Does anyone think it would be possible to make a functional ram air hood?
I was looking around my engine bay the other day, and it looks like it wouldn't be possible due to the location of the air intake.
The hood inlet would have to be off to the right, and that would just look dumb I think.

I won't be getting a ram air hood if it isn't functional...

I am sure its possible, but it may not look the best. Someone will have to fabricate an airbox to mount ontop of the motor and loop the hoses around to the throttlebody. A functional hood would probably have to look similar to an SRT-4 hood with a scoop similar to that, but the biggest problem is to get a box with enough clearance to clear the hood.

Depends on the car. It would almost be useless for the SS S/C. There really is no such thing as ram-air for a forced induction car. The best it would do is cool the engine which is not a bad idea either.

The other trims of the Cobalt might benefit better with ram air if you relocate the airbox.. or could mount the scoop directly over it making for an offset hood scoop.

The duct work hopefully could be molded into the hood itself, with a rubber to rubber
contact area between the duct work and the throttle body.
I agree there's not much you'll get from this on a supercharged car but I would rather grab air from outside the car as opposed to the fender well!!!
And if it can be forced, better yet.
I think a cowl hood would look perefect and could be molded high enough to include the duct work. What do you guys think???

I really like the look of the hood on the Cobalt 272 concept car. I hope that GM or an aftermarket company will produce that hood. In the Vehicle Highlights it lists the hood as being functional but not a Ram air hood. Is this similar to what you are looking for?

How well do they work in driving rain ? Functional Ram Scoop hoods that is.

BTW RK Sport has a functional hood. But that might be function with the 2.2 eco and not the SS/SC.

Why don't you call em up and ask them and let us know

The WRX's scoop goes to it's intercooler, not airbox as some beleive. I think that's a really good idea. Perhaps it has an application on the non SS Cobalts with turbo kits (2.2L,2.4L..).

Except your intercooler on the WRX sit on top of a hot engine. And heat rises. I think most WRX owners who do a lot of work on their car make a front mount intercooler one of the items to upgrade. I think the top/hood mounted intercool looks cool and keeps the intercooler safe from rocks/road hazards (rally heritage)

The ram air hood I had for my Cav had a duct that dropped into the air box that held the air filter. This was a RK Sport hood. It's a pretty basic design. I don't see why you could not do the same thing for the SS. All you have to do is design a box that would be mounted in front of the supercharger, then run a duct over to it from the hood scoop, and have rubber seals on the box and duct. I'm sure this is what Chevy did on the 272. You will not see much performance gains at lower speeds, but at higher speeds you will be ramming the air into the supercharger, possibly increasing the boost. I just wonder if the intercooler can handle the increased heat load. As for driving in the rain.... I had never had a problen in the rain with this type of design. If a problem arises, all you have to do is put a hole in the intake box to drain any water.

What about the filter getting wet?

redrocket

The cowl hood I mentioned would take air from the high pressure area in front of the window, it's not a ram type hood. I think this type would look really good on the SS. However I'm not picky and would be happy to get air pretty much from anywhere as long as it's outside the car.

Actually, in the real WRX's, there's a button in the cockpit to spray water directly on to the intercooler... that's why they put it there.

Then again... who actually has a real rally WRX anyways, right?

IceRacer

I think you'd have to do something like this:

except putting the intake opening on the other side. It would be more like a CAI/Ram Air combo. Might look a little wierd on a Cobalt though.

swatthefly

dont worry about the filter getting wet. you can use water to clean the filter, so a little water wont hurt it. and air will still push through. you arent talking about drenching the filter... you would only get a couple drops on it at most.

Shermen

maby that is the reason their hasnt been a ram air hood air box put on the market. we would have to make somthing with a little motor to close the hood scope in the rain. with one of those little rain cencors that some cars have for there wipers.

Many people have mentioned the ram air hood as a "power adder"
front facing scoops only work in terms of cold air until you hit about 200mph
then they "ram air" on a n/a - sc I'm not sure
it's the "cool factor" 'cause I got a scoop so look out - that drives purchases

as mentioned in an earlier post - "cowl induction" style will yield better gains
high pressure on windshield
low pressure at scoop entrance
reversion
the "big boys" use them at the drags for a reason

I was thinkin bout the same thing...if i bought the SS Hood, somehow make it functional like the LS1 Camaro or the basically like the Trans Am Ram Air, but it would have to be somewhat like a newer mach 1 mustang.....

redlineblueline

i dont see the ram opening as letting water in and being a problem look at the evos that have the opening on the hood with only mesh over it

1gmfanatik

As far as the SS/SC goes, getting something like the Extractor Hoods would be best to help cool the motor/supercharger. For the rest of the models, it would all depend on your specific preference on appearance. You could have one that re-routes the intake, or you could have the opening over the factory location.

As far as water goes, I don't see you haveing too much of a problem unless it's the kind of hood that has openings directly on top and has no way to re-direct the water coming in. Even then, it shouldn't be too much of a problem unless you completely submerge the air-intake under water.

SSdan

I want an evo type hood. Cut out almost directly behind the Supercharger basically where the Fuel Rail cover is. Then my S/C would be loud as f!

articzap

ROFL! The cowl hood is used alot for its cooling purposes because it allows cool air to flow from and straight out the back.

SS/SCking

You can get "ram-air" on a SS/SC if you have a cai by taking the drivers side fog light out......

celicacobalt

the rk sport hood is ram air if you have a 2.2 or 2.4 with a short ram intake.

lol ive always thought about doing that on a car with factory fog light holes
