Engineering Explained muito bom!! Manda uma alô pro Brasil!!

I'm, hope the same for you, and thanks for the additional info and the video, I find myself very curious about intake and exhaust and so on 👍🏻🤓 and very clever done by Porsche 👍🏻

Just one question from where do you get these data?

My mechanical background is not great at all so here is my question: You mentioned due to the expansion areas within the intake manifold that provides air cooling capabilities but must be turbocharged, what models within the Porsche lineup would use this type of design? I'm assuming only the turbocharged models but figured I'd ask the question. Thanks for the information!!! Keep up the good work!!!

Your new big whiteboard is amazing

Such a deep comment

I had to like the video because the comment lol. Also great video but nice ending

Totally cosmic. Wow.

and his drawing skills....

Not to mention how the camera is perfectly straight and perpendicular to the board. Quite satisfying.

So very kind haha. :)

"Now let's look at this graph of a baseline channel's awesomeness versus whiteboard size. In blue here, we have @Engineering Explained showing a 25% increase in viewer specific formula consumption (VSFC)."

Ben, You know how I know you're gay? Because of this comment.

Nerds! Lol.

Thanks for the like, @Engineering Explained I *love* your channel, have for a long time. Keep up the fantastic work! :)

Gallo 12 or 24? 24 seems to hold boost better.

So funny

Ha ha ha F&F jokes still works. Nice

The welds couldnt handle Vtec!!

F&F are still some of my favorite movies to watch... Don't watch them for the accuracy of information, just for the joy of it. After all I don't watch Anime because it is factual, it's all about the fan service :P

Agreed! People are awesome (a lot of the times, sometimes).

Yes. Love it. Wish it was pushed more in the US education system.

Its not all rainbows and unicorns. Almost every single manufacturer out there is trying to build their vehicles in a way they will fall apart after 3-4 years of driving, so people have to keep buying new ones. They make components that wear out quicker and electronics that fry and self destruct quicker to the point where buying a new car becomes more sensible since it becomes too expensive to maintain a 4 year old one. All german brands including Merc, BMW, Audi and porsche are doing it. Hondas are not that great nowadays either with their automatic transmissions becoming worse by the generation. So far I haven't seen very little evidence of toyota doing the same but I'm not 100% sure. If they make vehicles that last 15-25 years, they are hurting their own sales and bottomline.

Naveen Kumar Naveen, I don’t think your premise holds up when you look at the statistics. Overall, cars are lasting longer than ever, with the Asians, of course, leading the way. America is second, and the Europeans, the group you specifically mentioned, are the worst. Still, I think it’s a bit cynical to think that they’re trying to build lousy cars. Anybody who did something so foolish would simply get killed by the Asian manufacturers! I also have to take exception to your throwing Porsche in with Mercedes and BMW regarding reliability. I don’t know a lot about their SUVs and their passenger cars, but I know the 911 still has a reputation as being one of the most reliable sports cars money can buy.

I somehow agree with naveen but not to the whole extent. Manufactures are not making their profit from selling you cars, but instead selling you warranty and servicing your vehicle. Part prices and labour have sky rocket recently and most manufacture knows the trend of DIY individuals are growing fast. Hence this is why most cars have a very sophisticated electronics so only the dealer can trouble shoot which is where their profits are mostly from.

Ha, thanks! :)

@@EngineeringExplained I'm at a loss for understanding why this last minute expansion in the intake manifold is better than say, using a larger intercooler farther upstream?

Danny Daskalakis make that 2

once it hits 4 million subs he will use a wide Blackboard and chalk to illustrate hehehe

Edit 3 mill now

Thanks, glad you enjoyed it! 😁

Facts ! People are just haters to say otherwise.

No doubt.

People will find A way to ruin it with A cold air intake or something like that.

@Ismael Reynoso Jr it's still a Volkswagen it's gonna have problems

@Ismael Reynoso Jr you must be unfamiliar that Porsche is the most dominative manufacture in motorsports. With the 911 being the most dominative production car name plate. Although The bmw e30 m3 as a single generation model car has the record for most races won.

They don't waste money on styling, more engineering money.

Just don't wreck it or you will probably die. Way too fast not enough structural integrity. Kinetic bomb.

@@tcroft2165 Its not the placement of the engine that wrong. Its the driver who doesn't know how to operate a rear engine vehicle.

Wouldn't a bigger intercooler accomplish basically the same thing? Without sacrificing the pressure boost from the induction intake?

Hot air accelerates due to "low pressure". Larger manifold would instead increase the pressure.

You left out the most impressive part, it weighs 135 kilos, which is less than a ka24de four cylinder

Happy to hear it, thanks for watching! :)

Thanks for your excellent attendance!

So happy to hear it, and thank you so much for watching! :)

Thanks Mark!

😂😂

@@EngineeringExplained Why are various degrees not offered through KZfaq?

@@Michael-fw5ef right now you can only get flat earth degree, anti vax degree, chem trails degree, and alien/world govt degree but theyre looking to expand

Well, air is not like goose down. You can’t easily cram it. A basic principle of dynamics is larger airways create higher pressure. Ask anyone who installs HVAC ducting for example.

Haha, thanks!

Thank you!

@@jackpoage5419 This was noted. However, the lower temp, and decrease in knock are also valuable. The improvements are still quite good.

YES 2,001,659!

It more so changed the size

Not entirely correct: two laws; Boyle's law, the one about pressure, volume and temperature interdependence and also Bernoulli's law about cross section pressure and speed: So what is missing in this video is that when you increase the cross section of the piping speed slows down but pressure increases, quite the opposite of what is explained in this video. A traditional trumpet intake is like the nozzle on a fire hose, widest at the start where the hose connects and pressure is highest and narrow at the business end where pressure is zero but speed is high. The reason this is used on NA engines is because you want high speed air going through the valve helping with mixing, not to increase pressure, it actually reduces it. So going the other way, expanding the cross section, you slow down the air, but increases its pressure, and temperature! However I don't think neither Porsche or our friend got this wrong, so what is explained in this video (which is also mentioned) is for a specific rpm and load where the pulses from the valves actually go into a resonance with the chamber , so that the combined effect makes pressure drop in the wide section of the manifold! Just think about a turbocharger: The impeller does not make pressure, it increases the speed of the air as it leaves the circumference of the blades. Turbo pressure first happens when that air is slowed down in the annul around the turbo. This is why we have turbo surging when the flow is too small, no acceleration of air is possible and the impeller just becomes a solid mass of rotating air, doing nothing.
