I've wondered that myself.

how does the C6 breath?
The air that enters through the front grill seems to all get directed into the radiator as the sides are sealed off. Also what are the plastic pieces covering (located right behind the grill) to the sides of the radiator. Halltech makes a shroud with screened ports (where the plastic pieces are) to allow air to enter to the filter. So back to the initial question where does the C6 draw its air from in its factory configuration?

Well wherever it draws from it's much better then the stock intake on the GTO! With the GTO the plastic airbridge would always be hot to the touch. The other day I put a hand on my Halltech and the bridge was nice and cold after a drive.

If you stick your fingers through the grille and poke at the blank plastic sheets on either side of the radiator opening, you will find that they are open at the top, and bleed air into the compartment above the radiator feed where the aircleaners live. Also, from underneath the car, there are a pair of fairly large openings (about 6" square each) at the bottom, behind those blank black plastic pieces, that allow air flowing under the car to flow up into the air cleaner space. All of these taken together DO feed enough air to the aircleaners to allow the engine to make 400 SAE net horsepower.

There can't be much cool air reaching the stock filters, every brand of CAI seems to give around 15 RWHP on the dyno, probably more in a real world airflow situation.

I'm talking about the true Cold Air Intakes, not the filter or air box mods. If it draws fresh air from the grille opening it's a CAI, anything else is still using warmed air thats been thru the radiator and around the motor. My Lingenfelter CAI gave as much peak HP as the LT headers. Dyno'd with cat back @ 350/346, with headers @ 365/362, with CAI @ 379/371.
I wish there was some way of simulating the airflow to the intake @ 145MPH in 4th, fans on a dyno can't come close.

Ah yes, data trumps opinion every time. Thanx for your contribution.

A Temporal Anomaly ? ? ? ? ?
Is the CF having a "clock" problem?
My reply to Brett Hunter's post really was made at about 2:21 pm EST today, but his is time-stamped 2:29 pm, so my reply is ABOVE his post

Is today the day the the earth's magnetic field is flipping the North and South poles, or is there some other explanation for this temporal anomaly ? ? ? ? (Captain Picard - the sensors are acting strangely . . .)

If anyone has data to prove otherwise please post it. I have ask for data proving the bottom breathers lower the IAT in several threads over the years and I have never received a response. Most of these threads had the manufactures responded in them but my question always is ignored. Like I stated earlier I have limited logs of a bottom breather so I am relying on others to show the benefit as far as IAT is concerned.
As you can see from the below chart the IAT does get within 3 degrees of ambient at 70 mph with the stock filter. BTW ambient was 65 degrees and the lowest recorded IAT was 68 on this run. This is probably a worst case scenario for the stock setup since prior to this scan there were 8 WOT runs over an hour long scan. So this shows the stock setup after over 1 1/2 hours of running with the first hour being very hard driving.

It just keeps moving it to the bottom.

If you were to cut your shroud ala Halltech, and view from the front, you would see clear space to the firewall.
The open shroud will allow added outside air into the filter area, but it's not as if it were entering a sealed plenum !

I don't think that the air path is really that restrictive, when you put the car on a lift and examine it from below.

Clevite, If you asked the Corvette engineers at the Corvette Corral about the intake system that would be great. Im sure however you will be so excited to be there you will forget.

Great post CleviteKid thank you. Why do you think GM made the intake system so restrictive, for emissions? Those plastic pieces IMO should definitely not be there. I have the Halltech Stinger SSM (LOVE IT!) and will be purchasing the Halltech Cold Air Induction to shoot some fresh cool air right to the filter. I will have to ask Jim Hall about the programming as its suggested after installing the CAI but not with the Stinger alone.
