Chris, I know you're a good kid since i've met you face to face, but I will say the way you come across in your posts is completely different. If I may offer a suggestion, (don't take this the wrong way). Grow some skin! Someone makes a BS comment, don't respond, just adding fuel to the fire and it's not needed, besides it makes you look like a fool at times.

If anything seems to fit this board.. less is more...
good luck with your nitrous kit and save the racing for the track..

I agree, but I cant say much I talk shit back at them.

btw when are you gunna do the shot?

I think that the fpr controls how much fuel is delivered into the rail awaiting the injectors.So I see it as you having a huge fuel pump pushing more fuel then you need and running to the fpr.The fpr slows the fuel because you have to much and therefore lessens the amount in the rail so it runs at a normal pace.

.

i think this is where your getting confused........ the FRP sits on the outgoing side of the fuel flow (the fuel enters one rail, swoops around to the other then hits the FRP befroe going to the tank) so when you add more pressure to the FPR it closed down and makes the extra fuel shoot out of the injectors (it doesn't block the fuel from coming in, it keeps it from going back out into the tank) and the only place for it to go from there is through the injectors............

dry kits have a line that hooks up to the vaccum line going to the FPR (the vaccum line controlls the amount of pressure, the more pressure pushed on it, the less can escape into the return line) the line has nitrous running through it jetted at a certain level, which puts out a certain amount of pressure, which controlls the PSI of the FRP ..... more pressure more fuel, when the nitrous is off there is no pressure across this line (except for the factory line) so your FRP setting goes back to the stock setting (or if you have an adjustable one it will go back to where you had it adjusted to............

hope that helps some.......................
