What song is playing at 26:50? It sounds so serene

i never really understood how wind instruments work or what parameters decide the frequency it'll produce despite watching videos on exactly that question,now tho after a vid focusing on a bad sounding V12 i 100% do.

I knew I got more horsepower after ripping off my front bumper

I suppose a sense of humour helps a lot when you are trying and constantly failing to achieve your objective! I admire the determination.

Thank you very much for watching... hope there can be a next one soon.

@@gregculverwell Certainly.... I'm failing my way to success ^_^

@@maisteer That's the way real life works.

Yeah, failing can be fun ^_^'

If you tell your friends it will...and thanks for watching ^_^

How bout you edit the word misstake, only seconds into clip and there's a mistake.

@@Rob-rp3cw no one cares get a job

@@bitchesihate oh, you can't see humour in misstake, poor you. Why bother replying? Get a better job.

@@Anvilshockwho ask?

In addition to my other comment, here's an alternative way to make 12-1 headers: ukposts.info/have/v-deo/jXSJimiPpIGZ26s.html&ab_channel=stainlessheaders

No one cares

Große Erwartungen. Ich drück die Daumen.

Yeah ^_^

@@maisteer i care

Hi Octav... glad you found the new video already. How was your drift season. Did the turbo V12 hold up?

@@maisteer Hey hey, don't underestimate my commitment, I actually managed to catch it Premiere. You really outdid yourself with this one. On my side, the S14 V12 Turbo build was constantly delayed every race by various factors human factors. Rollcage guy a few months, wiring guy etc. So I never got drive it yet, quite annoying. In an awesome turn of events, though, the first S13 V12 Turbo built here by one of our top tuners 11 years ago became available for sale. I wanted her since I first saw her so I worked out a deal and bought her at the final round. Makes 600whp 800wnm at 0.8 bar and 700/900 at 1 bar, internally stock M73B54. So I did get to drive a V12 Turbo Silvia, albeit only a few laps because I managed to put it into the wall slightly in quali. We suspect a number of technic issues led to that and while it looks dramatic, the damage was rather limited and fixed overnight. I have a video of the lap and crash on my channel if you want to check it out. There's a lot to say, might come back with detailed feedback but in short: Godly powerband, powertrain feels invinciple, I like the noise but it's mostly screaming big turbo, not V12, lighter than you'd think (1240kg 57/43) but still very front heavy and polar inertia is heavily affected. Having what is likely the biggest turbo in the paddock in front of a V12 makes it feel what I imagine a V16 feels like :) I also found it harder to "grab" the ground in search for grip compared to a smaller engine with less inertia and instant torque. Can drive around that, of course, but it is a characteristic. But it's unfair to judge the car only after 5 laps and before I get to put a good setup and geometry on it. It has tons of potential we hope to unleash next year. I'll be using it as my backup car but main it while the S14 is built to DMEC standards and get a different powertrain in it, no rushing. S13 scratches my V12 itch and feels like a great reliable practice car but the laggy polar inertia doesn't fit my style at all so will be moving away from V12 on the S14. Likely 2JGTE which is still heavy and long but fits the bill in other ways. Long rant, sorry, but that's why it took so long to reply, had to find a window.

I hope everything will work out in the end and that you can get the 2jz done without as many problems as the V12. Wish you a succesful offseason then and keep me posted. And that crash looked quite violent from the drone ^_^

@@maisteer Thanks a lot for you kind words, it'll be a fun offseason! It wasn't exactly a light crash but the damage was minimal, considering. I was fine, only things that hurt were my right knee and my ego :)

Hopefully the knee and the ego will be back to normal soon. ^_^

yes, that can be true. Can be its on the fidelity of the built. I know that,😂 couse HF=high fidelity. I testet that issue with my Model D and SH101 on the roof of my Lancia. It worked perfect! ✌

I didn't understand the loopback part fully yet from reading it, but I will look into it. I think I understand the concept of what you're trying to say and it sounds like a plausible and really good idea to check. Just as a note tough. The timing has to be spot on and that depends on the distance AND speed. And if we have different temperatures and/or pressures the pulse speed will be different between cylinders and then the timing will be off too, despite being equal distance. But just as a side note. There many things to get right at the same time, I believe.

@@maisteer Seems like my comment got auto-deleted. maybe because of the link?

@corri303 Yeah, links get auto-deleted. I can't even see them.

This would possibly be a great way to measure "exhaust frequency response". Never crossed my mind. But the speaker should have a proper air-tight adapter to fit the header inlet. Maybe also a closed enclosure. I'd probably use something like a 4-5" high power wide range speaker. In a perfect system one would have ten speakers behind a 10 channel DSP that is able to adjust delay in very small increments. That could be used to tune the header lengths. And measuring could be done one at a time or just as many as one wants. One could also make holes for additional mics, to measure the response in different parts of the system, though it could have little to no use, depending how the sound waves behave inside. I would really like to see someone try to test how the response curves from this kind of measurements would relate to actual output. I can imagine a way to sweep the actual engine and making a corresponding 3D graph of the exhaust frequency response. Think of a response graph, but add them one after another like one per 10-100rpm and show it a bit like a 3D fuel map.

