Wow that looks great!

nice!

Love to see numbers with a legit filter :P

Define "legit"...

okay okay.....I think I MEANT more of a traditional aftermarket coned filter for performance. Not saying this drop in version isnt getting good #'s, I'd just love to see a comparo

The design of this intake would not accept a cone filter. It was never designed to be a cone filter intake... If it was, I probably could have banged something out in less than half the time, at half the cost, and it would just be on par with the competition at best.

Don't let the term "drop in" fool you. The filter is a high performance flat panel filter, and it just so happens to be the same shape as a stock filter.

Perhaps a visualization is in order. Air takes the path of least resistance... By design the intake has a flat panel filter, facing the direction of flow... Essentially the straightest path you can get (minus the 90 degree bend in the intake tube of course). So we know that the air flow has to make one turn in the 90 degree bend, why add another turn to the air flow path by going with a cone filter?

Think about it. The air on a cone filter is being pulled in all the way around the filter, and it HAS to turn yet again to enter the intake tube... The other problem with this is that since the air is coming in from all directions, it can cause unwanted turbulence in the air stream...

This is an airflow analysis that I did in SolidWorks early on of a 4" intake tube w/ a 90 degree bend. The filter was even modeled with a 1.5" velocity stack smoothing the flow into the tube.



Is it accurate? I'm not sure, but it's exactly what I was thinking would happen in my head, and it's the reason why I went with a flat panel filter, rather than just making another cone filter intake.

I can make a box with a round hole, and stick a cone filter on the end up the tube, and I can tell you right now it will be worse than the current design. I wanted to do something different, and I have. And consequently, it also works very well as it was designed.

Awesome visual. I completely understand your theory and don't really disagree. If it WERE that obvious, why are more companies not doing it? I don't mean that in a way to challenge you or say your wrong.....simply asking. I really like the look of your CAI so far and waiting to see the final version :P
I may have missed it but 2 questions. Is the underside of it open to where the air scoop would benefit or is it more closed up? Does the resevoir need to be relocated?

I don't know why no one else has done it. The assumption that a cone filter flows more air than a flat panel filter because it has more surface area has been floating around for years, everyone and their brother has heard it at one point or another. And it's easy! Stick a cone filter on the end up the tube, BAM, high performance intake . You don't see the Camaro specific OTR intakes using a cone filter. They're trying to get the straightest, shortest flow path possible, and also going for a "ram air effect"... Pretty tough to ram air into the flat end of a cone.

It is open so a scoop can be utilized if desired, and the reservoir does not have to be relocated. The recent testing was done without a scoop, and with the factory washer bottle in place, you can see the bottle in the pics, and the video.

One of the independent testers will be testing this intake w/ a scoop vs the stock intake on the dyno.

Very interested as I'll be SCing my 1LE with full bolt ons and trying to decide on what CAI to go with. I'm taking a heavy look at the "dress" appeal of them as well.

I really really really want a one-piece tube that goes from my whipple or SLP TVS2300 SC into the "box". Any ideas if you will be offering that and powdercoating options for the piping? :P

At this point in time it's really tough to say when, what, or even if supercharged options will become available. I'm sure they will in time, but I have no idea what they will look like. I imagine a single piece intake tube could be sectioned together, but it's really space dependent. I'd have to get access to a SC'ed car to assess the situation.

What will be the price on this item?

[Jason@JacFab]

Anyone interested to know the pricing that we have in mind please send me a PM, as I am unable to discuss pricing in this section of the forum.

If you build the OEM location CAI RIGHT, it doesn't matter what shape your filter is, as long as it's free flowing. I know the Halltech has a HUGE velocity stack encorporated onto the end of the pipe. Their filter has a spike that directs the air to the intake mouth but it's smoothed by the velocity stack as it enters the tube. I'm thinking the CAI brand has something similar but not as pronounced as the Halltech. The reason why the Camaro OTR's don't utilize a cone isn't because a flat panel is better, but because you can't physically fit one in the space provided. Halltech uses a oval filter in their Corvette intakes and they are known to work extremely well. Isn't the VR filter a oval shapped filter as well? I know they were at one time but they may have changed.

I won't go into the "ram air affect" since it's a marketing gimmic and seems that any obstruction in the path of the air will nullify any affect you could possibly see.

I do like the look and construction of your intake though.

You may or may not know this but Jason has purchased and "flowed" most of the popular intakes out there. He knows exactly how much CFM they can move.....Different filter shapes, tubes, etc etc.

If I still had my SS, this is the intake I would get.
