Hey,
I had a question about my complete cold air intake system. The hose coming down from the filter system used to just go straight down towards the ground. I figured that picks up tons of dust and also worst of all, road heat. So, i placed it behind my grill. The rubber sheet can be modified slightly to just neaten things up, but i was wondering if this will help me at all. The hose end is at about a 5-7 degree angle right now facing the front of the car. I can also lop a little off one side to allow air to move through easier. There is a bend in the hose now, but i believe the higher amount of (colder) air will be better to reduce turbo lag. If i am wrong, it wouldnt be the first time. Any valuable input would be great. Thanks.
There are those who say the ultimate location is locating the inlet hose at the left Hi beam light location. Of course, you have to remove the headlight.
I'm not an authority because I have my hose at the left air dam location. Many people disagree with this location, but it seems to work ok for me. I've never done any tests to prove it one way or the other.
It would be easy to test. All you need is about 10-12 feet of open transparent hose with about a foot of water in it. Tape one hose end at various locations on the front of the car. The other end needs to be in the car with the open end vertical and where you can observe the water. When you drive at any speed over 60MPH, you will see the water column move up in the hose toward the open end. Put a piece of electrical tape around the hose to mark the height, and test a new spot. When you have found the spot with the highest pressure, this is where your air inlet should be. Always drive the same exact speed for each test. If I remember correctly, you have made a rudimentary manometer. Certainly not laboratory grade, but every bit as effective.
If anyone decides to do this test, I'm sure the list members would like to see the result.
What about putting a fan at the open end of the hose, as to cause not only constant, more efficient feeding, but also swirling air. This will move the turbo even faster. I am just throwing out some ideas right now to find the most efficient way to run. Thanks.
