intake air temp. air box. vs knn cone filter open to engine bay. 2002 allroad
 

over the next few days/ weeks im going to be running some tests on my intake air temp. i have a vag com coming, that will hopefully be able to tell me my intake temp. im going to be testing the temp, and possibly hp, and w.e else i find usefull. in all the different scenarios. i havent seen any other write ups on this. does anybody have any suggestions or things that they would like me to test?

ok. so after multiple tests. i have some results to show.

stock airbox with ram air. vs cone filter after maf sensor.

Attachment 31419 vs Attachment 31420
I tested 3 different scenarios.

- idling for 25 mins

- driving 19 miles at 75 mph

- and 3-4 miles of stop and go traffic


__________________________________________________


So after idling for 25 mins my results were

- cone filter @ 34*F outside for 25 mins = IAT of 145*F

- stock setup @ 38*F outside for 25 mins = IAT of 136*F

--So that means that the stock setup ran 13* cooler


During driving for 19 miles my results were

- cone filter @ 36-38*F outside = IAT of 51-59*F

- stock setup @ 36-39*F outside = IAT of 57-62*F

--And that also means that the cone filter ran about 2* cooler


And after 3-4 miles of stop and go driving

- cone filter @ 34*F outside = IAT of 91*F

- stock setup @ 42*F outside = IAT of 107*F

-- And the stock setup ran about 8* cooler here






Im honestly surprised that the stock setup wasn't significantly cooler than the cone filter which is completely open to the engine bay.

Fixed :D


Also, try a cone filter with some sort of heat shield so that the heat from the engine bay doesn't attach itself to the filter and becomes more of a heat soak, than actual power/breathing room.

jeez, i really need to fire my proofreaders. hah . yea, ive been looking into a setup similar to the one the ricam78 has. but i think i will stick with the stock setup until i go stage 3+.
