The horsepower to noise ratio is pure gospel.
Full band got killed
Nice to see someone else into the quiet aftermarket setup.
1000hp = aloud to be loud
Highly recommend killing the fake engine noise - the dealer can do it or you can pull a wire, easy to look up. As a fellow owner of one of the 500 2022 BRZs in Australia, it makes a huge difference and sounds way better under load! No idea why they thought it would be a good idea to add it in the first place.
Cos it's music to the ears without upgrading exhaust?
@@Playboyer670 If you are fooled by a cheap speaker trying to trick your sensibilities so be it. It's not a "toy car", it does not need to sound like one either.
@@Ilost11 some people might actually enjoy. What's the big deal? I disconnected mine the first day because I already had an exhaust ready to put in. I thought it was neat and I can see someone liking it. Even some Teslas have fake engine noise.
@@Ilost11 you put loud exhaust you think you have a "race car"?
@@Playboyer670 I have never suggested I want a "race car" and that an aftermarket exhaust would somehow change that. If anything, your defense and praise of cheap simulated engine sounds make me believe you're the boy who wants his big, red "race car". I could care less what Tesla does with their cars. Any electric car manufacturer trying to emulate internal combustion engine sounds with speakers is deeply humiliating and absurd.
Its nice to see the infotainment screen in the right place and not emulating an ipad strapped to the windscreen! I hope more new cars do that… Great stuff Andrew! 👍👍
Finally someone fitted equal length header on this car..
9:10 the noise to performance ratio rings so true 😆.
I've played with a bunch of exhaust setups on my gen one but ultimately settled on a near identical setup, just with the stock catback.
Proves just how good the engineers designed the stock parts…
accept for epoxy getting In pickup
Averaged power difference over 500rpm steps from 5000 to 7000 rpm and came up with an average 4.5% increase.. Take the 4th root and that comes out as 0.15 seconds improvement over the 400m. Not bad.
Some people prefer to be obnoxiously loud, but i don't care about gaining noise in the exhaust if it does not gain significant power.
Great gains for an NA 4 cly bolt on with no tune! I would unplug that shift warning sound immediately haha
It can be turned off in the settings.
How come no one can actually provide any acceleration figures compared to stock with these headers and tunes around the world?
Nice! Honestly it sounds really good. Also, I agree 100% with what you said - if it's a 1000hp car, it's allowed to be LOUD. If it's 200hp, it's not allowed to be loud.
Excuse me, its 228 ok?
😂
@@JV8901 Touché! Haha 😉
In America they where getting an extra 10 hp, is that due to company tuning for the Australian models?
What would be interesting, would be to see if the ECU pulls power after a period of running.
Naturally aspirated, so unlikely. No performance drop at the track over multiple laps
Like an IOS update ? 😅
@@krispykruzer 😂
Would be cool if shops started to dabble in NA FA24's similar to the NA Honda K series scene since they are now making similar NA power. In my neck of the woods boosted cars especially with power mods are only good for a few laps before they get too hot.
FWIW most Honda’s are making more power to the ground because of the lower drivetrain loss, even if the bhp is similar. I want to see what hotter cams will do to these cars honestly
that shift beep at high rpm would drive me insane, first thing i would remove. nice video though 🙂
You can adjust via a few button presses, no big deal
It's a shift beep. You can toggle on and off and select and rpm you like. It's great as you don't need to pay attention to the RPM and just listen to the sound and then change gears.
same sound the GD STI's used, its a classic m8.
High flow catted front pipe please!
Based on the dyno, catback exhaust has power loss despite of people saying that there’s no effect.
So what you're telling me is that you could probably get 250 horsepower at the crank with a tune, intake, and better flowing catted-headers. Car seems to be everything I wish I had in my E46 330Ci. LSD, 7500 RPM redline, less weight, more focused and bolstered seating.
Lots of these cars dyno around 215hp which puts them at send 250hp crank stock :)
The e46 is heavier by 200/300kg, less rigid, have less track capability and slower
Pretty flash looking system.
Nice gains for pure bolt ons, any thoughts on going a shorter final drive?
