ive searched and i couldnt find it. is it possible to adjust the fuel pressure to make horsepower in the high rpm range? this is a general question on any motor

 

Not if the engine is already properly tuned, adding or subtracting fuel may lead to a decrease in performance.

 

If your just dumping fuel in wouldnt it cause it to run rich??

 

Your signature tells the whole story. Nothings free.

 

so if i added a aftermarket fuel rail i wouldnt gain anything instead i would run shity rite?i was thinking that maybe at higher rpms the motor needs more fuel so a little extra work on a better fuel system on an all motor platform would add power

Correct. Nothing would change.

No, it would run the same. Adding an aftermarket rail doesn't change anything.

1. The first step in getting more fuel to the motor is to upgrade your injectors. Leave the other fuel components alone.

2. Modifying/changing/upgrading the fuel system doesn't add power. It doesn't do anything other than allow you to to flow more fuel, if need be. A car is like a computer - there's hardware and software. You can't just throw on a bunch of new hardware and expext it do anything when you haven't installed the corresponding software. Well, it's the same for your car. You can modify whatever you want, but you need the appropriate tuning software to make it work.
