I have a quick question. I have a vortech A-trim (5-6 psi)just lying around at the house, and i want to install it on my car. All i have in my car is a cam and some stock replacement headers. I have 24# injectors (not installed yet)and the matching mass air meter along with a fuel pressure regulator. Do i need an FMU in order to put on the supercharger or can i just install it and just put on the bigger injectors and raise the fuel pressure.

The FMU is required if you don't have the following:

Larger Fuel pump
Larger Injectors
Calibrated MAF to the larger injectors.

Otherwise, if you install a S/C on a stock setup you need to use the FMU. The FMU acts as a restriction in the fuel return line to bump up fuel pressures as a bandaid. Most people will tell you do to it right the first time.

So if i already have the 255 fuel pump and the 24# injectors with matching mass air, can i go ahead and install it?

Yes but.... (There is always a but) The 24# injectors might be a little small for an S/C'd car. This I'll defer to the people who have the most experience with it though.

Yes You will be ok with only 5-6lbs of boost with the 255lph and the 24# injectors.

if you dont run an fmu, you will have to have the car dyno tuned because the afpr wont be able to add more fuel when under boost. do it right and have it dyno tuned. the 24's might be a little small

I wouldn't run anything smaller than 36lb injectors without an FMU with that blower.
