nice figures.......thanks

Warrick: Was there a noticeable increase in power/performance?

[warrick]

yes.there was a really noticable falloff of performance when putting the pod on.when i put the box etc back on it was quite a bit better again than before because i had painted it with the thermal paint & put the insulation on the outside as well.the car just seemed that much more responsive & stronger,if that makes sense?

cheers

the standard air box with better filter is so much better.

costs next to nothing and is designed properly...

not something you rig up yourself..

I'll never do a pod filter again on any car I have.

there are exceptions though..

sometimes people get FMIC and the piping prevents you from using the standard air box..

this I can understand..

Sounds interesting Warrick.

My experience has been the opposite though. With the POD in it feels more responsive [aside from the noise]. I put the standard airbox back on recently just to test and it not only felt restricted [less responsive] but the max boost pressure dropped also! There were no other mods at the time - or manual boost changes.

I guess it may not be a good comparison though, between a Naturally Aspirated car and a Turbo [VT versus GTT in this case]?

I am not an advocate for pods but in my experience its a better performer over a stock airbox [this includes hi-flow panel filters too].

I have made a partition for my pod and even after several hundred kms of driving it remains fairly mild - warm but NOT hot!

[warrick]

let me qualify what i said though.for the first say 5 mins the pod did seem good but once you got the hot air around the k&n setup felt much better.it didnt seem to alter no matter what the temp but the pod altered considerably.dont get me wrong i have nothing against a pod but what i'm saying is if you are going to have one to get the full benefit all the time you need to have it enclosed with cold air plumbed in.

cheers

I would tend to agree with you, a pod on its own [like so many have done] draws in too much heat.

A nicely sheilded pod with a cold air feed is the way to go!

[Guest RedLineGTR]

talk to Al he has kit made up by EAS preformance CAI and cold air from the front bar very professional and clean setup does what it's mean to do. no heat from the engine

[NismoR34]

yes but how much $$$ did this cost?

My pod and partition setup [DIY] has so far cost me approx $50

A 'pro' setup will be at least $200 from what I have seen

One day, a nice ARC box would be nice

or one of these BMC ones http://www.autospeed.com/cgi-bin/browse.cg...duct=1004620002

Now that looks impressive.

When I put my pod on I noticed a drop in bottom end torque but once the revs got up i could feel it was a bit better (which makes sense as the pod has a bigger surface area than the stockie).

A few people have metioned that the stock intake has been designed really well (which makes a lot of sense since any R&D dept of any car manufacturer is full of $$$). So, bigger surface area + well designed intake = the way to go.

Yes?

[YBSLO4]

If stock filters are so good then why do none of the top jap garage drag cars using them? They spend big bucks on R&D aswell and at least there results show in their times

[TTT]

I never said that STOCK filters were good.

I said the stock air box.

I put a TRUST filter element in my standard box.

MINES group in Japan always keep the stock air box in their cars.

if you haven't already seen it, see if you can get your hands on a copy of Best Motoring Number 5 (I think)

Take a look at the MINES GTR...

just a quick question.. Now that you have partitioned the air filter from the heat.. what about the pipe that goes to the turbo? wont that be absorbing the heat again? Why dont you wrap that with heat wrap? I did this setup on my other car(original box, with k&n flat filter, and larger intake pipe), and it seemed to run better with the heat wrap.. ?? any ideas?

[YBSLO4]

Two sides to that as heat wrapping it will keep the hot air in the turbo resultin gin higher intake temp adn requiring better intercooler cooling, but it also shields the filter further from heat... take ya pick.

[mtopxsecret6]

I didnt actually mean wrap the turbo with heat wrap, just the piping to the turbo. On my mazda, the intercooler is some 3 times as big as this silly nissan one, and thats standard aswell. so, i guess that might affect the comparision aswell.

[YBSLO4]

i was refering to the piping dude... you gotta think about what it does with the heat but shielding the piping, it holds it in, add's stress to localised parts due to excess heat internally, however drops underbonnet temps and mor eimportantly intake temp around filter... personal decision really, if you have a good sealed box around your filter you wont need it, but good thought tho.

THIS HAS TO BE THE BEST SITE EVA

Personally , i dont think the standard airbox is upto scratch, coming from other cars, where the airbox is much bigger than the turbo pipes etc. Remember the biggest restriction is your first restriction. The over the radiator duct, is good, but doesnt look big enough to supply enough volume of air. If you had another duct coming up from the front or something, that would be nice. Time for some planning.

I rang Purple Pig, they have some form of industrial rubber(9mm thick) which i could use as a divider. Anyone tried this, it is rated 70-80 degrees, is that enough?

[warrick]

i think what mtopxsecret6 means YBSLO4 is to wrap the piping from the airbox to the turbo so the cold air in the box is kept cold all the way to the turbo before it gets heated.i think if the air can be kept as close to the outside ambient as possible before entering the turbo it must help the intercooler do its job that much better.please correct me mtopsecret6 if i misread what you meant.

Sounds good in theory. Ok how long is the pipe, maybe 30cm, how fast is air travelling? How much will heat effect during this period of travel? I dont know. Well if you can stop it , excelent, all too help that little old intercooler.
