hello everyone and welcome to this
week's video today i'm going to be
explaining nitrous and how nitrous can
be used to increase horsepower now
nitrous express was kind enough to send
me a full nitrous kit for the use of
this video so to help me explain this so
after i demonstrate with this white
board how it works we're going to take a
look at an actual system see all the
components involved and see how that
works
so nitrous oxide the purpose of a
nitrous system is to increase horsepower
now how it does this is by allowing the
engines to burn more fuel per power
stroke now how does it allow the engine
to burn more fuel well it increases the
amount of oxygen inside of the cylinder
during each power stroke so
what we've got here is a plate type
system now there's multiple uh ways you
can you can do this but for the
demonstration here what we've got is a
plate and this plate is between our
throttle body and our intake manifold
and you've got injectors you've got fuel
solenoids and a nitrous solenoid so
these are going to control the flow of
nitrous and fuel which are going to be
injected into this plate sandwiched
between the throttle body and the intake
manifold
so
here we've got uh and you've got
individual injectors as well now there's
two types of nitrous systems there's dry
systems and there are wet systems now a
dry system is going to be just nitrous
injection and it's going to have to be
used with electronic fuel injection
because as you're injecting the nitrous
you're going to have more oxygen your
cylinders now you'll have an overly lean
mixture so obviously you need to burn
more fuel so your ecu is going to tell
your fuel injectors hey you need to
inject more fuel and it's going to do
that by listening to the oxygen sensor
in the exhaust that's saying hey there's
too much oxygen coming through here
you're burning a lean mixture we need to
fix this
so it doesn't react quite as quickly as
a wet system where you've already got
the correct amount of air and fuel so as
i just said a wet system you're going to
be injecting nitrous and fuel
so this is a wet system here where
you've got nitrous coming in on one side
of this plate and fuel coming in on the
other side of the plate now you're also
going to have individual fuel injectors
for each of your cylinders or it could
be carbureted and then you'd have
another system of fuel coming in
regardless there is going to be there's
going to be fuel that's going to be
burned with the air that's coming in and
then there's going to be fuel that's
going to be burned with the nitrous
coming in so it's constantly correcting
that air fuel mixture and you're going
to keep the right amount of air and fuel
in each
in each cylinder during the combustion
process
so
what's the process starting at this
plate well you're going to be injecting
the nitrous and the fuel into the intake
manifold now what happens when that
nitrous and fuel is injected into the
intake manifold is the nitrous which is
coming in as a liquid once it's sprayed
in it changes to a gas and when it
changes state it drops its temperature
to minus 127 degrees fahrenheit so what
that does is it cools the entire intake
charge therefore allowing you to pack
more air and fuel into each cylinder and
then
you're going to increase your horsepower
so that's one way that it helps increase
power
also our next step what we've got is
the cylinder is compressing what you've
got is a nitrogen uh two nitrogen atoms
and one oxygen atom fused together so
that oxygen can't combust when it's
connected with that nitrogen so it has
to be split free uh to be able to
combust with the fuel
so what happens is during compression
and during combustion when that air fuel
mixture is heating up once it reaches
about 600 degrees fahrenheit that oxygen
splits off and once it splits off it can
combust with the added fuel
so you've got
more oxygen you've got more fuel
and each and in the same power stroke
this is occurring so you're going to
create a larger reaction larger
combustion bigger force pushing down on
that piston and therefore create more
power
so now let's take a look at what the
actual system looks like and how the the
flow of nitrous gets here and how the
flow of fuel gets there and how the
system works
so here we have our full nitrous kit and
we're just going to start at the bottle
and work our way up and just check out
the different components see how they
all work together to increase horsepower
so starting with the bottle you're going
to have these mounts and it's going to
be mounted somewhere in your car as i've
shown here with the bottom of the bottle
is going to be lower than the top reason
being there's a siphon down here which
is going to be pulling the liquid
nitrous and sending it to this line
which will then come to your plate
sandwiched between the throttle body and
the intake manifold
and here you've got the mechanical
solenoid which when activated will allow
the nitrous to spray in through these
little holes you see here
now on the other side you're going to
have a fuel line so you're going to have
your fuel line coming in here and then
this is going to lead to the fuel rail
injector which will be injecting fuel to
the engine directly
and then you've got this fuel line which
will pull in additional fuel to this
plate
and so then you've got another
mechanical solenoid which when activated
will spray the fuel in through these
little nozzles here or these little
holes here
okay
so then we've got some electronics
involved so what activates this is when
you're on wide open throttle
so
when you're on wide open throttle you've
floored it basically
you're going to have this sensor here
which is going to be attached to it's
going to be wired to the throttle
position sensor so when the throttle
position sensor reaches its maximum
voltage or the highest
highest setting on the on the throttle
it's going to send a signal to this and
this is going to send a signal
to this relay now this relay is what
sends power to these solenoids so once
this is read that the throttle position
sensor is at wide open throttle it sends
a signal to this relay this relay is
connected to the battery and so it sends
a power supply from the battery to these
mechanical solenoids opening them up and
allowing the
fuel and nitrous to be injected
now
here we just have the little cool button
that you see in all the movies and
everything
so basically this is just going to arm
the system that'll be connected to this
throttle position sensor
and it'll say okay when this senses that
wide open throttle has been reached then
you will activate the solenoids you can
just leave it off and then still get to
wide open throttle and it won't send in
nitrous
now the cool thing about nitrous kits is
how easily you can change the amount of
horsepower that your engine is going to
produce so you've got these little uh
brass jets here which are located inside
of
this floor connection
so for example here's a little brass jet
and you simply stick this brass jet in
here and then connect the fuel line and
so you'll have a brass jet one for the
nitrous and one for the fuel
and depending on which jets you choose
is how much horsepower you'll create so
for example these two here you'll create
you'll add an additional 50 horsepower
whereas these uh down here you'll add an
additional 200 horsepower so you can see
these are not the nozzles for the
nitrous system
and you can see how much larger they are
than the fuel injectors or jets and
that's so obviously you're going to be
having
more
nitrous injected than fuel
so thanks for watching and if you have
any additional questions or comments
