Will someone explain to me how I will regulate the fuel pressure when I go to return style fuel system to 1 jack it up as high as I need it and 2 have it stay where it needs to be at different rpm ranges..im just wanting an explanation on how this works before I get into further questions..

I believe a 1:1 FPR is what you may need, however I am not 100% on that. I am trying to find a decent write up on boost related fpr's to better illustrate this for you.

Basically a 1:1 raises fuel pressure 1 pound for every pound of boost it sees.

*EDIT* Did your engine not have a FPR on the rail already? The factory one for the supercoupe should be sufficient...

What if I wanted to use an aftermarket regulator? How does that work? anyone have pics of one installed on a return style system?

And really w a 90mm maf, the biggest TB I end up finding hopefully 75mm+ not sure what to go with yet...and 60lb injectors that factory SC regulator will keep up?

BBK Mustang Billet Adjustable Fuel Pressure Regulator (94-97 GT; 94-98 Cobra, V6) 1707 - Free Shipping!

Install an adjustable one and you can set it to the psi you would like. Really I wouldnt think you would need anything but the stocker. It sets the pressure at 36psi? 42psi? (whatever SC stock is). Even with all of that you probably wont have an issue until you start pushing alot of boost. Somebody more experienced in this needs to chime in

It should in theory, because all it is doing is regulating pressure, not how much fuel is makin it to the cylinders. If you are going to turn up the boost, then you will probably need to pursue a RRFPR.

I wish I could find one article in particular about pressure regulation, but I can't for the life of me right now for some unknown reason :computer:
