Can fuel pressure be raised (permanently) on our returnless system? All u would have to do is change/modify the intank regulator, right?
What would be a safe increase?
Using the equations from RC Engineering's site, a 240cc injector could flow 310cc's if fuel pressure was raised form 45psi to ~75psi, but it's probably not a good idea to run that kind of pressure all the time. Would it kill the injectors?

Rep Power: 281 fuel pressure can only be raised when there is an adjustable fuel pressure regulator in the fuel system. Unfortunetly there is no adjustable fuel pressure regulator available that works on a returnless setup. This is the reason why so many have switched to a return style fuel system.
75 psi seems really high to be running all the time. my fuel system is based at 43 psi but adds 1 psi of fuel for every psi of boost. (boost referencing fpr) so at most i should see 51 psi of fuel while under 8 lbs of boost.
why not go with some RSX-S injectors which are 310cc. These are popular for boosted d17s including mine.

I was just looking at the install/remove diagrams from the Helms manual and thought this might be a cheap mod.

Rep Power: 281 yeah i know that all too well. i've been in and out that tank more than i can count on my hands.. the only thing you can do there is upgrade the fuel pump.. theres really no room for anything else, especially adding more stuff.
