Forum behavior, air filter, scope of delivery

I'm sorry to say this, but the behavior in this forum is like being in a kindergarten. (K&N air filter posting)

The administrator doesn't even read the posts; they simply declare them incorrect, while often writing almost the same things in their own posts and straying from the topic.
Then the thread will simply be locked, and that's it! Admin, grow up, you can't force your opinion on everyone!

Hello??

Can't anyone see that there are other people who are right, and that some people can't tolerate that?




As soon as he reads this, he will delete my login and the entire thread!! Please be aware of this.


I asked a question earlier, and I'm getting responses from the admin. It's like they're saying, 'How do you not know that? I know, but I'm not going to tell you.'
Nobody is born knowing everything, and if I had the answer to my question, would I even be asking it here?
hardly.



Different people have different opinions, that's perfectly clear!
But that's not so bad!
Best regards,
Ingo

Hello Ingo,

As in all forums with more than 10 members, it is necessary to adhere to certain rules. This primarily includes reading the existing posts. To make this easier for new members, Rainer created a database of error messages. I truly believe that this facility is unique and extremely valuable.

I also took a look at all of your posts. Unfortunately, I have to conclude that you did not apply the aforementioned approach (see especially...). Your post "Can a 10-cent tuning be applied to the SDI?".

Furthermore, I believe there are many people here who are interested in helping members with problems or conducting tests and experiments (Rainer and Ulf, in particular, should be mentioned).
It is inappropriate to simply discredit them by labeling them as ignorant or similar.

Therefore: Please think about yourselves first before posting such things, and don't choose the easy way out by shifting the blame.

What was wrong with the '10 Cent Tuning' thread?


'Sorry, but how am I supposed to know if the SDI has the same pin configuration, let alone offer the same tuning options?'

That wasn't mentioned in the instructions because everything there refers to TDI models. I simply have a car that's built in small quantities.
The reference to the TDI models is completely justified, no question about it.

I certainly didn't want to belittle the effort that others put into their various attempts; on the contrary.

I discussed the issue with the air filter a few weeks ago with a professional and a lab technician here, and they both shared the same opinion.

I always thought that in a forum, you could ask a question and receive a relevant answer.

Okay, there are some bugs in the K&N thread...

1. The channels will be polished to improve the mixing process! That is unnecessary with direct injection engines.

'The volumetric efficiency of an engine is the ratio of the pressure inside the cylinder at the intake valve to the ambient air pressure. This explains why the effects observed in turbocharged engines are so small!' However, it does offer a minimal but noticeable improvement with the vacuum cleaner.

It is also no longer necessary to draw in more air to achieve a better fill level (which is, of course, impossible!). However, the reduced flow resistance is definitely noticeable here.

However, the effects are very small and offer little benefit for turbocharged engines, and are minimal for naturally aspirated engines. Unfortunately, these effects cannot be measured based solely on the air mass/volume.

In conclusion, the turbocharger's filling level cannot be significantly improved, whereas it is more feasible to improve the filling level in naturally aspirated engines.

But please don't suggest open-style intakes... I've explained the negative effects in the thread (intake length, heat, etc.); they're worse than anything else.

The administrator sets the rules, and it's that simple. He provides the storage space, pays for it, and also spends a lot of time on this website and its articles.

One rule is that people should acquire a certain basic knowledge before posting, in order to maintain a certain level of quality in the forum and avoid questions like 'Where is the diesel filter?' There are books available on this topic for very little money, and the absolute minimum you should expect is to read something like that and at least have some basic knowledge about your car.

And once you have some knowledge, you can easily realize that you probably can't get significantly more horsepower from an SDI engine compared to a TDI, and that arguing about 3 horsepower is pointless, because nobody really cares about 3 horsepower.

When the same question, which has already been answered three times and discussed even more often, is repeatedly asked, one wonders why one should bother to answer it, especially when the person asking hasn't even bothered to do a little bit of research themselves.

Finally, I would like to quote Goethe: 'He who disapproves of the laws must leave the area in which they apply.'

Hi Ingo,
Are you the (SUPER)Ingo who also wanted to attend the 86c forum meeting at the Dreifelder Weiher, but couldn't because you weren't known?

Regards,
Steffi H.

@ Steffi H.


It's kind of yes and no. I'm not registered as a regular poster. Someone else has already used 'my' nickname on the PCR Forum. Maybe I should register as a regular poster again. But I'm not always there, either.

The post you're referring to was from me, although I only asked where the meeting was taking place. I generally don't go to meetings that are too far away, otherwise I would have gone to Castrop. Unfortunately, there's also never enough time.



