i tried a search but didnt find the answer i needed.......can we hook up nitrous to the port that is on our fuel rail......and will it reach all injectors that way......if you have tried this let me know......

joeworkstoohard

i don't think that you'd want to do this. all you'd do is increase the pressure inside of the rail,which i think would actually cut back on the fuel and lean you out. if i understand what you're asking

silverSS

why do you wanna run nitrous? how many psi is the fuel rail on the ls?

IonNinja

are you talking about the test port? if so yes you just remove the schrader valve and you're good to go...

this is how several people run their fuel line to my knowledge...

joeworkstoohard

i was thinking that he wanted to inject the nitrous INTO the fuel rail

redlineblueline

That seems to be what he is doing.

slowion2

that'd be the wrong way to do it too

unless he's confused and meant those NOSzle systems that the injectors sit in, which I do not think will fit/clear everything

Skottish

im talking about the test port that ive seen the systems hooked up to on here......i am wondering if there have been any problems with that and if the no2 reaches all cylindars

slowion2

the test port is tapped to get fuel to the fuel solenoid, nitous is NOT pumped into the fuel line and in turn the injector rail.

you need a point of entry for the nitrous/fuel mixture, whether it be a single fogger (most likely what you'll need to go with) or direct port (one fogger per cylinder; as close to the port as possible most times).

if you were concerned with cylinder distribution through the 2.2 manifold it's fine, probably more even than most I"ve dealt with.

you get what I'm saying?

MVP

you can do it infact with the nitrous express in thier instructions that where they suggest tapping for fuel if you have a wet kit.

Skottish

so the test port is merely for the fuel solenoid......ok......im completely new to no2....this gives me a little more understanding.....now with the single fogger, where would i install that?.....the intake?......thats what it looks like in this pic: http://i72.photobucket.com/albums/i1...Picture006.jpg .......im just trying to get an understanding of this

IonNinja

yes the nozzle is inserted into the intake and the fuel and nitrous lines are run into that nozzle

I believe the nozzle is supposed to be about 6 in. (can't remember) away from the throttle body to allow for a cleaner mixture of the fuel and nitrous.

Skottish

ok......it seemed to me that the fogger would cause fuel to spray all over the inside of the intake.....is that a problem or does the airflow prevent that?

HackAbuse

So what exactly did you guys have to do to tap into the test port on the fuel rail?

Skottish

remove the schrader valve.....its the same thing that is in a tire valve.......

HackAbuse

I know that much, so what do i do, just tear it off? lol

wont that be leaking gasoline like a bitch until i get the fuel tap in?

Will the nitrous fuel tap thread right onto the old valve?

MOD MONEY

Im runnin nitro wet shot 75 via fuel through fuel rail, no problemo.

MOD MONEY

also I got the shot after the s/c drilled into the block.

slowion2

the airflow, nozzle design (that's why it's called a fogger), and the pressure at which the nitrous comes out of the same nozzle will all prevent the fuel puddling issue that you're thinking of. if you just sprayed fuel, it would only be coming out at 50-60psi, which would be a small stream type deal, as opposed to fogging out and being distributed properly.

you know if you want, I should be in Port Richey this saturday for a little while, I'd be more than happy to show you my setup and how it all works.

lol if you managed to tear the whole port off yeah I'd imagine.

dont' take the cap and valve out until you're ready for the fuel side, but yeah you use the same tool as for a tire valve, and the braided steel line will thread right on to the same thing. you want it tight but don't overtighten it, bad things will follow. if you really really wanted to, just seal the fuel fitting to the solenoid, mount the solenoid, and run the line from the test port to the solenoid. they are closed by default so it won't leak.

Skottish

slowion, i wish i had real this sooner.....i havent had the time to check this sonce my last post so i just read that you were in town.....any idea on your next trip here?.....id like to see the setup.....

slowion2

ah that sucks man.

I'm not planning a trip any time soon that I know of, but if any come up I'll let you know

here is some nice stuff i found today

that's still the same as the N.O.S. GM EFI Wet kit (literally, it's the same kit with a different label) but has almost 200 bucks tacked on. you're going to still need to do the same thing for both kits. I only recommend the NX GM EFI Wet kit that I run because it has given me 0 problems since installing it, is a good buy, and a trusted brand. your install is going to be the same for any nitrous kits like that.
