Well, seeing as I cant sleep, been thinking about adequate cold air feeds that I'm going to use for my Apexi induction kit when i fit it.
Using one of MikeWarner's pics of his induction kit (hope you don't mind) i've drawn 3 red arrows where I think cold air feeds should be directed.
Basically my theory is, have one or two vectra c pipe adapters fitted to the front of the car, with 3 outputs from that (custom made).
(White dots represent the end of the feed)
The left hand feed will feed cold air to the left side of the induction kit, the middle one will go underneath the induction kit and feed the underside of it, and the right one will feed the right side.
Does this seem enough cooling? will the air actually get into the engine properly. Thinking about my existing setup, or the normal coupe turbo airbox, air goes directly into the filter and then around to the crossover pipe (always in a forward flowing motion).. this induction kit setup means air has basically got to turn a 90degree bend in order to feed down (is this right, or lack of understanding)?
Even though this picture isnt exactly artistic, it identifies potential feed positions:
So back to what I was saying before, the red rectangle shape would be the larger veccy c intake pipes, feeding 3 routes... or another way (or an additional way) would be having a cold air feed pipe behind the bottom of the bumper, also flowing air to the underside of the induction kit..
Then brings the other question, could there be too much air?
