I know the SS hood scoop on the LS1 Camaros is pretty much junk because the air has to snake around, and it can become heat soaked.

Now did the SS scoop on the LT1 cars actually get fresh, cool air to the engine in an unrestricted manner?

 

yes

it was literally a ram air...the filter sat right where the hole in the hood was

 

It works just like any other induction system having an exposed filter. The efficiency is based on the amount of restriction due to the routing. The LT1SS is also somewhat restricted (the pontiacs have more of a straight shot) but none of the systems are "ram". JMHO

 

Here are some pics of my LT1 hood i modified for direct Ram-Air. It's an SLP hood. It's much more efficient than the LS1 hoods.

The hood took a deer at 75mph, so thats why i decided to modify it. There used to be a water trap, which was a piece of fiberglass directly in front of the opening which directed the air down, then back up to the filter. i removed this so the air would go directly to the filter. I have heard of atleast 5 people who have done this and had no problems. I havent heard of any problems from the water getting in it from the rain or anything. I also removed the divider and made the hole bigger. i saw this being a much more efficient design for our hoods.

 

The LS1 hood makes the air do a twisty inside the hood, the LT1 ram air does a twisty in the intake piping, though it IS better then the LS1 ss setup for sure.

 

How does it do a twisty?

 

Goes in the box, down from the box towards the front of the car, then 180 degrees into the intake.

 

All you have to do is turn your motor around in the engine bay, then the air will be true ram air. Just swap what side of the car your pedals and steering wheel are on and put an extra swivel on your driveshaft. Presto chango! Ram air baby

The Ram Air H.O. and the Ultra Z didnt do this did they? Here is a pic of the 1996 WS6 hood i have that i removed the water trap.

The air box sits directly behind that.

Actually in the stock LT1 SS hood the air has to travel a full 360* to enter the engine.
It starts at the hood intake opening which is slightly aft and above the TB. It then moves aft through the internal hood baffling to the filter. It then travels down and to the left(driver side), then forward, then back to the right through the MAF, then another right flowing aft to the TB.
This doesn't sound like it would be much better than the stock Z28 intake, however the tubing is smooth and mostly round with no restrictions. The air is from ~3 to 3.5 feet above the surface of the road and so is at ambient temps. Most will agree it's a fairly good CAI, but has no ram effect.

 

The ram effect probably would not come into play until higher speeds. I think at very high speeds, the ramming pressure of the incoming air would overcome the effect of the crappy air routing after the filter.

Just my thoughts, I have no scientific data to base this on.

My hood isn't like that, and neither are the Ultra Z's. Why not go that route? There was no bending intake rought, just a straight through design.

 

You are correct, but (and there's always a but) air is generally considered incompressable (the density does not increase) until you reach 150 m/sec. or about 335 mph. Below this it is unlikely that you could get enough density change to require even one jet size increase.
And there's one more problem. The scoop (stock SS hood) is at one of the lowest pressure area's on the car. The only place worst would be about a third of the way back on the top. For a scoop to gain any effect it has to be at least 1 1/2 to 2" above the hood line. You see ram air scoop like this all the time at the drag strip.
