I found it through New Level Motor Sports.

Price seems on par from what I have paid in the past. Yeah shipping sucks but that's what you get for living in Alaska. Let's hope they actually have it and they ship it out tomorrow.

The donaldson powercore filters started showing up in the diesel truck world a few years ago. Major advantages were flow levels did not degrade as the filter got loaded with dirt, and the design could trap and hold significantly more dirt than conventional pleated designs. They are oem on the ford powerstroke and scorpion diesels now, and have something like a 60k change interval. Good technology, not reuseable though, you will have to buy a new one eventually.

Well it's in the hands of FedEx. Should be here Thursday sometime. I'll keep y'all posted.

PS the Jeep is really liking the cold air (19-30) we have now up here. Lots more power than when it was 50-60 out.

i wonder how much more air this thing will allow to be pulled by the engine since the inlet hole is basically the same size as the current snorkel hole with a K&N. I also wonder how much louder this will be over my K&N drop in with stock guts. Because I like that, but louder is better. who doesn't want a snorting cherokee at WOT?

The baffles located in the tubing and not the inlet size is what holds back the factory intake and by eliminating those baffles by use of new tubing I feel a significant rise of air flow will occur.

I have to say looking at volant intake the inlet to its box and the intake tube itself are much smaller than the stock intake (the stock TB connection is 3.5" and the stock airbox connection is 4.25") and the snorkel they have looks much smaller than the stock one as well. Also, knowing that that stock air intake flows 580 CFM and that 580 CFM will easily support 460 hp makes me very skeptical this will make more power than the stock intake does. The most restrictive part of the stock intake is the snorkel for the airbox not the I would like to see someone do a before and after dyno to see. As for sound this intake will not be much louder than the stock airbox due to the way it is constructed with the closed airbox so if anyone wants this for a sound mod they may be disappointed. The sole reason I built an intake for mine was for sound. The one I built was able to flow 1200 CFM but since the engine flows only 480 CFM max the extra airflow makes no difference really.

Here are the specs. I think the airbox has a 4" connection and the tube into the TB is a 4.5 to 3.5 reducer. The airbox also looks like it might be open on the right side (fender side), even though the top is closed off. I am not sure how you can say the snorkel is smaller, since it fits into the same opening as the stock snorkel.

Terminator2 are you worried about heat soak? Looks to me like your are just sucking it in at a faster rate now. I am guessing its just a sound mod. And I assume you do not off road with your jeep at all. I know living up here in Alaska and just driving on the dirt roads out here makes a open element oil air filter clog up way to fast to even justify one.

Looks good though nice work. Just has all the same problems that the Bwoody has as well.

No heat soak issues at all actually. I did tons of testing and I discovered that moving the IAT from the heat soak prone metal intake tube and into the airfilter inlet fixed the heat soak issues and still gives an accurate inlet air temp reading. The filter is far enough from the engine and close enough to the snorkel inlet that the IATs are 4* above ambient on the average which is actually lower than the stock airbox by about 6* because the IAT is located right above the radiator in its stock position so heat soak is an issue at the sensor. As for clogging up it is a dry filter so it stays really clean. If I do any mud or water crossing though the stock airbox draws about 8" higher than my intake so the stock airbox goes back on in those situations.

I think it looks great and will function a lot better. That is why I got one. His WAI looks nice but I doubt functions any better if not worse.

Any way I will report on it tomorrow night when I Install it pics may be involved.
 
#26 ·
It functions really well compared to when the IAT was in the metal intake pipe. It does not heat soak like Bwoody's intake!!! The stock spot they put the IAT is right where radiant heat from the radiator will hit it which will heat soak the sensor. My warm air intake as you call it showed intake air temps that were as low or lower than the stock airbox due to good filter and IAT positioning. So is it really a warm air intake? Just trying to keep you guys from wasting $300 hoping you will gain significant power over the stock airbox. It looks nice but honestly so does the stock airbox compared to so vehicles out there. I did my intake for sound mainly but I also wanted to preserve stock like power, drivability and response.

Well this is my 4th Hemi. And Every CAI I have put on has helped. Sure not a huge difference but noticeable. Combine that with a tune/exhaust you will def notice that.

So if you are saying the engine can only handle 4xxcfm then why do you have one. That for sure decreased the performance of your engine. We could argue for ever on this and every forum does

I guess to each there own.

It definitely did not decrease performance (data logging 0-60 times with my HP Tuners scanner proves this) and I already said I did it mainly for sound. I knew what the stock intake flowed (580 CFM) and how much air a 360 bhp engine ingests at 5200 RPMs (approx 36-37 lbs/min or 475-485 CFM at 70*F) so as soon as I crunched the numbers I knew not to expect any big gains from an intake. I tune for a living mostly LS GM cars and LNF turbo Soltices, Skys, Cobalts, and HHRs. I know a thing or two when it comes to tuning and making power. My first version of this intake definitely had issues with heat soak due to the position of the IAT and I had 120-130* IATs when fully warmed up. Once I moved the sensor out of its giant metal heat sink and into the filter inlet IATs dropped 50* or more and performance came right back with throttle response maybe a little better than stock. I also have a ported TB and intake mani so those might be helping as well. I have straight through magnaflows and a H-pipe in place of my front resonator as well. I need a tune but a tune will not increase airflow on a NA vehicle just the efficiency which which it uses that air to make power (A/F and timing are critical)

