Making my Supra Sound Like an F1 Race Car

[@2008Mclaren]

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.

[@justinmanse2849]

isnt that what they did in nascar as well to get that iconic sound

[@jonb-h2z]

A old hotrodder trick is paint the headers towards the collector and run it. Where the paint stops burning off is where you need to cut the collector, it's the optimal length.

[@lowerd1]

Didn’t know that, pretty cool to know.

[@nikkwaus]

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

[@grant-nagy]

@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.

[@T3naci0usT]

@divinemedia Mike you are killing it with the edits dude! I really like the editing in this video! Also love the deep dive into the 4 rotor.

[@will96317]

I'm sure you've probably already asked James Deane, but his setup is THE 787 tone, I was almost positive he'd help you out

[@j.d.8593]

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.

[@unheimliche9410]

@@j.d.8593 kiwis do it best

[@Robvdk69]

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

[@shady_77]

the secret is stepped headers and equal length to get a high pitch sound from basically any engine

[@emi9643]

[@eliasbergstrom5300]

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!

[@lr7974]

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.

[@mylekdesigns]

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!

[@HEXAN-SC]

F1 sounding four rotor Supra?! Hell yea, cannot wait

[@Turntablist_Mk2]

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.

[@the900bot]

This video is awesome from a gear head perspective, changing the intake length and then seeing the difference on dyno is beautiful work.

[@BigTtheItalian]

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.

[@maxxrelax88]

the width of the pipe on the headers makes a massive difference to pitch, small diameter start and go stepped all the way to the end it will sound amazing!

[@FranciscoSantos-kp61]

There was a car racing at the European Hill-Climb Championship that ran a Judd V8 engine and it sounded like an F1 car (Georg Plasa BMW 134 Judd). On recent years there was a Mercedes SLK (Reto Meisel SLK340) running the same engine that's not even close to how Plasa's BMW sounded like. I was told the difference between the cars is simply the exhaust manifold. I don't know what's different, but apparently the high pitch will definitely be achieved on that specific component.

[@exige7227]

You made it sound more like an F1 car than the 787B but I am not complaining. Sounds epic!

[@chrisreardon7185]

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

[@eliasbergstrom5300]

Must be Maisteer you're thinking about. His videos are great and Adam shoul definitely take a look at them.

[@tdlaustralia7791]

This is a great style of video. Love the detail. It's definitely higher pitched. Not quite the scream of a 787b but on the right path.

[@justin3131ify]

Also FYI when trying to achieve equal length, be it intake runner's or headers use pingpong balls/ golf balls for measuring

[@technology42069]

Stepped down diameters so that the pulses reflect back against the step is what gives that sound. also a long merge can also improve the sound.

[@luccasrodrigues8253]

Stepped headers and equal length, you dont need anything else

[@the1satsuma1project]

I remember seeing a video which spoke about how the angle the runners merge into the collector make a big difference as well as a stepped header. That was on a v12 but I assume same principle applies.

[@josephmatuszak3855]

Not just runner length, but collector type (4-2-1, 4-1, etc), material and thickness, and fuel and timing can greatly alter the "pitch and tone" of an engine.

It's all over the internet, I mean just google how to make exhaust sound like F1, why re-invent the wheel just look up what to do. Stepped headers, w equal length and straight pipe, is the trick btw that muffler is ruining the potential of the sound this thing could have

[@MrNotStock]

It's not velocity, its port resonance. Pressure waves peak and push more air into the cylinder just as the valve closes. Example is when you see fuel coming out of the intake or out of a carburetor at full throttle. The pressure waves flowing backwards cause that effect.

There are a few pictures for reference of their engine floating around with the exhaust and the intake trumpets that look vacuum actuated for length to adjust the sound and airflow. Maybe make an engine test stand for the 4 rotor and make a few designs to try it out.

within the past few days I saw a video explaining sounds of a 3 rotor and why it sounds high or low. He was looking for the low and found out that on rotories like that they have the middle header come out 2/3s the length or something like that. He said it was the same difference as the 7th threat or as he said a power cord. He said each pipe is a different note and playing with the lengths in the since of how music works can allow for the diffrence in sound. Im prob talking way over my head but this video and that related in my mind.

From what I’ve read to get the high pitch scream, you’ll want to reduce the diameter of the headers. Then step the tube diameter up. So 2” to 2.25”.
