I just bought this 94 cobra with a ProCharger p600b, putting out 6psi, what injector size should I be using? Its still got the stock 24#'S in.
I wanna ditch the stock MAF, it has issues, and thought I'd look at the injectors so I get the right set up. Any recommendations on a MAF also?

Is it currently using an FMU? Do you have plans to boost more? Is it tuned? Fuel pressure regulator?

Stock 94 Cobra puts down 245 flywheel horse power. Add approximately 40 percent more air, so you'll increase your flywheel horse power to ~340 flywheel horse power. Assume losses at 15% through the drivetrain and you are at ~290rwhp.

You are at the limit of the stock fuel system. You could get by with doing nothing, but since I get to spend your money, I would go for for 30 pound injectors, a new fuel pump (255 in tank), and while the stocker is probably enough for you, since you say its broken, a new MAF. I've never used an Abaco MAF but I like the idea of a digital unit.

I would agree with above post. I had 6 psi on mine initially and out down 292. I also had 30 lbers and a 255 lph in tank fuel pump. Answer my first post though so we know a little more

Lightning MAF and 42lbs injectors , DONE , leaves room to grow if you change things later as well

agreed with prior post, 42's and calibrated meter. ditch the fmu or sell it. you will still need a tune since it will be running mighty rich, better than too lean and boom

if you plan on growth in the future get 42s. if you plan to leave the car with just the blower go with 30s. If you run an FMU, the stock 24s would probably do the job.

If it was me. lightning MAF and 42s.

at the very very least you need to get a bigger fuel pump. get a 255 and forget about it. the last thing you want is to run out of fuel.
