What are your thoughts on Ram air systems and how they work?
1. They suck
2.same as stock system
3. thanks, I am an expert.
:clap: :clap: :clap: A clap for the idiot.
A Ram air system is a form of induction commonly found in alot of domestic
performance catalouges. This is a form of intake placement that introduces
the intake cone or filter into directly oncoming air. Sure it all looks
good on paper, the only problem is that for the RamAir to have a noticable
forced induction effect on the intake of the car you would have to be
traveling in excess speeds of Mach2.
If you've ever seen NASA(I think NASA?) they created an engine with no moving parts. They simply fly the engine behind a jet and once it reaches high enough mach speeds the air is moving fast enough to be compressed and fuel is added and ignited and the engine works.
RamAir hoods look cool and they might actually cool your engine off. As far as being a superior form of intake setup, I'm going to have to give it a shifty nodd. Oncoming air may be colder and more dense, but I doubt it would be any more effective than having a cold air box or simply a cold air intake.
We talking about the scramjet? Hmm that sounds familiar. Must be some
really clever people out there to get it of the launch pad wouldn't you
So are you articulating thoughts on the ram air or do you have some supporting reason why it doesn't work as advertised?
Not to sound like a post whore, but CarExpert you are a idiot. He asks you
a question and asks you for advice, and you a self proclaimed sarcastic and
not to mention idiotic sorry excuse for a "CarExpert" gives him a sorry
excuse for a reply much less an insult.
Well, my take on RAM cold air intakes are that they pretty much have no effect on the performance of the engine. Even in CarExpert's sarcastic and insulting words, there is truth, not much of a difference then your stock air box.
you need mach 6+ for scramjet
nah, he's still googling the info
I've allready given a supporting reason as to why it does'nt work as
advertised. I think you must have missed the part where I said.
As you should know, cars don't travel at mach speeds. Therfore the system would'nt be as effective as it is said to be.
Actually I was being benevolent on this occassion, because one can only
take so much of a hiding.
The truth, as CarExpert will concur, is that it does not "look good on paper".
I will let you investigate "stagnation pressure". If you have trouble ask and one or two other members or myself will help you...yes believe it or not thats what some of us do, just as we appreciate it when we get help without abuse.
Investigate what? I've dealt with enough RamAir applications to simply tell
you they don't work as well as somone would have you beleive. Although I
have no idea what stagnation pressure(or the sum of the static and dynamic
pressures of a fluid) could have anything to do with air induction.
But, whatever you'd like to beleive is what you'd like to beleive.
Well you can't say that I didn't try :mrgreen:
BTW just what is it you do in the auto industry that makes you such an angry ant and gives such a skewed viewpoint on the basics?
The point of a question is to obtain information that matters to us and
only us. That is a combination of your own interpretations of who I am
complied to project a statement that you think deserves a response. What I
do and who I am is not the topic at hand nor does it serve any purpose to
More simply put, stemming back to our original topic, you can choose to believe what you want about ram air intakes and "stagnanation pressure". I've seen what the dyno numbers and test prove. If it is so that you'd like to beleive what it is that you say you believe, continue to do so....
So unless you have anything else to add relating to the topic at hand I'd say this discussion is over.
Well you did come uninvited afterall. I was asking CarExpert for his opinion not yours. I open the door to you and you slam it in my face, how rude is that. :laughing:
I have no idea of the merits of a ram air intake performance wise, but the bling factor on a chromed version sitting on a big V8 is pretty high. :hi:
This is a forum, everything you post is open to the public. If you wanted
CarExperts opinion then you could have simply sent him a private message.
(Just letting you know for future referece. Just in case you have an problems later on about the publicity of your actions and words. :thumbs: )
DSMer, I read the thread "everything you need to know about intakes" but
when your saying ram intake uses the oncoming air, then is the filter in
the engine bay or out? I thought that a ram intake was just like a regular
intake in the engine bay and is short and uses the hot air in the engine.
In catalogs I see there are short ram intakes too. Are they the same thing but just shorter?
First off, DSMer you're dead wrong, you don't have to be going even close
to mach speeds, why do you think higher speed drag cars have them? Such as
funny cars. You think they're going to lower their aerodynamics that much
for no reason? I think not.
Ram air doesn't do anything until you hit 120mph. Even then the difference is so unoticeable, and it can hurt the car more than it can help it due to the lowered aerodynamics. In otherwords, on street cars, it's just for people who think they're cool.
CarExpert, ram air intakes the also called hood scoops by less proffessional people. Because it's forcing more air into the engine bay, and once you hit a high enough speed, the engine needs more air than what's in there, then that's where the ram air comes into play, it gets more air circulating in the compartement.
First your openly admitting that RamAir even at 120MPH does nothing. My
statement was for "RamAir to have a noticable forced induction effect on
the intake of the car you would have to be traveling in excess speeds of
Mach2." Maybe Mach2 is a wild exageration, but I know the numbers in speed
are really up there for noticable gains of power.
Maybe you should read my words more correctly before you make such vivid assumptions as to my being "dead wrong".