They only go 140mph as it is. Car needs 100whp more not different gearing
@@andrewrossnagel9433 spoken like a true warrior of the keyboard.
@@shadowprice8100 Lol I have been to over 70 track days this year. What about you? lol
@@andrewrossnagel9433 let him be lol if he wants to top out at 100mph and he think its fast lmao
@@andrewrossnagel9433 I own a highly modified FD Rx7, have had it for 13 years xD, I find it hilarious that people continuously rag on the 86 platforms for being lacking in power yet I've owned and enjoyed everything they've wanted from a rwd platform for my entire adult life.
Thanks for your review and information.
You disable the catalytic converter from the header.
How do you overcome a check engine light that is on?
I mean between the two sensors there is no more catalytic converter
The fitting that holds the second 02sensor stops it
@@MotiveVideo
If I understood you correctly, no tuning is needed and the check engine light does not come on.
Yes ?
@@itaybutavia1204he probably use Defouler
Does this car have aftermarket intake as well?
Did this throw any check engine lights? I'd love to get 10% more power in the midrange and put on exhaust and headers but I don't want Check engine lights and have my dealer try to void my warranty
We said in video, no engine lights
Can yall ship the front pipe to the US?
As an Aussie, I'm very happy that the new model has extra power. Mostly because they are NOT legal for P-platers any more!
Should mean a lot less douche-canoes with pop & crackle tunes. Haha.
Why arent they legal? What state are you from? I'm from Vic and Golf Rs are legal and everyone on their Ps who has them has the pops and crackles 24/7.
Non turbo cars with crackle tunes lmao
I was only thinking about this the other day. What a great revelation. Much less stigma now hopefully.
Can’t wait to see this boosted. Is. True this car may come with the 3 cylinder turbo motor that comes in the Yaris GR or Corolla GR in America? That would be amazing package
So for an extra 10kws basically, you have to spend (guess estimate) another $5-6k on aftermarket headers and exhaust??
No where near that much for header and exhaust
what cause engine light on brz with hks header
I have a tear every time I see this car because in Europe it is not sold and if we want to import it in France where I live, in addition to all the import costs, we have to pay more than 20000€ of eco tax
I think you may be misinformed. Toyota sells GR86s in Europe. France probably has distribution, but if they don't many other EU states have official dealers selling them.
Great test. Please kill the fake engine noise. 😂
Facts😂
Id like to know since when having a quiet car is a sign of maturity?
Headers with a standard exhaust is when you will feel the difference.After market exhaust sometimes do add hp but usually decrease performance
How can horsepower be added but performance decreased?
@@jessekiks he probably means, you can add HP with exhaust mods. Some are designed for top end, but lose low to mid range performance. It is usually due to the change in exhaust scavenging effects. A tune is always recommended for the best gains
Enjoying this project 👍
Has this got the short shift gearbox or still standard?
Loving this build so far
Standard, but the shift is great and no need to change
@@MotiveVideo The videos of changing out the shifter make me nauseous and sad…so I agree that there’s no need to change it up. Feels good from factory. Ain’t broke don’t fix it. Thanks for putting out this content. Helps me understand directions of my build for this car. Thanks.
but how do u fix that torque dip?
Why had it taken soo long to crack the Ecu
Completely different ECU hardware/encryption.
So....
Please give us link buying this Header
Did you guys take out the airbox dental dam?
Australian cars don't have it, so no need to take it out.
@@MotiveVideo what is the function of that thing? Is this what's not on the Japanese versions (assuming the same as AUS) and why they are up 5hp from the US versions?
@@hyperbomb02 Some type of emissions thing for USA
@@hyperbomb02 It's to prevent unburned fuel from coming back out of the intake after the engine is shut down.
I thought UEL headers made more gains then equal length headers?
EL headers usually makes more power up high. UEL headers have been known to start spooling the turbo faster though. Not sure how much that matters given todays fast BB turbos.
@@NightPwnGaming What does it do n/a engines?
So 2/3 of the powerband has the peak TQ measure at a minuscule 93KW.
WTF?!
