Nitrous question, Is there such a fuel pressure regulator?
I'm going to isntall a dry nitrous kit in the near future. I want to raise the fuel pressure when I'm on the bottle, but I don't want the pressure when I"m off to save fuel. Is there such a regulator that will raise the pressure when I'm on the bottle and off when I'm not? Thanks

um, no they dont
dry kits induce nitrous only, but the fuel pressure will stay the same wether you are on the bottle or off.
Thats why they have wet kits, b/c there is a certain point at which a dry kit will cause a too lean condition b/c you run out of fuel.
If they had dry kits that raised the fuel pressure when you are spraying there would be no need for a wet kit.

convert the dry to wet, run a high flowing fuel pump, set the FPR at one proper setting and you're set really.

nope, dry kits increase fuel pressure via the FPR.

Re: Nitrous question, Is there such a fuel pressure regulator? (rewsnaeht)
no, YOU can adjust the fuel pressure via the adjustable FPR, they dry kit won't do it for you.
Think about what a nitrous system does, it sprays n2o into the intake and into the combustion chamber, that is why you LEAN out if you go too high (50 shot or so).
If what you are saying was true then there would never be a need for a wet kit b/c all you would have to do is let the system up the fuel pressure.
do the homework man

Re: Nitrous question, Is there such a fuel pressure regulator? (foozball-26)
and once you are at wide open throttle, the fuel pressure cant get any higher. the only way to run a dry system is to increase through the injector. via raising the base fuel pressure or replacing the injectors to a bigger size. a wet system adds the fuel in the foger nozzle. way more cost effective. nitrous cars arent like turbo cars. if you use a boost dependent fp regulator, you need boost to activate it. so the only way to get the added fuel on a dry system is to go big on th einjector or raise the hell out of your base fuel pressure.

You obviously have not done your homework. Your statement is completely false. You are correct that dry setups only inject nitrous into the intact tract, but the fuel needed for the nitrous is supplied via raised fuel pressure through your fuel injectors. Dry setups use two nitrous solenoids with a nittrous pressure regulator teed between them. You run a vacuum line from the nitrous pressure regulator to your fuel pressure regulator. When the nitrous solenoids are activated a signal is sent from the NPR to your FPR and your fuel pressure is raised to 70+psi to accomodate the nitrous being injected. What do you think you can just add 50-75hp worth of nitrous and not add any fuel? Read the instruction manual for a dry nitrous kit and then you'll understand what I'm talking about. The reason why a dry kit has it's limitations at 70-75hp on a 4 cylinder engine is because the injectors are maxed out fuel pressure wise and can no longer supply enough fuel for the nitrous being injected.
The reason there are wet kits, are for poeple who do not want to put their injectors under any extra stress. Wet kits max out at approximately 75hp on a 4 cylinder engine as well due to possible distribution problems between cylinders. This is all simple newbie stuff, you should have a done a search.

this is correct.the purpose of adding nitrous to your engine is to create a way to burn more fuel.if you add just nitrous and no more fuel, it will probably blow up.the dry kit uses the bottle pressure to increase fuel pressure so you are adding nitrous and fuel at the same time with the correct mixture.if the bottle pressure is high,it will add more fuel pressure.if the bottle is low,it will add less pressure to make the mixture correct.

Re: Nitrous question, Is there such a fuel pressure regulator? (turbotypeR)
yes there are dry kits with the NPR, there are also kits that are only for small shots and do not use the extra solenoid. Its a matter of which kit you get or build if you do custom work.
What some people do instead of adding the NPR is up the fuel pressure via a FPR and just run rich while not on bottle, its the wrong way to do things but whatever floats their boat.
to answer his original ? about whether there is a FPR that does this, it comes with some kits, and some don't make sure you get one with it.

Re: Nitrous question, Is there such a fuel pressure regulator? (foozball-26)
NOS and ZEX both use a NPR to raise your fuel pressure via your FPR and NX doesn't sell dry kits so, unless you piece together an incomplete dry kit your fuel pressure will be automatically raised when your nitrous is activated.

the ONLY kit i have ever seen that does not use fuel enrichment is the nos brand "sneaky pete" and i think they only go as high as 30hp shot.

^ This guy is right. That other guy is completely wrong. Adding ~50hp without adding more fuel ?! hahahaha, the funny thing is that he thinks he's right too. He's obviously never installed a DRY setup before ...

Re: Nitrous question, Is there such a fuel pressure regulator? (dmotoguy)
guess the engineers at NOS are morons then, since they had a kit w/o the 2nd solenoid for raising the fuel pressure.
It was however like 6 months to a year ago I saw these kits, Havent looked at since then b/c turbo owns nitrous.