I have'nt seen to many cars where the intake element is outside of the car unless they were running blowers on top of a big block V8. No the filter is within the car and is placed behind and opening anywhere in the direct flow of ambient air. The opening or funnel could be in the bumper, under it, on the hood, in the side panels, just about anywhere you're going to get airflow at moving speeds.
ShortRam(as I explained in the article also*yeah budy sure you read*) is simply a very short intake that is usually contained within the general engine area
You still don't need to be going in excess of any mach speed. It's useless on a street car I said, hurts in more than does any good. In the faster drag cars it does give a very noticeable gain. When you're going 300mph at 10 grand your motor needs every bit of air it can get.
in a ram air u ket like 5 horses more at the crank which is like .5 to the tires buy a CAI instead
When a engine is at high speeds (rpms) it creates a vacuum because air canot be puched in fast enough so it must be pulled. With a restrictive airbox like on the lt1 the vacuum becomes bigger than the airbox and air hasd to be sucked through cracks in the airbox very much hindering performance and breathing capability of the enigine. With ram air there is no worry of the vacuum becoming to big for the airbox because the air is sucked straight out of the sky or whatever. So ram air is better than a restrictive air box but the only thing i canthink of that would make it better than a cold air intake is that the air coming in the scoop may be a little colder because its farther away from the engine. i read in a magazine a while back that the ram air system on a 04 mustang mach 1 really only had a "air ramming" effect above 80 mph.
i just revived a thread im sorry
Thats alright, atleast it wasnt a "What car should i buy, car A or car B?" thread.
I don't like the ram air intakes, its been proven that cold air intakes
gain you more horsepower(I think its because it has a longer tube which
means the air has a longer time to get cooled off and the entry
point(filter)is located outside of the engine bay for cooler temps, right
above the wheel well on my car) Sombody correct me on this if I'm wrong.
BTW, I don't even understand why companies still sell ram air, is it just
because it was developed first and they need to get rid of them?
EDIT: AEM V2 is even better so it seems.
And just exactly where was this proovin and who prooved it? HUH? A longer tube would give the air more time to get hot because its closer to the engine longer. Now think about it. On your car you said the cai is located right above the wheelwell. so its probably what a foot and a half away from the engine? but still in the engine bay. Now think of all the heat your engines giving off. Its all being trapped in the engine bay because heat rises and the only place to get it out easily is out from under the car but it wouldn't go there because once again heat rises. So that means your cai is sucking up all that hot air. Now ram air sucks it right up out of the atmosphere. Now which one makes sense hot air from a heat soaked engine bay or cool air that comes from far away from your engine.
wow, actually kinda glad this thread was revived. just fyi, nasa didn't
develop the scramjet on their own. a lot of the development was done down
here in sunny queensland, in our mech eng department at the uni where i
studied.... *basks in own glow*
it mentions it here.
the cai entry point goes down through a hole and is outside of the engine bay so it is closer to the ground, hot air rises so it is getting colder air. Thats how it is on my car at least, besides i said correct me if i'm wrong so don't get mad at me.
sorry when I talked about ram air I was thinking about short ram. Re-read this quoted post and substitute "short ram" wherever it says "ram air." Again, sorry about the mistake.
Dont worry about it.
you fools dont know sh**. . .a ram air has to doo also with the type of hood. . it has scoops in the hood that way when you are drivin the scoops work with your intake and help suck in air quicker and more efficient. . . (spellin sucks ass). . . just think of it almost like a turbo. but not quite. . .when you press on the gas you go faster, the scoops help by directing the air flow straigh to where it needs to go. . cuz if you look at regular intakes . .. .where does the air come from. . mostly the bottom of the car. . .ram air solves this problem by letting air come in through the hood. . :screwy:
Thank you for repeating almost my exact words. I care not to hear from you when your going to tell me i dont know "sh**" when you just said almost exaclty what i said. :fu: :clap: :fu:
its funny cuz i was still on the first page... .but its even funnier. .you talk about askin for help when you think you know what it is. . :screwy:
How do you account for hood intakes that face the driver?
There are two types of scoops (that i can think of) that face the driver. Cowl induction and heat extractors. When a car is in motion air is built up at the windshield. The air trys to go up or down it can go down because theres a hood so it goes up and over the car. put a "scoop" or a cowl induction entry point right there and the air can be forced downward into the intake. On heat extractors it just gives the hot air a place to escape (since heat rises) and it helps the engine bay stay cooler. :2cents: :2cents
And Ram Air doesnt always have to do with the hood. What about to old 4-4-2s they had ram air down on the front end
its still basicly the same shit cuz its helpin push air where it needs to go. . .as for the two different types of hoods. . read above. . nailed it on the head. .
Almost a year after the fact and I still don't know if there has ever been a thread on this forum with more misinformation. :banghead:
Well, that'd be a good thing.
Misinformation? I didn't think there was any information. :mrgreen:
Just think, you could have accomplished the same thing by taking no action at all. Leave it to an engineer to find the hardest way possible to do something.
yeah, but the coolest.... remember, we don't care about servicing :wink2:
