is it worth it to intercool a na car? i would think based on my limited knowlage it would be due to further cooling of the air already coming from the cai... the reason i ask is there are the side mounts from the gsx eclipse and vr4 i thought you might be able to run some plumbing to and do it? just a thought .....

 

did you really just double post this?

 

There is really no point. The reason an intercooler is there is because a turbo(requiring an intercooler unless you're running methanol) spools via expanding exhaust gases(HOT!!). A N/A car takes air in from a filter element only. That air is already as cool as air coming from a turbo through an intercooler. Basically, an intercooler will not cause the incoming air to be any colder than from that of a CAI. It's not a fridge, unless you use an Nterchiller kit.

 

your kidding me right?

 

That's what I thought, but then I went ahead and wasted my time explaining it.

 

they do sell some pretty gay front mount intakes.

 

just run your CAI pipe up through the stock airbox and pack the airbox with ice

 

The main air temp increase from a turbo doesn't come from exhaust gases. The exhaust gas is on the opposite side of the air intake. Although a little heat will travel through the center cartridge to the intake side, the air being compressed is what causes the main temp increase.

 

Don't be mean. I had the same thought the other day. I'm new to FI and wasn't sure if it would make a difference either but researched and found it to be a waste of time. However, if you could find a way to cool the air further at the point of entry to your CAI there may be some gain. How you do that though is beyond me right now.

 

I don't know how well they work but here you go...

****, might as well just buy a motorcycle N20 kit and run that (usually a 30 shot). More gains, same price.

 

Nah, the turbo'ed air is hot because it has been put under pressure. Air heats up when it is under pressure. A supercharger releases hot air as well.
An intercooler just transfers the heat from the forced air inside it to the outside air coming through it. So there is no way for the intercooler to cool the air MORE than the outside air.

 

You could run some really elaborate air piping, put another coil on your R-134a line, then run your intake air through that. It'd take care of any humidity problems, too.

Please, please don't take me seriously and actually try this.

 

Pressure times Volume divided by Temperature at the start of a compression cycle is equal to the pressure times the volume divided by the temperature at the end of it. Volume stays the same through the turbo but pressure increases. Therefore temperature must increase.

The second stage is the intercooler. Temperature decreases while pressure stays the same. Therefore volume must increase which makes for a better air fuel ratio better.

I knew physics would come in handy some day.....

 

Lets say you are running no turbo (14.7 psi @ sea level / 101.3 kPa) w/ a 2.4L ralliart engine. This means the temp going into your engine would be the same as the outside air, lets say a balmy 80F ( 299.8 K). Now bump the turbo up to 6psi; now the pressure is 20.7 psi (142.7 kPa), still w/ 2.4L. so now some physics...

(101.3 kPa * 2.4L) / 299.8 K = (142.7 kPa * 2.4L) / x K

solve for x

x = 422.3 K = 300.47 F

End result, a not so balmy 300F
