I am wanting to put a Nitrous kit on my car. For the time being I want to play it real safe and would like to shot a 50 shot. I have heard many great things about the NX wet kit (do they make and Dry kit Now) but Then again I have HEARD BAD stuff as well with Wet kits. We have had the NOS 5177 Dry kit on both or our LS1 cars before. Does the LT1 like this kit, does it like Dry systems. I am wanting to build a Forged 355 until then I don't really want to shot over 50 maybe 75 AT MOST FOR THE TIME BEING. I know with only a 50 shot or 75 shot I don't really think I will need biger injector and I beleive my stock fuel pump will work (AM I WRONG OR RIGHT) I will be getting a Duel purge line for my WS6 so I can purge the Excess nitrous through the hood. I want a window switch also so I can save my Tranny. I need all the help I can get. ONce the motor is down in about a year I will up it to a 150 but for know I would like to stay at around 50.
Any help would be great fellows

 

I am not an impartial judge becasue I am a Warehouse Distributor for NX, but I prefer the wet kits. NX doesn't make any dry systems at all and I doubt they ever will because they don't like them due to safety issues. A window switch is a great safety device for nitrous systems but not really what you want to save your tranny if you talking about not running the nitrous during gear changes. A WOT micro switch or a TPS switch would work better for that. The window switch keeps the nitrous from engaging at too low of RPMs and shuts the nitrous off before you hit the rev limiter which is very good thing, but if you want to disengage the nitrous during gear changes the micro switch or TPS woud be a better choice. How they work is that as soon as you let off the throttle any the nitrous shuts off. The window switch would require the RPMs to drop below the lower chip limit which is usually 3000 RPMS before the nitrous would shut off. Every NX kit comes with a micro switch as part of the kit or you can get the TPS switch as an option. The TPS switch doesn't do anything that the micro cant do it just simplifies the installation and makes for a cleaner appearance under the hood. I run both a mciro switch and a window switch on my car and the way I explain it to most people is that if I do my job as a driver the window doesn't have to do anything, but if I get carried away(which is easy to do in the heat of battle!!) the window switch will save me. If your car is in good mechanical condition I think you could easily run a 100 shot on your stock engine and there are many here on the board that run 150 or 175 on stock motors. I saw in someone's sig the other day that they were running very low 11's on a stock longblock using nitrous! Pretty amazing! If you are interested in a NX wet system let me know and I will make you a great deal on a new system. Thanks

 

I converted to NX a while back from NOS and compucar... and never looked back.

I think T/A kid is probably running and A4 if he was concerned about tranny life, and wanted to use a window switch to cut the nitrous off before he reached his shift point.

 

Yep I am a A4 with 3:73's and 3000 stall. I am leaning toward the NX kit. But aren't wet kits more dangerous than Dry kits our am I wrong. I have heard this
LS1= Dry
LT1= Wet

 

Get a wet kit...you won't regret it. Dry kits rely too much on the injectors and if only 1 failed you'd be building a new engine. Believe me I know from experience. I will always run a wet kit from now on. Besides wet kits are much easier to tune that dry kits. JMO.

Well then the NX Wet kit is the one I want to get then. The injector thing scares me about the DRY kit. I DON"T have enough money income to build me another engine if mine messed up bad. Besides a 50 shot wont hurt anything. IF stock LT1's can handle 100 shots then my should handle a 50 very well.
I am planning on using the XE 224/236 nitrous/blower cam on a 114 LSA and spray maybe a couple of times a MONTH (unless I get addicted).
I hope this cam will work fine since I will be NA most of the time but I will spray every now and then.
Thanks alot guys any more advice would be great. what are yall's ideas on this cam with a 50 shot

 

You'd probably make more power with an N/A specific cam on a 110 or 112 LSA. I wouldnt worry about a nitrous specific cam until you went well above a 100 shot.

 

Not to argue, but just to throw in my 12 years of experience.
I have sprayed dry kits way before NOS invented thier patented kit. Fuel injection is a beautiful thing accompanied by a dry shot.
I was actually spraying a dry kit back on an LT1 TA in 93 when it first came out. I went through hundreds of bottles on several cars and never had as much as a burp. I also got brave and sprayed 150 shots on a stock fuel system....no problems.
People have had success with wet and dry kits. Also Ive heard horror stories with both kits. I guess is all up to you to pick your own poison and live with the results.
I never liked spraying fuel into an intake that was made for air only.
JMHO

i would suggest wet kits. there have been rumors of wet systems "puddling" fuel in the intake,but that isnt exactly a common thing.

i have been using nitrous for over 10 years,never considered a dry kit unless i had DFI/FAST/Motec etc fuel injection.

For your application i feel a wet kit would be best,and yes a 50 CAN hurt the engine,but unlikely.


im the guy speedtech was referring to about going low 11's with a 100% stock longblock and nitrous.

 

ON wet kits does puddling in the intake only happen at big shots(150+). OR is there a chance of puddling in the intake with little shots as well. I have heard that the LT1 intake is ONLY desinged for air. Yet so many people are succesful with wet kits for the LT1. I Hope I will not be one of those unlucky ones.
Isn't there a Vaccum system in the intake to stop from liquid from puddling or is that bogus.
