STEP THE HEADERS.. Smallest diameter first than increase diameter by half of an inch every 12 inches until you have three different diameters. Will sound like a biblically accurate angel singing.
@Maisteer has a video called "how F1 Sound is made" he talks about how stepped headers change the sound. I think it's a solid video, he also mentioned equal length headers and equally spaced firing order.
i looked up the frequency on the cars and also from your 4 rotor. so what you can see from the frequency/hz is that the short intake come closed by the mazda 787b but i also see in the graphs that your car has 4 clear peaks while mad mike and the 787b only have 3 peaks. these are guidelines the distance microphone environment can make a difference time stamp, cars, frequency (hz) 00:47 mazda 787b 651 and 1307 and 1945hz 00:55 mad mike 540 and 1090 and 1141hz 01:07 old toyota 509 and 768 and 1022 and 1280hz 29:49 new toyota 529 and 791 and 1053 and 1317hz 10:10 dyno run short 627 and 935 and 1243 and 1556hz
respect for doing the reasearch but surely this wont be correct as for the 787 and mad mikes audio it was recorded on a different set up to what mike uses meaning the audio could be edited, and the frequency would be different on all clips because of the different mics they use
@@trojanz-_-2483 yes indeed that is way i say there can be a difrence also rpm is a big thing the masuring is of hearing when the car is in high rpm, but you have guidelines. the graph are real nice to see the difrence of peaks of the sound my own car is 130 and 250 hz my old honda has 300 and 500hz.
@@dubstepismtlife it took me a while longer since i’m going to school and working two jobs I could have definitely finished faster if i had the cash up front but i could only fly once a week maybe 2 times a week and miss a few weeks so it prob cost me around 15-20k but if you have enough it could be cheaper/faster just depends on your rental rates instructor rates and all that
Yes, but also placement of the steps and the collector in relation to the exhaust ports, pipe diameter before and after the step, and surely some other factors I’m not even aware of. It’s not as simple as “ make it equal length and stepped.”
Also i believe the dip in power is caused by a transition of the air going from turbulent to laminar flow at certain air intake speeds. look up bernoullis principle. The variable runners probably also help with this dip.
Stepped headers are one of the largest contributors to the sound, also improves the scavenging as well. If you can do a progressively expanding exhaust on top of this it will add to both the sound and scavenging. Another factor to think about is the material you are using for the exhaust and headers. This has a massive impact on exhaust note. Materials like titanium; while overkill for your application, are one of the main reasons the f1 engines scream the way they do because it resonates at a much higher frequency. If you can find exhaust pipe made with 440C Stainless Steel (or any really hard, high tensile stainless steel), that would be your best most cost effective option when paired with stepped headers, and a progressive header-back pipe. Edit: Give 409 Stainless Steel a shot. There are already off the shelf exhaust tubing made from it!
The biggest part is actually the merge angle of the collector. I could build a stepped header, with perfect pulse timing at the collector, but if the merge angle is not right, it will not scream.
@ It’s a combination of stepped headers help for sure, but there’s so much more to it. What many also fail to realise is, that a lot of the sound starts at the intake. Listen to the induction noise of a Ferrari 812 for example. A lot of the sound coming out of the exhaust is that sound amplified and transmitted through the whole system. There is a reason why Mustang GT350R will never sound like a 458, and the intake is the main reason. Ferrari is an absolute league in its own when it comes to impulse tuned intake design.
@@djremotion2 Yeah I wasn't going to even mention inconel 😂 A full length exhaust would probably break the $30k mark in material cost alone. Either way titanium is better for that high pitch sound, it resonates at a higher frequency, and its lighter. Inconel is really only useful for extreme heat applications.
A Maisteer stepped header experiment collab on this would've gone down in history as the most unique sounding 4 rotor ever! But would be a video series rather than an episode, as the 2 perfectionists meet lol. Also, there was a guy in NZ that made the slide throttles. Have to try find it again or Logan has experience with that too.
Did you miss the part where Adam said "they won't share with us their header design unless we bought a complete engine", James has a PPRE engine, and i'm sure that comment from Adam was pointed at them (PPRE, not James) and some others.
Ppre has designed a engine and exhaust system that work together . They have lost of money in research and development over decades so it makes sense to protect it. So just coping a design from a different engine builder won't achieve the same results . If he wanted a turn key package that sounds like the 787b he should have brought a package from them

