i just picked up a new powerdyne 9lb kit off ebay for a steal. not my first choice of superchargers but for the price i'll take it. just trying to figure out the best choice of injectors for the car, 42lb with 80mm maf, or i also have 30lb with a 75mm maf. im sure either will work just not sure if the 30's will starve at the top? or are the 42's better and more receptive to tuning. thanks

The 42s will do the trick, with your combo 30s will fall short on fuel delivery, dont forget to add a fuel pump, should be a 255lph unit. A FPR will aid in the tunning, but also consider a custom made chip or EEC programmer such as EECTuner or Tweecer.

thanks for the reply, do i need an fmu with the 42's and an 80mm maf? i have seen it with and with out and have heard you can do it either way. my guess is the fmu makes it easier to tune?

I'd go with the 42s and the 80.

I have the 42's with the 90mm lightning MAF. I just got my powerdyne back from being repaired. I had the 9lb. pulley put on while it was there. Im making 11lbs of boost now.
