Help with RAM air

[540dude]

I just picked up a WS6 but had a few questions...

First off, it has no hood scoop and the mass air is covered by a plastic case.
How does air get into the RAM air if I have no hood scoop and there is a case over it?

Are you referring to the air filter? If so, the majority of the air enters from below. Removing the lid will allow axcess to the filter, and you can see the air channels. As for the hood scoop, all WS.6's had ram air hoods. Unless the hood has been replaced. Are you sure it's a true WS.6? Check the RPO codes on the driver's door jamb sticker. WS6 should be listed.

I was thinking the same thing. Check your RPO code sticker, it should be on the driver's door. As previously started, WS6 should be one of the codes listed. If the sticker is missing, there is a place on this site to have your VIN checked to see what options it came with. Do you have a pic of the hood?

What do you mean it doesn't have a hood scoop? Pictures would be helpful...

I suppose if it doesn't have a hood scoop it's not a ws6, that's just what I was told.
How does the air intake work? I'm not used to this, it's just a box that connects straight to the engine? I'm used to long RAM with the filters at the bottom of the tubing.

As I recall, air enters the scoop on the hood and is directed through the hood to the front side of the filter, on the bottom. I've never owned a SS or WS6, so I can't quite remember. You need to look on the sticker on the driver door for the RPO codes, that will tell you whether or not the car is a WS6.

This is what a stock WS.6 airbox looks like. The large plastic piece behind the airbox is called a helmholtz resonator.

is the helmholtz resonator a noise resistor?

[pajeff02]

Cuts down on noise and cancels standing waves in the incoming air.

Referring to the picture in pajeff02's post, air that makes it through the WS6 "nostrils" on the outside of the hood passes over and under baffles in the hood that seperate rain water from the air and passes out the hood through a slot on the underside. When the hood is closed, this slot lines up with the wide slot at the front of the airbox under the 2 metal clips shown in the picture, which is where air flows into the bottom side of the rectangular filter, out the top and into the large rectangular "air lid" (that has the "Ram Air" decal on it in the picture). This lid then guides the air rearward through those aforementioned chambers (helmholtz resonator??), through a rubber flex coupling to the MAF (mass air flow sensor), then past the TB (throttle body) into the intake manifold (the big black octopus).

If the car is NOT a WS6, air gets to the front of the airbox from under the front bumper (in front of the radiator) then enters the filter from below through a narrower slot. Only a WS6 will have the "raised airbox" with the taller slot (as pictured) for air to enter the filter. Otherwise airflow is the same for all LS1 f-bodies.

So does the slp lid provide better air flow?

^^^Yes.

It eliminates the hemholtz chambers/flow restrictors. Any quality lid will do that. Proven 5-10 HP upgrade.

+1. If you compare an aftermarket lid to the stock piece, you will see quite a bit of difference.
