How much HP will a cold air intake boost you?

[BigBoizGS]

Yea i was just curious on about how muhc HP a cold air intake will give you. Im makeing my own im good with bening metal and stuff and know where to run it for the cone. so im just curious whatr the HP could be. Thankz

Cold air box mod: http://www.sounddomain.com/id/welnas

My web page shows a cold air box I made for my car. Page 7 shows how I opened up the area under the filter to allow outside air to come by the filter. Just throwing this out for anyone interested.

(and yes, i know this has nothing to do with N/T)

Of course it doesn't. When you start driving, the air in the intake pipe cools down. However, this has NOTHING to do with wind chill.

When the car is stopped, the temperature at the filter, and therefore in the intake pipe at the air temp sensor, will rise due to underhood heat. As you start to move, airflow through the engine bay increases, and the intake air cools down.

The cooler temps have nothing at all to do with windchill. It's just a circulation thing.

This is exactly what has been done.

No it has not, unless your intake pipe is physically isolated from the engine bay and turbo (it's not) and the inlet is located at least a couple feet from the car (it's not).

Ok good we agree then.

When the car is stopped, the temperature at the filter, and therefore in the intake pipe at the air temp sensor, will rise due to underhood heat.

My air filter is in a location where it is not subjected to under hood temps. Even at idle air is moving through the intake at a rate faster then under hood heat can charge the air passing through the inlet tube. Similar to moving your hand quickly over a match.

To each his own.

Liquid Illusion:
Just to clear something up, is the temp at the probe ( the one in the intake tube ) reading lower temps than ambient air temps? I think what kpt4321 is saying is that you cannot have the air get colder than ambient.

No, we do not. You said that this was because of "windchill" which it is not. Windchill, first of all, is a term that describes a "feeling" humans have when subjected to moving air cooler than their body temp.

The temp drops simply because you are getting fresher, cooler air.

My air filter is in a location where it is not subjected to under hood temps. Even at idle air is moving through the intake at a rate faster then under hood heat can charge the air passing through the inlet tube. Similar to moving your hand quickly over a match.

Like Groomz said: Watch the intake temp with reference to ambient temperature. The intake temp will never go below ambient, that is not possible.

Therefore, when the air temperature rises when the car is stopped, something obviously has to be heating it up. That something is your car.

i dont have a intake but i did have a cold air on my other car (92honda accord) an i can honestly say it made a difference in throttle response an acceleration

Apples and oranges are the same ? Hondas and Mitsubishi's are two different beasts

tru just adding my 2cents

Strange...last I heard they both ran combustion engines. :shrug:

You should consider posting a "how to" in the tech articles when you decide to install the CAI. I know on my car there isnt much room for any cold air setup but im interested to see what you come up with.
