Been having a search about MAFs etc and came across an interesting topic about a guy with a BMW who heatwrapped his MAF and airbox. Claims it gave him good results. Not sure how effective it would be in the S3 engine bay but certainly got me thinking. Ok it doesn't look pretty but I'm not really bothered about that, if it keeps things cooler and helps it run better as if it and cooler than surely it could be worth a go?

What do the S3 boffins here think *cough* Tufty etc lol? :laugh:

im not an S3 boffin (yet) but i really dont see how this will affect a car performance....
cold air affects the performance but i dont think that happens thrue the MAF but thrue the "combustion"
so getting the MAF to be a bit colder...wont get the air to be colder
In some cars like earlier mercedes and bmw's, we used to do a trick that fools the car ecu so that he reads colder temp. in fact the trick made the ecu read always around 60 Celsus, and that would give the car some timing advance and more fuel injection from the mechanincal injection head and fuel actuator.


I would like to see this really working but im not able to find a mechanical proof...

thats my own un-professional thoughts :D
 
cant see it being worth much. maybe heat proofing the pipes AFTER the intercoolers too
 
It would have some potential benefit in a similar way a cold air feed works in that the air getting through to the turbo will be cooler and therefore cooler throughout the entire charge system, less heat for the FMIC to remove etc...

Not the prettiest install though as you say.... something like the Carbonio cold air feed works quite well though...

Seen this on a Leon recently and looks pretty good...

Feel how hot your maf and intake get, if it is hot then it is making the air a bit hotter. Air does get heated up pretty quickly. On my car its get too hot to touch but it is metal so im thinking of doing something about that.!
 
Yeah when I put my hand on the airbox and MAF after a run it's usually very hot hence why I'm considering trying this....
 
Keeping the MAF cool, therefore making the ECU think there is much more airflow (cooling the MAF element) will mean the engine will run lean....

More airflow, less fuel in mixture therefore the lamada readings will cause the ECU to correct and adapt

So pointless
 
You wouldn't be cooling the element though lad, just the air surrounding that area. But I understand your thinking.

The idea with this is to cool the air, thereby making it denser, thereby allowing for a greater fuel/air mixture.

Like a cold air feed. Cold air feed = colder, therefore more dense air = better power.

Good point but agreed. Would be the air in the MAF being slightly cooler - would never make enough difference to cool the element I don't think.

By the way JD09 you de-meshed your MAF mate? Just curious.

I've not mate, no.
