How to understand
car and bike Nitrous Systems!
Road or Race, Wild or Mild.
Or how to build your own
Nitrous kit from scratch
for very little money should you wish to! How it all came about 25 years ago
A great many have done this successfully & reliably and
safely after reading these very pages over the last ten years or
Don't worry its quite easy
if you are fairly bright,
its cheap & safe* & interesting once you have read & understood
all of these pages! (with some obvious
And these pages are in no particular order and the titles are often
misleading - So read the bike Nitrous System pages even if you have a car for
example. You need ALL the information.
*Don't try building anything yet
though, especially filling tanks and bottles, until you
REALLY have grasped the finer details or it actually could
be very dangerous! Knowledge really is power as well as
safety in this case! Perfectly safe as long as you understood the parameters.
Nitrous Oxide (N2O) is MUCH more effective
in creating more power safely and cheaply than
any conventional engine tuning work ever could be. And its transferable to
your next car or bike too. And no unlike the film "The Fast and the Furious" it
isn't going to damage your motor or scare you! Unless you want it too...
- Power Curves.
stock Suzuki 1100 WP for example
Its brand new here & not run in yet, 2 Power Runs - one
STOCK and one with one
of my cheap DIY Nitrous Systems operated at 7400 rpm...
A safe 190bhp at the rear wheel. Once it had colder plugs fitted, and a straight
through "loud" exhaust it was well over 200bhp at the rear wheel. This is
typical. Works just the same on cars too.

This is the same two runs on the Dynamometer but
displayed as a torque curves. This is actually a better demonstration and more
relevant. The rate of acceleration is the
thing as the torque produced so this is
what you would actually feel when you hit the button as acceleration rate.
Feels like a truck ran into the back of you but it keeps
on going! This bike
already did 0 to 100mph in under 5 secs. Imagine how it feels now!
And this was just 50 extra
bhp, 150 bhp extra is quite feasible if you wish...

You can make your own car / bike much faster!
Cheaply and easily, without all the disadvantages and cost of normal
engine tuning work like cams, cylinder head porting,
pistons, carbs or chips and manifolds etc. Far greater BHP increases for
the money! And when you are not using the Nitrous
System the car is still the same smooth quiet standard
vehicle it was before. Unlike a "tuned" car that is a
horrible thing to drive for the majority of the time on the
If you use a manufactured Nitrous Injection
System such as Holly, NOS, High-Power (WON), Cold Fusion, Zex, NX or Nitrous
Express or any other of the now dozens of clones then you will be able to
understand the differences and the shortcomings of the US clone systems and
"Dry" systems. Or just learn about Nitrous Injection in detail generally.
So... If you have a little intelligence,
can read, and understand a little simple physics - you too can
build your own reliable, safe, powerful Nitrous Oxide
Injection Kit very cheaply and professionally. All the info you will need is on
these pages... But you need to read every page
other than insurance and links.
More importantly though, you will
Understand how everything works in detail and it will
cost you far less... Typically £120 UK Pounds or $20 US Dollars for a full neat and tidy DIY
Nitrous system, with
up to 140 BHP extra power! And it will be a better
system design for a large number of reasons than a typical
US designed Nitrous System (NOS kit)
That's seriously cheap and CONTROLLABLE Horsepower! Especially if
you fit more than a single stage, or do more than one vehicle.
Or fit a Pulsed Controller.
Maybe you will just prefer to save
yourself the work and time, and simply buy a Nitrous Kit off the shelf,
but either way, the unbiased
information contained on this site will be very useful to you
whatever make your kit is! All of the current US based
systems are now very old designs, with obvious shortcomings
but seem to have a mass following of people "swearing" by
them regardless! They just don't or won't see
I have been building Nitrous Kits
and testing systems for 20 years or so now, ever since I got
hooked! Mainly as a hobby. And believe me, the US
based systems have a good few design problems... Especially
on smaller engines or pulsed controller (P.W.M..) type systems. Your DIY
system can avoid these problems and I can show you why most of the
"others" are badly designed at the same time.
How Nitrous Works (simple quick version!)
Nitrous oxide systems make additional horsepower by
allowing an engine to burn more fuel than it could normally do.
Burning more fuel creates higher cylinder pressures that will
push down on the pistons with greater force. This gives
much more power! It does this by adding extra oxygen in a

operates whenever you want it to, By pushing a button, or at
full throttle - you can choose when and for how long. It will
NOT hurt your engine if set up carefully and
reasonable amounts are used!
Nitrous Oxide is stored in a metal tank or "bottle" in the boot (trunk) of
your car. It is a compound of Nitrogen and Oxygen. When it
gets heated up inside the engine during combustion, it breaks down
from the Compound N2O
called Nitrous Oxide or N2O (NOT NOS that's
a company) into two separate gasses, Oxygen and
Nitrogen. This is a good thing! Because the extra oxygen now present
allows more fuel to be burned and the Nitrogen although
"inert" absorbs the extra heat and expands...
The extra fuel that is now also
required is injected at the same time as
the N2O via an additional solenoid valve and injector
into the intake system. This is carefully
metered with a jet to ensure that exactly the correct amount is added. Its a little
more complex than this, but that is a basically all there is
So YOUR car can have
Nitrous Oxide Injection (*NOS) added easily and without
any damage or other drama!
Actually almost any car, bike, plane, jet-ski, snowmobile,
micro-light Aircraft, lawnmower can too!
Although I am going to fit my own home built system
new minivan over here! It really needs it...
the term NOS is incorrect as this refers to an specific
company (called Nitrous Oxide Systems, in the US)
