Important Stuff to Consider

In this section we are just going to BREIFLY throw some things out there that need to be considered.

  • Motor
  • Tune
  • Spark plugs
  • Fuel (Octane and Quantity)
  • Additional Rules / Fire Jacket & Helmut
  • Monitoring and Follow up
Motor

There are specific mods that can be done to the engine that will help the chances of surviving N2O. Things that include special piston rings and gaps to deal with the high temps and pressure of N20, special pistons (including thicker crown & different ring location), forged crank, forged rods etc. Basically don't plan to spray a big shot unless preparations are made before hand. And most important DON'T BE GREEDY, you'll get in trouble quick.

Tune

Its possible that the tune on your truck is going to need to be modified. If you don't remove timing via the tune, you probably will have to remove it using some other method. See the section on tunes here.

Spark Plugs

Your spark plugs need special consideration as well. Heat range, gap and type should be considered. See tune section for more details.

Fuel

Quantity and Quality!

  • Quantity - Depending on the amount of nitrous shot you are running its possible you might need more fuel so keep this under consideration. Once again, different fuel pumps, boosters and standalone fuel systems are outside the scope of this project.
  • Quality - Make sure you run a decent octane level that you are tuned for. With the increased potential of detonation don't skimp on fuel when going to the track.
Additional Rules / Fire Jacket and Helmut

Keep in mind at the track there will probably be additional rules that apply to vehicles running nitrous oxide. Even on a stock vehicle a N20 system will probably put you into an ET range that requires a helmut. Some tracks will require additional items including a Fire Jacket. All the basic stuff applies including a properly mounted, stamped and identified bottle and possibly an externally vented blow down tube. Reading the NHRA rules is a great place to start.

Monitoring and Follow up

The bigger the shot the more critical monitoring and follow up becomes. AFR gauges, reading of plugs, monitoring KR, etc.
