limitations of stock FPR?
When should the stock FPR be upgraded to a higher level FPR (rather than a RRFPR).
I understand a lot of people use RRFPRS (searched) , but I think I can meet my fuel requirements using 1200ccs in the secondary slots and a constant pressure difference of 43.5psi(planning to upgrade the pump also). According to the calculator on Max Cooper's site (Terrific resource, thanks Max) this is enough for 387 at the wheels with injectors at 85%.
When does the stock FPR become a limiting factor? Second, what exactly does it limit?

You can't adjust it to run higher fuel pressures than stock. I really don't know of any other limiting factors. Do a search under "fpr" and "maxcooper", he had some good responses to a post I had about this.