The stock intake per terminator2 flows 580 cfm. At standard temperature and pressure 32* @ 14.5 psi (sea level) spinning at 5800 rpm (factory red line) the Hemi needs 578.99 CFM. So it appears to me that unless one raises the operating RPM or increases the volumetric efficiency then we are all just really wasting our money. I believe that the hemi's true upper limit operating range is between 6300 (conservative) and 6800 rpm. I came to the conclusion of this by doing some simple auto math based off of the components the engine is made of. I believe that if the Hemi's piston speed is kept between 3800 fpm and 4000 fpm then the engine should not let go. I do believe that running piston speeds over 3800 fpm will cause premature wear on the motor. If we take (3800fpm x6)/ stroke 3.58 = 6368RPM (4000fpm x6)/stroke 3.58=6703 RPM.
At 6368 RPM the Hemi will require 635.69 CFM and at 6703 RPM the Hemi will require 669.22 CFM @ standard temp and pressure an increase in 56.7 CFM and 90.2 CFM respectivly . My point is this. Until the codes are cracked and we can raise the rpm limit to the Hemi's true performance limts instead of being stuck with the ultra conservative factory limits. Than we are all wasting our money including myself with the K&N style Drop in filter. Now this is all based off of top end performance.

There is however a potential for across the board performance increases at lower RPM's due to the after market CAI tubes being less restrictive at lower rpm levels. So again unless your increasing the operating rpm or increasing volumetric efficiency you don't need more CFM you just need a smoother path to deliver the CFM. This is why a lot of guys running drop ins do not feel any performance change unless they have made some other mod like a chip, and why guys with bone stock systems feel a change in performance with the CAI.

Those airflow calculations seems very high given the output of this engine. Volant intake looks nice. I would like to see someone do 3 dyno pulls of a dynojet with the stock airbox then put on the Volant intake and do 3 more pulls. Average the 3 stock pulls and the 3 pulls with the intake and overlay the HP and torque curves to see if there are any significant gains. Butt dyno never tells the correct story. My dad has had 5 hemi rams from 2003-2010. His first two were SCSB 2wd with 3.92 gears and LSD. One was an 03 with a Magnaflow muffler and a K&N drop in filter the other was an 06 with a aero turbine muffler, K&N intake, and a hypertech programmer. I used to log his trucks 0-60 just for the heck of it and I found that not only was the 03 faster by half a second or more 0-60 but the 06 was consistantly quicker by a few tenths 0-60 with the stock intake down to the filter vs the K&N intake tune or no tune. MY 06 GMC 5.3 was faster with the stock airbox vs the airaid intake I had. My 02 Dakota was faster with the stock airbox vs the airaid intake I had. The list goes on.In my tuning experience unless you are running forced induction, a cam, heads, LTs, etc that often times the stock airbox does just as well if not better than an aftermarket intake. Sound wise though nothing beats the sound of a V8 inhaling though an open cone filter IMO. I hope this intake proves me wrong but manufacturers have a history of showing up to 30 whp gains that were never replicated by anyone who bought and dynoed those same intakes. All that being said the Volant intake looks 10 times better than Mopars and the ones the airaid and K&N tend to build.

Sorry for my technical ramblings. :threadhijack:

I do like the volant systems. I have used them for years on everything from mustangs to trucks. I can't wait for some pics of some installs. If the fit and finish is as good as previous versions I have had, then it will be well worth the money. This will more than likely be my next mod as it appears to offer the least amount of restriction combine with the most filter protection. In the past they have offered cold air "scoops" for their boxes. I wonder if they will be available for the WK2?

Interesting conversation.

Please correct me if I'm wrong, but I have always thought that the Intake stroke on a NA engine is parasitic to performance.

ie. I see it as like one of these squirt guns:



Where the engine has to pull in the air. The easier you can make that job the less work the engine has to do. So yes, that squirt gun can currently support 1GPM, an adequate stream to get people wet, but if you make the squirt hole bigger, 1 GPM is much less work and therefor much less parasitic keeping you from tiring and allows for more participants in the wet tshirt contest.

Well it came today and I got it installed. Very nice piece. The instructions blow but not to hard to figure it out. The drivers side facing the wheel well is all open to make room for that huge filter. What a nice filter that is btw! It's all sealed off otherwise. No hot air from the engine is coming in. My test ride was not the best to see the performance increase tho. It was blowing 80mph with blinding snow at my house. Nothing strange for up here but It does not allow for mashing the throttle. However I put it in sand/mud mode so it would not pull the power when my wheels spin and it sounds amazing. This might be the first car I ever own that I do not put a exhaust on.
I only have a few crappy cell phone pics. I will post up in a bit.

Gonna ditch the bwoody Moose?

I think I'll still wait to see what the Mopar one looks like, but it can't be too much better than this one...

Based on my measurements with the Bwoody intake (granted very crude), heat soak and IAT sensor location really didn't matter. The big thing was that it was sucking air from inside the engine bay rather than through the stock snorkle location. Looks like the Volant unit handles that situation nicely. I'd even put the Bwoody intake back on if there were a way to get it to suck air from the outside of the vehicle...

Here is a picture of the 2011 Durango at SEMA with a mopar intake that I assume is exactly the same as the 2011 Grand Cherokee will look.
