Nitrous Help

[JayJones]

I was searching the web looking for nitrous. I am told NX is the way to go since ZEX has problems don't know if this is true or not.

I was searching and I came acrossn this Nitrous KIT. Has anyone heard of or even used this kit before because I don't want to screw my car up.

I intend on using this on the track just for a little more get up and go since I am a N/T

My kit is made up (custom) of parts from DynoTune.

They are pretty good, I'd say that the build quality of the components is comparable to NX.

Let me be the first to say GOOD choice!
Going nitrous instead of turbo is a good plan for us NA's.
NX efi mainline kit is the way to go. You can get one for $338.00 shipped to your door from www.streetdemand.com

They are slow getting it to you. About 2 weeks to be exact. They are kinda a new company and they are working on getting established.

Good luck. I decided not to go with ZEX becasue i read more bad things about zex then NX.
I have heard bad things about both leading brands though! Make sure and get an Air/fuel ratio gauge and a oil pressure gauge. If you have a stock motor you need to watch your engine. Also get a little bit colder plug

Yeah I thought about turboing the car but I figured to expensive. The Plan Is Nitrous A/F Gauge (already got oil pressure gauge stock on pooped out) and running high comp pistons. Just got to find high comp pistons for my car should be a fun little project. thanks for the suggestions

Grr I forgot to ask the one thing i really needed to know. What plugs do i run with nitrous?

I disagree with your choice of gauges, and I'll give you the reasons why.

First, the air/fuel gauge you specify is hardly accurate (unless you are talking about wideband), and the oil pressure gauge is hardly useful. A narrowband air/fuel sensor (like that kind that comes on the car), and that plugs into any standard air/fuel sensor, is not accurate enought to tune nitrous. It may glow in the stoich range during a pull, but this is hardly an indication of tune. Also, narrowbands are slow enough to allow you to cause damage before you realize there's a lean condition. Oil pressure is good, but, there's already an oil light in the vehicle.

I agree that you must watch your engine, however, I'd recommend a EGT gauge (Exhaust Gas Temperature), Fuel Pressure gauge, and Nitrous pressure gauge.

The EGT should tell you if you are overheating, or at risk of melting anything right away. A fuel pressure gauge will allow you to make sure that you have enough fuel that you are not running lean. The nitrous pressure gauge will help you (with the added help of a heater and purge) to maintain a specific pressure range for shot consistency.

First I would buy a wideband Second my oil light doesn't work along with the gauge so I had to buy one because running the car with no oil pressure is bad which you know. Which is an autometer from cardomain.com. I plan you running a 35 shot or 50 depending on how good things go. I wouldn't run nitrous without a heater and purge set up anyway. All I really need to know is what colder plugs should i buy.

 

[ShadowWulf]

The heater and purge arent really neccessary. I look at em as nice additions, but you can race just fine without em.

Bottle heaters are now disallowed at some sanctioned tracks/ racing organizations.

EGT, you should have one if you are starting to mess around with any device that alters fuel delivery. If used properly will help you make inferences to ignition timing, which is important when you burn more fuel. Together with a WBO2 offers an extremely useful combination. I personally will be logging my EGT and AF with my Innovate motorsports WBO2/logger this year.
