Nitrous, DRY OR WET???
Ok, now I'm reading threads that are telling me differently, so Im getting worried. Im about 80% ready (I have 80% of the parts) to install a NOS kit into my car, and am now trying to see if I should continue with my WET kit install, or fall back and do the simpler dry install. Im probly gonna be doing no more than a 65 shot (45-50 for everyday driving).
I REALLY dont want to run my car lean and fry the engine, as if I do, I am SCREWED, but I also dont want to run it rich and fry the cats. Which kit should I do... Dry or Wet. Please post your opinions, and no "you should get a zex kit" please.

NOS is THE system to use. I wouldn't trust any of those dry systems....

Wet systems do not work very well with our long intake runners.
I think I would be partial to Nitrous Express stuff ;-) |

ddman, i am having the same problem also!
i am pretty good with wet systems and know more about them than dry sytems. i just installed a wet sys(nitrous express) into my friends SVT contour last week(its not running yet, due to a fitting for the valve stem for the fuel line). but this is what i understand: wet systems bypass the injectors and inject the fuel and n2o together. which is good. dont rely on injectors. dry systems rely on injectors to supply enough fuel, by vaccum and increase fuel pressure.(correct me if i'm wrong) which cant be good since our injectors max out @ about 200 hp. so if you have any other mods (i.e....exhaust, intake) your screwed. unless you run a 35 shot. also lets say you shift too late and your ecu cuts fuel. kabooommm. but then a msd window switch can take care of that. then again that zex sys seems pretty easy and i have only heard good things. i like the fact there's not a lot of crap (i.e. soleniods, WOT switch) in the engine bay. good sleeper kit. please correct me if i am wrong, i do say a lot of stupid crap. hahaha texasrs & ddman, i thought NOS systems were dry?????

thanks julian, thats true.
but i should have made myself a little more clear. yes the injectors can go to about 220 hp. but that is EXTREMELY dangerous. i meant they will go to about 200 hp staying in the 80% duty cycle. pass that 80% you could create them to lock up which means you can say good bye to your engine. right???? any trubo people barely get away with stock injectors, and some dont get away with them at all. i know imprezinator runs NX, here are the pics on his RS. click here correct me if i am wrong? |

Ya, iv been talking to him on how he did it and all
mybe this is what ill do. Do a combo of the wet/dry. They recomend a 37 jet nitrous and 22 jet fuel for a 50 shot. That keeps it stoichometrically correct (but just for the amount of nitrous and fuel). Well, dry kits dont add anything, so what ill do is montior the plugs, and change my fuel jets. If a car can run w/o ANY added fuel, then i could easily run the smallest fuel jet avaliable to just help out the injectors and make SURE I dont run lean. |

venom's are wet kits....wet is the way to go to stay safe w/o modifying the factory FPR....eric(imprezinator) runs a wet kit...best guy to talk to but he's been busying rebuilding his car.

Venom is NOT a wet kit, its not exactly a dry kit either. it works buy adding unjector pulses after the stock ECU has added fuel, by doing this you dont have to mess with timing when you move to a 55 shot or bigger. it doesnt work on any vacum like a dry kit but it also doesnt inject the fuel with the nitrous like a wet kit, i think this is hands down the safest kit on the market and its $1250 price tag is worth every penny if it saves your motor. im going to be finding out very soon

qoute:
Venom's VCN-2000 Computerized Nitrous System The worlds most advanced nitrous system to date. Featuring closed loop fuel operation utilizing two dual processors to control nitrous module. Special safety features insure proper air/fuel mixture or the injection of nitrous is shutdown before catastrophic engine failure. Kit comes complete with all necessary hardware and installation instructions. VCN-2000 utilizes stock injectors for fuel enrichment during nitrous injection and is available for all late model vehicles that come equipped without a fuel return line. "Like something strait out of the Movies!!" this is from the link from racer25 venom is a dry setup. what i understand is that it monitors air/fuel by using the stock o2 sensors. which is not a good, our o2 sensors are crap. or at least i wouldn't my nitrous being monitored by o2 sensors, maybe if they were some sort of "racing" or much higher quality than stock. |

thats the best price ive seen yet. they have a bunch of different part numbers for the VCN-2000 kit (just because the software for every car is different) if you call venom they will tell you exactly what part number is for your car,they're really nice and will answer any and all questions you could possibly have. i was one the phone with them for over an hour!

