Can this guy just be my teacher? I'd listen to 20 lectures from this guy just because it's so interesting and he breaks it down to very understandable levels
The /Engineered series is one of the best technical series on the entire youtube to this day. Almost 10 years of this video and omg, so truthful. "How much for how long" is such a great statement. Heat and fatigue are the cornerstones of all those racing machines, just beautiful.
The best guy on the channel at explaining things. He draws just barely enough to get the point across, instead of pretending like he is making a perfect technical drawing and then stammering to explain it. I like this guy's style.
This /ENGINEERED adds so much depth to this channel, I love this segment. And what makes it so good is it seems all the presenters you have on this segment seem so passionate about whatever they talk about.
These new videos are top on my list for anything that Idrive has ever produced. Actual people working in the field building/testing/designing. This series gets an A+ all day
I love it! Although it's more or less like my every day conversations as an automotive engineering student, it's nice to hear it from someone whit a lot of hands on experience.
As an engineer, I could geek out on this stuff all day. I love Engineered! As someone who spent almost six months of this year trying to correctly balance the cooling system on an old muscle car, I can personally state how important all these things are even for a road car. Heat management is a pain, but it's worth the struggle to get it right.
The aluminum process he describes is not meant only to increase surface area, it is meant to induce turbulent flow as opposed to laminar flow, and turbulent flow is MUCH MUCH better at convective heat transfer. Without doing maths, I would bet that the turbulent flow as opposed to laminar flow is a more dominant effect relative to the increased surface area.
Phil Aufdencamp That would typically depend on the length scales at play. For any practical Reynolds number, I'd expect the turbulence length scale to be several orders of magnitude smaller than the surface roughness. That said, I don't believe the material can conduct heat effectively enough for the added wetted area by itself to be the deciding factor, so that goes back to the boundary layer as you suggested.
This video is absolutely fascinating. The format is simple, but so packed with information, I might have to watch it several times to soak it all in. Well done.
If my heat transfer teacher used his examples, especially the heat exchangers, I would've actually been more interested in the class and gotten an A. Thanks Drive for this video!!! Can't till your next "engineered" videos!!
This is so well done and interesting. So informative. Mad props to whoever did the sound mixing, the music goes really well with the speech. He explained so many things that I didn't know before. Awesome.
this episode is the most insightful piece of information about car design I can remember to have seen, ever. I was aware of heat as a problem in a lot of parts - especially the engine of course - but never got the big picture. That will completely change my view on race cars. Thank you very much.
Please more technical videos like this! I usually watch car videos waiting to for that one piece of information that one detail I've never heard or thought of before. I didn't feel like that once during this video.
I rarely comment on youtube but this vid was great. Thoroughly enjoyed listening to his guy. Learnt so much in 18 mins, keep this kind of content coming.
Towne Pass, Death Valley, CA. Where cooling is put to the ultimate test. On any given day, you can find several manufacturers testing, from Hyundai to Audi to Peterbuilt to GM. I've seen Toyotas with water tanks filling in for passengers, Mazdas pulling trailers. Death Valley is THE PLACE for spotting test cars.
I love how one of the crew in the background could be heard saying "wow" at just about 9 mins, it was simultaneous with my reaction, which was the same.
I've seen most of these engineering videos and they are amazing. You get to know soooooo much and realize how little you know or how much you assumed wrong :)
This is going back to basics at it's finest. Great video! Thanks guys. 19 dislikes??? I can't understand that like they probably don't understand that logic in the video.
There are those who sound wise but know nothing and then there is those who know it all, but almost can't explain it, but yet i still understand it 100%
This was awesome. I feel like I learned alot of insightful things and actually kept me hooked throughout the whole video. More videos like this please.
I think at 8:52, it's not just about making the area bigger with that tiny ridges, but also make the flow around the cylinder turbulent(from laminar flow), which also helps "remove" the heat. My mechanical english is not the best but I think you understand.
I really enjoyed this video. Leaving out the annoying background music would make it much better when he is speaking. The engineer knows his stuff and it was interesting info, thanks.
Very nice comments about something people don´t realise how important it is, all poor efficiency of power generators becames heat, and that heat has to go to the enviroment before melts something, well explained, congratulations.
