WR fuel pressure regulator Options

[nk_pimpin18]

will this really add hp to an angine without a turbo? Is it worth upgrading your fuel system if you dont have a turbo? I was thinking of getting new injectors and a fuel pump, but i dont know if its worth it and how much more hp will i gain on a 7afe.

No..

I will repeat my self again.

YOU have to have somthing to control your fuel maps, cuz stock ECU wount let more fuel anyway.. and your stock pressure regulator wount let more fuel.

And if you think that you have more air now with the intake, you are wrong,you only have free flow now, the engine its self can not start breath more... you have lower restriction. I you want more air, port and polish your intake manifold / head, get bigger trottle body/ Individual trottle bodies and etc.. Get good cams, cam gears, higher compresion pistons. Then you can add FPR and adjust the fuel maps, and maybe gain about 30 hp maybe a bit more..

And you still wount need bigger injectors, cuz they wount be on 100% duty cicle anyway, you can upgrade fuel pump with the stock injectors, but still it will be money on the wind...

Cuz first of all you dont know if you need more fuel or not, you have to see whats going on in your engine, and after this, adjust it to the max.
