Second Guessing Using Nitrous, Help Me Out Well I am beginning to peice together my wet kit, I recently bought a NX EFI kit, Dynotune heater, NX filter. Soon I am purchasing a NX purge, Nitro Dave's plate, dynotune controller, but now I'm second guessing using Nitrous. I plan on running a 150 progressive hit using dynotune's controller and a micro switch. I'm kind of worried about popping the engine, everyone I tell I bought nitrous says "your going to blow the motor up", which I'm pretty sure I won't but It just the voice in the back of my mind. I know my car can handle it (12 bolt, racetronix kit, 42# injectors, etc.), just worried about the engine. I know the proper bottle psi is 900-1000, I'm using a autometer fuel psi gauge in the pillar, I plan on running a fpss. I have all the safety stuff, but still am a little worried. Anyone wanna help me out?
I know how you feel. I can't exactly drop $5k+ on another engine for mine, but decided to go for it after doing all the research I could. So far so good... Just get a good tune and you should be fine. Always good to have a little mad money set aside or some other backup plan, just in case though.
I agree with a good tune you will be allright, a Wideband would also help watch whats going on with your motor...there is a group purchase in this section for one if you want to check it out...but anyway, good tune and don't forget the tr6 spark plugs and you will be allright. Good Luck. 
do it robbie. the nitro dave plate kit is a nice piece i have the dual stage plate sitting in my room. you will be fine with that small of a hit. let me know at the meeting if you need any parts i may have extra stuff laying around.

The biggest things I still need is the plate and the progressive controller, I have just about everything else. I need a microswitch, solenoid bracket, nitrous daves ashtray switch, and some more braided line. Thanks slink

I like to pull some timing on nitrous and still have max timing all the time n/a, so I'd recommend a timing tuner as a tuning and safety device. Why a progressive controller? Purge also isn't really a necessity. looks pretty though. I've run hundreds of bottles of nitrous through my cars over the years on wet kits w/out an incident.
Did lose a motor on a dry shot, but it was super lean as the maf didn't recognize the spray. Never hurt anything on a wet kit.

Personally I'd forego the progressive controller and pick up an FJO dual channel wideband. It will do extra duty as a window switch, microswitch (from what I'm told) and it will shut the nitrous down if you go too rich or too lean. I'm getting the goods together right now for my cam and TNT kit. 
I've been in the same boat as you for quite awhile now. I had an NX MAF kit about this time last year, but I got cold feet and sold it. I just got my TNT kit monday. I spent alot of time on here looking at what all the resident nitrous junkies had to say. From what I gather if you;
- Have a good tune
- proper safety equipment (which will likely cost as much if not more than the kit itself, but if it saves the motor it's worth it IMHO)
- Don't get greedy with the size of the shot
- Finally properly maintain, the system, safety components as well as keep any eye on your plugs, knock etc...
Everything should be A-OK.
Just my .02

well from what people tell me a progressive hit will be a little easier on the engine, which is what I'm going for. I will look into the dual channel wideband, that sounds pretty nice. 
I agree the progressive controller would definitely soften the hit. I've been trying to research that myself. Mainly because the tracks I usually (am forced) to frequent aren't prepped worth a damn, and I'll have to have a controller to ease the juice on so I don't blow the tires off. This is going to be one hell of a test n' tune year for me... The N2O is in the garage awaiting install, and I just ordered a cam package and the rest of my bolt ons from Texas Speed today.

yea well now I'm reading about progressive shots tear up the noids after a while. Would be ok to shoot the 150 all at once. I was looking into 2 stage but that's kind of expensive. Guess I gotta rebuild the noids each year