+Nathan Sievers If you really need more stuff like this. go read a book about mechanical engineering... Do you need knowledge or entertaintment. If it's knowledge pick up a book.
The argument for heat being the limiting factor really parallels with what I do in my own mechanical engineering career. Even pure structural analysis requires some consideration toward influence of environmental factors, temperature included. Thermal analysis is so prevalent that even my dissertation mainly revolves around controlling heat.
Wow....amazing, eye-opening videos!! Please keep them coming! I'm going to be making some RUclips videos as I do modifications to my newly-purchased 2003 C5Z06, and I will absolutely be referencing these videos as they contain such a wealth of information. Thanks again, subscribed!!!
good information. Thermal Dynamics is a complex aspect of vehicles that isn't usually focused on. i might only kind've sort've be a car person, but informational stuff is always interesting.
Mind. . . Pewwwsshhhh~ This video is freaking awesome, hope to see more /ENGINEERED videos, if they're even half this good you're doing the right thing!! God its been so long since iv watched something on /Drive . . . Glad to see you guys are doing the user free content again! :D
Guys, I love you and your channel. You are like a team group of people? I know from the channel only Vince "Built" Griffin. I am relatively new, but totally loved my first vid from you - "Legendary Subaru EJ: 1,000-hp Performance". The music there was ASTONISHING. Up to now I have fully watched it about 5 times. Soon I will be owner of one stage 2. Trying to get as many knowledge of the known problem fixes as possible. Killer B Oil Pickup was very helpful!
So many people modify cars for a certain street cred, or to satisfy an emotion of what the car should be, instead of modifying cars strictly for the purpose of their choice. If I want to rip the shit out of my car on the canyon runs that I do, what I feel I need now is custom tune, solid intercooler pipes, upgraded head lights (I do the runs at night when no one is around, and my stock lights suck), aftermarket seats because the 2015 evo comes with lancer seats, and I'm fatigued after a couple runs by not being held properly. The suspension, stance, power, and all this stuff, I realized definitely didn't need to be changed for the nature of those drives. In fact, I just last night started improving my skills to the point where I can now dial out some understeer, and that's it. This is far from the most fun modification path, as I envisioned something totally different for my car in terms of how I wanna build it (much more extreme). However I can't see it performing well anywhere but on perfectly smooth roads after I do so This is one of those things we never really talk about, but these runs really got me thinking how important it is to be mindful of this stuff when modding your own car instead of just trying to make your car as cool as possible
I see you do canyon runs. Here's my 2 cent. Tires, suspension and brakes make a car fast. Road knowledge makes the driver fast. Power is useful in the straights.
+Yousuf Zuberi absolutely right and since my purpose is something quick and fun on the street and good enough for the occasional trip to the drag strip a v8 s10 fits my purpose. yes i do like bombing my car/truck down back roads ,but im also kinda in love with high power light trucks...
+Yousuf Zuberi Exactly right. I have spent the last two years playing with nothing but my driving and the suspension on my car (1990 Miata, super soft from the factory) To make it a blast for autocorss, but still livable on the road. To most people, it just looks slightly lowered, but I love letting people take it out for a spin and seeing their reaction to just what a bit of tinkering and focusing on one thing can do. I have reached the limits of the stock control arms and the shocks I have (spring rate that is comfortably controlled and alignment and balance that can be achieved) so now, after 2.5 years, it is finally time to add some more power. The first thing I am doing, before even installing the supercharger, is reworking the cooling system and making sure it is up to snuff, even though I am only going to be bringing the car up to about 150ish hp (about 35 more than stock).
+Yousuf Zuberi i would say that for caynon attacks u need for sure tire that u can read without a problem and know where is the grip.. And good brakes&cooling.
Very interesting. I started to encounter heat problems on my second trip to the nurburgring when i actually knew the track, previously i did 3 laps back to back in my RS6 (c5, tuned to 533PS) and it was fine, oil temps stabilized at ~125c. The second trip I was on the throttle harder and longer, oil temps kinda stopped going up at 130c (it's good ester based oil so I wasn't too concerned) but halfway through the second lap the coolant temp warning started going nuts on the dash so had to back of as soon as i could get out the way of other traffic. I more-or-less thought you could go indefinitely with a good modern car but looks like I was very wrong.
