N/A Intercooler

So I had an idea the other day...If you don't want to dish out the money for a turbo kit atm and are looking for just a little more performance as well as better gas mileage why not just jimmy rig an intercooler to your intake? Now THAT is a cold air intake.

What do you guys think about the idea?

Sorry to be the first to nay you, but as nice and deceiveing as it may look, all the bends and distance the air travels would hurt you in the long run; you can get a good CAI n it'll so a better job....IMO

As far as the mileage I wouldnt be too sure , but good luck on ur decision.

Yea I had the same idea a loooooooooooong time ago but it won't work, theres too many bends like he said and you won't be seeing any useful benefits

That sucks. I thought it would be a nice addition to an all motor car. Oh well.

an IC is needed because the exhaust gasses can signifigantly heat up the air going into the intake from heat soak at turbo. warm air is less dense and burns less fuel per volume of air.
An IC adds nothing to a car if the intake is allready at ambient temperature.

I may be wrong but the only way i can see that might work, is if you had nos mounted to the intercooler. I could be dead wrong though

^^^^ this

Intercoolers go inbetween a compressor and the throttle body... anything else is rice.

while heat soak adding heat is true characteristic of a turbo system, the thing that really adds the majority of the heat to the air is the pressure change, basically adding an intercooler to a NA car and getting a significant temperature drop will break the rules of thermodynamics.

What do you guys think about the idea?
It may cool the air going in to the intake but not enough pressure so their is a restriction. You may be better off heat wrapping the exhaust manifold and catylitic-converter. Just my two cents.

Yes your right! As an engineer I'm a little ashamed of myself!!
pV=MRT
P=Pressure
V=Volume
M=Mass
R=gas constant
T=Temp

If you raise the pressure on the left side of the equation with volume being constant (which we know it is) then the Mass or Temp or both on the right side of the eq must increase to keep the equation balanced.
Mass is fixed in a way by the mass flow rate. The same amount of mass must be entering the system as is leaving.
This leaves a temp increase as the only way to keep the equation balanced.

It's been a few years since college but if I botched this fundamental thermodynamic equation someone just shoot me know, or I mean let me know.

//EDIT
Now I got to thinking about this and when you cool the air down with the IC you are messing with the equation all over again. I screwed up somewhere!! Must be that this is a static equation and we are dealing with a dynamic situation
END EDIT//
