He has the schroud propped open. He is getting all kinds on cold air with the "hood closed" to his K&N

 

I didnt draw any conclusion, just said that I was skeptical as the only time I've seen it perform in person it performed very sub-par and the owner of the vehicle was very unsatisfied with it.

I stated in my post there could've been something wrong with the car...but again, he would've known the difference of before and after, and he was not happy with the gains of .1 and 1mph according to him.

I will be going with a K&N with open shroud and then adding a vette-air scoop...the construction looks 100% better on those items AND it doesnt look so cheap when you open your hood and see the vararam in there (it comes off as a very cheap looking product to me)

 

That's still not even close to resembling any kind of ram air effect.I doubt popping the shroud a little will get him all that power.All the air does is dance around in there.There's no direct shot to the throttle body/maf;And,If one is going to pop the shroud anyway,why jerk around with wannabe's LIKE THE vette air thing(notice how it resembles the mouth on the VARARAM?)??Just get the real MCCOY...VARARAM,CALLAWAY,LPE..ETC! It just kills me that for all this time the powers that be are telling everybody about the fabulous gains w/ the K+N,HALLTECH etc...and then what do they do??THEY INTRODUCE A SNORKEL MOUTH TYPE THING that's a dead ringer (although smaller) FOR THE vararam SETUP!!!There's only 1 way to fly,and K+N ,and those other BIG FILTERS ain't it!But,to each his own!Try an experiment...run a VARARAM for a month,then A BIG FILTER.See if you don't notice the IMMEDIATE DIFFERENCE in the SOTP meter,or lack there of when you switch.I did,and boy,it felt like I was driving with 1000 lbs.weight behind the car.

 

Great research Mr. 11secGP

Now, if you were to PM or email the guys who ran with the K&N and some of the misc users, they will tell ya that they have or had the vette-air onboard during those runs. In fact, looking at the list above, 50% of them are Vette-Air customers

Did you know: Vette-Air has powered more 9sec, 10sec and 11sec
Z06's than any other CAI kit? Vette-Air now has powered one of the fastest LS3's as well! COINCIDENCE??? I don't think so.

Look, we are not as BIG or have the fancy marketing scheme as the other bigger CAI companies, however, we are helping cars go faster. There is no secret that cooler denser air is one of the key components in making more power, and the vette-air scoop helps in that dept.

If you are on the market for a simple yet effective "cold air scoop" and don't mind modifying the shroud (the only way to get cold air), then please consider the Vette-Air. For only $129.95, if money well spent.

If were to do a search, you will see that many of the Z06 and quite a few C6 guys as well are using the Vette-Air system and running fast times. Don't fall trap to fancy marketing schemes, ALL CAI systems out on the market today work...period! Are some better than others? Sure, but by as much as let's say 10hp over the other....I don't think so.

Bottom line, if you want cooler air, you will have to get it from outside the engine bay, and the Vette-Air helps with that. So does the VR, Honker, Vortex, LPE. Remember, just because a product has a big name behind it and cost much more, it does not mean that is better than everyone else.

Hope this info helps

Thanks,
Carlos

Wow. Why the hate? Dyno numbers do not lie. The K&N filter is what LG Motorsports uses on most of their installs. I am putting down 501 RWHP now with a cam, headers and underdrive pulley and it's all breathing through the K&N. If you don't believe the dyno, I don't know what else will convince you.

 

The Vette-air is the way to go if you are stock or with a K&N intake
or similar intakes. way better than a ugly proped open shroud,gives you a ton of cold air1
Plus Carlo's is honest service! prop's to Carlo's anytime!

 

On this forum its:
"To each his own unless you have a K&N"
"those damn K&N guys are fools for liking hot air and not following ram air technology."
"Its ugly and mine is more pretty looking when you lay on the ground."

To the K&N haters why dont you give it up and prove your combo with results?

For the time being, Ill stick with performance data and track results. If the K&N is used by most of the fastest Z06 guys that might mean something. If the K&N is used by most of the highest C6 bolt on dynos, that might mean something.

