Intercooled w/o turbo????

I've always had this question of whether it is possible and benificial to put an Intercooler on a N/A car (i.e. no turbo). Does it help either on the performance end or cause less wear and tear on the engine, as it is running cooler? Help out a nonmechanically inclined (when it comes to engines anyway) noob.

Sure it's possible, but it isn't beneficial. With a cold air intake, the air going through the intake tract is as cool as the air going over the intercooler. Just doesn't do anything. Having a bit more plenum space might help your throttle response and low end a bit I suppose.

The only reason an intercooler works on a turbo engine is because when you compress air, it gets hot. So if you never compress the air it never gets hot. Therefore an intercooler would offer no benefit to a NA car.

From high school physics PV=nRT i believe that is called the universal gas law
P=pressure
V=Volume
n=number (moles, number of molecules of gas)
R=constant (avagadro's is it? i dont remember)
T=Temp.

Pretty close. R is the universal gas constant. R=0.08206 L*atm/K*mol. Avogadro's law states that volume of a body of gas, at constant temperature and pressure, has a volume proportional to the number of molecules present. Avagadro's number is nA, and I forget what it is exactly because I'm an engineer, I use a calculator for that kind of thing, and it's at the office.
