Default Intercooler for CAI

Guys,

I was toying with the idea of creating an CAI with an intercooler connected after the filter. i have a green cotton wind filter and an intercooler from a indica vista to be fitted on a lancer, your suggestions please.

The compressed air which passes through the inter-cooler in a turbocharged vehicle is pretty hot & the air flowing through the inter-cooler helps reducing its temperature. In your case (NA car with inter-cooler in between air filter & throttle body) - the temperature of air flowing through the inter-cooler will be almost equal to that of the air blowing over the inter-cooler & hence wont help. You will actually end up loosing power because of bad Air Intake system.

Exactly, this is how it works

this is not correct, technically it should work in the absence of turbo as well. As per you what should stop it from reducing the temperature of the air sucked through it.

The air passing through the inter-cooler & the air blowing over the inter-cooler when of the same temperature wont make a noticeable difference to each other. Even if you succeed in blowing air over the inter-cooler which is a lot more cooler than the air flowing through the inter-cooler, the air intake dynamics will be so disturbed that you will still end up loosing power.

Again, The air blowing through the intercooler will be cold as the surface area is larger due to the fin design of the intercooler. it will any how decipate heat and become colder, by theory we can also design to spray a jet of of water to cool it off substantially.

Ok, even if you reduce the air intake temperature using a inter-cooler & water spraying it,etc how much power is it going to bump up ? 1 bhp ? And i still say you will end up loosing power because of the bad air flow dynamics.Remember in a turbocharged car with an inter-cooler the air is force fed. For a NA car with a inter-cooler it will be so difficult for her to breath.

Agree with you Neil...

Simple terms: Air velocity drop due to the obstructing intercooler in the path of the induction system will affect the performance at medium to high rpms severely. Remember in an NA engine the air sucked in a co-relative to the suction quotient of the piston inside the cylinder where as in a turbo charged engine its directly proportional to the boost pressure which can be higher than 1bar (14.5psi) which is our atmospheric pressure at sea level.

Pramod, if this technique you are contemplating could give out more power or efficiency in an NA car trust that we would've already seen it in several dozen cars. Keep your thinking cap on, may be you will find a better way of extracting residual gains...that something which has never been tried

Don't do it.
It will cause too much of a restriction and will adversely affect performance...

Some website had referred to an inter cooler setup without a turbo as an inter fooler.

Inter-cooler in the intake of a naturally aspirated car = restriction to air flow. So technically also it will not work, unless you put a blower to charge the air flow

CAI = Cold Air Intake, and you still want an intercooler?

Intercooler is used in Forced induction systems, do not fit it just because you have one lying around.

you will essentially be blocking the airflow to the engine by putting an inter cooler without a turbo.

I im the same lines, Intercooler will only give some additional pressure drop which you dont want to happen.

Ok guys,

Plan shelved as of now, i will hold it till i get a suitable turbo to go with it.

Mods, kindly lock the thread, i will intimate you whan it needs to be reopened for discussions.