More videos like this please, very interesting
+bumblebeebob99 There's more coming.
+/DRIVE looking forward to watch them
+/DRIVE excellent
Awesome!
Very interesting indeed! I loved how he sketched what he was explaining to help make it more visual
Someone who actually knows what he's talking about, how refreshing.
Not bad for a guy who didnt finish high school! Like Mark Twain said: Never let school interfere with your education.
I barely have an attention span of 30s for most RUclips videos but this kept me hooked for the full 18 mins. Great work
Same man and video didint feel like 18 mins more like 3 min.
+dombower wowwww didn't even realise it was 18 mins long.
Can this guy just be my teacher? I'd listen to 20 lectures from this guy just because it's so interesting and he breaks it down to very understandable levels

GREAT VIDEO!! :) I'd love to see more of these kinds of videos
This is the best video from drive
I love it! Although it's more or less like my every day conversations as an automotive engineering student, it's nice to hear it from someone whit a lot of hands on experience.
These are like proper Automotive Engineering lectures. Great resource.
As an engineer, I could geek out on this stuff all day. I love Engineered!

Respect for this Man here. Betim B.. World is a better place with BBI in it!
I enjoyed watching this whole thing, because you can tell he has a genuine passion for what he's speaking about. Love it.
this guy is awesome. i could listen to him explain the technical challenges for hours. it's kinda like listening to Jackie Stewart talk about racing
This is, without a doubt, the best video ever posted by /DRIVE
one of the best videos on this channel. This guy is the type of person I want to watch.
Please, more of this kind of informative pieces. Mr. Brisha is an excellent teacher.
The aluminum process he describes is not meant only to increase surface area, it is meant to induce turbulent flow as opposed to laminar flow, and turbulent flow is MUCH MUCH better at convective heat transfer. Without doing maths, I would bet that the turbulent flow as opposed to laminar flow is a more dominant effect relative to the increased surface area.

This is such an incredible video to be posted to youtube! I cant wait to see more of this! Thank you for the post!!
Man I love this Engineered setup. Such awesome advice from people who have been doing this forever.
The moment he said thermal and dissipation I knew he was speaking my language. Great series. Keep doing the good work guys.
This video is absolutely fascinating. The format is simple, but so packed with information, I might have to watch it several times to soak it all in. Well done.
One of the best videos Drive has posted, get more videos like this up.
If my heat transfer teacher used his examples, especially the heat exchangers, I would've actually been more interested in the class and gotten an A. Thanks Drive for this video!!! Can't till your next "engineered" videos!!
This is so well done and interesting. So informative. Mad props to whoever did the sound mixing, the music goes really well with the speech. He explained so many things that I didn't know before. Awesome.
Right on! Heat is and always will be THE most important engineering challenge in most of industry, but performance oriented engineering especially.
this episode is the most insightful piece of information about car design I can remember to have seen, ever.
I was aware of heat as a problem in a lot of parts - especially the engine of course - but never got the big picture. That will completely change my view on race cars.
Thank you very much.
Need more content like this. Like Cornerer stated, thanks for not only offering this to the Drive+ crowd.
This was absolutely fascinating but also understandable to those that like engineering but don't quite grasp the mathematics. THANK YOU DRIVE!!!!!
This is seriously the best video you have ever made. DO IT AGAIN!
can't believe this is actually free content+
You guys are awesome!
Please more technical videos like this! I usually watch car videos waiting to for that one piece of information that one detail I've never heard or thought of before. I didn't feel like that once during this video.
So glad you guys started this segment. Honestly, super helpful.
I rarely comment on youtube but this vid was great. Thoroughly enjoyed listening to his guy. Learnt so much in 18 mins, keep this kind of content coming.

Such a wealth of knowledge. I wish that I could sit and talk with this guy.
great episode, very eye opening for the bolt on boys
This is probably my favorite segment you guys have done since the inside Koenigsegg series
Matt was just talking about a nerdy show like this not working out on the podcast. Glad to see youguys giving this a shot
/DRIVE, this is one of your best series yet. Keep it up.
