Nitrous oxide has come a long way as a reliable power adder over the last few decades. With the emergence of drive by wire vehicles, like the S197 Mustang, nitrous companies like ZEX have had to adapt from window switches to TPS voltage activation to accommodate for this technology. Also, dyno testing every kit is where ZEX says they separate themselves from the competition; not all engines are created equal and having specifically-tuned jet sizes for your application is a huge plus.
Everything you need comes with the ZEX kit; even a specifically-designed fuel rail adapter that will feed the fuel solenoid.
ZEX originally started making dry kits in the late 1990’s, that added additional pressure to the fuel regulator to keep the motor from running lean as a form of fuel enrichment. Since then, they have condensed the size of their Nitrous Management Unit (NMU), engineered a wet kit, and started making application-specific systems. Having an application specific system not only allows ZEX to make sure the jetting is spot on for that motor, but also that any special fuel rail adaptors are included.
Self-Learning TPS Calibration The NMU incorporates a TPS sensor voltage calibration button. Simply flip the toggle switch to power the NMU, press the program button for one second, and then mash the throttle (of course with the car off, but the key on). Once the NMU blinks “red, green, off” then the NMU is programmed.

We took the ZEX kit over to local shop Cunningham Motorsports (CMS) to have the nitrous kit installed on a 2011 Mustang The Mustang has a full exhaust with cat delete, JLT intake, and custom Cunningham Motorsports tune. The resulting mods allowed the Mustang to produce a respectable 416 hp and 401 lb/ft to the tires.
Everything you need comes with the ZEX kit; even a specifically-designed fuel rail adapter that will feed the fuel solenoid. The adapter also features an additional 1/8” NPT port so that you can install a fuel pressure gauge. The fuel and nitrous solenoid, along with all the electronics are housed inside ZEX’s NMU box.
Part of the NMU’s electronics is the throttle-by-wire activation that hooks directly to your TPS sensor and includes a resistor to keep the motor’s PCM from throwing fault codes. Outside the TPS wire, a simple toggle on and ground wire is all the wiring you need to do.
By The Numbers
Before: 415.5 rwhp and 400.8 lb/ft
After: 483.8 rwhp and 498.6 lb/ft
Gains: 68 rwhp and 98 lb/ft
The 75 shot did exactly what it was suppose to do, generate an additional 75 hp to the flywheel, which translated into 68 rwhp. The big jump occurred on the torque curve, which increased by 98 lb/ft. “On 75 horsepower, you really don’t need to change spark plugs or anything like that. The only thing I’d suggest is to make sure you’re running 91 or 93 octane,” explained Patrick.
Nitrous is no longer a “black art” that requires a special installation from an expensive shop. Virtually anyone with an average set of tools can install this very same kit in their drive way over the course of about three hours. Keeping your activation RPM over 3,200 RPM and off the rev limiter will be the two main safety goals when running a nitrous system. Also, retarding the ignition timing based on the shot size will help prevent detonation. Now, this mildly modified Mustang can go from running low 12 second passes to mid 11s with just a simple flick of a switch.
