Where are y'all getting a ls7 5th gen from? All I've heard gm releasing in the LSA...
And as far as Gen V motors, to think that GM would spend hundreds of millions designing an all new motor in the times we live in and would not include DI from the start is smoking crack.

It doesn't?
I thought that underneath the hood there was flat tubing/runners going forward and around from that NACA duct scoop going right into the airbox just like on a WS6 (though obviously far less useful/efficient than a WS6's 'straight shot' ram air)?
Minimal power gains (if any) no doubt but I do believe on a factory 4th gen SS hood that air from the scoop does feed into the airbox.

I don't know about the LS1 SS's, never had a chance to examine them, but my LS1 WS6 ram air does feed the airbox. I don't know that it makes an appreciable gain in power (an LS1 is an LS1), but the air flowing into the scoops is ducted to the airbox.

Yeah I think there is a misunderstanding here. The LS1 SS/WS6 BOTH have setups that DO feed the airbox. The WS6 has a straight through design, where the air that enters the nostrils passes straight into the airbox opening. The SS has reroute ducts that circle the air back to the front of the airbox. So, the simple answer is YES, both those cars do have functional "Ram Air". I will admit though, it's unlikely that there's really even any drop in negative pressure at the airbox thanks to these setups...more than likely they are about equivalent to a standard CAI (cone filter) setup.

There are plenty of reasons to name the "top dog" Camaro a Z/28. They were the top model Camaro for more years than the SS. The 1st gen Z/28 and SS had completely different missions - the SS was more a street car, while the Z/28 was a harder-edged "race car" for the street. The most powerful SS396 only ran a tenth or two quicker in the 1/4 mile than the Z/28, and the Z/28 would absolutely slaughter the SS396 on a road course. When they decided to use the SS name on the 4th gens, it was only because it was a recognized name from the brand's past, not because it was more special than the Z/28. Also, the Corvette uses "Z" designations for its top-level models (Z51, Z06, ZR1).
And lastly, any Chevy can be an SS. Only a Camaro can be a Z/28.

LT1= true ram air
LS1= fake ram air (for marketing purposes)
Don't believe me? here's some pics of an LT1 WS6 vs LS1 WS6 intake systems:
LT1
LS1
Care to explain how the air coming in from the nostrils breaks through the lid into the air intake tract? It can't and it doesn't. You can obviously see where the LT1 gets its air from, the hood nostrils.
Here is my post from the other day about the LS1 vs LT1 functional ram air hoods, with pics as well:

EVERY LS1, no matter if it's a Camaro, Trans Am, Formula, Firehawk, SS, WS6, Z28, whatever, breathes from below.

In addition, the scoop designs sit far too low on the hood on the car. The hood scoop equipped vehicles have been proven to be no faster at the track!
That's the kit for LS1 cars, and they don't have a kit for the LT1 Ram Air cars... I think that tells you all you really need to know.

I do happen to have owned these cars and can assure you that air does pass from outside, through the hood, and into the airbox. There is very little space between the radiator and support shroud for air to pass into the airbox from underneath...so most of it actually gets into the airbox through the front opening.

I find it very hard to believe that is anything close to efficient. I have never thought that it could draw any air in there, it just kind of floats around and might getting sucked in. Definitely not forced in like a true ram air.
Irunelevens' post sums it up pretty well.

I guarantee you that the LT1 "ram air" offers no more gain than the LS1 "ram air"...which is to say, they both offer NONE. Both cars get their air through the hood one way or another...but as mentioned before, it's probably about the same as using a cone filter CAI instead of a closed factory airbox.

if its the thread im thinking. the consensus was that for a 4th gen camaro, it would produce a ram air effect as defined at 330mph. the ws6 a lot sooner.
