In the end wouldnt we just call it functional...(the original question). even if its not that efficeint it works. Air goes through the scoop through the ducts and then there is room under the air box about the thickness of a finger where the air enters from the ducts (or whatever u want to call them) to go through the filter, lid, and so on. From my understanding that would constitute the hood as a functional ram air hood, and i would agree with Jimmard that it might not be cold air induction because the air passes over the engine which you would think would somewhat heat the air. phew...

Guess I was a bit short and non-specific or unclear . I was refering to the fact that it is, more or less, a functional cold air induction rather than a ram air. My car is black as well and I don't seem to have any detonation problems thus far and I do enjoy "running" my car. After a 30 minute drive home in crappy traffic on a hot afternoon, with a short 5 minute open drive to my house out of traffic at the end, I have opened my hood and of all things to be hot, it wasn't the hood or SLP lid; in fact the lid would feel cool to the touch. Maybe not all cars are created equal.

Eh who cares if it works or not. It looks badass . I'm sure the hood does something else GM would not have bothered with it. They aren't exactly cheap.

Direct from outside nostril, you can see the air filter. Zoomed in while holding a flashlight, took me awhile to set the brightness so I could see it hehe...


I plan on using something to block them off except for days I run the car.

True dat! It definitely looks badass...I love the looks of mine. Very very expensive for what it is though:

all your answers to your questions. from installuniverstiy.


Super Sport Hoods
Do they really supply cool air to the engine?

While doing some testing on a 1998 1LE SS Camaro I noticed that the intake air temperatures (IAT) acted strange. The temperatures were up and down throughout the test runs. It really did not hit me what was going on until middle ways through the testing.

The Super Sport hood directs air into the scoop on top of the hood where it then curves back around and heads toward the front of the hood where it makes another turn into the front of the air box assembly. There is a rubber seal that "seals", use that term lightly, the intake assembly so that it does not let any air from the engine compartment in. This is clearly meant to be a cold-air-induction setup. This is also a long distance for air to travel from the time it enters the hood scoop to when it makes it way into the air box.

The IATs were around 115 °F when we first started the testing. Once the car had been in motion for a mile or two the IATs dropped into the middle to low 90 °F. Wow! I knew that it just didn't get cooler outside all of a sudden! So what would cause this phenomenon to happen?

That gave me the perfect hypothesis that needed to be tested. While your car sits at idle the engine temperature rises. The hood soaks up the heat and can not dissipate the heat quick enough to stay cool. This causes the air that passes through the SS hood to soak up the heat from the hood. By the time the air gets to the air box you have heated air. Once the car goes into motion the hood is able to dissipate the heat to the outside air fast enough to lower the temperature of the hood. This would cause the air that enters the hood scoop not to heat up quite as much which would keep the air cooler.

We never expected to have such a lag in the time it took to get cool air into the engine once we started driving. The least amount of distance it would take the car to travel before getting cool air into the engine was one-half mile. Ouch! That is entirely too long, especially for us quarter milers.

Do your self a favor and get a ram air setup if you are looking to cool your intake temperatures down quicker than a half mile. Our fast toys ram air system gives us ambient intake temperatures from the time you start your car to the time you turn it off. It does a great job over the free ram air mod too. So it is a win-win situation to purchase a ram air kit if you really intend to get those temperatures down on the SS or Z28.

Z28 / SS - Pretty much the same ET/mph
Formula / Transam / Firehawk / WS6 - Pretty much the same ET/mph

Draw your own conclusions. I suppose it depends on your definition of "works."
There are holes for air to pass through, but they don't make "ram" anymore air
into the motor than a non ram air car.

What would happen if you made bigger the two rectangular holes on the back of the underside of the hood, where there air finally exits the "ram air" system? Would that allow more air in or would it just be a worthless mod?

Worthless IMO. "Ram Air" is really forced induction...which isn't happening
by allowing a little more cold air into the engine bay.

leave a bag of ice on the hood to keep the hood cool.

...as it would with non-ram air cars.

Do you think it would be as bad as mine tho? 150* IAT on a nice 75* day? I could understand in a normal car tho, I agree with you completely, maybe just not as bad as in my case.
