Pod Filter Or Panel Filter?

[NVE57]

im sorry if this has been brought up in the past but it seems everyone only has opinions on it. what would be best (power wise, i know there probably isnt much difference) between a pod filter and a panel filter in the orogonal airbox? put aside legal reasons etc.

lets just use a RB25DET for example.

has anyone actually proven which is better? like a dyno run etc.

I think pod's are dyno proven to be a little better. I have an rb25 with HKS pod and it runs well.

Stock panel filter is good too, and the air being sucked in is cooler (a pod should be enclosed too for best results) but i'd say get a K&N panel filter for better flow.

An aftermarket panel filter VS enclosed pod i'd say very little difference on average street cars. Pods are slightly better i reckon.

I believe the panel filters inside the stock airbox is more effective than a pod filter if ur not going to heatshield around it. As ive replaced the stock filter with K&N pod without heatshield and dynoed before and after it made no difference from would ive seen.

Panel with airbox - winner always when driving around the city etc.

Simply gets too hot under the bonnet with a pod/hot air, not that great.

Pod in proper ducted CAI ftw when 300rwkw+

it's funny how the pod makes about 2rwkw more on the dyno.

where the bonnet is up

I have both...a pod hidden in the factory airbox...fine for daily driving...and then i rip the cover off for the track...i have done a dyno run with cover on and off but as it has been mentioned before...its still not a real world test...

And if all else fails...go grab a whore off a street corner and nick her pantyhose...

[TTT]

does it have to be Whore pantyhose?

Can't he just use the one he was wearing on friday night?

bit of pod experience, went on a SAU cruise down to wollongong. i had a k&n pod on at this time

when we got there and parked,met a dude with 1 of those laser pointers which read temps.

pointed it on my UN-sheltered pod 60 something degrees awesome.lol

so switched back to std airbox with panel filter.

so when thinking about it,i noticed Yeh the pod was awesome just after startup but once that engine bay heats up the pod warmed up to so it got a little boggy after say n hour of driving.

i prefer my car to be consistent and not depend on the weather.

only thing wrong with stock airbox is its restrictive snorkel which can be modded.

unsheilded Pod for the bonnet down power lose everytime. In the real world they suck (pun intended) without a cold air partition and feed.

I've just foam insulated the crappy HKS pods on my GTR, a few days ago. The difference around town is night and day. My intake temps were dropped by 10deg+ around town, thats a fair whack of power.

Mount the pod filter in the front bar

Mount the pod filter in the front bar

The positive pressure bouncing around between impeller and AFM is an issue though.

No mount it in the boot. Hidden inside your subwoofer box along with your neighbours dead parrot you accidentally killed with your air rifle .

the afm doesnt have to be in the front bar with the pod, leave the afm in the stock postion and run intake ducting to the front bar and have the pod connecting to that.

Its been shown that having posi pressure in the intake pipe plays with the AFM. I think someone went has far as rolling a car down a hill at 50kph and saw AFM voltage output fluctuations. SydneyKid mentioned that in some form of motorsport, one way valves are placed in the airbox to alleviate this ram air effect at speed. On my R i duct most of the air from the front passenger brake duct to a enclosed, insulated pod enclosure with a "device" of mine that equalizes the environment in there. SAU has covered this...
