pods on civics,

[dsp26]

pro's:
will help your car breathe better..
more performance..

con's:
oil type filters are illegal in most if not all states.. due to risk of engine fire from heat or backfire up the intake valves and back to the plenum

have a read of the many threads on SRI (Short Ram Intake) and CAI's (Cold Air Intake) and decide what you wanna get..

SRI/WAI -
pro's - faster throttle response
con's - heatsoak, sucks up heat from engine bay <-- Not when combined with a CAI tube feeding it. It doesn't take long for it to cool down.

CAI -
pro's - cooler air i.e. more performance
con's - filter gets dirtier due to being close to the ground, possible hydrolock if you drive into a "large puddle"
is also the least responsive due to the longer path and more bends

^^^ disregard that test was conducted on SR20. same physics apply to every car.



A TRUE INTAKE SYSTEM CONSISTS OF:
- Tuned length straight pipe (AFM/MAF in optimum position)
- Thermo Spacers
- Heat wrap around the pipe
- Bypass valve
- Decent POD

A DECENT BUDGET SYSTEM CONSISTS OF:
- retaining stock box
- replacement high flow panel filter
- widening of feed hole on box and replacing with a 3 inch pipe aimed at say a spare/empty air dam if you have a bodykit.

i recommend a reaplacement filter for your stock box man ala hi flow K&N

but most pod filter elements offer less restriction to airflow, which means less vacum, which means more air into the engine, and also more throttle responce

another advantige is the circular shape helps direct air better into the circular intake tube, and can offer larger area of filter cloth,paper in a smaller houing
but if u dont box it up and only let it breath cold air it may offer less power once the engine is warmed up

Given atmospheric pressure, just how the hell does a Pod allow more air into the engine.

We are talking NA vehicles here. If you have:

a) more aggressive cams
b) beter exhaust system/headers (aka fully tuned)

you can allow the car to breath better, along with a pod.

A Pod by itself does absolutely nothing - put a stock car on a dyno yourself if you don't believe me.

A pod does NOT force more air into an engine through swirl characteristics or anything else as the butterfly valve in the throttle negates any value whatsoever. It's like saying the Hiclone increases power

The ONLY way to increse the volume/density of air swept into a cylinder is FORCED INDUCTION aka Turbo/Supercharger as it beats atmospheric pressure.

Simple Physics.

so dose it or dose it not give you more km's per tank???

that the only reason i was concidering getting one, who eva answers this please take into account i drive like a pussy,(not really a speader) LOL

it does if you can control your right foot ... it should run the car a bit leaner due to the flow. An AFM/ECU cant compensate as well as you guys think.. though i have a high CR SR20, my A/F went from ~13.7:1 peak to 14.3:1 just by replacing the ribbed factory rubber intake with a smooth alloy one.

well you try sucking through an unlit filtered cigarette then suck through a straw and tell me which one was more restrictive?!?!

remember that NA's create a venturi effect.. same as bunsen burners. the 4 strokes happening in the combustion chamber SUCK oxygen hence why a good intake system really matters in response.

also keep in mind that filters dont matter the same way on a turbo as exhaust flow is what dictates response on a snail

Let's use your analogy (which are slippery at the best of times).

Let's say you suck air through a cigarette at a constant rate to fill your mouth and lungs.

You then use a straw.

All being equal, a straw does NOT increase the capacity of your mouth and lungs.

It may increase the speed that the air gets to your lungs. But a panal filter is not a cigarette and a pod filter is definitely not a straw.

Now f*ck the stupid analogy off. Without other mods:

a) your exhaust cycle is not scavaging residual fumes any better than it did before (OP has not mentioned other mods). Volume has not improved. When it's full it's full and none of your dreams will change the laws of physics.

b) if a panal filter flows to max performance of your motor as does your pod, how has it improved the airflow?

Reality

I extensively tested a CAI, pod and panal setup on my SiR with zero other mods.

Panel 1: Custom made and bench flowed: 1KW @ FW improvement over stock.

Panel 2: K&N .5 KW @ FW

AEM CAI modified for a SiR engine bay: .5 KW @ FW Throttle response wasn't as sharp.

SRI K&N Pod: -3KW @ FW.

All tested with the engine bay closed and a fan at the front of the car.

20 years of building performance cars, from straight 6s, turbo and NA 4s and the odd V8 and I have never seen the improvements claimed by pod manufacturers for a simple bolt-on "modification".

Real workshops consider it a wank factop unless you go all out and make it part of a package. Of course, ricers claim otherwise.

Well if it doesnt do anything then why does the exhaust note get deeper?

OMG... hahahaha.... quoted so you can't ever delete that post

[egSi]

im with setanta.

*looks at my oem setup*

get a K&N panel man

[simbadda54]

lol this has been covered like 50 times

[crx_boy7]

yea just get a k&n pannel if ur a lazy person, it provides good power benifits
and is legal!!

OMFG do i have to explane everything in perfect details?!?!?!?!??!!?!?FAAAAA

ok look the way the engine breaths in is by the piston moving down, this creates vacum which sucks air into the cylinder, the air has a certain amount of time to get in before the valve blocks it off.obviously the more air that the engine can suck in the more power it will deliver.
the air has restictions like the size of the valves and all the other crap in the engine and then u have ur TB. and ur filter

ur engine has a certail demand for air per second which in Wide Open Throttle mode causes a vacume to be created between the filter and the valves, so obviously the lower this vacum is the more air can be sucked in by the piston, AND SOOO...
if ur filter is less restrictive ther will be less vacum in ur manifold and more air will get into the engine
GOT IT????

the reason for the SRI type making low power is that its sucking in warm air(low density air), with a low conentration of oxigen which is required for the fire to ignite and so less air means less feul for the same air/feul ratio, and generally has the same effect as a loose throttle cable or about 80% throttle

u should be ashamed of yourself for causing me to waist my time typeing up something so simple

No, i mean really, you claim it doesnt do a thing over a stock filter or a good panel filter? May sound noobish but if it doesnt make any difference at all then why does the note get deeper when you swap from a stock filter to a good panel/pod?