I love how one of the crew in the background could be heard saying "wow" at just about 9 mins, it was simultaneous with my reaction, which was the same.
I've seen most of these engineering videos and they are amazing. You get to know soooooo much and realize how little you know or how much you assumed wrong :)
glad I came back to this video, I forgot a lot of this info. Betim dropping some knowledge on us! These are great Drive, thanks
This video is priceless for amateur tuners like myself. Absolutely priceless.
This is going back to basics at it's finest. Great video! Thanks guys. 19 dislikes??? I can't understand that like they probably don't understand that logic in the video.
This is a fantastic segment, can't wait to see more /ENGINEERED!
Best series yet imo. I really enjoy the deep in depth geeky stuff.
This was the most informative vid about cars I have ever heard. Makes complete sense about heat exchange. Wow!
Great video. I would love to see more videos like this. Listening to a expert on thermal dynamics is really awesome
Finally... Not "tuner/hipster" bs. Just some real knowledge/Engineering. Thank you!
Huge respect for the guy sharing these secrets to us...huge huge respect!
One of the best videos I saw in this channel ever.
thank you guys for sharing this video to us. we need more videos like this on RUclips.
I'm pretty uneducated when it comes to engines and the like. This taught me a few things. Thank you very much.
Can't get enough of these. Keep em coming :)
A reason to start watching /drive again. Thank you!
ive learned more in this video than i have in 10 years! more videos like this please
This is awesome! Thanks so much for taking the effort to make a nicely produced video that has detailed information in an interesting format!
There are those who sound wise but know nothing and then there is those who know it all, but almost can't explain it, but yet i still understand it 100%
This engineered series is brilliant...big thumbs up
Every car guy needs to watch this. I shared it on all my social media.
Something like this on suspension would be another killer vid.l
Engineered might be one my new favorite series
Please please please make more videos like this. I love these.
This was awesome. I feel like I learned alot of insightful things and actually kept me hooked throughout the whole video. More videos like this please.
9:24 'We actually just said ffffffuck... I mean forget it'
i don't know if /engineering is going to be a series, but it should be. car loves love this real nerdy stuff! make more please!
I think at 8:52, it's not just about making the area bigger with that tiny ridges, but also make the flow around the cylinder turbulent(from laminar flow), which also helps "remove" the heat. My mechanical english is not the best but I think you understand.
Simple words to explain complex matter.
Well done !
Another great video from /Drive
Amazing series, looking forward to watch new chapters!!
very interesting and knowledgeable. please upload this kind of stuff more often..
This is some good shit man!!! That's alot of racing to come to realize those things that are there waiting to be discovered.
+Jose C. Rivera but thats all just engineering insight for performance. People just explain it better like this dude.
Listening to him makes me excited to do some of these modifications to my future Supra.
great information, I hope to see more of these kinds of videos here.
I really enjoyed this video. Leaving out the annoying background music would make it much better when he is speaking. The engineer knows his stuff and it was interesting info, thanks.
this was eye opening, good stuff guys. love these engineering episodes.
excellent video! this has renewed my passion for the cars and engineering. thank you for the wonderful insight into your work!
Very educative, I loved the format and learned a lot. I'd love to see more of this !
I like this /ENGINEERED series. I learn so much.
Brilliant video, can't wait for more of these. Will help me so much over the next year or so.
Very nice comments about something people don´t realise how important it is, all poor efficiency of power generators becames heat, and that heat has to go to the enviroment before melts something, well explained, congratulations.
This is awesome being a third year mechanical engineering student who loves cars
This guy's very good in explaining clearly.
I need more stuff like this! Anyone have any suggestions?
+Nathan Sievers There's more coming.
+/DRIVE looking forward to it.
+Nathan Sievers Engineering explained
+Nathan Sievers If you really need more stuff like this. go read a book about mechanical engineering... Do you need knowledge or entertaintment. If it's knowledge pick up a book.
philip s Good call. Currently an engineering student. I like visuals like this. Brings the stuff I read to life!

as a former student in mechanical engineering i found this very VERY interesting
:)
Please, please give us more of this type of content. Please.
I really enjoyed this. I think I could have even handled some general heat exchanger equations.
