Getting the most BANG for the BUCK $$$
Nitrous is the answer!
How much money would you have to spend on an
engine to gain an additional 30 - 40 in power?
Using this bike for an example: It is a typical
low budget mild 95 ci build using mild ported
heads, a good camshaft, good exhaust, SE air
cleaner, and a 50mm T/B.
It has a HP gain of 41.48 and a TQ gain of 49.52 using a .030 jet.
Just think of what it would cost to gain this much power
without nitrous. This engine still has the drive ability, reliability,
and cruising fuel mileage without major stress that is created on
engines with huge cubic inches, extreme cams and compression ratios.
When you want the power, just flip the Master Switch
on and open the throttle to 100%.
How Nitrous Works.
First, let me ask a question:
What is the primary purpose of: using larger throttle bodies, porting heads,
larger cam lobes, larger cubic inches, larger valves, free flow exhaust, tuning
an exhaust, tuning the induction system, adding a turbo...?
Answer: To increase the oxygen content in the cylinder as much as possible
(of course adding the correct amount of fuel to the oxygen). Also, there isn't
any Nitrogen being added to help dissipate the the heat being created.
The more oxygen added (with the correct amount of fuel) to the cylinders,
produces more power. Just think of how much that you spend on these types
of performance modifications to increase power.
Sometime, calculate the amount you have spent on modifications compared
to the amount of power that you gained. Divide the amount of money spent by the amount of power achieved. This will give you a power/cost ratio.
The purpose of Nitrous is to increase the oxygen content in the cylinder.
So it basically achieves the same result without all of the extreme modifications.
Of course if you already have these modifications, you will naturally have
even more power by adding Nitrous.
How Nitrous Increases Power:
Nitrous increases power in two ways. First is by increasing the oxygen
content inside the combustion chamber. Nitrous is made of two parts nitrogen
and one part oxygen (N2O). The oxygen molecule is separated from the two
nitrogen molecules by heat and compression during the combustion process.
Now that there is more oxygen added to the fuel mixture, you have to add more
fuel to correct the A/F ratio. Adding more oxygen and fuel, results in an increase
of power. Some people ask “Why not just inject pure oxygen?”. Pure oxygen
is extremely flammable and dangerous to handle. N2O is not flammable and is safe
to handle. The second way that nitrous increases power is by lowering the
temperature of the A/F charge which results in a more dense air fuel charge.
Remember that this is the gas that a lot of Dentist use.
The air that we breath normally consist of:
*20.94% Oxygen
*78.08% Nitrogen
*Less than 1% of other gasses
Nitrous Oxide consist of basically the same gases that we breath except it
has about 36% more oxygen. The two parts of Nitrogen acts as a buffer and
absorbs the heat that is created by the extra fuel and oxygen bring added.
Injecting Nitrous also lowers the temperature of the air/fuel mixture. A drop
of 10 degree Celsius (50 degree Fahrenheit) can add up 2% gain in power.
Nitrous can lower the A/F charge up to 40 degrees Celsius. That could be
an eight percent increase in power just by the cooling effect.
There are a lot of misconceptions about nitrous. One misconception is that
it will destroy the engine. This misconception comes from seeing drag racers
blowing their engines while using nitrous. People don’t realize that drag racers
are using extreme nitrous systems on these engines. These systems use multiple
stages with multiple bottles and 500 + HP jets.
A .030 jet is considered to be very mild in the nitrous industry. That .030
jet will add approximately 30 horses to the engine.
The other reason of engine failure is caused by people adding nitrous
without adjusting the proper fuel mixture (air / fuel ratio). This also occurs
when people performs extreme engine modification to gain power. If you bore
the cylinders, raise the compression, add free flowing induction and exhaust
systems without correcting the AFR, The engine will blow up also.
The only real precaution that needs to be taken when using small size nitrous systems is, making sure that there is enough fuel being added so that the engine won’t run lean.
Think about this:
How do you increase power in an engine without nitrous?
Basically you make modifications to the engine that will allow the
engine to flow more air through it. More air contains more oxygen.
How does flowing more air through the engine make more power?
By increasing airflow, basically does nothing more than adding oxygen to the engine.
When you increase airflow (add oxygen) you need to increase the fuel to the
mixture, which results in an increase of power.
This is the same exact thing that Nitrous is doing when added to the engine.
Here are some advantages to nitrous:
Nitrous systems cost a lot less than building an engine to get the same
amount of power. Your biggest bang for the buck.
When you build an engine to make more power you usually have to increase
the valve lift, compression ratio, larger valves, heavier valve spring pressure,
port the cylinder heads, stroker crank, bore the cylinders…
All of these modifications add stress to the engine not only while running the
engine is being run hard but, also during normal riding. Think of it this way: When
you install a high performance camshaft such as a .600 + lift, it pushes the valve
open future. This compresses the valve spring much more than intended
compared to stock. If you plan on increasing the rev limiter, you have to install
even stronger springs. Pushing the valve open future with a higher lift camshaft
and installing stronger valve springs creates more pressure and stress on cam
bearings, camshafts, lifters, push rods, rocker arms, valve stems and valve
guides. The pressure and stress is always on the engine whither idling, or wide-open
throttle. Yes this can increase your engine’s power, but it also shortens the life
of the engine due to the increased stress from the engine modifications the whole
time that the engine is running.
Adding pressure and stress, will also lower the fuel mileage. If these modifications make the engine harder to turn over by hand, then you can naturally assume that it takes more power for the engine to turn itself. Just as turning on the air condition of an automobile, robs power and lessens fuel mileage. Again, to increase power, you have to increase airflow and fuel (open the throttle more). This means you have to use some of the engines power to turn the engine. When it is harder to turn the engine, you will use more power and fuel.
Like a performance modified engine, nitrous will also add stress to the engine (basically only through the crankshaft and drive train). The advantage is that it only occurs while the nitrous is engaged. Again, no more stress than an engine built to make the same amount of power.
The engine doesn’t know the difference between 30 horsepower being added by
heavy engine modifications or by nitrous. The nitrous will still let you keep
your cruising fuel mileage and engine life.
Again, nitrous is doing the same thing as adding airflow (oxygen) through major engine modifications. Whither you increase oxygen through major modifications or by adding nitrous, they both need the correct air / fuel ratio. 30 horse increase is the same whether
by modifications or by adding nitrous.

Again...nitrous puts no more stress on an engine than an engine that is built for the same amount of power.
