Honestly, with the filter taking air in the sides and the front of itself, having the heat shield (helps), and the fact that it sits right in front of the stock air entrance (which is obviously quite a high flow area) I don't think intake temps will really rise a whole lot at all if they rise any. Now temps will DEF. be higher sitting in traffic on a scorching summer day. But, in all honesty, this Z will NEVER see those conditions. And even if it does, how many people are racing in standstill traffic? I guess some do, but not me. The "ram" tube only lowers the volume that flows into the engine bay and will probably only add 1 or 2 HP over, say, 80 MPH. This is a fact with a lot of other cars. All it is really doing is closing up some of the space that air has to flow into the box/filter/whatever. I think the only thing that might be worth doing is blocking off the opposite side of the bumper between the radiator and the bumper (not in front of the radiator) to restrict flow into places the filter isn't going to be able to get it. But I am not going to do that because that may alter the air flow in and around the engine bay and could possibly retain more heat. Do I know this for a fact? No, but it makes a little sense, yes? Anyways, I guess I am a proud member of the my350z Christmas club as well! Still waiting on some out of towners so hey, why not post!!

 

Jason.........I think it would be interesting to see what the JWT does on the dyno while attached to the stock tube it was designed for. Any chance of a dyno with this comparison?

 

Judging from this thread and other research I've done, it seems the stock airbox is pretty damn good. Maybe just a K&N panel filter would be the best option. Unfortunately it doesn't do anything in the looks department under the hood.

I was hoping for a consensus but there seem to be quite a few options that have varying support.

 

Well you're welcome to buy my K&N since I am selling it after buying the Popcharger. 30 bucks shipped.

 

it will be attached to the stock tube... id put the snorkle on for fun...

BUT!!!

I just had a customer in today with the MINES AIR DUCT!

now that i saw it in person i NEED it! Before, i just wanted it.. NOW ITS A NEED!!!!!!

 

I am not familiar with the Mines air duct.......where can I see one? Is there a link?

 

First off Bro, Do not under Estimate our Texas Summers. One of the first mods I did to my Z was a JWT POP Charger ( there wasn't a CAI out of the Z yet in Nov. 02) I loved the increase of low end torque and the Growl. but as soon as the Temp started to rise (over 80) I could REALLY tell that the engine was being heat soaked and loosing HP. So I pulled off the POP and put on the AEM CAI. Major Difference I gained 3hp over the pop Charger but lost 2 lbs of torque. After having both, The pop Charger is good for the Low end But a CAI is Betteri for the Hi end and over all.




That is Because you Engine Does not Look as good as mine does

 

I did a little experiment with the Injen, Nismo, JWT popcharger and stock air induction set ups. Yes I for some unknown reason have three different air inductions products for my Z? I used a chip to read data from my ECU. Specifically I read the intake air temp and flow rate, along with some other data. Here is what I found: The Nismo/AEM, and Injen CAI restrict air flow compared to the stock set-up. However these CAI do result in slightly lower air intake temps, especially after the car is warmed up and has been running for a while. Otherwise, they are restrictive. I tested all three intakes under identical situations right after another. This was a major pain in the Butt to do! Right now I have decided to go with the JWT popcharger. From my test results, it is clear the this setup produces the most air flow and keeps the air cool just as well as the Injen, Nismo & AEM setup. Tonight I added the Crawford Pluenum and my air flow is off the charts! I can definitely feel the increase in HP at higher PRM, especially after 5,500K RPM. I have been meaning to post my techical results for people to stab at and hopefully bring more insight into my experiment, however I need to get a scanner to post soem of the data.

Here is a snapshot of the air flow form the stock setup.

:: Hope everyone can view Bitmaps, becuase this is all I can pst for now.

 

Well, Chazzg, I've lived in Texas all my life and do not underestimate any weather in Texas. The post after yours speaks for mine AND you took me a little out of context. There is more to my post than what you quoted. Yes heat soak will play a part in low speed hot summer driving. That is almost nonexistent in my Z driving life. Not every product is for every person.

 

Here is a graph of the Nismo/AEM CAI intake with results for Air flow. I also have air intake temp, etc stats. I have a ton more data than this, but this is all I can figure out how to post at this time. Injen results were slightly better.

All runs were done on a closed track, at the same speeds, the same day, under the same conditions. I made sure the I made every run as identical as possible. These runs show results under all differnet types of conditions, i.e. WOT, hard braking, 100MPH+, etc.


I am not an expert on any of this, nor am I challenging any manufactuer claims, this is just the data that I happended to get from my car, so take it for what its worth.

Here is pic with JWT popcahrger and Crawford Plenum.

car and driver did a test a couple of months ago and a Z equipped with the jwt popcharger (the only one out of four Z's N/A, turned the best 0-60 times)
it also had the stock exhaust.

 

I did not mean to quote you out of context. I did read all of your post on this, And I did feel the same way you do now, We will pic up this Discution in Aug. If your Right i will put my JWT POP back on.


I have had a taste of your Z driving life, and yes I agree at 110+mph you will not get as much of the heat soak that I did.

 

When is the next meeting for ZCoT?

 

Well, We have a "Get together" On Jan 3 but the Next Real meetting will be on Jan 15th @ Juan's Hacienda in Plano, 15th and 75 , at 7:30 but we all get there Early.

Could you explain what Air Flow Rate (Ibs/s) is a measurement of?
Looks like pounds of air per second.
