Supercharger question??????

91notchbk · May 15, 2007

I am looking at adding a supercharger to my setup and want to be around 400rwhp. I already have a 190lph pump and don't know if I need to get a 255lph? I also do not know what size injectors will work. I currently have 24lb. I know were I can get 30lb injectors for a good deal but will they be enough?

255lph at least, maybe even an inline pump to be safe. As for the injectors you can get away with 30lb'ers if you're going to be running an FMU. Many on here will tell you to forget the FMU and go bigger injectors with a custom tune.

So one option is to replace the 190 and put in a 255lph. Get 30lb injectors and an fmu. Does the fmu have to be calibrated?

the FMU is what is doing the calibrating. depending on what ratio you are running it increases fuel pressure as boost increases. if you buy a kit from soemone like procharger it will come with every thing you need anyways. but if you are peacing together a kit you are gonna need to get one. or bigger injectors an adjustable pressure regulator and a custom tune. which i would advise anyways.

Ok. So what fmu do I purchase along with what injectors?. Votech has a 6:1 FMU that they say can be used on Mustangs using either 30, 36 or 38 lbs. per-hour injectors. So would this fmu, 30lb injectors, and a 255lph work for my application?
