I have a 1991 LX 5.0. Its a street car. Tags, insurance, inspection, all the things that make it legal... ish. 306 CID, B303 cam, 3.73's, T-5, springs, dampers, aftermarket exhaust from the block back, etc.

I will be making a few appearances at the local tracks around my area. I am going to put spray on it until I can afford to refresh/replace/S/C the engine.

I am looking real hard at a 150 shot or so. Any ya's or na's on this idea? Wet or dry? I do know the differance between the two, but is one more reliable/safer/better than the other on a 5.0? Any input is appreciated.


Thanks!! HB

you can use the 150 shot on your setup, the only difference between dry and wet is one makes more power, and thats dry,

Just curious, but how would it make more power over wet? Nitrous oxide is nitrous oxide isn't it?And thats not true about being the only difference...Dry is injected seperately from the fuel and wet is injected with the fuel. Correct?

[droppedbass87]

yeah thats what i thought??

Your wrong...

Wet adds fuel along with nitrous...

Dry just sprays nitrous...

Dry kits are easier to install...

Wet kits take alittle more work...

And its preference...

From what i have read from "TurboLX" on nitrous I dont really think he has any experience with it...

oh shitt... i thought i put down wet, no seriously my bad, i know nitrous but not as much as others

[homebrewed]

Good good... Keep comin'.
Whats the negative/positive side to either on a 5.0. I have heard that nitrous tends to "pool" in the intake. Any merit to that? If so, would a dry kit be more prone to not doing this?

I have done a few wet systems in various cars and 2 dry systems. The dry were bikes.

[SWEET2KSTANG]

puddling is primarily caused by low bottle pressure,or too big of a fuel jet. wet kit is safer, dry is safe but is more prone to harm. by that i mean, the larger the shot the more stress to the fuel system. you will have to make sure that the fuel delivery can keep up. if the car is tuned and set up correctly it will be fine.

[droppedbass87]

hey sweet2kstang i need a lil help..did you tap into your schrader valve with your nitrous kit...??well do you take off the stock schrader valve and get a fitting that goes in its place??because if you just screw your hose onto it with the stock schrader valve you wont have any fuel going to the solenoid..am i right??

[SWEET2KSTANG]

you will have to take off the schrader valve fitting and put on a fuel rail fitting in its place.

[droppedbass87]

ok i see..i will try lowes cuz i didnt get that fitting..hey do you have any pics and close up pics of yours??

[SWEET2KSTANG]

this should be the fuel rail fitting you need. http://www.jegs.com/webapp/wcs/store...-1&showValue=1

and a couple pis of my set up:

[droppedbass87]

yeah i ordered one but i ordered one and the end coming up is a male..not a female..

[droppedbass87]

and mine is a 1/16 in the fuel rail not a 1/8th..and your set up is bad ass..but where is your wot micro switch that activated your window switch??

HB .. Basically .. running too rich or too lean leads to this. Puddling is cause by basically not allowing the fuel and nitrous to atomize properly causing pooling or puddling of fuel in the intake manifold. I know alot of people .. even myself have thought that it was just spraying under a certain rpm period that cause engine detonation.. but it really depends on what gear you're in and how fast you are going .. spraying in 1st and 2nd .. you can pretty much spray at anytime you're slamming and throwing those gears .. but spraying too early in the later gears or spraying going to slow in the later gears can cause engine detonation ... that is why you want to have control over what rpm you spray at to ensure it doesn't spray at the low rpm in a higher gear ...

And by they way .. IMO ... and in the opinion of many pros, Wet is better than dry for this reason. The "dry" system uses the factory fuel injection to enrich the nitrous introduced into the engine. What sucks is that no matter how much nitrous is delivered at a certain intake port it always gets the same preset amount of fuel, and if a fuel injector becomes clogged you're f'd. The "Wet" system introduces a precise amount of fuel and nitrous through the nozzle that atomizes the fuel to microscopic proportions. This allows every cylinder to receive a precise mixture of fuel and nitrous insuring a safe and powerful set up

[droppedbass87]

well lets im going to run 3 times only at the track and all i have is the micro wot that comes with the kit and then goes to the relay to activate the system..is thqat ok for only 3 runs guys??cuz after that im ordering the rpm progressor..

Thanks for the "wetter is better" advice....
So I'm lookin' at the fuel system...
Holley 190LPH in-tank pump, Aeromotive or Holley adjs. regulator and 24lbhr injectors. Are larger injectors necessary for the 150 I have my sights set on? Also, larger rails? Yes no?

Nice set-up SWEET2KSTANG :award Looks good

[SWEET2KSTANG]

thank you. larger injectors, pressure regulator, or fuel rails arent nesseccary to upgrade on a wet nitrous set up. maybe on a dry but that will be something that you will need to talk to your tuner about. i am running a 125 shot on my car with just the mods that are listed in my garage. a fuel pump or boost a pump is recommended after 100, but is up to you wether you want one for anything less.
