!  Use sealant of any kind on AN type fittings.
     !  Allow nitrous pressure to exceed 1100 psi.  Excessive pressure can cause swelling or in extreme cases
        failure of the nitrous solenoid plunger.
     !  Inhale nitrous oxide.  Death due to suffocation can occur.
     !  Allow nitrous oxide to come in contact with skin.  Severe frostbite can occur.


     Chapter 1.  Introduction to your DynoTune Nitrous Oxide Kit

     1.1  General Information on Dry Nitrous Injection

     This kit is intended for 4 & 6 cylinder EFI applications with engines using a MAF (Mass airflow sensor).
     When Nitrous oxide is injected before the MAF sensor the cold Nitrous passes by the hot MAF sensor wire
     cooling it down. This fools the cars computer into thinking it has a lot more air is going into the engine, thus
     the computer adds extra fuel to compensate for the air or in our case Nitrous Oxide. This extra fuel is
     injected into your engine by your OEM fuel injectors. Both the nitrous and Fuel combine in the chamber to
     give a “Liquid supercharger” effect.

     NOTE: You must use a stock calibrated MAF sensor, a MAF that is not stock may need special tuning to get
     the A/F ratio correct. See the advanced tuning section. It is up to the Operator of this kit to verify that this kit
     is compatible with their application.

     These kits have been designed for safety and smoothness of operation.  Nitrous oxide is injected into the
     engine only when the following conditions are met:

     !  Bottle valve is opened
     !  System is armed
     !  Engine is at wide-open throttle

     Horsepower and torque increases due to these kits will vary with engine displacement and modifications.
     Approximate power increase estimates can be made based upon the massflow of nitrous oxide into the
     engine.  The following table is provided to allow you to estimate the power increase you can expect for your
     application.  DynoTune strongly suggests that an upper limit of about 40% increase in power output from
     your stock engine.  Exceeding this can result in premature engine failure.

      NOTE:  If jets other than the ones recommended in the table are used, please refer to Chapter 3, “Baseline
     Tuning Suggestions” and Chapter 4, “Preparing for Operation”, for additional information on jet selection.
     NOTE: Jetting higher than 35hp on 4cyl cars is not recommended without fuel system upgrades and
     professional tuning.
     Drivability, fuel economy, and exhaust emissions should not be affected under normal (part throttle)
     conditions.