Interesting that he knows the cam and ignition timing, and also the fuel maps. Must be getting an early look in at the ecutek/motec stuff ;)
Ignition timing is shown over obd2, can timing would be subaru scan tool so not amazing
Have you got the link to buy the exhaust+headers? The last spec Is perfect
They’re not listed yet as these were prototype. Pop them an email though.
Needs a pair of 48IDA's out the bonnet
If they made them closer to 250/275hp standard then they would have been slightly more appealing
People said that about the fa20 too 'if they made them 20 to 30bhp more',people are never happy 😂
Can’t make them faster than the gr4cyl Supra tho
They do. Lots of stock GR86s and BRZs are dynoing at 210-215whp, which equates to around 245-250 crank hp. Toyota underrates them to avoid taking sales from the 255hp 2.0L Supra, which is much more expensive.
People will disagree but you're 100% right. Everyone agrees the biggest changes from old to new brz is power delivery. This car should be available with 350hp or 300whp from factory.
@@andrewrossnagel9433 If that's what you want, just get a Supra. The GR86/BRZ make more sense as pure lightweight NA sports cars. Same as why Honda didn't make a turbo S2000. They had the NSX for that market. 250hp is plenty for a car as light as the GR86/BRZ. 100hp per litre is nothing to complain about.
Sounds good😎
I thought you need a tune if you put bolt ons on boxer engines
Don't "NEED" it, but would be good.
there no design significance. it seems its just the initial catalyzer restricting it.
To bad you didn’t wrap the headers or have them coated in something like “White Lightning” which is a THICK ceramic coating (like 3mm) that acts similar to wrapping them to keep the heat where it belongs… I. The exhaust gases.
I highly doubt this engine would create enough heat to become an issue.
Exactly
Would matter if was turbo and 500hp, but it isn’t
@@MotiveVideo Reduces engine bay temps, which impacts how hot the intake pipes get, so not a terrible idea. Everything counts!
@@Blight-fp3vt this is my main thought. After having a turn car for almost two decades. Thermal control makes a huge impact on under hood temperatures.
Wrapping my turbos hot side, manifold and down pipe as well as making heat shielding to then go over it all took my under hood temps from losing my eye brows when I’d pop the hood to, not much heat In the face at all.
The high temps were even with normal driving so spirited driving….
good video. Can't wait for the tuning to come out. Any idea when we can see tunes? Taking ages. Heard Ecutek has made progress though.
Love the headers and exhaust also btw. Def like how it's not too loud. Sounds good.
Hopefully soon. We want to turbocharge it!
You lost a lot of weight good job mate
It looks like it made the torque dip worse.
what is the kink in the dyno graph at around 4500rpm?
factory tune
Gear change possibly
@@NZcarBlog nope
Love the na gains but turbo is the way!
No it's not, the ECU is locked...you can't turbo it.
Lol 'ecu is locked' doesnt mean it can't be tuned. The g8x M3/M4 has a locked ECU and its already been cracked. Just gotta wait for someone to unlock it
engine is so anemic still in this platform, the power bump from this gen compared to last was huge but its so disappointing to see that a full exhaust system only makes a 6hp gain over the stock configuration... even if the power is higher through out the band that is still pathetic compared to what older k series SI's can do with the same mods.
That just goes to show how optimized the new platform is compared to before. They left alot of performance on the table in the last gen. This time, not so much, so there is less to wring out.
While your down there, by any chance did u guys check any rtv in the oil pan lol 😅
We did. Watch previous video
I would bet the exact same gains would have been had by simply banging out and removing the oem cat inside the oem header.... and you keep the factory heat shield. Free mod
Feel free to test it and prove it.
@@MotiveVideo I have many times... just not with the specific header you used though... However the design looks very similar to most.
Explain how forced induction isn't possible yet, meanwhile HKS/ Trust have already made kits for these
ECU isn’t cracked (is close though) and MoTeC package not ready yet.
I wish they did unequal length headers instead. You don't get major power gains either way, so you might as well get the much better Subaru rumble sound. GR86s and BRZs with UEL headers sound amazing, and there's even a significant improvement with the stock exhaust.
