Mods welcome to another episode of
Mighty Car Mods proudly supported by
just car insurance now in our last
episode we tested a bunch of different
filters on some cars on a Dyno to see if
they make any difference to Performance
we've got a lot of comments from people
saying that if you want to see any real
difference up to 20% you need to install
a cold air intake now a cold air intake
no one on the internet can really agree
what it is but there's two definitions
that people can kind of agree on one of
them is a of tube or piping that's
getting some air from outside of the car
and feeding it into the filter and the
other one is actually relocating your
pod filter away from the engine down in
the bumper starts sucking in nice cold
air and apparently it can make up to 20%
extra power Martin that's right so today
we're going to try a bunch of different
setups to see if they can actually make
20% gain or any gain Martin any gain at
all I'll be impressed with 5% I'll be
impressed with seven okay done five and
seven if we get that we're going to say
everyone buy cold air intake done let's
check it out mad in our last episode we
ran pod filters on a variety of
different cars on the dyno so we could
see how they Stack Up Against The
Factory
airbox on our 1.3 l naturally aspirated
car we lost power with both pods and on
the turbo car we had no significant
gains so we're down at Port hacking
automotive and we're going to be running
an R34 Skyline on the dno to see if a
cold air intake makes any
difference this Mario Kart Edition R34
Skyline has a 2.5 L inline 6-cylinder
turbocharged engine and a catback
exhaust we're going to start off with
the factory airbox so we can get a
baseline of what kind of power the car
is
making the factory setup also includes a
snorkel which feeds cold air into the
airbox
[Music]
okay with a stock set up it's time for
our first
[Music]
run we've got 165.540
time to put on a pod and see what kind
of power we don't
[Music]
get we've got
[Music]
24° during the run the pod's coming off
and we're going to do a run with no
filter at all to see if there's any
restriction under the hood quickly heats
up to 34° but once the dino fan switched
on it comes all the way back down to 24
[Music]
again with no filter at all we've got
around the same figures as the factory
system proving that a clean filter is
not a restriction on this
setup we're doing another run to confirm
our results and we've got
168.5 Which is less than our Factory
airbox with the
snorkel what we're doing now is removing
the headlight if you ever been to the
drags you've probably seen that some
people remove the headlight on the side
of the car that has the filter uh this
is kind of like a cold air feed so with
this gone uh the industrial fan in front
of the dinno is going to be sending cold
air 15° ambient temperature straight
through this space into the filter we're
going to see if that cools the air down
going into the car and if that turns
into more
[Music]
power so that is about as cold as your
feed is going to get we're going to be
going directly through here into the pod
filter obviously this setup is not ideal
for the street driving around without a
light at night means you can't see the
zombies but it is going to give us an
idea if a direct feed of cold air
actually makes a difference to our
[Music]
power we've got
so it has had some effect on so it's
more steady it's getting the same air
temperature the whole way through that's
right so without the cold air feed the
air going into the Pod is heating up
over the Rev range whereas with the cold
air feed it's staying at a constant 25°
but this hasn't translated into more
power all right so the ambient
temperature out here is 15° the
temperature where the filter sits is 25
but the temperature after the turbo and
the intercooler is staying at around 42
no matter what's on the front of the car
we're putting a cover on the Pod to see
if it makes any
difference we've got
166.370
less than our Factory
airbox the results of all the runs we've
done so far with the different filter
setups have been almost exactly the same
and only a couple of kilowatt different
between each of them so it's time to try
something a bit more
extreme we're making a custom front
mounted pod filter so this really uh not
only represents the ultimate in cold air
intake but it also is like an umbilical
cord between car and owner there they
are look at that
Mommy
Mommy in this test the filter is nowhere
near the engine it's getting air
directly from the fan if we don't see
gains here then cold air intakes are
well and truly
busted we've made an extra 3 Kow but is
it repeatable
yes we've got a 3 Kow gain across the
Rev range it's not a lot but it is an
increase in
power okay so with the factory airbox
and a new filter we peaked it around 169
KW now with our custom front mounted pod
filter best case scenario we're getting
173 now we know from our last episode
pod filers mythbusted that you need a
10% gain in power for it to actually be
noticeable now with our differences
between the cold air intake and the
factory airbox Marty we are talking
about a measly
1.7% of an increase you're just never
going to feel it but it is an increase
and we've been able to see it repeatedly
on the dyno that if you change up this
setup you can actually make power and
every bit counts right yeah you know I
mean I guess if you're chasing dinno
numbers and you're up around 198 199 and
200 is your goal then putting something
like this in there probably you know
it's probably going to get you over the
line depending on what kind of car
you've got but in our test with our car
certainly I don't think it's worth it
that's right there are some other
considerations which are important if
you're putting a fter right down near
the bottom of your car and you likely
suck up water and hydraulic engine
you're making 0 Kow which for me kind of
ruins it and I guess you got to weigh
out the risk you know is it worth that
risk for making that 1.7% plus if you're
in New South Wales totally defect you're
kind of getting the attention that you
don't want for me unless you're making
serious power and someone can prove with
quantifiable evidence that it's power
that you're going to feel I'm not sold
on c a intakes Marty neither kab I'm
going to get a fuffle mad
[Music]
VI me go