 

way better than a ugly proped open shroud

Any air cleaner has to protect the air path from the elements and provide adequate airflow to the engine. IMO the stock C6 air cleaner housing does both jobs just about as well as anything else. The only problem is, for performance of lowering IAT, ambient air flow from in front of the radiator is blocked by a shroud. I got a propped 3.25" open shroud on my 07, and I think it looks just fine to me (along with the price!), though one has to be on their back on the ground to tell what it looks like!! This includes the Vette-Air too. IMO, you dont need to spend hundreds of dollars for a piece of plastic from whoever, just spend a few minutes cutting or opening your shroud.

 

OK I don't drag race (sitting in the staging lanes getting hot) and have never had the car on a dyno but 1 thing I consistantly see is people saying if you have a K & N /Halltech etc.. it breathes nothing but HOT underhood air. This is simply not true. I don't care about an extra 2/10's in the 1/4 mile or whatever. I love just driving my car and in normal driving the engine does get cool air. If it doesn't explain how after driving about 70 miles total yesterday on all types of roads and several stops if you pop the hood immediately and feel the intake it's ice cold. Yes I do have a Halltech Stinger SSM and no modified shroud or Vette-Air. Not only is the Halltech cold but so is the MAF,TB, and the metal clamps holding them on. Now it was about 60 degrees but I have tried this many times and even in 80 degree weather things are still cool. Not as cold as they were yesterday but still cool. If the engine heats up to 200+ degrees and it's only sucking in hot underhood air how can my intake be so cold? Because it's NOT sucking hot air. Sitting on a dyno with the hood closed doesn't account for the air coming in while the car is moving down the road. Now please I'm not trying to say that the Vararam doesn't work or make your car faster or that 1 system is better than another. Maybe the VR is the best system if you do drag race. For the kind of driving I do my Halltech is fine and from my own experience I think it is getting cool air.

 

I've kept track of all my 1/4 mile runs on my 06 C6 A6. It's been a very consistent car in the 1/4 because it's an auto. I ran it with the K&N inlet for quite a few runs. I also data logged it and noticed I was getting warmer air than I liked. At the strip this wasn't too bad as long as I didn't hot lap. I also cut a flap in the radiator shroud and did a poor man's cold air inlet. However testing at the drag strip showed no improvement.

I then put on the Honker knock-off, the Xcelerator cold air inlet. Logging the Xcelerator versus CBRF4i's car that still had the K&N showed that the K&N would get down to the same temp (CBRF4i has done the Halltech mod to let in cold air), but the Xcelerator got to the cold air much quicker.

The proof of the pudding for me was the drag strip. I averaged very similar runs (60 foot times & similar weather) and I picked up .8 mph in trap speed with the Xcelerator as compared to the K&N. These were corrected trap speeds but I used similar weather because my car tends to correct to higher traps speeds the hotter it is outside.

Take it for what it's worth, but I do have data that has convinced me that the cold air inlet is worth around .8 mph in trap speed which is around 8 rwhp. Not much, but it's something.

That being said, the K&N is a high quality piece of hardware. It's great and you don't have cut your shroud. You can NOT go wrong going with the K&N.

 

You make good points Mr. Siffert, but...

Okay, first, the Vette-Air is constructed from a three part fiberglass material. Fiberglass will not get flimsy from repeated cooling and heating cycles like plastic.

Second, the "propped" shroud idea works but not as well as you may think. Remember, for maximum power, you want air velocity! Air volume is good but air velocity is much better for power producing.

The Vette-Air, due to it's mounting location and structual shape, it forces the incoming air to rush into your filtration system. Remember, the same air velocity theory is incorporated into cylinder heads porting programs. Head porters know that air velocity and NOT volume is what gives you greater power.

Now, some may think my explantion is OFF, and if so, I challenge any one to give it a try on the dyno and at the track. Take your stock AIS or open-filter element equipped C6, propped the shroud then slap on the dyno with a fan blowing as hard as possible. Do the same with a Vette-Air board and after that, tell us your results. Repeat this test at the track and provide results...you will be surprised.

Thanks,
Carlos

 

Unfortunately, while we have actual hp tuner scans of the data indicating the benefits of cooler air flow no one is paying an attention.