MCM fitted a turbo kit to theirs
We know. We’re friends. But it was last generation which is tuneable, this isn’t yet.
the fake engine noise has to go, makes it sound like a goddamn vacuum. price per performance is not great with this package though, this whole system is incredibly expensive for 14hp and 15 decibles
Considering there is nothing else you can do to it to make power yet, it is worth it for the mid range increase and sound.
That peak and drop in the mid still gives my OCD the twitches. I’d be curious to see how it would go with unequal length headers, and if I’d smoothens out the funky looking midrange.
Need a tune to do that.
Should've gone to pulse racing!
How much does it cost for that whole exhaust package Andrew? 🤔
As per the video, the headers were a prototype...
@@sepg5084 Yeah prototypes cost money too, they don't magically appear.
@@MafiaboysWorld they usually dont cost anyone money except the manufacturer because its a prototype...
Thousands of dollars for duck all power.
While on paper that exhaust is "legal" it would still easily fail EPA standards which sucks.
As we said, depending on location.
You should do that first K swap on one.
Would make it illegal in Australia and can't be engineered, so then we couldn't sell it to LMCT+ to raffle.
This stock FA24 makes more power to the wheels than a stock K motor.
@@mrphuongie 😂
@@mrphuongie Yep. Those k series are great, but this new FA24 is proving to be more powerful than all of those wonderful Hondas when put on the dyno.
@@MotiveVideo is it legal to swap an engine in Australia?, In the UK anyone can swap an engine then notify the DVLA of the changes for the logbook with a piece of paper form a garage signing it off confirming the engine swap.
seriously? that noise called music need to stop, completely killed this video for someone that wants to hear the exhaust, thumb down
We can’t buy it in California
Highly recommend killing the music
Is it just me or is 200HP from this thing from factory so miserable?
Not sure if my expectations are so warped from the 1000hp cars we see often nowadays.
True but these cars don't weigh like 4500 pounds lol.
Horrible but still better than the 147hp from the first generation FA20 motors and you can actually feel the difference.
Not miserable imo. Lightweight and genuinely decent torque for the street. E85 and some bolt-ons will wake it up, forced induction will make it a pocket rocket.
Beyond that you just need a different platform if
@@harrybuhse8622 true. I had a 2016 scion FR-S with full bolt-ons, supercharger with big blower and e85 and holy it was such a blast. Now I own a GR86 and wow bone stock it literally felt more powerful than the FR-S when it had an intake, full exhaust and a stage2 tune. I currently have an HKS filter, carbon filter delete, grimmspeed intake tube, berk high flow catted frontpipe and a borla s-type catback. Can't wait to get a header, overpipe, tune and boost it. I'm loving this car so much.
everyone use to fang on about Mitsi evo's. 2nd and 3rd gen evos only made about 200hp at the wheels as well, the torque and short gearing made them feel quick though.
👍🤙
can’t stand how weak these cars are haha, sold my BRZ couple years ago and bought a 350z
I raced one in a 1' Rolla. he only gained about 3 lanes in less than a 1/4 mile. fucking slow ass car.
Needs a turbo
*Stabs people that say 'zed' instead of z*
pretty sure i know a guy that can unlock the ecu i helped him crack previous versions hit up the chief technical director Cosworth motorsports
sorry hes now senior development engineer
Plenty of different companies are working on it. None have fully succeeded yet.
🏁❤️🏁❤️🏁❤️🏁❤️🏁🏁❤️
Booo equal length header. Was really hoping you went unequal length so we could listen to what it sounds like. I'd sacrifice a bit of power for that boxer rumble any day.
That musc 🤢
Still sounds like crap lol you can't make it sound good without making it loud.
Your opinion differs from ours.
1000hp GT-R = allowed to be loud
200hp BRZ = not allowed to be loud
@@MotiveVideo you can say that all you want it doesn't make it sound good lol
I swear it's impossible to make these things decent. A used 350 with a overhaul is cheaper and faster. Toyota needs help
Put an autronic and a t51r on it and boost it up.
Stop fart assing around
