Does colder intake air have any benefits?

Hello,

I want to modify the inner fender liner on my AFN Passat to allow more air to flow through the intercooler, resulting in colder intake air.
Does it make a difference, or is it something you can just skip?
Sure, here's the translation:

'I would appreciate a short answer.'

Best regards.
Ronny.

Click on the corresponding link 'intake air temperature for Audi A3' in the menu on the left.

Hello Gremlin,

Oh man, this is so embarrassing... Thank you very much!
Then we can safely say that a perforated inner fender doesn't really offer any benefits, right?

Best regards.
Ronny.

I modified the bumper to allow more air to flow towards the intercooler (IC), so I cut out some additional openings and used a heat gun to soften the original air ducting plastic.
bent, so that more air can come into contact with the heat sink.
I also made a hole in the wheel well, at the level of the lower control arm.
in size 15x15cm. I repaired this hole using sheet metal.
riveted and the rear fender cover reattached.

Unfortunately, one can only imagine icon_mad.gif more performance.
Experience makes you wise.

Best regards, H-P.

Has anyone ever experimented with LLK (liquid lens kit) mounting?

That would be interesting!

See you soon.

Hi,

I have already conducted tests using a local exhaust ventilation system. Audi A6 2.5 AEL.
Specifically, I installed a radiator fan from a Golf behind the intercooler (under continuous load) after doing some sheet metal work.
It's quite a bit of work to assemble this thing, and there's very little space to work with.
Therefore, I also made a mistake => In my opinion, the additional cooling is significantly noticeable both when starting from a standstill and in city driving, but the effect diminishes on the highway. <<< In this case, the fan also burned out due to the lack of pressure equalization flaps. icon_sad.gif
I haven't had time to replace and improve the fan yet, but I definitely will. The car feels more agile from a standstill and generally more responsive (my impression; I couldn't measure it precisely, except for the hill climb test, where it was about a second faster).

Best regards, Frank.