@@emi9643 ignore him bro, guy is being a nob. your punctuation was fine. he's just a butthurt lil twat thats going on all the comments calling people nerds
I have designed a "variable runner" system like the "telescopic" 787B system, and it's actually easier than it seems to create. The only thing you have to decide between is whether or not you want the stepper-motor variant or the linear actuator variant. Stepper-motor variant is easier to work with and more accurate control, but LinAct is faster and cheaper to get done but you lose the variability of the stepper-motor (basically you get stuck with min or max unless you want to get expensive LinAct's with variable range based on voltage applied, which in turn requires way more finnicky work to get the right unless you have it tied to a MAP-sensor and have a table that does actuation based on a pressure-table). There is a third method that's proprietary, which involves patented stuff with some rotating parts that also varies turbulence spots throughout the runner using the same science people claim they're doing when you see those spiral velocity stacks in use. Easiest solution for Adam might be to get the system off of a Yamaha R1 that moves stacked funnels. Way easier to deal with for when it comes to airfilters and could in theory be straight retrofitted using R1 parts.
Hi what stage at you at with your design is it prototyped yet? Have you created any content around it, i see your channel is blank so perhaps somewhere else? Thanks
Absolutely love the technical videos to learn new things and just learning about the amount of engineering that goes in behind the scenes to get the best possible performance!
Maisteer has a couple videos exploring different techniques to get that high pitched sound. The major part is having expansion chambers (going from smaller tubes into bigger tubes creating a step) in each header tube. Definitely check them out Adam!
Having a 13b semi-p fd myself i can comfortably say that the brap sound you are looking for comes from porting mainly. Meaning if you have your engine semi/full bridgeported or semi/full peripheral you will get that brap. I was looking for the weird hiccup between braps and my tuner told me that it happens when the ecu tries to correct the mixture. If everything it tuned properly then the braps should be crisp and clear. Thats as far as i know but there might be stuff that im missing.. hope it helped a little :)
hi adam look into stepping the runners say having half the runner closer to the collector be 2” ID and the other half 2” OD, could do a larger step too but that’s an example there was this guy doing alot of digging over a few years trying to find out how a certain 2 years of f1 had a distinct howl and it came down to the runners being stepped
I can say without a doubt I absolutely love the sound of your four rotor with the new exhaust and I would have to say I actually prefer it over some of the other ones I've heard so be proud
I REALLY liked this video and its format. If this is any indication of what’s to come this year, then I think we’re in for some great content. Nice work!
It would probably be easier to use an upper and lower intake manifold with an IMRC(intake manifold runner controller). You can have 2 sizes of intake runner and use butterfly valves controlled by the IMRC to swap between them. Ford 2.5L Duratech motors had a really cool system.
Dude I haven’t watched an AdamLZ video in years but watching this felt no different than when it was just him and bmw with a BMX bike. I really appreciate the mature but fun content. No absurdity, just having fun and building crazy stuff. Go Adam! Excited to see what the future holds

@NitroNuggetTV nah they're not, it's basic physics, we know how to make the sound for more than 70 years now, people are just lazy when it comes to researching shit.
@ Well, I've seen first hand when the theory doesn't align with the result. Its very easy to say people are just lazy over the internet, but that's not the case when people have invested huge amounts of effort, time and money into something, abiding by all the research and rules, only for it to fail. With exhausts, the "black art" is the huge amount of variables you're having to work around, paired with a lack of specialist hardware/software available, and those issues aren't simply resolved with EL and stepped runners + researching sh-t, as you boldly proclaim in your comments.
@@NitroNuggetTVI have over 13 years of experience building headers, and I live in a third-world country. You can't tell me anything about how to build headers, especially on a tight budget. If your exhaust sounds terrible, it's because you built it poorly. Inanimate objects don't have free will, and there's no "black magic" involved-science is science, and it's replicable. You can complain all you want about how your poorly designed headers sound bad because "fate" or "God" made it so, but the reality is this: it's entirely your fault.
According to all of the research I've ever done, equal length STEPPED headers is what results in that high pitched, bell-like exhaust tone. Maybe try 1/3-1/2" steps every 10-12" inches
I heard a few times, the secret to F1 sounding exhausts is to have the exhaust tubes get progressively bigger in diameter from the head to the collector, possibly the even the whole length of the exhaust. Your exhaust is certainly sounding a lot nicer now
I shot media at the Polecat event and hearing the 4 rotor scream through the hills is the most insane thing I've ever heard, and I had just seen the space x rocket launch before the event.
Now that's a real driver, unlike some other content creators doing so much engine upgrade just for show but doesn't drive like Adam LZ. You know those people are.
F1 engine header pipes has a increase in diameter right before they are united in one pipe. It because there is a advanced when you have it in high rpm engines. One consequence of this header format is the well known F1 sound.
STEP THE HEADERS.. Smallest diameter first than increase diameter by half of an inch every 12 inches until you have three different diameters. Will sound like a biblically accurate angel singing.
isnt that what they did in nascar as well to get that iconic sound