@ Docter

I either always phrase things ambiguously, or someone else does.
Polishing should only be considered as an example, as it has a similar or identical effect to a sports air filter. A sports air filter has low resistance to the intake air, which reduces the intake effort. As a result, the overall efficiency increases. It's not a significant increase, but it does increase. Hmm, how should I explain it?

The efficiency, mathematically speaking, is the product of the individual efficiencies.

Nges = N1 * N2 * N3 * ...


Okay. Overall efficiency.
Nx = Partial efficiency.


I hope this is now understandable. If not, I'll give up.

Best regards,
Ingo

then it's better to give up...


I already explained in detail why the parts are polished.

The lower sections of the intake manifolds are often polished as well. This is because, in direct injection systems, this is where the air-fuel mixture is formed. And that's where surfaces come into play.

I also explained the influence of the reduced flow resistance!

Keyword: Filling or Fill Level!!! Please see above.

And what determines the fill level? The pressure in the cylinder, which is in turn determined by the turbocharger. The benefits of a lower flow rate are marginal, if any.

With a naturally aspirated engine, the influence on cylinder filling is greater, and the pressure inside the cylinder is not determined by the turbocharger. Thus, changes with slightly more than a marginal
Furthermore, gasoline engines have other effects that can negate any potential increase in performance. But that's not the topic of this forum!

2. The volumetric efficiency of an engine is the ratio of the pressure in the cylinder at the intake valve to the ambient air pressure.

Please provide the text you would like me to translate from German to English.

It is also no longer necessary to draw in more air to achieve a better fill level (which is, of course, impossible!). However, the reduced flow resistance is definitely noticeable here.


I'm not an expert on engines, but I have a question:

You state in the upper part: 'Fill level = Pressure in the cylinder / Pressure of the ambient air.'

'Also, to achieve a better fill level, less air needs to be drawn in.'

Assuming the ambient pressure is constant, how do you increase the fill level if pressure equals mass divided by area? To increase the pressure, more mass is needed, since the area is fixed. And more air mass means more air. Or am I wrong?

Apart from that, I consider sports air filters to be nonsense in TDIs for the reasons I've mentioned multiple times.

Due to vibration effects, the faster inflow of air, and other minor factors.

@Doctor

So, I'm not entirely satisfied with it yet.

'Resonance effects: I can imagine this being a factor in carburettors, and it's probably implemented through adjustable intake manifold lengths (in my opinion).' I can't quite picture how that would work with a turbocharger (which operates under pressure).

And for me, 'rapidly flowing air' simply means more air per unit of time.

I'm not even talking about the turbo anymore; all of that referred to naturally aspirated engines. With a turbocharger, the volumetric efficiency doesn't improve. Because the pressure is generated by the charger.
And yes, with vacuum cleaners, different lengths of suction tubes (also known as variable-length suction tubes) are used, and the effects are utilized at different speeds. With a fixed length, there is only one optimal speed.

Okay, then that's fine. I just thought that because you mentioned the difference between naturally aspirated and turbocharged engines in a previous post.

We are of the same opinion, then.

@Doctor


I just realized that we haven't been really communicating well with each other. In your first post, you wrote exactly what I posted in the other thread.
One person writes about turbochargers, while the other writes about naturally aspirated engines.

It is also no longer necessary to draw in more air to achieve a better fill level (which is, of course, impossible!). However, the reduced flow resistance is definitely noticeable here.

Hm, where did I deviate from the topic in the K&N post? First of all: a search for the word "air filter" already yields numerous posts on this topic, so anyone can do their own research. Those who haven't had enough can check the posts in the old forum, where the topic was also discussed extensively. I've developed an allergy to the term "sport air filter." Because they offer nothing of subjective value, some people make a significant profit from them and tirelessly promote them, I have conducted numerous measurements to substantiate my subjective impression with facts. These facts are available for anyone to see, and if you can't accept them, there's nothing I can do to help you. However, I object to posts promoting aftermarket sports air filters, precisely because I am aware of these facts. I have locked the thread about K&N because I believe the topic has been discussed sufficiently.

Can't anyone see that there are other people who are right, and that some people can't tolerate that?

If you had followed my posts for a longer period, you would have noticed that, like any other person, I am also capable of making mistakes. The thing I'm least worried about is being accepted. Yes, I will delete this thread in a few days for the following reasons: - It consumes storage space, but it doesn't provide any insights that would be helpful to someone who is having problems with their TDI. - because it doesn't have a "deterrent" effect on future "smart poster" users, as they probably won't use the search function anyway (based on experience).

Hmm, was was that, the 10Cent - SDI post or the question about the diesel filter?
As previously mentioned, a certain standard must and will be maintained here.

Best regards, Rainer.

Unfortunately, in my opinion, there is some new information in the thread, specifically regarding the filters.

I personally think it would be more helpful to rename and verschandeln up the thread, because the current title probably won't attract anyone's attention here.
