How Porsche Perfected Intake Manifolds

[@EngineeringExplained]

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 👍🏻

[@HSHSTAR]

Just one question from where do you get these data?

[@prospectla6316]

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!!!

[@rochditidjani]

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.

[@lebaneezer1]

[@itsalgud1459]

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.

[@NaveenKumar-oj7xh]

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.

[@itsalgud1459]

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.

[@johnnguyen2592]

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.

[@Oldbmwr100rs]

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.

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

[@MeteCanKarahasan]

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

[@Onetwelvefourth]

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. 😀

[@Onetwelvefourth]

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.

[@Joshualbm]

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.

[@JonathanSias]

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.

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.

[@SoulTouchMusic93]

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!

[@92billly]

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.