Johan is really stepping his game up over the past 5 years. Always willing to learn and knows that with the right tools he can build anything.

Probably sound waves reversing back down the pipe rather than out the end and colliding possibly also affecting the valve opening capability/action.

On an LS, the firing order changes the sound in an 8-1 header and in a 4-2-1 header. They need to go in to the collector the same as the firing order.
Sequential firing order right?
That drifting at the end was 🔥🔥🔥🔥
Best video in a while, love these deep dives going in to the theory behind why things work
Lov the production and tech content in this vid 👍
First vid I've caught of yours. Love the laidback vibe of everyone.
Really enjoyed this video format 👍
According to all of the research I've ever done, equal length STEPPED headers is what results in that high pitched, bell-like exhaust tone. Maybe try 1/3-1/2" steps every 10-12" inches
I love the engineering side of this so much, just makes you want to constantly keep build an manufacturing badass stuff!!
Keep the Johan videos coming. Just love watching him work through a problem and turn it into metal.
When Adam said that hes going to focus more on YT quality this year, he really meant it 🔥🔥🔥
What a work of art. I would give anything for my b18 delsol to sound like that. Much respect!
That Shipstation ad was hilarious. idk why but the whole reverse skit had me rolling, killer marketing man!
I heard a few times, the secret to F1 sounding exhausts is to have the exhaust tubes get progressively bigger in diameter from the head to the collector, possibly the even the whole length of the exhaust. Your exhaust is certainly sounding a lot nicer now
So many t shirt / poster photo opportunities on last run.
Excellent work Johan, and Mike - editing and music were on point.
Mike we love you and the videos just keep getting better and better 💪🏻
I think this might be the coolest build you've had on your channel, and definitely top 10 on the internet
Crazy thought Adam’s Supra against DDE F12😂🤯
from BMX to BIG BOI Stuff and i love every second of it. keep killin it dude.
You must have a ⛽️ station at home 🏠 and those flames 🔥 start wild fires 🔥
I shot media at the Polecat event and hearing the 4 rotor scream through the hills is the most insane thing I've ever heard, and I had just seen the space x rocket launch before the event.
You need to get out more.
The ending was so sick
yo
🇺🇸🇺🇸
Very well shot and put together video! Nice near reverse entry at the end.
I definitely understand chasing that specific sound but even the way it is it sounds incredible!
The 4rotor Supra has to be my favorite of Adams. Such a sick build
No matter what it sounds like, it’s an Insanely good sound, and a killer build!
Now that's a real driver, unlike some other content creators doing so much engine upgrade just for show but doesn't drive like Adam LZ. You know those people are.
DUDE.....this is the next level parts development LZMFG should be focusing on!! Demystifying the unicorns and making it functional for everyone.
Please do a collaboration with OJ at Fluid Motor Union!
Absolutely love the engineering aspect of this video.
Such a cool vid and the clip at the end is soo cleann
F1 engine header pipes has a increase in diameter right before they are united in one pipe. It because there is a advanced when you have it in high rpm engines. One consequence of this header format is the well known F1 sound.
You made it sound more like an F1 car than the 787B but I am not complaining. Sounds epic!
we are truly in the future, love to see the CAD / CAM design going straight into manufacturing, its great
These are the killer LZ videos we have been missing! 👏
