im thinking of doing away with my k@n setup and going back to a stock box with a home made ram air type deal from behind the grill like a popular thread here talks about.
this morning i went for a drive of about 20 miles total. half of it i had a wireless thermometer under the hood 2 inches from my k@n open air filter that was surrounded by a heat shield that came with it. so going down the road at 55-70 mph with the outside temp 65 degrees, the temp was anywhere from 68-72 degrees. i decided to go out this gravel road and kept it in second gear going 10-25mph and most of it was shaded. the temp then went from 72deg. to 91deg towards the end of the road.
i decided to turn around and go back the same route as i took to get there. only now i moved the thermometer right behind the passengers side grill slot next to the head light.
(this is where i plan to have the opening to pipe the outside air into the stock box in a ram air type effect.)
i changed the location in 2 minutes.
upon starting the drive back the outside temp was now 67degress. As i drove again keeping it in 2nd gear staying at 10-25mph, the temp went from 91 deg to 72 in 5 minutes. (temp updates every 5 minutes) the next 5 minutes showed a reading of 65 degrees. when i got back on the freeway, i stayed at 70mph for a good 8 miles. the reading at that speed showed 59 degrees.
BIG DIFFERENCE!
dont know exactly if that would show much hp gain or mph gain, but either way, it will be much cooler air going into the engine and thats a good thing. And just for kicks, i went inside a store for 15 minutes before i changed the location of the thermometer, and in those 15 minutes the under hood temp at the filter went from 72 to 103 degrees! i cant wait until summer weather to test this again.
more accurate test can be done as i was using an atomic clock with its separate temp unit for a second temp reading. ild like to have a real time setup (at least every 1 second readings) to see the underhood and outside temp at the same time.
