Anyone evry tried further modifying their stock airbox by cutting/punching holes in the front of the airbox itself, as opposed to jus leaving the top part open? I figure that since air is travelling from the front(grill) to the back (engine area), that making access holes in the front of the stock box would allow air to travel through a lot easier.

GAB + holes in front of stock box = MGAB (Mad Ghetto Air Box)Any thoughts on this?

 

wouldn't that make it similar to a short ram intake.. such as a berk or frankercar? and how would this supply air any warmer than just the GAB alone? i figure this setup would have 2 means of acquiring air: (1) through the stock snorkle, and (2) through the newly perforated "warmer" air holes in the stock box..

i think it may work.. has anyone else tried this already?

 

But isn't the regular GAB hot air too?

 

STFU and stop posting in my thread if u think it sucks..

 

True CAI’s dont perform well on our cars. Vast research has been done and in fact GAB have been dynoed and proven to give around 9whp. There is also a thread on her discussing a experiment testing engine bay temps. If I can remember right and someone double check me the temps weren’t all that varied. With the original questions I have holes drilled into my airbox. I have yet to do the GAB mod, but I can say that the holes I drill did make a slight difference in performace. Also there was a drastic difference in the department or sound. It definitely sounds meaner. I don’t know if this would be so evident with GAB already being in place. There are some different schools of thought on the hole drilling. I think if you were to do ones to the airbox itself not the filter hanger like I did. Perhaps orienting the battery a different way (for example vertically instead of of horizontal) might be beneficial. This is just my two cents.

 

Simple answer to this ^. DON'T READ IT. Who gives a flying flip about what you think of his thread. Dude asked a question, not your friggin opinion of it.

 

I deleted all of my prior posts. There you go, tear it up!

 

I slaughtered mine... no difference besides sound.

 

That's because the "true CAI's" you're referring to are not TRUE CAI's....Injen-NO. Berk-NO. Frankencar-NO. These are all warm air intakes, just like the GAB.

The only TRUE CAI for the Maxima is the Place Racing/Cattman - neither of which are available any more.

Take it from someone (me) who has had:
-stock
-Frankencar/Apexi
-GAB
-modified GAB
-Place Racing
......the PR (i.e. TRUE CAI) produces more power throughout the entire range than ANY of the other intakes. No, I don't have a dyno. But I switched directly from GAB to PR, and the difference was clear as day.

 

to answer your question - YES, several people have tried that setup, with mixed results (ranging from more high end power, to no gains, to loss of low-end)....

 

POP Charger FTW .....



All runs done with headers and mentioned intake. Of course they're not on the same day


Green POP charger
Dark Blue POP charger run # 2
Red GAB
Blue Stock

 

Dang! Adding a POP charger let you gain 20+whp?

 

intake gains are considerably magnified with headers though, generally.

NMex...you need to put a PR setup in and see what that does for you. Also, was the car "hot" or "cool" during these runs?

Short-rams really cause considerable power lag at low end after you've been sitting in traffic for 15 minutes...whereas the PR setup does not.

When in cold weather or with good airflow, there's not much of a difference.

 

btw, you were only putting down 212whp with stock intake and headers with a VQ35??? That seems wicked low. Hell, I put down a tad under 200 with GAB/Y/E only on a VQ30...

That lowest run looks like it should be a full-stock baseline for an A33B, not with headers

By that chart, you're saying you gained 22whp with intake vs. stock air box?

 

You mean like this?


Yes, it sucks hot air from the engine bay, but my engine likes it.

The MGAB definitely sound meaner than stock, and probably adds more hp. My butt dyno says about 3-5 whp.... yea, not much.

 

hes automatic...the #s aren't that bad if you ask me

and yes, he gained 22whp from an intake...and race fuel

 

Stock 4AT's A33B's put down 194-196, 6MT's lay down ~201-204 (208) highestn a DJ.

The 2 POP runs were done about 5-7 mins apart.

The GAb comp was 3 mins (time it took to slap a hangar in there)

Had like 3-4 g of 100 unleaded + 12g of 91. Dyno place is ~ 75 mi away, so who knows what the mixture was.

I really do need to try the PR set-up...

 

oh, just of note...I am not using the "full" PR settup....just the downpipe - although I tried out the midpipe section, it seemed to be a bit weak on low end. I then replaced it with the stock "accordian" resonator piece linked to the MAF and the PR downpipe, and that appears to be (far and away) the best combination for power through the entire range.

 

I saw your set-up from an eralier thread.

I also think that's the best set-up. Stock resonator + PR = teh win.

I have proven that the midpipe has an effect on the curve, and the resonator gives the smoothest line.

The midpipe helps things above 5.8k, but gives a dip @ 5k ish. This can be see on stock Z33's and A33's that have a straight midpipe.

I still need to tune my a/f... Hopefully I can prove a few more things then.

I also have some dynos showing what heat soak can do... Runs back to back, then 3 mins after...

 

I did this to achieve more air flow through the stock intake:
Cut lower portion of intake baffle off (3" in diameter)

Added a screen to stop any unwanted items from entering the opening.

Reinstalled. Looks OEM and adds a slight deeper intake note.

 

all I know is that today it was 68 degrees and crisp weather....damn the car felt wicked powerful today after all these hot days

 

That second pic looks like a MAF

 

thats pretty cool nismo, i like it
not sure if it actually works though
in fact it might work against u since air would flow in the front and out the new opening

u should start ur own thread on this snorkle mod
how does ur max sound with it?
any noticeable improvement as a result?

 

the shape of the stock snorkle still seems to restrict the flow into the airbox even after it is gathered from the 2 sources of air.. very interesting tho.. show me some results

 

It's actually the lower portion of an old MAF cut off. Good call!!

 

Thanks. I thought about that too, but the intake sucks the air in at WOT, so this is definately giving it more air.
I did, but not much of a response and I can't seem to find the thread anymore. Deleted?
The only noticeable difference is when taking off at WOT, the car appears to accelerate a bit quicker than before. I am able to break the tires easier than before. But then again, my butt dyno might be out of calibration.

 

I was trying to figure out how I could get the rectangular intake piping from the snorkel to the box to be larger in diameter, around 3" piping, but have not taken on that task yet.

No results to show. Just my opinions. It appears to be providing more air to the intake and the intake sound is noticeably different. Not like a WAI or CAI, but louder.