As for some of the other posts, please try and read about nitrous at the 'HowStuffWorks' site. It's really informative on the difference between the wet and dry kits. I'd say use a kit that's made for your car (Zex for example). Otherwise, if you are in doubt, your best course of action is not to use nitrous at all. Even with the right kit, you still take a chance with the product. You could get a bad install or even a malfunctioning part (or bad part) of a good kit go wrong. Shi* happens! Good luck! |

dman, i have been running a dry NOSkit on my 01 rs for the last six months. I have had no problems with it........... I changed for the wet kit to the dry! My last car i had a wet kit and i had to many intake manifold back fires....... One even blew fire out my intake and burned my filter! from gas puddling in the in take..... If your going to run less than a 100 shot the dry will be fine. i'm running an 80 shot with at 900psi and the car rips.... with the new nos kits you run all the factary fuel,plugs ect. vary smooth!
make sure you buy the fuel presser sender! if some thing go's wrong with fuel presser it will not fire the second selonod. your car from the factory run's rich, i have a jc sports chip with makes the car run even richer and i have no problems. |

Well, I have NO FUEL MODS, and dont intend to do any (no RRFPR) or anything like that. I also intend to do most of the bolt-ons including full exhaust and headers, and intake.
I will be using the STOCK INJECTORS and FUEL PRESSURE all the way. Is this safe enough for a 50 shot. I REALLY dont want to destroy this engine, and dont have 2500 to spend on a trubo. Im also getting the ENTIRE KIT (including 2-10lb bottles) for 275 Dry or 350 Wet, which is why im doing this. |

Hello all, as my son may have told you....I prefer it wet before anyone sticks their dipstick in.
I'm also sure you all are wondering what Nathanial looks like too. Well, here you go. <img src=http://a440.g.akamaitech.net/7/440/25/dbfba4ecaee931/www.batmantas.com/img/batman.gif> Take care. Nate's Mom |

i'm lost
okay i new to this n20 set-up but on a dry kit u tap a hole into the intake and have the nozzle right there it mixes with the air and then goes into the intake, then on a wet do u tap it into the fuel line like right after the fuel filter or do u tap it into the throttle body.
to me shouldn't it mix with the fuel in the line or am i completly wrong on this thinking (talking about wet) because if u tap into the throttle body isn't just mixing with the air because it right off the intake ~JEff PS on the nos kits r they push button for when u want n20 or r they like the zex it only works at wot with a sensor.

ZEX KIT...
...I am not voting for or against any of these company's...but...I have had my ZEX 55hp kit for over a year and have had no problems...prior to installation I installed a fuel pressure gauge and AF ratio gauge...at my local speed shop my NOS/DRAG/TURBO freaks told me to stay with a safe shot (55hp)...unless I do some internal mods to prep my engine for a higher shot! Another thing they advised me was do not stay on the nitrous/WOT for too long! So with their advise embedded in my mind and a 55hp shot... the ZEX kit works nice...nothing like Fast & the Furious where it snaps your neck back, but it does make you car feel lighter...the bottle heater and remote valve opener will be my next future installment! When I engage in WOT I noticed that the A/F ratio meter stayed in the GREEN/RICH side and the fuel pressure meter was displaying 38-39 psi! I personally can say that the ZEX kit is safe,IF you use a safe shot and don't use it for too long! The other dry or wet kits I don't know!
That's my .02 cents, CRAZY KEN |

ya, a 55 shot is 55 HP
I think im just gonna get my damn A/F gauge (and another 02 sensor) and tune it that way if I run lean with a dry kit, ill put in the wet, and start with the lowest fuel jets possible and work up until all is good. If not, then ill leave it. BTW, im assuming when you put in the wet kit, the compuer senses the extra fuel (using the 02 sensor) and backs off on the fuel delivery by the injectors. Im assuming it works the opposite with a dry (it senses a lean condition and adds fuel). am I mistaken???? |

Direct injection means there is a fogger (puts nitrous into engine) on EACH intake runner.
A fogger is ONE injection point normally before the Throttle Body |
