I believe CRC makes a MAF Cleaner but it may be Electronics Cleaner. It boasts no residue and all that stuff. There are issue with K&N type filters coated with oil but I suspect that folks are putting way too much oil on their filters and that's the cause of the problem.

 

Ha. Plain and simple, it's coming off the car today! I will give a better break down later I really would like to talk to the vendor first. This is all my data taken directly from where it matters. Maybe the configuration they tested was different somehow? I do not want to bad mouth a product without giving equal opportunity to those who created it and sold it to me for $570.00

 

Hum.... Removing it eh? I have the double-piped version on my S. Certainly is a looker but as has been inferred, questionable performance gains if not losses. FWIW a Porsche parts manager/ aftermarket guru informed me that aftermarket intakes/ exhaust, etc will do nothing without a tune (which they happened to sell and I bought [GIAC]) as the Porsche ECU constantly alters variables coming into the engine so it always gets the same/ best hp. If you believe that then at best there will be no performance gains whatsoever with the Fabspeed or any intake. What the Fabspeed design gets dinged for is the hypothetical heat saturation that can occur contrasting the OEM air box. If I could interpret your quantum geekdom graphs maybe I could answer that question (I do mean that lovingly. Nerds rule the world.... Prom Kings become used car salesman!)

So it's a tune or the supposedly superior Werks 997 air box; which is stunning and pricey.

 

Ok to understand the graphs let me explain what I did. The data points you see are not one reading, some are 2 some are 10 at a particular range of RPM. I the summed and averaged a particular set of readings to come up with a data range. So when you see 700-1000 rpm most if these were most likely at a stand still or taking off or slowing down. In respect the 3k range is mostly highway. What I found to be true is on a cool morning when there is no traffic, this is cold air intake. On a hot day in traffic this is HOT air intake. Now granted the stock airbox is not fault free as the graphs show it will also follow along with engine compartment temp. but the divergence is less. Once you are moving (20-40mph) the stock airbox is superior. The air it is collecting is cooling the plastic housing vs. the CAI that is still pulling from a hot engine compartment. What's not noticeable in most of the photos is that the filter resides ~ 2 inches away from the intake port of the deck lid. A lot of temp change is happening there!
I also want to note there seems to be somewhat of a loss of airflow on hard acceleration, I am still working these graphs.
As far as the tune goes it has a fresh DME with a fresh softronics map on it!
Please note again, to those reading this, tell I have spoken with the manufacturer this is not a claim that it is an inferior product. I want to make sure that all my information is correct before I make a claim to the products quality.

 

this is interesting. I'm going to share with what i have experienced. I installed Fabspeed 997.2 Carrera S High Performance Air Intake with Carbon Fiber Heatshield on my 997.2 that i purchased about 1 month ago. I know most ppl said that there is no performance gains at all and it's just for sound improvement. Well i was curious and i bought it for relatively cheap price, after i installed mine i waited about 2 weeks for it to settle. After about 2 weeks, in terms of exhaust sound it definately increase (more aggressive) especially on high RPM and surprisingly i feel the performance gains from the intake (not huge but i definately can feel the difference). The acceleration is better than stock IMO and the sound is amazing!

Note: I wash off and clean the oil on the filter before installing. So it's dry instead with oil on the filter.

 

It doesn't affect the exhaust so not sure how that sound changed. Without data your "feel" of performance gains is what many before you have claimed - butt dyno v. data, I'll take the data.

 

OBDII The computer in your car that automatically adjusts to changes in your driving habits in order to save fuel mandated by your government. Retards timing and limits fuel for optimal efficiency...even in your Porsche. However, in theory if you free up the pump with less restrictive exhaust and an air intake you will make more power. There are bottle necks beyond the exhaust and air intake that would be more expensive to replace but for the most part these components mentioned above will assist in better performance with linear horse power and throttle response. There is enough capacity in the computer to slightly adjust for a freer flowing pump without a tune but the "tune" will definitely help. Keep in mind that even with these additional upgrade you still have to hammer on your car a few times for the OBDII to recognize that you're driving aggressively. Only after aggressive driving will the computer adjust the timing and fuel to provide maximum performance.

I've also read a lot of debate regarding temperatures of certain intake components. A good analogy would be if you had your hose connected to the faucet outside and 20" of it was in the Hot Sun and the rest was in the shade. If the hose sits for a long time eventually the water in the hose will heat up right. Once you start running the water the warm water will eventually be forced out of the hose and cool water will run freely. Remember the 20" in the hot sun...well the cold water from the tap is passing through this section so fast that the heat from the sun very little impact. Therefore, a less turbulent and freer flowing air intake should be better for performance. Obviously, heat soak would interrupt performance for a short period especially when the car is stopped in traffic.

I have noticed over the years that Auto manufacturers have started using plastics for their intakes and one would have to wonder if this improves performance. If you take the old motors with aluminum or cast steel intakes you cannot even touch the metal after the motor has been running. The plastic intakes stay much cooler. Does this new plastic help the performance? I suspect that it does. Thermal Dynamics is FM science and perhaps there is someone on the forum that can explain these affects in more detail.

 

Yes, dyno and data would be more accurate to say there's performance gains from the air intake. But i feel the acceleration and throttle response is better now than before (stock air intake). For the sound changed, yes it doesn't have anything connected to the exhaust or whatsoever but AIR FLOW does affect the exhaust sound and changing your air intake will have better air flow than the stock ones therefore changing your air intake will change your exhaust sound. And i can really see the exhaust sound is louder for sure after i installed the air intake.

 

Opening your window will change the exhaust sound too.

 

Oh well, I compared stock and with air intake installed without opening the window at all.

 

Why is the MAF lower than ambient for the low RPM on the stock?

 

I'm surprised nobody commented on this. If you're running a filter without oil that is designed to have oil on it you're ruining your motor. The oil helps catch the dirt. There are plenty of high performance filters that don't use oil.

 

Can you name those? Does BMC use oil?

 

The left hand bar shows MAF Kg/h. This is the flow rate, this is simply for comparison
so that one might be able know the amount of air flowing across the sensor.

On another note sent an email two days ago, haven't heard back yet..?

 

BMC does use oil. No problem, when I had it.
