Stagea Air Deflector

[gtst25]

.

Tomorrow, if it is a hot day, I will test the inlet air temperatures to make sure the scoop is functioning. I have 2 sensors and temperature guages, one I will fit to the front of the grill and I will stick the other in the inlet air stream inside the snorkel itself. This will test that only ambient temperature air is getting to the airfilter. If it is successful I will post up the templates for the air deflector and the scoop, which you could use without the air deflector if you wanted.

Hope this is of some use, Happy New Year

Looks great SK

Been in Egypt so haven't been able to log on 'till now to have a look.

How did you go with the intake temp test?

Cheers!

Everday I had time it wasn't hot, but yesterday was a ripper 30+ degrees and I was driving around in traffic and on the freeway.

Stagea air snorkel scoop temperature test.

The Ambient Temperature (AT) sensor was placed in the air stream just behind the grill.

The Air Filter Temperature (AFT) sensor was placed on top of the air filter in the standard airbox.

The testing process was;

1. I parked the car facing the sun for 2 hours.

2. I then drove at 50 kph max without stopping for 1 minute

3. I then drove at 70 kph max without slowing/stopping much for 5 minutes

4. I stopped with cars around, at the traffic lights & checked the temps just before I drove off

5. I checked the temps again after 10 seconds of driving

6. I then drove for 10 minutes at up to 110 kph, these are the minimum temps I saw

7. I then drove around a parking lot very slowly for 1 minute and checked the temps as soon as I stopped

Test AT.... AFT

1... 33.7... 64.5

2... 32.5... 40.3

3... 31.8... 35.4

4... 32.5... 61.4

5... 32.8... 52.5

6... 31.8... 33.2

7... 32.2... 55.0

My observations on the results;

Anybody who thinks its OK to have a POD with no heat shield and no ambient air feed needs to read this.

I was measuring the temperature of the air itself, not the temperature of the things that the air goes through/around. Just because the airbox itself is hot, doesn't mean the air inside it is equally as hot.

It doesn't take very long for the air to heat up, but it takes a lot longer for it to cool down.

I am satisfied that the scoop design works as intended

Pictures

The first is the temperature sensor probe inside the airbox

The second is the ambient air temperature sensor probe, I taped it behind the grill during the tests

The third is the temp displays themselves, they are handy things to have, cost ~$35 each from Jaycar. They don't react super quickly to temperature changes, the probes are quite large, they take a little bit of time to cool down themselves. So I think the actuals results of test 5 are quite a bit better than what the gauge showed.

Hope this is of some help:cheers:

dang it, i need to get rid of my Pod

[someonestolecc]

Very good details S-Kid. Thanks.

Notching another tick up near the case to get off my ass and fibreglass a proper enclosed box up instead of using a dodgey peice of rubber/aluminium divider.

Ima pick me up one of those jaycar things today.

terminal i don't think he's saying you need to get rid of your pod filter you just need to make sure they are enclosed or are at least cornered off to the side so that the rest of the engine temps are not going to affect the temperature of the air being drawn in through the pod filter...

[Terminal]

yeah, i think that's what i meant, but in the heat of the moment i wrote something stupid. I'll be looking at an FMIC soon anyway, so i'll do something about it then

[mcnamg]

yeah sk just means that you need a deicated feed to the pod direct and the pod needs to be sealed off from the engine bay

[Brazen]

Hmm Ive been reading a lot of different opinions throughout the various skyline forums about POD vs HKS panel filter kit...

Again being the mod noob - more questions sorry

Could someone please tell me best option if I am only aiming for decent (not strip racing) performance improvement... Ive heard panel filter kit is around $100... whats the price difference for everything for a good pod set-up sealed off? whats involved in sealing off from engine bay and will it be legal? Whats the diff between just a pod VS a power air filter thingo - and are they the ones that produce the nice acceleration sucking sound that turns heads (not BOV - i know that sound and dont like it). And then again whats a cold-intake kit-different again???

If price difference is not unreasonable, and power thingo does do that sweet sound and up the performance,then I am envisaging a Abflug bonnet vent feeding air to a power pod thingo set-up (if legal) - but I obviously need more info on seeings i dont even know the terminology or difference!!! Please explain

[mcnamg]

the good thing about the panel filter is that all you need to do is fabricate the air defelctor and fit a performance panel into the airbox with a pod you need to set up some ducting to direct air onto the pod itself as well as creating a partition of some sort to seal in the pod to ensure that the air that is entering the pod is still cool. From what I have seen there is not too many effective ways of sealing the pod in other than creating a partition yourself that seals the pod from the rest of the engine bay if you do a search in the main forums page you will probably find a few good threads discussing this in detail. I know I have read a couple of threads and there may be some more options avaialable to you

Good Luck

[Brazen]

Good info - thanks Glenn!

And just to confirm though - only pods make that sucking sound - not panel filters?

[mcnamg]

they both make the sucking noise but because the pod is not enclosed it is much more noticeable ie there is not any sound shielding around the pod to cover the inductuion noise

[Jay95R33]

Brazen, I'm running a high flow panel filter in my Stagea and I can hear some induction noise, but it's no where as loud as the HKS pod I used to have !!

Easy, get a pod *with* heat shielding

[Gary2]

Just to add something extra to Sydneykids idea.

I removed my airbox then covered it totaly in foam rubber with the reflective foil on one side, you have to do it in pieces and use a heat resistant glue but I managed to drop the airtemp between inside and outside the box by 15+ deg.

Now all I need to do is Sydneykids idea and drop the temp some more.

Another gold star to SK.

I have copied Sk idea and made my own air deflector. I have not finished it yet but have nearly got the main part done. I have used 3mm type of plastic, not sure of the exact name. So far looking good and when finished I'm just leaving it black which looks good I think.

I still have to make the bottom scoop then seal off my POD air filter.

To buy the materials I looked in the yellow pages and found a shop that supplied plastic materials. I got them to cut a 100mm by 40mm and had heaps left. Only cost $22.

Edit:

After degreasing engine bay the nice black air delfector is now light black and looks a bit ugly as the chemicals eateninto the surface a bit.

That black plastic looks good, almost standard

Gentlemen

Would somebody like me to do a 'commercial' version of this air deflector?

SK?

Gents?

If you do, you can have mine as a template.

I would Lurve to uses yours as a template.
