what's up everybody its Justin and we're
bringing you another dyno session with
my 2017 Subaru BRZ this one is the
follow-up video to my stock BRZ power
numbers which i've posted a little while
back we now have the upgrades on the car
we now have the tuning done on the car
so we're getting ready to get the power
numbers and see just what kind of gains
the car got from adding these upgrades
so we're going to break out from the
dyno shop take a look at the results and
then we'll throw in another pull from
the dyno towards the end of the video
here just because we love to hear the
car screaming at fourth gear full throttle
alright everybody we're back from the
dyno with my 2017 Subaru BRZ after the
modifications have been done so just to
go over again what the upgrades are on
the car we have the stock airbox with
the drop in filter from Blitz the Perrin
Inlet tube that covers the intake side
of the engine on the exhaust side we
have the Revworks unequal length header
the Perrin over pipe the Berk front pipe
with the high flow cat and then
the Tanabe concept G exhaust finishing
things out for the bolt ons for the
engine tuning we have the ECUtek
custom tune we went through about 14 or
15 different map revisions to get to
where we are today so that's what we did
the power numbers on on today's dyno of
those bolt ons and that tuning so what
we're going to do is a little bit of
data analysis on the dyno graphs and the
results from this dyno session so I have
to admit I'm a little bit upset with the
peak numbers of the car from a horse
power and torque perspective the 2017
BRZ did not make any more power than my
old FRS did from a peak power standpoint
so if we look at the graphs see my FRS
made 182 horsepower peak that was the
maximum that it made and 149 pound-feet
of torque at a maximum the BRZ the 2017
BRZ with virtually the same
modifications it also made 182 peak
horsepower and it made 147 foot-pounds
of torque or pound-feet of torque so a
couple less on the torque from a peak
standpoint but also keep in mind these
are completely different times of the
year I shot the FRS dyno in February so
the ambient temperatures I remember is
pretty cold that day it was snowing the
day before so that could have an effect
the ambient temperatures today for the
Subaru BRZ it was about 60 degrees and
sunny so a little bit warmer so that
definitely has an effect on the dyno numbers
alright so peak power numbers aside
we'll talk stock BRZ versus tuned and
upgraded BRZ now even in that case the
BRZ and stock form made pretty good
power made what did it make 144 pounds
feet of torque and 179 horsepower and
with the bolt-on's and the tuning we made
three more pound feet of torque at 147
and three more horsepower at 182 so the
peak numbers were not significantly
greater over the stock BRZ the FRS in
contrast made a little bit less from a
stock standpoint so the stock FRS my
old orange car it gained more from
the bolt ons and the tuning than the BRZ
did so it seems like the BRZ might be a
little bit more efficient with the newer
engine changes and the exhaust and
intake changes that it has done to it on
the stock car so it makes more power
from a stock standpoint it just won't
gain as much when you put the bolt ons
at least in this particular one-off test
that I did now comparing the dyno graph
from the stock BRZ to the tuned BRZ
that's where we really find the meat of
the data so peak numbers only tell one
part of the story the most important
part is where are we making more power
in the torque and in the horsepower
curves and on these cars we have a
torque tip in the mid-range and the low
torque in the low rpm ranges and that's
where the tuning and the bolt ons make
the most difference on these cars so
looking at the graphs you actually see
the real data and what's really going on
from a power standpoint so there's huge
gaps or huge leaps in power in the
middle rpm range especially from around
3,500 rpms up to oh I don't know 52 or
53 hundred rpms are significant power
increases found there and while it
doesn't affect the peak power that is
all of the changes that you feel in the
car driving
that's why the 2017 my opinion feels so
much quicker than the previous cars and
some of that is the gearing too of
course but all of that power you gain in
that mid-range is what you're feeling
and where most of the performance is
gained one other thing I noticed with
the BRZ is it kept increasing its torque
curve as you go up through the rev range
versus kind of plateauing and just being
flat it continued to grow from about
4,500 rpms or so maybe 5,000 rpms the
torque curve steadily increased all the
way up which is good of course we want
to see power increasing throughout the
rev range preferably to redline but
that doesn't always work out that way
so in reality after we look at these
graphs we can kind of see that maximum
power wasn't necessarily the three
horsepower and three torque on the peak
then we're seeing upwards of you know
almost 15 horsepower about 15 and torque
and 13 or so horsepower 14 horsepower so
there are some big gains there in those
big sections where the car was making
little power in the mid range in the
upper middle range so for me when I look
at a dyno graph that's really what I'm
looking at is where are we making those
big gains not just on peak power it's
where are we making those change over
the stock graph so from that standpoint
I'm pretty satisfied it's actually very
similar to my FRS in the way the gains
were had the gains were in the similar
areas compared to the FRS and the BRZ
now if we look at the dyno graph from
both the tuned BRZ and the tuned FRS
they are pretty close to identical so
Subaru and Toyota they did a good job of
making sure these engines were
consistent you know from the generations
of years at least you know from my data
that I've got and while the power is
made in different parts of the torque
curve on the 2017 it looks like almost
the power comes on a little bit sooner
in some areas and a little bit later in
others but the 2017 car has a pretty
similar almost exact power curve and
torque curve that's a 2013 FRS did
alright so I think that covers
everything Cliff's Notes peak power
numbers were not that impressive 3
horsepower and 3 pound feet of torque
over the stock BRZ
but the important areas in the mid-range
all of that our the torque gained
underneath the curve was pretty good
there and most importantly out of all of
this the car feels a whole lot better
than it did stock from a power delivery
standpoint the 2017 car for sure feels
quicker than my 2013 FRS especially in
the low and mid range and again I think
a lot of that is attributed to the
gearing changes and it's clear that
these cars can make power in the same
areas that the older generation cars did
it does seem that the newer cars are a
little more efficient from the factory
so in the stock configuration stock
airbox stock header stock exhaust all of
that stuff is pretty efficient compared
to the previous generation cars so I
think that's going to do it for this
video I hope you all enjoyed I hope it
was informational and stay tuned for the
next test I'm going to throw the Grimmspeed intake
back on the car and see if
we get more power just by changing out
that part in fact now I'm actually
really excited to get that test done
being that the peak numbers were what
they were with the current configuration
so we'll see if that grimmspeed intake
makes even more of a difference on the
peak power numbers so we have more

would love to hear from you thanks again
everybody for watching we will talk to
you all next time
