more HP?

To add... I saw Clifford's setup a couple weekends ago, it is a very nice setup, that alpine unit is VERY nice I was very impressed.

Yes, I am aware of that. I was hoping that it was a TV screen only and a machine that acts like a deck which holds the TV (no stereo involved)

in my old mercedes, i ALWAYS wanted to have a tv in the car- however the screen would have been right in front of the ac controls and the shifter would have got in the way.

HOWEVER.

i DID think of a way to put a small screen IN THE GLOVE BOX!

perhaps that might be an option for you???

install it in the glove box- modify your door so that the door can close with a small cut out area for the metal arm/brace that extends to hold up the screen- when not in use- open glove box and fold the screen down into the glove box?

the good points of this idea are that it is:

LOCKABLE

NOT NOTICEABLE FROM THE OUTSIDE (unless u leave your playstation controls on the dash)

keeps everything looking stock and kinda brings a james bondish type of deal to your car.

hehe- james had the coolest rides.

Justin!

it gets better- i got bored so i threw my home dvd player in the backseat and i've been driving around watching RONIN!

bwaaaaaahahhahahahahaaaaa

(note to self: look up at the road every now and then)

ok- whew!~

hmm interesting...this post got sidetracked by stereo/TV stuff....HP to Stereos....

So i put my dyno run on a dvd, to watch in my car, to show people how much hp my car makes, and how i tested that... and how my CAI helps with that... speaking of CAI's....

[ty423]

Just show them by punching the car with your guest in your car and let them feel for themselves how fast it is and how well it handles...hehe

[JustinP10]

Well, yeah, that would be much easier, but i just figured i'd try and take the topic from stereo/video stuff back to CAI's, like the way the thread started

[cliffud]

can someone explain why the CAI increases HP through resonance and how it has to do with the length of the pipe and such?

does the length of the pipe matter?

would a small spiral etched along the interior help smooth out wind flow? (same principal with a bullet coming out of the rifle... the barrel is just a tiny bit bigger than the bullet and as the bullet goes down the chamber, it rotates along the interior kinda like the men in black car going through the tunnel in the movie -if you haven't seen the movie, don't worry about it- it rotates to keep itself centered along the proper line)

does this make sense?

would it work?

yes? no?

DON'T ROLL YOUR EYES AT ME!

ahhhhhhhhhh!!!!!!

Rifling does put a spin on a bullet but not to "keep it on the right path". It provides a gyroscopic effect, keeping it from tumbling. This will help prevent the projectile from being acted upon by outside forces and deviating from a straight line.

The two situations are apples and oranges ... far too different to make an assumption like that. First, the path in an air intake is not a straight line. More importantly, what's moving through it is a fluid, not a solid.

Good air intake design is probably quite complex. You could possibly improve the flow rate through the intake with a very smooth passage, or with microgrooves which follow the path (as opposed to spiral) to improve the laminar flow at the boundary layer. However, this might not be ideal for fuel atomization/distribution ... induced turbulence/swirl might offer better performance.

Not trying to pass myself off as an expert. Only volunteering that the subject is probably a complex one.

Sorry, that's all I remember from my engineering fluid dynamics. Any intake guys around that can give some detailed insight?

[cliffud]

just diverting the attention back onto the subject

Wouldnt it be a gas flowing through the air intake path? not a liquid

Nobody said anything about a liquid. Both gases and liquids are fluids.

Therefore air is a fluid.

in physics i think they consider a gas as a liquid because it doesn't hold it's shape.

however- with the air flowing through the intake under a CONTROLLED turbulence might be directed into the throttle body with more pressure than air flowing under random swirling of the air.

my thinking is that when the air is flowing through the pipe- the swirling effect will smooth out the flow of the air and if the flow is smooth- then it will be faster and hopefully more effective.

sounds like it makes sense?

ok thanks, I understand now

Size matters. :right:

As air flows through a pipe a reflection is set up at either end whether there is an opening or a sealed end. The resonance tuning occurs when the reflection wave is in phase with the incoming wave. This makes it easier for the incoming wave to move through the pipe and thus more air will flow. Think of the incoming wave of air as "drafting" the reflected wave. It's easier for it to flow so it flows faster and more air moves through the pipe.

Now for the advanced course.

It's not just an end of a pipe that sets up a reflection. If there is a stepped change in pipe diameter, a reflection occurs as well.

I'm not an engineer and it's been, oh, 24 years since my college physics class, so I might not have all the details 100% correct, but the gist is correct.
