you're gonna need more than this friend All my new tricks are ordered and install should start in a month or so...

I should be dialed in for the good weather track days

 

I just want a 13 second timeslip on my hands from CSW when i go there next time. I will get u back though in a year or so, don't worry.

 

Why "may" you post them, is there a reason you dont?

Also,
can you guys do a test comparing intake temp with the Z-tube and this intake?

 

I'd like to add more data that includes temp. probe readings at idle and cruise as well.

The Z tube can be included in this analysis.

Regards,
PFE

 

Like some have already pointed out, it appears the only real advantage to this intake is filtration. It might flow the best, but it's already been proven that the stock airbox (assuming a relatively clean air filter) can flow more than enough air for a VQ35DE at 7000rpms. "Q45tech" did this calculation years ago. Dynos for the Stillen CAI, JWT POP, etc constantly show little to no gain which further proves the OEM intake does it's job quite well.

Additionally, the stock airbox becomes slightly pressurized at speed and this improves throttle response and keeps ambient air flowing through the intake tract. By making the filter open anywhere to the engine bay, you remove the pressurization effect.

Finally, heat soak is a big deal, but you guys are putting WAY to much thought and effort into heat soak with regards to intakes. The reason being, when the intake tract is heat soaked, the intake manifold usually is as well. Additionally, when heat soak becomes a problem, it's usually hot outside which means the density altitude is already bogging down you car. Plastic is one of the better thermal insulators hence the reason every automaker including Ferrari uses plastic intake tracts. Essentially, the ideal setup is to keep the intake manifold and intake tract as cool as possible, but what works against the car, especially a G/Z is the fact that the engine bay is very hot thanks to bay being larger enclosed on all four sides. There's a lot of heat build up in there at a stop or at slower speeds. Simply put, a cast intake manifold mounted to screaming hot motor enclosed in a box is going to be a hot place. You engineer an intake tract to be as cold as possible, but there are way too many factors working against you and at best, you might be able to lower intake temps at the IAT by a coupe a degrees on a hot day.

I don't know about your cars, but when the weather is in the 60s and below, the intake manifold and intake tract stay cool to the touch during normal driving. Further proof that ambient temps influence underhood temps far more than a particular intake setup.

I have a VERY hard time believing this "new" intake is going to make any more power than any other intake for these cars because I'm seeing nothing really new here other than a rectangular intake pipe. I will be extremely surprised if anyone sees more than a couple HP gain with this intake. I've been wrong before, but I'm fairly confident about this one.

 

Currently I am using a KN cone filter in my custom intake, and would love to try your product out. Is there any way you can get me the measurements in circumference and diameter so I can see about fitment on my 2003 g35 sedan.

 

DaveB,

Agreed on heatsoak, thanks for pointing that one out. i've been keen on that for a while now. people hate on my ARC intake pipe since it's metal. i always tell 'em that the upper and lower plenum are gonna be much bigger "hot spots"(no pun intended) for heat soak. even the guys running the plastic Kinetix V-plenum can't beat the heat. so i say it's not really a factor we have too much control over. as for the R2C filter, i see what ur sayin' BUT i will say that there isn't an easier to clean and maintain filter than the R2C on the market today. they've really done their research on this one. they use the same tech that we use in our Military HMMV air filters. i can tell you from experience that those can really take a beating and be brought back to life w/just an air hose and a few good shakes.

 

posts from a different thread - but regarding this filter... I'm a little miffed


PPE... whats up??? Why did you say this was a direct fit replacement for Stillen?... Tell me this is wrong, because I'm about ready to slander this product if what was posted is accurate... especially based on what you have posted previoulsy.

 

When the original fitting was performed on the Stillen equipped G35, the plastic at the lower front of the box had been trimmed. Not knowing this, the filter was produced to maximize performance and capacity based on the room allowed in this application. Certainly no intention to mislead anyone. The fact is that the lower area of the box must be trimmed for clearance of the R2C filter. The comparison photos made this fact clear. Apologies for any mis-information but I'm certain you will enjoy the performance and unmatched filtration of the new R2C technology. That said, I'm here for rebuttal.

 

Sorry, Stillen owners... I've got the JWT setup, fit fine. Please don't be discouraged by a lil' trimming, it's still easier to install than a CAI. here's something i wrote on another thread:

 

Hey Everyone,

My 04 G35 was one fo the cars R2C used for their measurements of the new intake.

Also, my G was the one they used to figure out how to fit the Stillen filter:





The only thing that needs modifications is to cut the plastic under the power duct attachment, and the filter fits just fine (BTW, a simple pair of heavy duty sheers will do the job).

For all of you Stillen and JWT guys, the R2C filters are great and highly recommend them for replacing the traditional gauze filters currently utilized in your intakes.

Here's more info on the media used for traditional intakes as opposed to the R2C's material...

PFE, are there any updates on a possible drop in for the stock air box. I am sure you would get alot of business with that product if it filters and flows well. All we have right now are stock, Amsoil, K&N and a few other hard to find filters.

 

A close up to what you are referencing would help… I know what/where the power duct is - however, I’m not entirely sure of what you specifically you cut… before and after pictures of what you modified to make this filter fit would be great. The pic you posted doesn’t show what I’m asking about.

 

It's pretty clear what you need to cut if you take a look at my intake thread. the powerduct lower portion along with a portion of the stillen piece needs to be cut away to make room for the longer filter.

 

link & pics would help...
