I have been reading the fogged air box better intake posts and have since toyed with two ideas. I was wondering whether or not either have been done before and general thoughts.
The current intake of my 2002 2.2 is to the left of the front left headlight and around it. When the bonnet is closed air has to come into the space before the radiator and with apparent difficulty make it into the narrow gap.
Below are two options:
1. Kidney Intake
As there is plenty of airflow via one kidney and the bumper place some kind of scoop just behind the left kidney grill which will direct air into the mouth of the intake better.
2. Foglight mod
As front fog lights are not legally required in the UK replace this with an intake.
This would involve disassembling the fog light to make it into an air scoop. Then run a large diameter pipe into the bottom of the airbox. As the fogged airbox post this would be large diameter to stop water being actively sucked into the airbox and have a rodent mesh to stop things getting into the airbox.
You are confusing air velocity with air volume or, more importantly, the mass of oxygen you get into the engine since the rest of the air is superflous. I shall not go into the physics, but if you scoop the air in at high velocity the pressure will drop and therefore so shall the density and ultimately the mass of oxygen available. The opposite of what you want. This is why your car has been designed with the intake behind the headlight so that air is sucked in by the induction from the engine not pushed in by the flow of driving through the air. If you want to improve things you need a larger diameter intake collecting air that is as cool as possible and as still as possible. Take a look at some of the proprietry induction kits and then you'll have an idea of what you are trying to achieve. Before anyone asks, turbos and superchargers still draw air in from a still place but they compress the air increasing its density and therefore the mass of oxygen going into the engine it is not simply a case of pushing the air in quicker.
It works well on the M as that space down there also provides additional air flow to cool the brakes.
I need to do something on mine - with having the bodykit on the OEM scoop from the bottom of the bumper isnt there so mine just sucks up air from the bottom of the air filter which is not ideal (wasn't me that did it) but ultimately I need to make something that replicates the M solution
