FAQ- Cold air/short ram intakes
Ok so i dunno if this has been kinda written up here (havent been on OH too long) but i think its time i made a contribution here about a post that we all know can come up too often. What is a cold air intake and what are the advantages to short ram intakes. Ill start the initial post and if anyone thinks i have missed out something or am wrong please add it and i shall update my initial post. hope u like:
i have an aem v2 intake, but for the preludes case it turns out its a short ram kind of intake. the v2 is designed for the greatest gains and in the preludes case its short ram, even if it says its a cold air intake. This will be different for other cars, I believe the V2 is is CAI for the integra?
WHAT IS A SHORT RAM INTAKE?
a short ram intake sits in the engine bay, the pipe runs to a position behind the battery. heres a pic of my aem v2

ADVANTAGES:
*Top end gains due to the free flowing setup
*Responce is greater than the cold air intake setups, due to the shorter flow for air to get into engine.
DISADVANTAGES:
On hot days "heat soak" becomes a factor, hot air is less dense than cold air and on a hot day there is alot of hot air in the engine bay. This can be overcome by building a heat shield kind of box around the pod but probly wont be as free flowing nemore.
* This set up is illegal if using an oil based pod, In Victoria(dunno bout other states) it is illegal to have an exposed pod in the engine bay. If you use a dry paper type pod like racinghonda uses it will be fully street legal.

WHAT IS A COLD AIR INTAKE?
a cold air intake runs the pipe through the engine bay and sits the pod in the wheel well, heres a pic of richards(racinghonda) setup, i believe its simota pipe with the Apexi Power Intake pod(shmicko!!!)

(note how the pod sits outside the engine bay)
ADVANTAGES:
*Its cold air diet means for a constant supply for cold air, no heat soak!!!better for power on hot days
*looks blingin!
DISADVANTAGES:
*long pipe is bad for responce
*in really wet countries hydrolock is a risk, this requires the full pod to be submerged (knee high puddle) with atleast partial throttle applied (over 50% id guess). It doesnt take einstein to guess that water in the engine=VERY BAD=VERY EXPENSIVE, hydro lock can be avoided by purchasing an AEM bypass valve.see pic below

ive heard its useless as it totally disrupts the airflow so u may aswell stay stock intake. It sits inbetween the two pipes, in richards pic notice the join above the battery, the bypass valve would be located there.
