Fuel pressure regulator?

[crashGTR1]

Hey everyone. I was talking to one of my fellow Stangnet members tonight and he recommended that I get a fuel pressure regulator with gauge and told me it would give me about 15 hp. Is this true? What exactly does it do? Thanks.

you can gain hp if you are losing fuel pressure, but since you are close to stock, i don't think you will gain anything.

No it's not true. Any HP gains that might be there immediately after installing the fuel pressure regulator will be the result of the engine running rich and the adaptive strategy will quickly learn to compensate and your air-fuel ratio will be back to where it was before you installed the regulator. You already have a fuel pressure regulator built into your fuel rail, and it isn't replacable. Unless you have a reason to set your fuel pressure to a specific level, don't waste your money.

Actually, If the fuel pressure system is still the return system like it on my 96, then he can replace/remove the fuel pressure regulator. It simply unbolts from the rearward part of the driver side fuel rail, and the aftermarket (I think BBK makes some) regulator replaces this as the stock one did.

They say that reducing the fuel pressure will gain some power, but that is by leaning out the car, which isn't always a good thing if you get too lean. I DO agree with SAM98 that, to compensate for the lost fuel, the car, In order to regain its wanted A/F ratio, will simply dump more fuel through the injectors, thereby negating any advantage.

I'd just save your money for your PI swap

Excellent. How are you liking your headswap? What kind a port and polish did you get? The cams you have, are those the mild grinds or the more agressive ones? How much horsepower are you putting to the wheels? Forgive all the questions, I just can't wait until I do mine. Thanks.
