Whats the speed/Force against the car to create 1PSI?

[DatSRBoi]

I was sorta sealing up any air gaps in my fender today afterinstalling the cold air extension to advoid water from rain when it rain.. I notice that after removing for fog/driving light on the bottom I get allot of air coming into the small area where the cone filter now sit. I also notice that I somehow sealed up that whole compartment so no air can escape once in enters there.

There is like only one way in and one way out of that compartment.. Way in is through the fog light hole and the only way out is through the intake sucking air into the engine..

So heres my weird question haha since I got nothing better to do... Since theres probably going to be allot of air buildup in there at high speed and only way out is up into the intake... How fast does your car have to be running to create 1PSI of pressure? I dont know if its true or anything just curious since turbo and supercharger compress air and here my car is ramming air into a hole that has no way out other then the intake at WOT..... So can my car create at least 1PSi of pressure and if so at what speed?

Im just throwing out thoughts and weird ideas off my brain.. Gotta learn somehow you know so Im posting it up and asking..

Also is it better not to seal it up and let air flow freely through it? I sorta covered all the gaps and holes around there so no air can flow through areas where it use to.. Sorta like a box with two holes... one to enter and the other is through the intake out..

Well do you want the pressure???
Maybe at 60mph?????
Not sure.
I'm guessin'

how did u seal the gaps?

how did u seal the gaps?

Long story made short.. I created a box from hard plactic big enough to fit that compartment area with two opening.. One for the air to come in the foglight.. and one for the intake pipe to fit into...

when I took out the foglight it seemed to run weird like it was getting too much air and not adding the fuel correctly.

strange question

it depends on what RPM your motor is running at, because that determines how much air the motor needs to pull in.

maybe maybe maybe you could build up 1 PSI by about 100 mph cruising in 5th gear, but as soon as you drop down the gear to a higher RPM and hit the gas, the intake will build a vacuum and your 1 PSI is gone.

get a boost gauge and you tell us

Probably never... If you think about it physically the air would just go around it.

I think it's kinda like taking a plastic grocery bag and runing with it or holding it out a window, air just comes in til it has nowhere else to go, and then it just goes around it, granted there's greater air pressure in there, but only as much as is allowed and ther ehas rto be some serious work to make anymore.

My theory is this aribox thing you have made won't effect performance either way as the intake is probably... or has to be sticking through it, and will just be getting air bouncing around in there that would have previously spread through the engine bay. So keep in mind because not so much air can fit in there due to this box, a lot just goes around it, it doens't just continue building up in box, otherwise you'd theoretically get enough pressure to explod ethe thing.

I don't know if any of what I'm saying makes any sense, but I believethat somehoe, with this setup... just maybe at around 120 mph you could get about half a PSI of pressure, but I really don't think it's going to happen.

I could be entirely wrong, and have no background in this stuff, it's just a logical guess.

your talking about the ram air effect, which isnt really going to work in your case. To get this idea to work you would need a straight pipe running from your throttle body pointing straight out, then take the hood off (or cut a hole in it so the pipe sticks out) and drive about 100mph before there would be a difference.

In your case it is easier for the air to go back out the front of the box instead of through the filter, around a couple of corners, and into the throttle body

[DatSRBoi]

Hmm Good point.. Yeah I took the Box thingie out... Guess it didnt work haha.

There is no real way to judge exactly what speed you'd have to attain. The TB size will control how much air you're able to pull in as well as the piping, the bend of the pipes, the filter used, etc. It all changes everything. I'd say that if you're looking to make more power, the intake isn't your best option, it's just a good option for some basics. It's time to get into engine work for you my friend .
