Cut hood - Cold Air Intake

Manual Door for Adverse Weather Conditions
You might want to create a weather proof door for bad weather driving. You probably wouldn't be looking for extra performance during rain or snow anyway. The Pontiac Trans Am Shakers had a solenoid actuated "door" for this reason. It would probably be too complex in your situation to do this (unless you want to go into tapping the vacuum system or throttle linkage and engineering one), but a manual system might work for your needs.
This is an excerpt off of the High Performance Pontiac site re this subject:
"The '70 1/2 Firebird Trans Am shaker hood scoop was functional, allowing the engine to ingest cooler outside air via a throttle-actuated, solenoid-controlled "air valve" at the rear of the scoop. Dual solenoids were mounted on an internal bracket within the scoop housing using a small T-shaped rod extending to the air valve, which was basically a hinged door. The air valve was used to keep weather elements and foreign objects from entering the air cleaner assembly under normal conditions but for more spirited driving, specific throttle position caused the solenoids to energize, opening the air valve and allowing outside air into the air cleaner".

'nother idea
SBSS,
I picture a custom (handmade) fiber glass mold for a pourable ABS type plastic thingy that would be designed to mate right up to, and be attached, semi-permanently, the top of the engine air intake. It would look like a distorted funnel, with the small end at the intake. It would surround a K&N filter, probably mounted right on/to the air intake (separate bracket). The 'funnel' would go up to a compression gasket mounted on/under the scoop you made. As the hood is closed, the rubber squishy gasket would seal everything, (think I saw 'em on early Dodge Ram Induction system) and you would have a CAI built right in. If you don't prefect this idea (with some kinda 'rain- blocker' built in), I'll have to design it myself when I get my HHR.
Whadaya think???

A 12V damper motor (usually for HVAC applications) to operate a door might work if you have room under the hood. You may not be able to connect it directly to a shaft door, but possibly with an arm & linkage set-up, it might work. In this way, a door can be operated from a dash mounted switch.
It all depends on how far you want to take this.
This one is a balancing damper with electronic control, but I have seen them come in more simple offerings for residential bathrooms, boiler exhaust, greenhouses and tennis courts.

all it takes is a air deflector to " knock" the water/dirt out of the air stream but still allow the air to travel freely...used to do the same thing on dirt cars for the radiator( mud deflector)

I love the hood scoop thing and screaminblackss' look is sweet. I'd love to do what he did and have it be functional as well. It'd be nice if there were hoods out there aftermarket (even better with OEM matched paints!), but alas there ain't enough HHR SS' rolling around for most to invest into heavily. Anyway, watching this closely, it'd be nice to have a functional solution.

It's ok.