Me neither.... so I got my friend Tim to help ^_^

@@maisteer Such a great thing to have a Tim!!

cute dog i like his smile...@@tptrsn

@@user-ye9py7ff1j Thank you, he was the BEST boy! :)

Everybody should have a Tim ^_^

Thanks. No academic here tough ^_^ But if you could tell your friends about the channel too, that would help a lot to keep making content faster ^_^

Simpletons may try to find other solutions, but the modeling has already been done... There are no secrets to it... you will never understand that trial and error engineering left us when computer modelling arrived...it just did!

Thank you very much for your support... But I need to to warn you! I'm gonna waste that money on exhaust piping ^_^

​@@maisteerthat's what I'm here for!

​@@maisteerain't that the point ?

Hmm make sense since f1 use Wet style fuel injector on top of the ITB. Pretty good idea

Can't blame the reddit people. Much worse were the people telling me that it sounds good at the event ^_^

Thank you Matias. Hope you tell your friends how much liked it, then it might not take so long to make the next one. Have a great day btw.

Thanks Cavedog, if you want to shorten the time it takes to make the next video, you could tell your friends about this one. I'm sure they will like it too.

Nah make the video as long as you need ain’t no one in a rush to catch a plane

Me neither.... and I don't want to wait again to make another video... If you would tell your friends about the video, that could really shorten the time it takes to make it.. But thanks for watching Austin

Yeah, do you have Gordon's number? ^_^'

I will... just for you. And every friend of yours you will tell about this channel ^_^

Thank you. But be warned I'm gonna waste all that money on pipes ^_^ Hope you can get M70 to sound right, tough. And I hope i can figure that out too by the next video ^_^'

It's less than a year old. You're still early ^_^

But some say I've spun a bearing ^_^

Thats awesome. Will you be posting videos of it?

I will :-) I can post a comment once I make the first part@@TheCluelessEnthusiast

@@martinoeldiablo2108 thats awesome brother. I cant wait

Me neither... keep us posted please ^_^

watch ksr build his 8-1 headers.. You'll be better off

me neither.... ^_^

Why schools don't teach like that then? Don't they care about full class participation? ^_^

"Also did the V12 car ever get on the dyno?" - not yet, Tim wanted to fix the throttle actuation before, as he noticed at the Iron Drift King they needed some improvement. I'm also curious what the tuning will do to the sound, and also how the power curve will look.

Tuning can’t change the overall sound. Porting head and camshaft design change the sound more.

@@Fk8td "Tuning can’t change the overall sound. " - not true "Porting head and camshaft design change the sound more." - not wrong ^_^

did you watch the video at all?@@Fk8td

not even mentioning the music, screenshots of papers, animations, storytelling and jokes

Seriously amazing work and dedication. I stopped editing videos because it took a lot of time and mine were nowhere close to this complex. And this was funny on top of all that.

No engineer I've ever spoken to, has had any clue how it's done. So I need better engineers to speak to, or find out myself ^_^

​@@maisteer I'd say somehow find someone at Yamaha who worked on the Lexus LFA, somehow they made that thing sound so beautiful

@@isaiah9639 They have the advantage of being able to do trial and error. Theory and/or computer simulation only go so far. Say the topic of eliminating drone: sometimes it's as unsophisticated as measuring the frequency response and working out what the droning frequency of the exhaust is and putting on the quarter-wave tube or Helmholtz resonator to cancel that out (or changing the design to avoid that) -- as much it would be nice to predict it precisely on the simulation or by theory. Anyway for what it's worth you can Google the Lexus LF-A exhaust design. It looks like it is a 5-1 collector with a pretty steep merge angle. It is true dual back to the rear muffler and the only crossover between the banks is inside the rear muffler somehow. It looks like the primaries are maybe 45mm (?) and it goes into either 60mm or 65mm.

Tim did an excelllent job... I didn't. Or it would at least sound good ^_^ We gonna figure out the rest for sure.

Thanks for smiling and for watching ^_^

I will try to make the sound better everytime, but not only in the editing software ^_^

@@maisteer thanks so much for your reply and videos! I find them informative ｡◕‿◕｡

After reading similar comments about colleges multiple times, what do they actually teach there? ^_^'

@@Chris-cy3uq I'd argue that even with even firing sequence, the exhaust sound from factory can be improved upon greatly. Having said that, I see where you are coming from, but I will still play around and see where I can improve!

Thanks for not forwarding them ^_^

@@maisteer

Getting the audio right seems to be the hardest thing for me ever. Not only with the engines. ^_^'
