Here is a 2007-2009 Super Snake hood freshly received form SPP.....................



No ram air plenum at all behind the scoops for the "possibility" of making it functional...............



It still looks Cool!!

Guess I better not mess mine up if this is what i have to replace it with!

[dbackg]

that is correct. one must drill holes (4). approx 1.5".

The four 1.5" holes are for air flow/heat extraction function and will work with the heat extractor vents at the rear of the hood?

No plenum for ram air/CAI.

Robert, that is exactly what mine looks like that I just got back from SAI, I don't even see a spot you can begin to drill to make it functional??

I will take pictures today.

Is that Waldo sitting in the passenger seat??

That is a nice vette.

The only option that I can think of (if the rear of the scoop in not also the inside/underside wall of the hood itself) would be to cut the hood open in the rear of the scoop area, again assuming there is a gap between the rear portion of the scoop area and the inner panel of the hood, use the void above the radiator area in the front portion of the hood for air flow, and cut holes over on the side ahead of the air filter. This would use the void in the hood above the radiator in the frontal area of the hood to get fresh air to the CAI? If the rear portion of the scoop area is against the inner panel of the hood, then the flow would be of no real benefit compared to a large open plenum, but you could say that the hood does function.

This is the method I mentioned to "possibly" make the 2010-up hood functional, but I have no hood here to closely examine.

This void in the hood, above the radiator would also include the hole where the hood latch fits, so that would be a place for ram air to escape, unless it was sealed.

Ok, so it is more of the function I outlined in post #5, fresh air inlets for heat extraction air flow more than directed/channeled air flow directly to the CAI as the ram air plenum previously provided.

Correct.

The pictures in post #1 is a raw SAI Super Snake 4th generation hood that is NOT finished.

I don't understand why the exterior ram air scoop "opening" is closed up.

I usually shy away from posting in here cause I'm not as familiar with the GT500 but I do remember stalling issues with the early SS hoods due to the flow of air into the CAI. I remember they added baffles but that there were still issues as, and this is getting over my skis, the car is tuned to the typical amount of air-flow and even with the baffles the large degree of change wasn't something a fixed tune could handle.  I wonder then if SA just decided to forget the whole thing?  CAI isn't a "ram air" system and forcing air into it just isn't a good idea.  

This is all from memory and I could be totally FOS!

My guess is that since the hood opening no longer has the plenum for fresh air, and there is no option of opening it to make a fresh air function, they keep it closed because most owners would not want rain water entering through the scoops? <<This being an issue that has to be considered on any of these hoods that are open.

Notice I changed it from ram air, to fresh air. The outside air being fresh/cooler than the underhood heated air.

I still have had no issues with drivablity on my 2008 Super Snake, built early (Jan./Feb.) 2009.
