Airbox Vs Pod Back To Back Testing

[Lithium]

Cheers, I guess that detail is what we are after and is going to have to help the situation What I'll endevour to do is get before and after on the dyno and see what happens.

Abu - thanks for the input though the example you give sounds like it doesn't assist what we are after, unless you did the runs with the bonnet down?? What I am talking about is when the bonnet is down and you run the risk of heatsoaking everything... I'd like to know how much can be gained by going from an exposed pod in the engine bay to a decent cold air setup.

Just pulled a R32 off the dyno back to back testing pod and airbox:

HKS gt2535, Z32, PFC and std airbox.

with airbox and consecutive pulls lost power to the point of detonation, had to remove 8 degrees of timing comapred to first run to stave of det..

fitted pod, alloweed 10-12 degrees more timing after consecutive pulls and made 12-15rwkw more....

real word and a regular SAU'ers car.

did the airbox/pod have a cai?

Awesome, thanks for that. Bonnet up or bonnet down?

Changing the intake pipe to silicon intake pipe and putting a 3a air filter on it. Will make a partition up on the weekend or even a full aluminum shield and maybe some sort of CAI feed from the bar then bring it back

See if that makes a difference

did the airbox/pod have a cai?

Standard air box with paper panel filter, no CAI

Awesome, thanks for that. Bonnet up or bonnet down?

Down

9/10 people dont have proper set up CAI systems.

they just have a fat pod hanging right in the endgine bay doing the worst job ever.

i dont see how a airbox can possibly out perform a properly set up pod setup. especially at high hp apps. airboxes just dont suck as much air compared to pods.

only times i hear ppl have gains is when they are comparing it to a naked pod sucking hot air, which is no suprise if it loses power.

What do you consider a proper pod setup?? Or a naked pod setup?? My pod filter sits where the stock airbox goes but has no shielding at all. Yet.

I cant see why you would put the pod in the engine bay if your worried about inlet temps... stick it down in the bumper where it can suck on mostly ambient temp air and be done with it.

then it sucks up water and all other types of shit

you shouldnt be taking your line thru water like that anyway...

[DRD-00F]

Not to mention it's a "filter".

All you should really need is a splash guard...

[DCIEVE]

I cant remember the last time I hit standing water deep enough to submerge my pod (would have to be over a foot deep to ever touch the filter). That being said I have a splash guard on the rear (same as used on the back of a std side mount intercool) and a baflle in front of the filter so it cant be directly hit by water coming though the opening in the bumper or splashed by puddles etc.

If your planning on driving through creeks/shallow rivers maybe buy a snorkel

I will assume bonnet down but was the pod shielded at all?

[abu]

I run no guard lining and GTR front bar, on a bad raining day I get water in the engine bay (behind the head light where the cooler piping goes through the floor)

Weather thats because the bar has a lot of openings, weather its because I have no guard lining, I don't know

All I know is if I had a pod filter behind my bumper, my engine would be fkd by now

[RBwhatever]

I find that even just having the cold air intake routed towards the pod it routes in a lot of dust and bugs very quickly and clogs up that area of the pod filter. Surely having it exposed behind the bumper will only amplify that.

I've got a breathable stocking over my CAI now and it filters out a lot of dust and bugs and it doesn't take long to have the stocking start catching everything.

defiently not ur setup sorry buddy lol.

enclose the pod away from inlet temps, and feed it outside air from the bumper or something with some sort of tubing.

especially on cold nites you FEEL the difference.

everyone here should know how hot air and cold air affect turbo performance

We had a Silvia who's SR20 my workshop rebuilt come back in, which had its pod down at the bumper... It was around that time we had very heavy rain at the start of this year.

Pulled it apart and found number 3 cylinder rod was bent like a banana! Cannot compress a liquid!

No shallow river or creek driving, driving to work on the road during heavy rainfall period

Lowering the intake charge temp as much as you can, as often as you can it all you gotta aim for

So keep it lower before the turbo, and after the I/C. What happens from the turbo to the I/C is minimal as the air isnt there long.

R33 GTS-t airbox is much better than the R32 one from what i can gather, it also the point of the panel filter inside the airbox is of as much importance as the airbox itself

Shit filter, shit flow which would give problems mentioned above which is something to think about considering GTR's with good panels flow 350rwkw without a worry

[DCIEVE]

f*k of course if you just chuck a pod behind the bumper with no shielding its going to get wet... shield it, run a guard liner and you wont have any problems.

Dunno about you but I have a 4" intake and a filter to suit, its not gonna fit in there without chopping stuff. I had an intake like that with my old Honda and it worked superb though, and in that size (~3") you I am pretty sure AEM did a fitting which basically blocks off the air flow if a restriction appears - ie, filter submerged.
