Once nitrous is sprayed into the engine it's converted into a gaseous form (it's in a liquid state when stored at a pressure between 700 and 1,100 psi). The fun comes when the oxygen is freed up to light off the abundance of fuel in the combustion chamber. As we all know, the internal combustion engine relies on air, fuel, and spark to essentially create useable combustion and drive the piston downward to rotate the crankshaft. A larger amount of air and fuel, when compressed and burned efficiently, results in more horsepower and torque.
We hustled down to JDM Engineering (Freehold, New Jersey) to install this kit on an automatic-equipped '06 Mustang GT. The NOS kit is adjustable, allowing the user to choose a 50hp or 75hp hit of nitrous-just the right amount of power for this automatic Stang to whoop up on the other S197s (read: "the stick-shift variety") that have been invading the local tracks as of late. We effectively took the Stang from 269 rwhp and 296 rwtq (JDM cold-air kit, custom tuning, and after-cat exhaust) to 329 rwhp and 447 rwtq (50hp shot) and 347 rwhp/454 rwtq with the larger 75hp hit. It took Shawn Lacko, ace JDM tech, less than a day to install the kit, and that was with us stopping him every step of the way for photographs.
Old-school tricks in the most modern Mustang still yield traditional and quick results. Nitrous is the perfect drug.

Lacko Attached the line to the bottle so he could accurately lay out the nitrous line. NOS provided more than enough line to reach the front of the car. |

It was run underneath the car, and every foot or so Lacko tied the nitrous line using line clamps. He then removed the inner fender to gain easy access to the engine compartment. Reinstalling the liner provided protection and hid the braided line from prying eyes. It took a little longer, but the finished product was well worth the extra effort. |  NOS Includes a stainless steel...  NOS Includes a stainless steel fogger nozzle in the kit. This is the Soft Plume nozzle, one of the more popular nozzles on the market. |
 Nitrous Oxide and fuel are...  Nitrous Oxide and fuel are mixed together at the tip of the nozzle. Atomization of the fuel and nitrous is important, and nitrous companies spend considerable time perfecting the tips of their nozzles. Fuel and nitrous are sprayed at two different psi levels, therefore the design of the tip is important to the proper mixing of the two chemicals. |  These Are the jets used to...  These Are the jets used to restrict the nitrous and fuel flow into the nozzles. NOS provides the proper nitrous and fuel jets for the given power levels. Supplied were nitrous/fuel jettings for 50hp and 75hp shots of juice. |  Here's The drive-by-wire setup...  Here's The drive-by-wire setup on the side of the throttle body. The computer plugs into the throttle body and tells the electric motor what to do based on the gas pedal position. As a side note-for those who don't have an aftermarket computer tune, getting a tune-up greatly helps throttle response and overall feel, not to mention makes it run quicker. |
