- Today, I have a little bit (relaxing music)
of a different video for you guys.
We're going to be discussing what gives you
that extra PSID or boost, that EA-5 punch to your fuel,
that nitrous oxide to your intake valves.
That's right guys, power stacking.
What's going on guys?
I'm Nick with Custom Offsets,
Custom Offsets TV on the YouTube.
In today's episode, we're going to be all about
how to maximize the potential of your intake,
your cold air intake, what intakes work well
with other performance mods and what you might consider
bundling together at the checkout cart.
Now break this up into two different categories
based upon their level of difficulty.
First on our list, we'll start with the easy route.
And I say easy, because these are bolt-on or plugin mods
that anyone can do with basic hand tools.
That's why I choose to start every build
with intake and tuners.
Generally, all you'll need
is a Phillips or Flathead screwdriver
and a 10 millimeter, 13 millimeter socket
for most applications.
These two pair up nicely, because if you install
an air intake like SMB or AFV they are allowing
more cold air flow into your engine,
and your trucks stock computer
can only adjust so much for the new air flow.
An intake will provide you with additional performance
but if you simply just install an air intake
your truck still thinks it has restricted factory air box.
So the air flow mapping can only be adjusted so far.
So if you remap your ECU with a tuner
like Bully Dog or Edge, the remapping will widen
those parameters, allowing your engine's computer
to now be able to adjust for the new air flow,
which we all know gives you more horsepower
because of the colder, denser air.
You are basically allowing your computer to adjust from,
say this amount to this amount.
Not only are you gaining extra horsepower
over them being installed separately
you are also gaining throttle response
and in a gas or diesel turbo application,
faster spool times, more turbo noise
because you don't have the factory sound dampening
and who can say no to more turbo noise?
(transition whooshes)
All right, guys, I did want to just kind of show you
just a little bit of a visual reference
as to what I mean when I say restricted air flow,
and with the mapping.
So both this cold air intake and this stock intake
are from a 5.3 Silverado.
Now this stock intake, So as you can see,
all of this is designed for sound dampening
to make the inlet quieter
and it is causing a lot of restriction.
So once you get to the air box,
so this is the tube that leads up to the engine.
So this is your air box, and your only air coming in
is through this little section here.
So with your map sensor here, it's only adjusting
for the air flow that is here.
So when you change to a aftermarket cold air intake
and you put the stock map sensor back into
the aftermarket location, there's gonna be
a lot more air flow coming in
and with the stock map sensor, the sensor can only adjust
for small parameters because this intake
can only bring in small parameters.
So if you just slap on a cold air intake
you're not going to get the true performance
out of that cold air intake.
So that's why when we pair a tuner
it's going to change the mapping.
So the mass air flow sensor, it's going to change
where it's going to allow the new air flow to come in.
So your stock computer can only allow
for just a little bit of air flow.
So now with the new air flow, you're changing the ECU
and the mapping to adjust for that new, greater amount
of air flow coming again with a cold air intake.
(transition whooshes)
Now, if you're not looking to spend the extra money
on a tuner, you can pair a cold air intake
with the throttle sensitivity booster
like we did with our power-wakened build.
We installed an AFE Magnum intake
with a Banks Pedal Monster.
Pairing these two allowed us to get
the extra horsepower from the intake,
but with an adjustable, more responsive throttle.
We ended up going with Banks because they offer
adjustability and safety features over their competitors.
Options like Bluetooth for easy monitoring or active safety.
So in the event of an internal or external circuit failure
the system seamlessly returns the pedal to stock.
When other devices fail, they leave the vehicle inoperable,
leaving to dangerous situations.
Imagine losing power while passing on a two-lane road
while heading into oncoming traffic.
This is why we chose to have Banks
at the control of our throttle.
Now to get into some more
of the slightly difficult performance duos.
Now, these may not be difficult for some
but it definitely makes things easier
when you have a lift to operate on or a nicer socket set.
I'm not talking about that set you borrowed
from your dad either, that's missing the 10 millimeter
and the rest of the chrome sockets
are all rounded out by an impact.
Y'all know who you are.
Air flow numbers and cold air flow
are key for a turbo truck's performance
whether it's gas or diesel.
Lower temperatures mean the molecules
are more densely packed allowing more fuel
and more air and more power.
So let's lump intercoolers with intakes
since an intake connects to your turbo inlet
and your intercooler piping actually connects
from the turbo inlet or, sorry, from the turbo outlet
ultimately going to your engine.
So we will lump these two together with the tuner.
There are two different types of intercoolers.
You can have air cooled and water cooled.
Most of the time diesels have a water cooled or air cooled
and gas engines generally just have an air cooled.
The sole purpose of an intercooler is to cool the air
before entering your engine.
As we know, cooler air is more dense,
making it oxygen rich, more oxygen equals
cleaner burns, and more power.
Let's take a look at the 6.7 intercoolers
for the Powerstroke from Mishimoto.
Those intercoolers will generate
an additional 22% greater air flow.
With that additional air flow Mishimoto claims to get
an additional 40 foot pounds of torque
with no additional supporting mods.
Mishimoto gains this by providing a larger intercooler
and larger mandrel bent tubing to provide
unrestricted airflow all while making sure
that air flow stays cool.
Since turbos operate off your exhaust gas,
this causes your intake temperatures to increase,
hurting your performance.
So with a cold air intake upgrading your intercooler,
paired with a tuner you can unlock the full potential
of the new airflow and the preloaded tunes
on your programmer.
Plus, if you don't want to use a preloaded tune
you can always use a dyno shop and create a custom tune
to load onto your tuner.
Bully Dog, Edge and SCT are all tuners
that support custom built tunes.
All right, guys, I'm gonna show you a little bit
why an intercooler is actually gonna be beneficial.
I figured I could give you guys a good visual
of what's going on in the engine bay
for this 6.7 Powerstroke.
So we're going to have air in with this cold air intake
here to the, it's going to lead to the turbo setup
which is in the back here.
The turbo is going to be spun by your exhaust
which is that's how it's sucking the cold air in
and it is going to send it to the intercooler
which is here, which is a water intercooler.
So it's cool to be a coolant, and then it is going to send
the cold air into the upper intake.
Now, since this turbo is wedged way in the back here
we do have a turbo that was laying around in the shop here.
Now this is a lot smaller
than what belongs on this Powerstroke,
but just for a visual reference here
as to why you need to have an upgraded intercooler.
So your exhaust gases go in here
which is gonna spin a turbine on the inside here.
So as your exhaust goes in, it is gonna spin
this little turbine and come out on the bottom here.
That turbine is attached to this side of the turbine here
where it is gonna suck cold air in and then force it out.
So with having your exhaust gas and your your hot side here,
it's going to heat up that intake temperatures
coming into the truck.
So that's why when you send the air out,
we'll send it out into the intercooler
have it cooled and force it back into the engine.
So that's why when you upgrade an intercooler
you get such an increase increase in power
because of the cold air intake coming in the engine.
(transition whooshes) Thanks for watching, guys.
That's about all I have left for you today.
