine. They are designed to make small injectors spray like big ones. The correct way to do it, would to be upgrade your mass air and injectors, because the mass air has to be calibrated for the injectors. Then have it tuned. That way you are efficient and safe.

As far as powerdyne, i've heard nothing but bad things. However, i'm sure if you don't try to work them to death and push more boost than they are recommended at, you should be fine. Good luck and hopefully yours doesn't end up like my 94.
