Air inlet ideas

[ClowesClause]

1.5" diameter is really too small to get any significant amount of flow, especially with all those bends.
2.5" / 3" would be a better option and use flexi hose rather than PVC with sharp bends.

i wana have like a descrete kinda inlet....like its not gonna go around the filter, just kinda a direct flow to the filter...or would flex hose still work better???

Flex hose will work better.
If you want it discreet, paint it black.

i shall try that soon, thanks

i run a 2.5 inch cold air feed pipe under the air filter and direct it passed the indicator, passed the horn, and out in the front grill as above. horn bracket needs to be moved/bent slightly for the pipe not to be bent.

it is very effective, if you blow in it or stick a hair dryer at the front it comes out with force the other end. The rain cant travel upwards, so safe there, but i did put 2 screwdriver holes at the bottom area to let it drain if i hit a puddle or something.

That is pretty much exactly what i want to do....could u post up some more pics or DIY cuz i would really like to see what u did

Ugh... not this again. There's another thread going about this topic right now, and everyone is fighting me on it... "lots of people do it, so it must be good!"

Before you modify your car, do this. Have a friend drive a car while you're in the passenger seat. Have him go about 90kph. When it is safe to do so, put your head out the window. Keep your mouth closed, and breathe.
It will be difficult.
Why? Because the air is rushing around your face, essentially creating a vacuum around your nostrils. Rather than ramming air into the holes in your face, you are fighting the rushing air to suck it in, changing its path. You are working HARDER to breathe in that rushing air.

Now, when you put a cleverly disguised hole in the front of your car, this same thing happens. The front end of your car is meant to be aerodynamic. It is meant to cut through the air. A hole in the front of your aerodynamic front end is going to be like your nostrils.The air is going to rush around this hole, making your engine work harder to suck it in. There's a reason why intakes are placed in areas where they can breathe ambient air.

The only way to ensure such a "ram air" effect is to modify your front end so the air doesn't rush around. Technically, that "interfooler" joke of an intake filter is a better idea!

did this about 100mph. you can't breath at all.

you are right that its hard to breathe at high speed, however if you have an end piece that is correctly tapered then the air that rushes in is directed up the pipe, even if 90% hits the front of the car and goes else where, some air has gone up the pipe and will be cooler also.

i totally agree and well its already done so we can stop bickering about and i still stand by my statement of if F1 teams spend BILLIONS of dollars of R&D on there cars id rather trust them....deev, the way u explain it there radiators wouldn't work....and ultimatley isnt it my decision on what i want to do.....if ppl always say that vented hoods dont do anything the y do they make them

An F1 car and an almost 20 year old Honda Accord are very different things.

deev, the way u explain it there radiators wouldn't work....

That makes no sense at all, lol.

[ClowesClause]

That makes no sense at all, lol.

well if the car is designed to flow through the air then the air inlets have a "bubble" if u will and no air will go inside which im saying is not true....air like all things in thing in this world want to take the path of least resistance ie: not moving around too much. therefore air will want to travel in a relative strait line and if this line happens to go into a hole (my inlet), it will flow into it

No one is saying no air will flow in, just less than if you were sucking in ambient air.

Unfortunately it doesn't happen to go into your inlet =/

Edit: Oh and I believe a radiator functions the way it does because it has a large amount of surface area, silly.

Lol. I suppose I'll add my piece in here. There is a lot of misconceptions about how ramair actually works. People will say things like stock cars have it and f1 blahblah.

I'd like to point out that on EVERY stock ram air set up the inlet is on the TOP of the hood, where aerodynamics direct the airflow into the inlet. If you have ever seen a windtunnel and how air flows you would understand why. To fully understand what deev is trying to say might be difficult, but air in the front of the car will be very low pressure due to the basics of aerodynamics. It will be pulled upwards towards the hood then back as the high pressure air from there pulls the air in front towards it in sort of a vacuum. A vacuum AWAY from your inlet.

That said, if you know these basics you can use them to your advantage successfully. I don't think there is anything wrong with your basic concept and desire, just certain physical laws are against it.

Hell, fabricating a front valance to direct high pressure air to an inlet would not be a bad idea.

:edit:
Also, the path of least resistance in this case would be up, away from your inlet, and over the hood. Going straight would be too turbulent.

[SOHC-FTW]

Like that?
Or do you mean ducting from below the indicator to the airfilter?

Where do i locate one of these bad boys?Like the idea very much and the look aswell.Ive had all kinds of intakes and the one i liked the most was the AEM V2 but id like to try one of these.

[Ander]

eBay, lol.
Although I can't help but advise you to spend your money on something else.
