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 👍🏻
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!!!
"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)."
I honestly thought this intake manifold expansion would bring about 2° to 3°C cooling. However your drawing on the board clearly shows a reduction of 20°C. That is simply stunning, considering the engine block is still so hot.
It’s amazing how cars are designed and built these days! I am an old fart so I can appreciate how different they are. Thanks for a really interesting and informing video, Jason.
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.
Yes. Love it. Wish it was pushed more in the US education system.

I've worked on a lot of Porsche cars and this answered the questions I had for their strange "log" manifolds. it makes sense, cooler air is denser, also tuning, while important is not the only factor. Of all the european cars i worked on, I've found Porsche's to be very solid, reliable and easily serviced, with older mercedes not far behind.

It's very cool what Porsche is doing. After watching all these engineering breakthroughs made by them, I no longer wonder why their cars are so damn good.
Awesome video Jason! Porsche has always been my favorite auto manufacturer. If you ever plan on continuing your best engine series, I would strongly suggest you look at the v8 in the 918 spyder. 4.6l producing over 600 hp NA.
As usual a very concise and easy to understand explanation of Porsche's technology and how it differs from traditional intakes. Your videos are a joy to watch Jason, and you have even responded to me a couple times which makes me feel all warm and fuzzy!
I was surprised you said this method is counter intuitive. To me it’s fully intuitive. Expanding air or water tubes/pipes always improves efficiency. This is a pretty fundamental engineering principle. 😀
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.
I swapped the clever oem intake on my old mazda for an aluminum one. It was way lighter, but my favorite part was it had perfect resonance at 5000 rpm. Them pressure waves of the valves closing went right back into the cylinder to shove you back in the seat, and it made the most beautiful roar! Of course, I enjoyed the heck out of those 130 torques and 150 horses. So now I drive a truck with 150 torques and 130 horses. I haven't gotten into near as much trouble now, but it just doesn't sound the same.
They merely medicated the effects of reversion. Chrysler did almost identical thing in 1964 with their NASCAR intake that operated at 104% +. And when air is cooling it's Contracting, not expanding. But it is more dense and the expansion chamber and the short Runner means there's more available air to go into the intake when it's not under the effects of reversion. You're going a long way around the barn 2 explain a really simple fix that I've built in a sheet metal shop in the span of about half an hour in intake systems.
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.
Can I just say, your awesome I’m digging this unbiased information based channel you got, I’m learning a lot from these videos. Next time I got some spare change I think I’m grabbing some gear. Thanks man.
Man, this makes me want to redesign the subaru intake to reflect this expansion style. I have been working on modifying my older 96 subaru legacy to be more fuel efficient. 12% is a huge savings.
Peugeot had a plenum built into their 404 and 504 cylinder heads. On the 404 here was a short, single throated manifold from a single barrel carb that was watercooled. The ports to each cylinder were cast into the head for a few inches. These heads were very wide in order to accomodate the fournals. This allowed for very uniform temperature regulation of the fuel. It worked out to be very efficient. So, for instance, their 2400 lb 404 sedan would easily get 30 mpg from a 1600cc motor was reasonably peppy and could go 100mph.

Fantastic video. Another very interesting intake manifold to research was the Mazda VRIS system employed in the early 90's which had three controlled resonance modes. Thank you for another great video!
Very cool; the expansion cools the air. They make up for the lowered pressure by by supplying more air from the turbo. More air, colder air = better thermal efficiency.
oooh, now i get it! they use more psi, so they have even hotter air. that means a bigger difference in the intercooler. that makes it take even more energy out of the air, and when it expands it cool downs even further! awesome!
You're very good at explaining 'potentially explosive' material!!! Seriously you are easy to understand which makes your content similar to 'streetable HP'!-) ✌️🖖🔥

Hey! Loving the big white board ...if you ever want to get crazy, there are wall covering products that can be applied as a white board and can also come with magnetic backing! Just an idea, congrats on the awesome video!
As a refrigeration mechanic this topic has been extremely interesting. I myself have been wondering for a while why manufacturers/engineers dont design force induction engines to use a restriction control instead of a wast gate or relief valve to regulate the pressure. They could easily turn the intercooler into a condenser and create sufficiently colder air temp at the same intake pressure. I guess porsche are half way there congrats to them.
Subaru had a cool setup as well with a variable length intake on some of their turbo engines. By using tumble generator valves they effectively varied the intake length.

@@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.
