Would there be anything wrong/unsafe with fabricating a custom Ram Air system to go along with my CAI?

As it is right now my filter just sits where the air box used to be. I am going to run some rubber tubing down past this area and remove the vent in the air dam. That way I will get a LOT more air to my intake. I am going to put a screen there so that I'm not just taking in anything.

Think there would be anything wrong with that?

 

Most CAI's put the filter down in the fender, outside the engine compartment, and isolated from the engine compartment with a block-off plate. What vent is there in the air dam to remove?

 

So you have something like this?

 

i don't think he does. What year you got? becuase on my 1999 the K&N sits right where the old air box was. It sits directly above the radiator, almost touching the hood when closed this is wat it looks like http://www.fquick.com/garages/viewga...wimg&id=130298 this is my car, its a v6 but the intake should look the same on a 98-02 ls1

 

He has a 96, it will be different.



I'm thinking he has something like the picture I posted (which the previous owner of my car claimed was a cold air intake, when really it's a filter replacing the air box), but he wants to put a real CAI (Extend it past the engine bay) and remove something from the front to allow more air to reach the CAI. When the previous owner did the LS1 Front End swap on my car, he didn't put in the fog lights. My CAI Filter sits right behind that hole. I think he's looking for something like that.

Although you are kind of forcing air into the CAI, It isn't at all the same thing as Ram Air. Ram Air completely replaces a Cold Air Intake; you can't use them together.

 

my bad forgot to look to see what year he was. does that mean mine is a ram air?

 

V6's didn't come with a ram air option, so unless you added it yourself, it is not.

I can't see your picture though, so I couldn't tell you.

I can never tell what kind of air intake LS1's have; the stock, cold air, and ram air all look the same to me. But I've never really took the time to look. Maybe someone could help me out with this.

 

yah i put an after market intake on and i think it may be a ram air because its sits right where the ss ram air hood opening would be

 

You have a filter sitting on the radiator cover. Its not Ram Air, unless it is fed through the hood by outside air, and sealed to the hood to prevent loss of the pressure developed through the principle of "velocity head".

This is a 93-97 setup (a bit different than the 98-02 version):

The hood has openings right in front of the airbox, and there are flexible seals on the hood to seal it to the airbox.

 

o ok now i get it thanks

 

In front of the wheel-well...kind of below the turn signal. There is a slotted vent. That is the one I'm talking about.

Mine looks like that.


The way mine was set up, the filter was just sitting where the old air box took in air. I guess I don't know if that is how a CAI is supposed to be, but I want to change it. I don't think it's getting as much air as it could.

So this is what I'm doing.

I'm going to run a rubber elbow from the air collector(the plastic box the hooks to the mass-airflow sensor)
Then my filter will sit in the hole where the stock box was.
Then I'm going to run plastic tubing from the filter to the vent under the front bumper. I will prolly put a blocker plate so that the tubing has a place to fit into.
And then I will put a screen in that tube. To keep out bugs and stuff.

I should have took my pictures to go along with my explanation... It's not really Ram Air I suppose. But I want to force feed air to my filter.

When I finish it...I will take some pictures and post them.

 

The engine creates a vacuum. Ram air sounds good in theory but does it even really work untill you get up to a pretty high speed?

 

Yes, there is such a thing as "Ram Air". But it takes a lot of MPH to make an appreciable difference. It can be shown that the ram air effect, when evaluated using the concept of velocity head, can produce a maximum gain of about 1% at 100MPH. So, a 300HP engine might see 3HP, with the correct configuration of the inlet. But don't forget, in addition to the "ram air" effect, you are picking up cooler air, and running it through a much shorter, more direct flow path with the LT1/WS6 configuration, so the gains may be more.

Since the pressure gain due to velocity head is proportional to the square of the speed, you would see less than 1HP on that same engine at 50MPH, and about 6HP gain at 142MPH.

 

Well all the same...More air can help fuel economy. Right? Because that would be pretty helpful right now. :Stupid Gas:
