Dry nitrous oxide systems provide fuel enrichment by increasing the fuel pressure to the fuel injectors as the nitrous system activates.
ZEX™ has designed the ultimate Smart Nitrous Oxide System. The ZEX™ Dry Nitrous System, using ZEX™'s patented fuel control technology, reads the nitrous bottle pressure and adjusts the fuel enrichment accordingly. If it is a cool day out and the nitrous bottle pressure is around 700 psi range, the nitrous system will add less enrichment than if it is a warm day and the nitrous bottle is at 950 psi. This unique feature ensures that you always have the optimum ratio of nitrous oxide and fuel, never too rich, never too lean. This ensures maximum power and safety at all bottle pressures. Once armed, the kit is activated at wide-open throttle by a programmable electronic sensor that learns the voltage curve of your TPS sensor. This design ensures your nitrous oxide is engaged at the perfect throttle point every time. The design of ZEX™ Dry Nitrous System makes it the simplest, safest, and easiest to install nitrous oxide kit on the market.
Our nitrous
kit is very universal by design. It works on most late model,
direct port fuel injection kits.
ZEX™
Nitrous Compatibility Checklist
Engine
must have a vacuum ported fuel pressure regulator
Throttle
position sensor voltage must pass the following test:
Locate
the T.P.S. (usually directly across from throttle linkage)
Turn
ignition to on position (do not start engine)
Using
a digital voltmeter, check each wire for a low voltage
reading of approximately 1 volt.
Only
one wire should have this low voltage with the throttle
closed
While
on that same wire, open the throttle completely and check
the voltage reading
If
your voltage reads 4.2 volts or higher, you are ready
to install your ZEX nitrous kit
How
much time can I expect installation to take?
A person
familiar with common hand tools should be able to complete the
installation in three to four hours. If you can get out of bed
by 8, it should be in before lunchtime.
Where
can I get the nitrous bottle filled?
Quality speed
shops will be able to fill the bottle. Alternatively, most welding
gas suppliers can fill the bottles.
Will
your kit work on my car if it does not have a vacuum operated fuel
pressure regulator?
No, our nitrous
kit is not compatible in your application due to the absence of
a vacuum ported fuel pressure regulator. The required fuel enrichment
comes by way of this style of fuel pressure regulator.
My car
has high mileage, is it safe to run nitrous on it?
High mileage
is not necessarily an indicator of a car's mechanical condition.
The better mechanical condition your car is in, the safer it is
to use any high performance product. If you are not sure on the
condition of your vehicle, take it to a qualified mechanic in
your area for a complete inspection.
How
much horsepower does the ZEX™ kit add?
The ZEX™
kit is adjustable in three horsepower increments. Jets are provided
that will give anywhere from 55hp to 125hp, depending on which
kit you purchase.
Do I
need to upgrade my fuel kit to use your kit?
Our kit
was designed and tested for use with stock fuel kits. It will
perform properly on stock and mildly modified engines, i.e. header,
K&N filter, exhaust, etc. If major modifications have been performed,
i.e. camshafts, heads, porting work, intake manifolds, etc. It
is strongly recommended that a fuel pump and injector upgrade
be performed on your engine before using your ZEX nitrous kit.
Do I
need to use different spark plugs when using the ZEX nitrous kit?
It is highly
recommended that you install non-projected nose style spark plugs
that are 2 heat ranges cooler than stock plugs. For best results,
use our Hyperformance™
triple electrode spark plugs. These spark plugs were designed
specifically for nitrous, turbo, and supercharged applications.
How
long will one bottle of nitrous last?
This totally
depends on which jetting is used. The 55hp shot will last around
3 minutes of continuous use. The 125hp shot will last just under
1.5 minutes of continuous use. Generally, since each race lasts
less than fifteen seconds, many races can be run from a single
bottle.
What
makes your ZEX™ kit better than other brands?
Our kit is
self regulating and adjusts fuel pressure according to bottle
pressure.
It is TPS
activated, which means no throttle switch brackets to rig up.
The control
box houses the solenoid for a cleaner installation.
We include
a one year warranty on our Zex kits.
The convenience
of toll-free support.
Finally,
we are confident that our kit is the easiest on the market to
install.
After putting the Zex Dry Nitrous kit in my car I was totally amazed. Install took about 2 hours like said. The only problem with this product is that I have to have it in every car I own!

This is the best nitrous system for your car, because it is the easiest to install and the zex management unit always monitors and adjust's air/fuel ratio. I have used and installed this kit in over 4 cars. Never a problem, and the power gains are great.

I speak from experience when i say this kit has all the power you'll ever need in a nitrous kit for the street and is made for the do it yourself tuner. Only took me a little under an hour to install. If your looking for the best bang for your buck with the least amount of head-aches, this is definetly what you want. PERIOD!!
