Hcr32 Standard Airbox Over Pod Filter?

[abu]

Hey

Thinking about putting my air box back in my car. It's a HCR32 with few mods, usual shit.

I've got an APEXI power intake on it at the moment and it runs fine, no complaints its just that now the car is a bit more cop bait due to how it looks and I don't want the hassle of defects etc

I was just wondering if air box does/will do the same job as a pod filter without causing any restrictions.

I haven't seen/read much information about HCR32 air boxes but have read a bit about ECR33 and BNR32 air boxes being quiet restrictive due to the lower section design.

Anyways just wondering if reverting to the standard air box set up with a good panel filter will do the same thing my pod is doing without losing any power/response etc

I want it to perform the same just without the possibility of a defect.

Any one had any experience?

Thanks,

Abu

Butcher your airbox and hide the apexi power intake inside...but if you really want to go with a panel filter...open up the feeds to the airbox and i will perform just as well...

Attempted to fit APEXi power intake but thre is no way it will fit.

Its way to big. I think you can fit a HKS foam style filter or a TRUST air-inx which slight modifications to the box but they are foam based and they are a bit average quality compared to a Apexi P/intake.

Which section of the air box do you open up for better flow!?

[mobman_69]

Cut the front part of the bottem box out and inlarge your cool air intake and you will run a treat

The airbox's flow pretty well, i doubt you'd see any restriction with your level of mods, you'd get less heat soak too than with pods which is always good... but no cool noises.

lol yeah I get a nice flutter at the moment with the plum-back pipe and BOV blocked off, but I cbf with cop trouble.

Being on P's with a very 'limited' amount of demerits left I don't want to take the risk.

At the end of the day I want it to go fast and be that little bit quieter, rather than it be slow and sound good.

Its looking like the air box will be back on tonight, and the Apexi P/intake up for sale.

It will fit...i guarantee it...although the filter will be crushed ever so slightly...i know because thats on my car at the moment...

It will not really give much of a gain over the airbox for now but it does stop the cops from hassling me...and when i hit the track or strip...i just remove the airbox cover...

If you want to open up the airbox...you can open up the base and run another pipe to feed the airbox....

Oh what it does fit!?

You must have hacked it good, I lined it up and had a look if it would fit but the way I wanted it to sit it wouldn't have worked.

As you said though, I don't see it having much more gain over just a panel filter anyways, because bottom line is that its still inside the air box.

I think I will cut the bottom of the box out a little more so it catches a little more air. The air flow is pretty good from the bar to the engine bay but there is a little mod you can do in the R32s which allow more air flow into the engine bay.

I just done the opposite to what you're about to do lol. Last week i took off my stock airbox with K&N high-flow panel filter and replaced it with an Apexi Power Intake pod.

I can tell you now that i noticed a significant difference between them. With the pod it feels much more responsive and less restrictive than with the airbox, and the car definately pulls harder for sure.

I hacked at all the air feeds on my airbox when i removed my front bar for the FMIC so i could make an CAI for the box, it helped, but as i said the pod has been significantly better.

I'm not worried about the heatsoak as i hardly ever hit boost on hot days - The only downer on the pod is more unwanted attention, but as of now i'm content with my setup but i'm keeping my airbox in storage in case of any troubles.

Cheers,

Steve.

Hey Steve

Whats going on?

Yeah I had my air box on when the car went in for compliance, and I was driving it around a fair bit. It did feel different to when I had the pod filter on originally but I don't know if that was because I had the stock exhaust on as well.

I run 12psi all day and it ran that with the air box no issues, but it feels stronger with the pod filter. Don't know if that's mentality thing though?

I have noticed in previous cars that the car ran better with the stock air box over a pod filter.

My air box sits perfect with the intercooler because it uses stock engine bay piping (return flow), no issues there at all but I will cut some of the bottom of the box out for better flow.

I think I might just try it for this week with the air box, I will notice a difference anyways since I have had the pod filter on for a quiet a period of time.

Just don't want the cop trouble man, car draws too much attention as it is because of the ride height and big cooler on the front, plus its loud with the straight through exhaust. I can get away with the rest probably just the pod is the only thing that could score me a defect.

At 12 psi i really wouldn't bother so much...just whack the airbox on and open it up slightly...

I run the car at 18-19psi daily and still have the pod hidden in the airbox...

[TTT]

old arguement this.

my personal experience is that with RB25 turbo on RB20 engine and 11 psi, pod or stock air box made no difference on the dyno.

155rwkw with both.

the main difference was in traffic etc.

the air box got no-where near as hot and the car always almost as punchy after stop go traffic as it did on the freeway.

with the pod it was heatsoak heaven making the laggy rb20 feel even doughier.

just use the stock box. Even with stock filter..

Awesome, I will open it up tonight and fit it all back in with a new panel filter.

Any hints on what to cut/remove to open it up more?

Thats pretty much the answer I was looking for.

Appreciate all the replies.

i've been using the standard airbox with a cold air intake running from the front bar and feeding straight into the snorkel.

a couple of weeks back i put on a huge 6" M's K&N pod and instantly noticed sufficient lag, even with the cold air intake pipe in place. i've always been against pods because of heatsoak.

my next mission is to cut a hole with a holesaw undeneath the airbox and through the chassis, and place a 2nd cold air intake pipe there. might even replace my filter with a bit of stockings for better air intake.

Thanks for your reply.

My car did sorta feel more punchy with the air box, but I reckon it struggled up top. But agan I wasn't sure if that was because of the air box or the stock exhaust.

wtf thats awesome!

Thanks for that mate.

struggling up top would have been the stock exhaust mate.. lol.. you'll find out why when you remove the stock dump pipe and compare it to your aftermarket choice.

Haha yeah got the turbo back on now but when I put the exhaust back on I put the pod filter back on at the same time so could never compare the differences.

Rev's nice and free now, could be a little better with a better flowing cat though but thats another story.

Anyways, I will put the air box back on tonight with a new panel filter so see how that goes.

fkn prick putting that piece of shit in!

Hey Abu - I've been alright mate. Let us know how you find it with the stock airbox on without any modifications done to the box.

I guess it might not increase HP with a pod (i guess it also depends on what brand/type as there's some shoddy ones around), but for me it has definately felt more punchier, especially in the higher rpm range for some reason i have noticed (BTW, i'm still running stock boost with cat-back + FMIC).

Interesting none-the-less.

years ago I also posted some results I got with a JAYCAR temp probe using pod, shielded pod and airbox in different conditions like traffic, 60kms/h, 100kms/h etc..

If you feel like searching...
