Pod Box....Really..WhY?

[Guest RedLineGTR]

Got a pod recently for my r33 gtst instead of the drop in filters for the sotck air box. Does anyone have a Custom Air box Like on the Unique Auto Sport Site to house the pods in. Does it make to much difference, is it really needed. Can you get them in melbourne anywhere or if anyone is selling one, or make one please contact me either email [email protected] or PM me as soon as you can.

Thanks

yo! , yes you need a box

not only will this seperate the cold air from the hot air which the pod would be sucking if purely exposed under the bonnet, if you get pulled over u will get a canary due to the pod but if its in a box it should be sweet.

there is a template floating around the forums i think INASNTS name comes to mind...do a search on these forums and im sure you will find the template...making it up would be a piece of piss.

He just sent it to me

Ill send it to whoever wants it.

In terms of performance, even an unshielded pod is better than the standard airbox. I drove my car with each, back to back on the same day. Yukk! to the airbox. I do want to shield the pod, but it's not urgent, as I don't even notice significant heatsoak in slow bumper-to-bumper traffic, except on really hot days (then again, you are in Australia....)

The legal thing is a bit of a hassle tho'. I guess there's nothing else for it

[T0nyGTSt]

That is strange as Mines use the standard box and their cars always hammer.

Perhaps it is the relative lack of noise that makes the car seem 'slow'.

Any performance increases from having a pod in the UAS box coz its getting only cold air ? Or is it only a 'healthy' type mod ?

[predator]

i think a well ported box and pod filter are going to give pretty similar results. I think the whole pod thing is a bit overrated just because the standard air box is so screwy.. Make a few mods to the std setup and it will probably be legal and work just the same. Noise is a different thing - guess certain people like the pod noise (i'd have to hear both myself to tell what i'd prefer i think).

[moondog]

I definitely prefer the lack of noise, but I had to put the pod back on because the car was so sluggish with the standard box. Granted that was totally standard, and as you say Predator, modifying the standard box and using a higher-flowing panel filter may work about as well. Easier to just chuck in a pod though I reckon. Pity about the noise - although my wife loves it (hoon-girl )

[2fardown]

Adding a POD gives you 2 tenths of stuff all power increase. Just put an aftermarket panel filter in your stock airbox. They draw in cold air from under the bonnet as well as filter A LOT better then some POD's I have seen.

[akeenan]

2fardown is correct! the only real benefit if you like it is the induction noise!

EnricoPalazzo i would really like to get hold of that template if you dont mind my email address is

Thanks

I agree to some extent that it is induction noise that makes it go faster i mean which one of us DOESNT love to hear the sound of our respective turbo spooling up as you chop some looser in daddy's Gen3 V8 commodore??

But, at the same time there are advantages above the standard air box when using a pod filter if done properly.

1) Mount the pod filter to the air box (duh).

2) Build a partition around the pod filter (which i am hoping EnricoPalazzo will send me a template for)

3) Providing you have an aftermarket front mount intercooler then you should have one of the holes (where the original little intercooler was) free. Stick a piece of bell mouthed PVC pipe (both ends) into that hole.

The advantage of doing this is that you now have a large hole drawing air into a pod filter instead of that small spatula sized snorkel which actually runs over the radiator (good for extra hot air).

Another thing is that the ribbed pipe between the air flow meter and the turbo is no longer experiencing too much suction which can close it of. Yeah pretty dodgey i know but i have heard of that pipe closing up when the pipe is sufficiently hot and it has to work hard to suck the air in.

For the non believers get hold of a manometer (piece of pipe with water in it). Use it to measure the pressure drop before and after you use a pod filter (between turbo and airflow meter). That would settle all this arguing

A dyno before and after pod filter will do me fine.

R33NT is spot on. Only use a pod when you have a fmic. Then seal the pod in a custom box and with the remaining ic hole resize it to fit a 4-5 inch drain pipe, scooping air from the far right hand hole (passenger side) in the front bar (standard front bar).

One more time for the record...

Mine's use the factory air box on their 600+HP GTR's.

For 'alternative sounds' turn to the pod.

Power gains? Well over a stock paper element airbox a couple of horsepower (maybe 4 or 5) are to be had using either a K&N style replacement panel OR a pod with a cold air box. The standard panel will flow 900odd CFM, more than enough I'd say.

The air feed to the factory air box can be improved but, it is actually taken from the very best spot for air pressure (under the lip of the bonnet). Under dyno testing this is something that you won't pick up (the air movement is nothing like actually moving the car) but, the results under speed are worth the trouble.

Finally,

the sprung rubber intake pipe from airflow meter to turbo is quite restrictive indeed, more gains here (about double) than from messing around with the airfilter. Cheeper as well.

Enrico, please send it to me too [email protected] [i am hoping it will be suitable for the 34gtt].

Thanks

how bout de-meshing the AFM's does that really work? i have had ppl who swear by it..but fark that im not going to do it

[R33NT]

I already discussed this in another thread. I have read in one of the performance mags that removing the mesh from the AFM gives a gain (they did a before and after dyno run showing this).

One person in that thread complained about a bit of backfiring and as i stated the freeing up of the air flow may have some effect on the way the AFM measures. I think this is the case because in my apexi powerFC you actually need to tell it in one of the menus that it you have switched from a standard air box to a pod / low restriction device and i doubt that is just so that the user feels special.

As for the Mines GTR i dont really care that they use an air box because i can see that the size of the orifice that the air box is drawing air through gets very small at one point (as it passes over the radiator) and i will have to check but i really dont think it is any where near the diameter of the pipe the AFM is at that point.

Hmmmm Al it looks like you have been reading the mods section of skylinesdownunder.com aswell

[inark]

i thougt mines INCREASED the size of the pipe not decreased it.

thats what they said in that R34 vid if i remember rightly (having a really bad memory one would probably say i havent remembered rightly lol)

[rev210]

R33NT,

Don't go 'turfing' that air feed mate for all it's little bumps it isn't going to restrict a 300HP@motor (if your lucky) GTST.If it concerns just add an additional pipe feed or re manufature it without bumps. The pipe from airflow meter to the turbo is however very restrictive and can be worth maybe 6+ HP , double the airfilter mod.

[NismoR34]

rev210 you seem to be fairly against POD's being a worthwhile mod - in terms of actually increasing power.

Have you read this article: http://www.mkiv.com/techarticles/filters_t...st/2/index.html

???

Everytime i read about pod's there seems to be conflicting opinions...:confused:

Does anyone know where I could get a replacement pipe *off the shelf* to replace the factory ribbed pipe from the AFM>Turbo? Or is this a *custom* job? if so who has done this and where did you get it made up? Prices?

I am not so much worried about it being restrictive as i am about it collapsing!

Please help!!!
