Having them electronically controlled by a switch or the key is a cool custom feature as well.

I don't think there are issues with driving in the rain - not much in the way of water should really find its way in enough to soak the air filter (I'm guessing) aside from someone splashing the hood with a small pond-sized puddle or something like that.  The air cleaner should have some drainage, I believe.

Yeah, the plenum has the drain holes for water.

As a kid I remember watching Speed Racer's Mach 5 with all the buttons in the steering wheel hub. That's the goal, but I still have a lot of work ahead of me to make them all work whistling. The next button is "B".

There were 8 buttons in the hub.

Button A, Auto Jack: Releases four jacks to boost the car up so that it can be repaired. Although designed for this function, the auto jacks are more often used to jump the car short distances, as a wedge to keep the car from toppling over a waterfall, or as an alternative braking system. The spring-like sound the jacks make is distinctive to the show.
Button B, Belt Tires: Sprouts special grip tires for traction over any kind of terrain (firm, icy, or unsteady ground; ocean floor; vertical mountainsides). At the same time, 5,000 horsepower (3,700 kW) is distributed evenly to all four wheels (1,250 hp/932.13 kW).
Button C, Cutter Blades: Powerful rotary saws protrude from the front of the Mach Five to remove obstacles in its way such as trees. Mostly used for racing in forest areas (especially when Speed gets forced off the road).
Button D, Deflector: Releases a powerful deflector which seals the cockpit in a bullet-proof and crash-proof, and either an air-tight or water-tight chamber depending on the environment around the car. Inside it, the car driver is completely invulnerable.
Button E, Evening or Illuminating Eye or Special Illumination: The control for special illumination which can be traversed singly or in tandem, and which enables to see much farther and more clearly than with ordinary headlights.
Button F, Frogger Mode: Used when the Mach Five is under water. First, the cockpit is supplied with oxygen. Then, a periscope is raised to scan the surface of the water. Everything that is seen is relayed down to the driver's seat by television. The 100-pound (45 kg) auxiliary supply of oxygen is enough to last for thirty minutes.
Button G, Go Homing Robot: Releases a homing robot bird from the front of the car. The homing robot bird can fly and can carry pictures or tape recorded messages, handwritten messages, X-ray film, rope, and small Egyptian statues, and it has been used as a last resort as a makeshift weapon for means of defense. The bird-like device is operated by a built-in remote control within the cockpit.
Button H, Homing Deviceg): This button is, unlike the other buttons, not located on the steering wheel; instead is located on a console between the seats. Button H is part of the Go Homing Robot's controls, and it simply sends the robot "home” to a pre-programmed location, usually Speed's house.

I'm not sure that Ford ever rated the Ram-Air cars as having any more horsepower over the non-such equipped Mustangs. It's likely that any improvement came more from cooler,denser air being introduced, rather than being "rammed"in…..just my observation. However, back when "Musclecars" were first being marketed, the manufacturers knew that hood scoops sold "street-cred", along with stripes, spoilers, wings, flashy colors, white-lettered tires, etc. What the hell, would we have it any other way?

Spike, all the manufacturers were playing so many games with the horsepower numbers, it was hard to believe any numbers you were given then. A 428 CJ with 427 heads and a truck load of performance parts rated at the same 335 HP as a 390 GT!? Same with the Boss 429 with heads the size of Kansas and rated at the same level as a 429 CJ/SCJ!

I was always told the optimal location for a hood scoop was at the high pressure areas which are at the front leading edge of the hood (71-72 GTO, 68 GT500 Shelby, 67 427 Fairlane) or at the cowl area much like you saw on the cowl induction Camaros and Chevelles to name a few. And as David can testify, during the carburetor days, the air cleaners on the Nascar engines were  constructed to draw air from the area just in front of the windshield.

Like you stated the biggest gain is more than likely from the cooler denser air being drawn in rather than any ram air effect unless running over the other side of 150MPH!   whistling

Like you said, the "Street-Cred" rules in the 60's and 70's dicated that you have the look. Even if your car wouldn't  run over a 100 MPH if it fell off a cliff, it still needed that look. The hood scoops, stripes, spoilers, N-50 tires (remember those), thrush mufflers, and plenty of Keystone and Cragar wheels, it was a rite of passage. 

I always loved the look of the Shaker ram air system, but the 71-73 NASA hood seemed to have the best integrated look. Seemed like a lot of the hot rods (factory and back yard built)  had that "I Just Came From KMart" appearance!!

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!
