Quick n2o Q

I am looking into buying a used nx wet kit, what should Ido to get my car ready for n2o and what is the biggest shot I can run safely.

[Dr_Kyle]

Get NGK TR6 plugs, a new fuel filter, and a better exhaust. 75 shot is about the max you should run without any addt'l work although I never pushed mine past 50. Mine was a dry kit though.

[Kodeblue]

Is there a special fuel filter need or just a new one?

[SPAZ]

Just get yourself a new fuel filter, hit it at wide open throttle, and enjoy!!! If you are buying a new or old kit make sure that you either have or buy metal Nitrous Brakets for your bottle , if it doesn't already have them. I was almost not allowed to use my Nitrous, because my bottle was held down with the stock plastic clamps that came with the new kit.

Yeah i gutted my cat and I have a dry kit running roughly the equivelant to a 60 shot. I also should have my cat back friday so it is all coming together. I prefer dry because there is less of a set up and I feel less of a strain on the overall fuel system and car.

Plus on your stock car any Dry System is cheaper, and SAFER then a wet system.

[Trancer]

How is a dry system safer? You run the risk of running a lean mixture of fuel. With a dry system, no extra fuel is added. With a wet system, its all controlled by a computer to add extra fuel to keep the fuel/air/nitrous oxide in the right ratio.

Because there is no chance of flooding the motor first of all and second of all the N2O causes more fuel to be pushed into the system which compensates for any possible lack of fuel. Not only that but the fact the the set up is so much easier and I just think that for our cars that dry is safer, well might be different now that the ICCU and DHP are out because you can adjust for it.

wet kit is better! dry kit is safer.


take my advise.... NX is a stronger kit than NOS... bigger selonoids too

Wet Max on 3.4 V6 is 100 shot pill! (safely)

Dry Max on 3.4 v6 is 75 shot pill.. (safely)


i have found that a dry 85 pill vs dry 75 pill on my car made really no difference! maybe .1 in the 8th mile

less is better and safer....... but do to adding fuel a wet kit can run higher amounts....just like fogger kits can run extremely high amounts.

keep in mind that spraying your TB with fuel is not the best way to go on a wet kit....it will cause puddling (as if the shape of our upper intake isnt a big enough problem with the egr etc in the plenum!)

stick with a 75 shot dry....you wont regret it!


and with dhp and iccu you can retard the timing and run larger amounts of N2O but you will need the "new tranny" thingy!

SPAZ....you forgot the #1 buy with nitrous.... a 180 degree t-stat!

your car will run hotter when you use nitrous....it takes forever to cool down between runs with the 195 stock stat!!! but a 180 !

Using the old addage of " Use the search button. " and " Its allways better to post in an existing thread than start a new one!" I felt compelled to bring this dinosaur back to life.

I JUST got rid of my 97 3800 Firebird ( I have 5 kids so my wife got me to trade it in on an 03 Exploder....er I mean Explorer) and before I traded in the bird I snagged my TNT system off of it.

Now off of an SLP Cold air intake and also running the NGK TR6 plugs with 98 octane I was able to still run rich even with a 100 shot dry. I was kinda wondering what was the biggest shot anyone has run on here.

Running that shot in my bird I was able to take out Mustang GT's easy. I was thinking about running it on the Grand Am that I took over from my wife. Its an 02 with 23000 miles on it, I have been the only owner on it. I would love to get yalls thoughts and insight on this.

Oh and I dont know how many of you have ever delt with a TNT system but when they say 100 shot, when it is at the right pressure (1020psi) thats the MINIMUM that you will get at the wheels! Its one of the most potent systems out there if not THE most potent

IIRC tehjohnson says he runs on a 125 shot.

[botlfed]

I ran a 125 drykit for a few years on my 99 gagt
No problems here, it was the 1st known in the 13's

you are gonna need drag radials and I would also suggest a trans interceptor
the tranny is gonna slip badly between shifts if not used.

Never touched the bottle myself Unless there was/is a user named tehjohnson.

That can be looked at 2 ways

all Nitrous companies have different means of measuring tha "HP" amount
depending on the company, they rate it by amount of

nitrous that flows/seconds it takes for that amount to flow


a 100 shot from TNT may flow the equivilant to a 150 shot from NOS, or a 125 shot from NXpress


the only thing I can say is stick with a reputable company

I personally used an N.O.S.(not Nawwwsssss)
LS-1 dry kit on my car and found the 125 shot to be what I liked

I will do some looking around to find each companies different flow rates in determining shot size

oops, wrong person. Now I believe it was radgto that ran the 125 shot. I knew Brandon ran nitrous, I just thought it was less then 125. Damn memory.

safest and smartest thing to do is to take your car to a dyno and test each pill and your a/f mixture.


i ran an 85 dry...with no problems...our stock fuel system is pretty darn good.

wet systems are only better when they are plumbed in the intake not spraying the throttle body...( i have seen many TB sprayed wet systems blow up due to puddling of nitrous and fuel )

dry is safer if your car compensates for the nitrous with more fuel....and GA's have good fuel systems and MAF's to do so!

Great info much appriciated!!!!

TNT is fairly reputable, they are HUGE in F-body circles. For the longest time they had the claim on their web site that they were the only power adder that was putting LS1's in the 8's. They dont have that now but for a couple of years 2000-2003 they did have that claim.

I ran 75 on the Firebird for a while and then bumped it up to 100 with awesome results! So after I get all the safety equipment that i couldnt pull off the bird when I traded her in ( I.E. Window switch, WOT switch, air fuel ratio gauge , ect...) and get an intake an exhaust I'll throw it on the GA on a 75 shot ( thats the lowest setting I got ) and see how she dose. If it can handle more well go 100. We'll see about times after all that .

DC1_01, hey are those your websites? i have admired those firebirds for some time!

i so wanted to do that to my GAGT!


my favorite statement on that website:


"Although at first I was very impressed with the car it did not take long for the performance bug to bite me. I began looking at local race shops and online performance sites but was shocked--there was almost nothing available for my car. It seemed you could build an entire Trans Am from the ground up just by buying race parts but there was nothing listed for the 3.8. Every performance "expert" I spoke to laughed at me for having bought the "worthless" V6. Yet at the same time on the streets I saw Civics and Neons--friggin four cylinder cars--with every performance modification available. I found it hard to believe that there was more interest in modifying a Civic than there was for the Firebird. Finally, I got a break--I stopped by a local muffler shop and the manager convinced me to get a Magnaflow rear section exhaust. It was not much, but it was a SOTP performance gain--and it was a start.

Before long I had also purchased a K&N air filter (in the stock airbox) and a Hypertech 160° thermostat. In November of 1998 I took a trip to Rockingham Dragway and pulled a 15.473 @ 89.36. Not bad for a baseline run, I thought. My interest in the car exploded and along with two friends I founded a local car club, Coastal V6 F-Body, that autumn."
