@prospectla63165 жыл бұрын
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!!!

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.
@itsalgud14595 жыл бұрын
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.
@johnnguyen25925 жыл бұрын
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.

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.

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.

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.

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.
