NOS Nitrous Oxide Systems: Under Carb Plate Injector Installation and Test

I Install and Test a 150 HP Under Carb Nitrous Oxide Injection System

    When you decide to make the leap to N2O (nitrous oxides chemical name and common slang) there are a few things you need to know before ordering your kit.  You need to ask yourself the following questions:

1:  How much of a power increase will my current engine sustain?
2:  How much Money do i want to spend?
3:  How will this affect my insurance?
4:  Do i have a local source for Nitrous gas?
 Lets break down each question one by one and then we'll get on to the installation.  

#1  This is a question for tech support at NOS.  They will need your engine specs including cam numbers, compression ratio, type of exhaust and intake manifolds and fuel deilvery (carb or EFI).

#2 The amount of money you want to spend is up to you.  A basic plate N2O system can be as little as  $750.  A complex double solenoid, double nozzle fogger system can run you $5000.

#3  How a N2O system affects your insurance is dependant on the company.  My Ranger is insured with state farm and the installation caused no increase in the premium.  I helped a freind install a system on his Civic and his monthly insurance bill DOUBLED!  IT pays to check this out before you buy.

#4 You will need to have a source for Nitrous gas at a local level.  Most Carquest and NAPA stores will send your bottles in and have them filled.  Some local "speed shops" fill them on-site.

Now on to the installation!

First and foremost is safety.  NEVER EVER inhale N2O gas!  This gas displaces oxygen and inhaling it can lead to brain damage and possibly death.  DO NOT play around with your tanks.  If the bottle valve broke off from being dropped or tipped over you could be seriously injured or killed.
