Have you really looked in to the costs of having a custom hood made, or is this something you are going to undertake on your own?
That said, ever thought about buying something else? (being pratical is such a pain)
(I wonder if I could start more paragraphs with “That said” if I tried)
By indentation, you mean where the filter sits, correct?
This is kind of what I was thinking, sorry for the quality.
That’s the hard part…
When driving, water can enter an opening in the front and sides.
When stopping, like you said, any water will run forwards, so an openings in the back will also be useless.
So far, the only thing I’ve thought of, would be similar to this:
opening restrictors filter
(front) ] < < …
There would be a small opening on the left side of each “<” But even doing this, some water could possibly get in.
If I had to design it for a car sitting still, it’d be easy.
The hardest part is keeping water out with the car in motion and stopping.
I plan on doing it myself, having it done custom, I’m sure would cost much more then the $300-$500 price tag on prefab fiberglass and CF hoods now.
Practical is great for a lot of things… but for car stuff, I try to learn as much as I can, and do as much as I can myself.
I feel that it’s much more rewarding when I complete something that works out.
And if/when it doesn’t work, I learn from it, and either alter the design, or go back to the drawing board/ask for help on why it didn’t work.
Damn, much better than I could ever do.
This is exactly what I have in mind:
And yes, I know I suck at drawing.
My goal is to cool the engine bay/header using the heat extractor/WRX scoop. I also considered a plain flat vent on the rear of the hood as well.
The goal of the filter setup is to introduce the coolest air possible, using the shortest length of tubing possible, and at higher speeds (when I reach them) to act almost like a ram air setup.

Well I honestly haven’t seen or heard of anything like this being used on a sport compact. I’ve known domestics to use an open hood/open element for years.
I wanted to try something different. And I’m sure it won’t produce insane amounts of power, I’m not expecting that at all.
I do expect a small gain, and weight reduction at the same time though.
And if it doesn’t work, we can all learn from it.
Would your ultimate goal be this?

sounds like alot of pointless work for minimal gains…but whatever floats ur boat
Be what? lol
Walter made a valid point.
If it is for the track why run a filter at all?
I’m going to one up him and ask why you are going to run a hood at all? That will give you all the airflow you need to the intake and to cool the exhaust (which you don’t want BTW). You want the exhaust hot. You want the stuff around it cool. This is why you see heat vents on the 03-04 cobras and the evos… and an intake for the IC on the STI/WRXs.
Air flow over the vehicle. :shrug:
If this is a track only thing, and will always be a track only thing, just make a big ol hole with a straight shot to the engine, run a fine mesh/foam over it in order to keep bugs/stones/leafs out while you zoom down the track.
Making an all out track monster never works with a DD, so I wouldn’t try.
airflow over a cavalier? I don’t think that will effect the times so drastically that it is not the best idea in this thread;)
Honestly, none of the ideas in this thread will drastically effect the times of this car, nor will anything that is going to let it stay a reasonable daily driver, hence my point.
If you want track performance, get a bottle. :shrug:
Ram air is really more of a marketing thing. Cylinder vacuum overpowers any ram effect that you can get from a setup like this until high speeds, like around 100-150 mph IIRC.
Having the filter butted up against the hood will be a fitment nightmare (not to mention the surface area will drop dramatically if debris/bugs etc pile onto the exposed element), although there are plenty of cavi’s that you can pull partsyard hoods from and practice on.
Is this more of a road-race/track thing or drag strip thing?
i think that weather factors such as temperature, humidity, barometric pressure, etc. will effect his track times much more than this attempted mod ever would/could. even if he accomplishes his design, he very well could take it to the track and run .1 faster, or .1 slower, and there would be no verifiable way to attribute this increase/decrease in time to the new “mod”.
the only way to effectively do mods that have not been attempted or perfected before is by using an accurate dyno in a before and after setting under similar conditions and comparing the results.
in all honesty, i think that for someone who is trying to learn to work on/mod his car, you should not be trying to pioneer a new path in cavalier modding. there is probably a good reason why people are telling you to spray or put you money elsewhere. it is because what you are trying to do makes no sense because it is backwards. you are putting the cart before the horse so to speak, trying to invent things that will make your car faster, when you dont fully understand how it works in the first place.
this is the same logic that befuddles people when they port out a throttle body themselves, a nice high quality dremmel job, and then they drop 10whp. they say “wait, i thought porting and polishing makes EVERYTHING faster!!!111!!” NEWSFLASH!!! just because you port something doesnt make it flow better, flow more efficiently, or flow with less turbulence.
there is a very specific engineering involved in engines, horsepower, torque, and how to make them run more efficiently and powerfully. while at the macro level the rule of thumb is more air (supported by fuel) = more power, it is not as simple as re-engineering hood designs, homemade port jobs etc.
for all you know, your new hood could create more air turbulence within your intake manifold, and you could lose power.
well put
i have the stock airbox and tubing if you want from a 2.4L engine
i just put a CAI on the alero, and i was def most fine with it. :gotme:
let me know if you want it
so all this bs crap is because you are trying to create a ram air hood instead of just buying one???
so i found out about this bad boy the other day at southgate. i think i was making fun of ram air hoods, which somehow led me to my old standby of making fun of ugly girls… at this point, someone informed me that there was a thread on nyspeed where i could make fun of BOTH!!! Alas, I arrive at the thread and see that it has been pretty well handled by my best friend/arch nemesis sir walter, so i will keep it brief:
The stupidity of this idea is actually so great, that i think i will explode if i even think about it for much longer. I am pretty sure… nay, certain, that if i ever saw an air filter mounted in such a fashion a thick stream of stinky vegan piss would make it’s way past whatever water deflection elements were in place and straight into the heart of your motor. And please, make said deflectors of plexiglass or lexan, that way, i can ensure that every square inch of filter element is thoughroughly doused in caustic urine that, with any luck, will also wash any harmful dyes along with it as it pools in your throttle body.
But please, don’t let ME discourage you, just pray i dont have “the runs” when i happen upon your car, in even the most well lit parking lot.
SAYS THE DUDE WITH BLUE TURNSIGNALS
BTW
what a dumb fucking idead…
Jesus christ how about you skip the fagtastic hood and craptastic filter and maybe instead just throw a 75 shot on
:bloated:
newman=hilarious.
Hey, if you have all of the time in the world then go for it. What I dont understand is if you were originally concerned about filter color to blend in or get the look you want, then why the fuck would you run a primer hood? That wont blend worth a shit and look like ass.
Run no hood, and solve your ram air filter and engine cooling dilemmas or do what you want. But if your gonna spend 50 hours building a custom ram air, then spend a bit more painting the hood to go along with your custom color filter.
