More air means combustion changes, since it also means more power, and potentially emissions changes. CA is very strict about any changes to OEM configurations.

I could be wrong, but I thought he told me a while back they could use either. My test unit had the oiled filter, but he did give me the option of either and I chose oiled.

It is the only system to use a precision injection molded elliptical Airbox Tail and MAF block to ensure precise and consistent MAF sensor metering. Most others use Rotational molding and that is not a precise molding process when it comes to holding tolerances on bore ID s.
Systems like that usually require custom tuning because no two kits are ever alike.
As for airflow, the VR flows far beyond the number you posted.
The VR system also uses venturi areas in the intake system to produce a velocity spike at a specific RPM point to force air into the intake system under vacuum! We went through allot of testing to make that happen. This shows up when we do flow bench testing as well at specific flow points. We did the same thing on the DRX Camaro system to boost power under the curve to great effect. We flow test through the cylinder head, intake manifold and throttle body as one unit. We also conduct a standard flow test but those types of tests never show you the true picture.
Our web guys will be putting up the flow graphs in the next few days, as well as a flow video.
The VR TCR-7 was meant from day one to be a tuned intake system, using every trick possible to boost flow and thermal efficiency with a minimum of extra components to add unnecessary extra cost. NO CORVETTE premium!
The philosophy was: Keep it simple and get the job done as efficiently as possible to make Vararam equipped C-7s consistent and fast!
VR tech
VR,

First of all, I'm not trying to be a wise guy...I just want to see a comparison between your CAI system and AFE or K&N. You stated in your ad that your system outflows and outperforms the competition - guaranteed. Well, let's see how much hp and torque your system produces versus AFE and K&N.

Words like: high pressure zones, injected molded elliptical Airbox, velocity spikes are nice terms but how do they translate to performance.

Again, not trying to be difficult, but compare your CAI system - specifically: HP, Torque, and CFM to the competition.

The only numbers I've seen is horsepower...you claim a 18-20 increase. AFE claims 18. Why does your system have a range? Different cars, different tests, if so, what's the average?

Thanks,

Semper Fi

Exactly, show us using an oem filter after using the same filter stock back to back. Also, where does the moisture go from the cold air coming from the crack in the hood, and what kind of dirt comes from the filter sitting inside the fender area?

The oil is air sensor safe. Green filter is one of the few high performance filters to be used as OEM by several major manufacturers for this reason. They do not use a heavy silicone based oil, other companies do and this is what sticks to the MAF wires and causes codes.

A Tuned Induction system is what we produce, not just a CAI.
The stock fender volume is restrictive , so the C-7's naturally pull hot air from under the hood back by the sump tank. We pull enough cool air from the second high pressure location to aid in both intercooling of the air charge and increasing our effective plenum volume. Combining Those features along with the velocity manipulation from the internal aerodynamics of the intake systems design and it all adds up to producing some real world HP you can feel, to an otherwise stock car.

Same question as Spinkick above. Any issues running the VR in the rain/downpour?

As noted in the description:


"The VR system uses airflow from a natural high-pressure zone that draws air from Outside the engine compartment. This helps dramatically, feeding cool air to the intake system, to help intercool the intake air charge."


Some of us do let 'em see the wet stuff!

No issues at all.
I even drove my car at the start of Hurricane Harvey. Mainly because I was trying to get home in the middle of the night before the streets by our facility flooded !

Mine arrived today. Thanks for the excellent customer service. The quality looks fantastic. Looking forward to dropping it in this weekend and seeing how she does.

Got mine today. Nicely made, good instruction. I plan on putting it on tomorrow.

Quick question, is the filter pre-oiled?

Yes it is . We specify the clear oil rather than the Green colored oil.
It just looks better that way when you have a filter you can see when the hood is open.
It would look bad if you had a Blue car and Green colored filter.

For those that want to, they can buy colored dyes for the Clear Green filter oil to color match the filters to their cars.

WE stock the Green filter cleaning kits in Clear vs Green 24/7.

Do you have to use the green filter, can you use a different filter? I have a BMS filter that I like.

My C6 Vararam had a green filter and what I did was buy another one and every year in March I'd take one out and put in the cleaned other one. It made a .5 sec. difference in my car's consistent 1/4 mile times. Just saying! So I will be getting their new one for my C7.

The c7 oem intake is pretty damn awesome, stock vs the restrictions the c6 one had. I'm trying to get more data out of them on all this.

How hard is this to install. I had a C5 and put a Vararam on it. While it worked well, it was a PIA to install. Also, when/if you get CARB certification will it be possible to get the CARB sticker after the fact if I purchase one now?

I'm putting one on as we speak. Might take me two hours because I'm slow.

The Green filter was designed from day one to our Specs. It has a much lower pressure drop across it than other filters.
By "Other" I mean all brands.
Regarding the filter you have, The leading filter Brand as they say on their website prob starts with the letter K in its name.
That is all well and great, except the Brand "K" filters average a 55-50% pressure drop across their flow path. The stock paper filter has a 60% pressure drop across it.
The Green Filter is on another planet compared to those numbers.
If you change the pressure drop inside any induction system you are changing the volume and velocity at each given RPM point.
Your throwing off the entire aerodynamic package as it was designed and in this case you would be restricting the system.
Defeats the purpose !

Some of us do let 'em see the wet stuff!
NO issues , I drove my personal car In Hurricane Harvey 40 miles round trip to our shop and back in the middle of the night at 50mph. I could barely see to drive and the car was hydroplaning etc.. ( Alarm went off at our production facility)
We have been testing this unit in just about every weather condition you could imagine for 2 yrs covering thousands of miles without issue.

As an added bonus I just drove my car home in Houston, In the rain, in traffic for an hour and change today! ( washed it a couple of days ago, go figure?)
Again, no issues. It was designed to be used in all weather conditions.
There are many manufacturers who use high pressure zones like this one, some even face directly forward, and are ram air systems. examples: Mercedes Benz , Porsche, VW, Ford etc...
They use them on everything from SUV's , performance cars even the Ford F250 Turbo Diesel truck.
MB GLC example :
