Hey everyone,
A subject in Year 12 I need to do is research project. Essentially, I have to pick a topic, research it and come up with an answer. My question is 'Does a POD filter effect the preformance of a vehicle?'
So if you could please leave your opinion below it would be very helpful thanks guy!

Easy way to test other than getting opinions
check using vacuum measurements on the intake side of the filter before the t/b or turbo. If you dont have a vacuum gauge, you can use water in a tube. Youtube it.
Then you need to check IAT's, just need a sensor, the mapping data for it. Use a multimeter and plot out the averages I guess.
Then do your specific density of the air at temp, so how much it would affect HP. Then do some research on how heat can affect how much timing you can run etc etc
The question should be, does a pod filter increase power from a standard filter?
You could measure it by performance testing such as on the street or a dyno read out. You could also put a temperature gauge in behind the filter and see what effects it's having on temperature.
Essentially it's going to affect power in two ways, how much of a restriction it is as opposed to having no restriction and what temperature the air entering the motor is.
Mightycarmods made a youtube video in which they compared a regular panel filter against a pod on the dyno and found that pods were basically useless in most applications. Not to say there aren't plenty of exceptions but that's what they found through their testing. May want to check the video out, could probably be useful for you.
When I brought the Calais turbo, the last bloke had a 3 inch pipe running from the front bumper to the bottom of the air box.(like a ram air setup) I thought it was quite unique. Anyway, I've had many discussions with friends & since I live in Gippsland where all the roads are 100km/hr I thought I'd remove the cold air box setup & place a K&N pod on. Straight away I notice gains in performance & takeoff.
I belive driving around at 100km/hr their is significant amount of cold air running through the engine bay to keep the air intake cold. On the other hand living in the suburbs where the speed limits are restricted a cold air intake(ram air) would be a advantage.

You have asked for subjecting opinions. You need measurable outcomes to come up with an answer.
before & afters of:
- Emission measurements
- Power measurements
- Torque measurements
I doubt you would be willing to pay for this but you can always ask a performance shop if they have any data.

And all this is all over the net. Have a search. Theirs literally hundreds of topics/threads.
The flaw in the tests that were conducted by mightycarmods is they replaced the stock airbox with a pod filter, stuck the car on the dyno and checked to see difference in power. The tune was not altered on the car, intake temps or air fuel ratios weren't monitored.
It's like putting a tank of e85 in a car that isn't tuned for it and saying the car ran terrible and had decreased performance ect.
No I dont need to preform any tests because it would be a bit difficult to do that but, opinions from mechanics, fourms and general people
Thanks for everyones input btw its really helpful! (:
If your task is to research whether a pod filter effects the performance of a vehicle but you're only going on opinion then how do you know who's opinions are correct? Would be much more convincing if you had proof to back up your points.
I remember a High Octane DVD where they used a Honda CRX. They tested the pod filter myth to see if there was any difference & apparently there was a noticeable increase of power(rwkw).

Exactly,
If you don't require evidence or even have to conduct any tests why not just make it all up? What difference will the teachers know?
Eg: my studies show that after asking 100 car enthusiasts from a range of different taste in cars and mechanical minds. 88% said that they think a pod filters is useless, 13% stood by their power pods and the rest didn't know what I was talking about.
A+
