hey everybody my name is Justin welcome back to our Pit Lane garage today we're
going to be bringing you a couple changes to the BRZ in preparation for
our ACE A3-50 header install will show you what parts we're swapping out and
why let's go ahead and get started
so what are we doing today to the car again this is preparation for the ACE header installation this is kind of a best
practices to get the most performance out of the ACE header and the Delicious
tune so we're putting some of the stock parts back on the car because they are
proven to be more reliable and better performing than some of the
aftermarket counterparts that I have on there OR they may just be the preferred
part that the tuner likes to use in the case of the intake we're going to be
putting the stock intake back on this is our standard whoops our standard stock
airbox it does have that Blitz high flow filter installed into it just the
drop-in filter the big thing with the stock airbox is you retain the stock MAF
sensor location so airflow readings are per a stock car I also have the new
updated Perrin inlet tube for the 2017 version of the car you might have
remembered in previous months I had the Perrin inlet tube from my 2013 FRS on my
2017 car and while it fits it's not exactly perfect this 2017 version is
revised specifically for the newer cars and will fit a little bit better so the
first change is the stock airbox with the Perrin inlet tube and the second
thing we'll be putting back on is actually the stock crank pulley as
opposed to the lightweight Perrin pulley now after talking this over with the
guys at CounterSpace Garage and getting their support and knowledge to back
this up we were able to find some data out there that proved that the stock
pulley makes a little bit better power in the mid-range and the peak I believe
will try to find the graphs with that that you have to compare with
so the preference there was again to have the stock part on versus the
lightweight part so we're gonna pop the hood on the car start getting the old
parts off and then of course we'll go ahead and install the new parts back on
the car I do have to get my current ECUtek tune
revised since I'm putting the stock airbox back on and kind of the whole
goal of putting these parts on right now before the ACE header is I'm going to
take this specific setup with my current unequal length Revworks header back to
the dyno kind of get a baseline dyno of where the car sits now before we throw
the ACE header on so when we do the ACE header installation we'll basically
be comparing that plus the Delicious tune against my current car setup with
the Revworks unequal length header and my HRI tune
so there we go the old parts are off or I guess the upgraded parts are off this is
weird going back to stock but it just goes to show how efficient and effective
some of the stock parts are especially on the newer 2017 cars no troubles
getting the crank pulley bolt loosened up the green Dino saved my knuckles from
getting smashed I also used a little bit different technique this time you might
have saw in the video I threw the end of my jack on to the
breaker bar for a little more leverage and this actually made getting that bolt
off of the crank pulley loosened quite a bit easier so I'm gonna go ahead and
clean up the parts on the table here obviously our Perrin crank pulley is off
our Grimmspeed intake is off I do have to move that MAF sensor from that pipe
into the stock air box which is right there in the stock location and then
we'll get the stock crank pulley put back on followed by that air box
so a quick wardrobe change followed by a gym session and we now have the car back
together everything went smoothly and as planned our stock pulley is installed
once again down there nothing fancy the new 2017 Perrin inlet tube went in without
a hitch except for one thing Perrin gave me a hose clamps for the throttle body
and for the intake box that were too small I had to reuse some hose clamps
that I had in the garage here and this is kind of annoying because I waited
four months for this Perrin inlet tube specific to the 2017 cars that got
delayed once because of QA issues and now I get the wrong size hose clamps not
a huge deal but was hoping for a little better from Perrin after that long wait
and of course stock airbox with the Blitz filter inside
so we are now one step closer to getting that ACE header installed on the car I
do have to take the car out on the street get an ECUtek datalog and send
that into my tuner just to make sure the car is safe because when we change out
the stock airbox from the Grimmspeed airbox we do have a change in the air
sensor reading in the computer so we want to make sure that is done and the
car is safe to go on the dyno but with this we'll be able to go take
it to the dyno have a good solid baseline to work from before we install
the ACE header and get the Delicious tune put on the car so stay tuned for
the installation video coming up next we'll do that put the Delicious base
tune on the car I already have that tune file we got to do a few different pulls
out on the street to get the tune calibrated for the car that will drive
it for a week or so and then get it out on the dyno but we'll bring a video of
the installation process and the initial tuning I want to give you guys some more
details and insight on how the ECUtek tuning and data logging process works at
least from the consumer point of view so we'll do that as well when we get the
next video out let's wrap it up guys if you have any thoughts or comments
questions or concerns leave them down below like always I love to hear from
you stay tuned we've got some more good stuff coming up real soon I might even
have one more surprise up my sleeve for the BRZ during this winter season
upgrade and don't forget stay fast out there everybody I'm checking out
we'll talk to you all next time
