Vroom vroom..... It's comical to imagine it...

what hes probably getting at, without saying it is that your car will run differently on different days. was the weather the same on both days? post the slips if you can, id like to see what the DA was when you ran.

The LS3 or L99 engines can only use so much air... once you meet that goal, anything more is overkill. And I think all of those CAI's meet that goal.

I think we agree with that for most straight or dogleg pipes and filters, but the next step is heat abatement. Heat soak on the pipe, ambient air temp of the engine bay, outside air temp...etc.

What Denis said is true, your car runs different on different days and temp/humidity will affect that drastically on a NA car.

CAI worked pretty hard on keeping the surround insulated from the engine bay.

No, he was being a jerk, which is typical of him. Anyways, here is the info. I've got stacks of time slips from this summer. These are two slips that I grabbed randomly. I can tell which CAI was used because I never broke 14.0 with the Volant.

The first slip is after I'd visited the strip about three times. The car was performing poorly and I couldn't figure out why. I was actually PM'ing a very knowledgeable member about it during this time. At first, I thought it was my fault and something was wrong with my driving. Something was just killing the car's performance, especially on the top end. Either that or my car was just a slug. It was very discouraging.

My only engine mod was the Volant, so I took a close look at it. I noticed that the PowerCore filter only breathes through the round end, and not through the sides like other filters. I also noticed that the round end was partially blocked by the plastic fender well. It was like a light bulb went off. I knew I'd found the reason for the poor performance. I called Rodgers and ordered the Z28 intake that day.

The second slip is my first run ever with the Z28 CAI. (I actually ran a 13.2 at some point, but this slip is fine.) If I hooked up, the car typically ran 13.2 - 13.5 every single time, no matter what the DA was. (DA was actually worse on this night)...Once again, with the Volant, I never once ran faster than 14.0.

Conditions were similar every weekend - hot and humid. These slips were prior to my getting headers and a tune. Besides the CAIs, the car was totally stock. I was running the same street tires and wheels on both nights.

The slip from July 3, 2015 is running the Volant w/PowerCore filter. DA 2106 feet, Relative Density 93.98%

The slip from July 31, 2015 is running the Z-28 CAI. DA 2700 Feet. Relative Density 92.33%

I've since been tuned and added LT headers, so the car is a lot quicker now. I am not saying the Z-28 intake is the best one out there. I am saying that I think any popular CAI would've given a similar improvement over the Volant w/PowerCore filter.

The Roto-fab intake continues to be popular because it does everything CAI should. First and most important, it adds power. The dyno sheet attached shows a peak gain of about 17 HP on an otherwise stock SS 6 speed Camaro. Secondly, you gain an awesome sound-especially under hard acceleration. Third, our intake looks great and you can customize it to your tastes.



CAI design and function is much different than most people believe. Subtle design variances can create huge differences in performance. Our intake is actually "tuned" to the stock vehicle calibration. Simply stated, if your intake isn't designed properly, you may end up with a great sounding intake that performs equal to or perhaps worse than the stock system. With the Roto-fab CAI you get the power gains from cooler air, superior air intake capabilities (as compared to the stock air box and snorkel) and a large filter combined with adequate air box volume. However, all of the aforementioned design qualities would amount to nothing if the intake was not also carefully designed to function properly with the engine management system. On the other hand, the same design features listed make our intake a great choice for those of you tuning and heavily modifying your car.
Lid or no lid? For the end user, this one comes down to personal preference. As a manufacturer, we make this design decision during R & D. When possible, we prefer an effective seal to the hood. This design gives you all of the benefits of a lid while maximizing the usable air space around the filter. Keep in mind filter size and air box volume become more important as more power additives are introduced. That's one reason our intake is so popular with the supercharger crowd as well as some of the best tuners in the country that are making big time power!
At Roto-fab, we do all of our plastic molding as well as our metal fabrication in-house. This gives us the unique flexibility to design and manufacture our products in the method we think is best for a given application. We have intakes with lids-we have intakes without lids. We have intakes with metal air boxes and we have intakes with plastic air boxes. We go with what works!
In addition to all of our design features, we offer you the ability to customize your intake to your car and your tastes.

Granted this was on my G8 GXP but very simular platforms. Rotofab swap on the dyno.

First I had a K&N with the chrome tube and it was ok but not great. No noticeable gains but just the cool sound.

For a while I was looking for a new cai system and the CAI Inc. package looked good. But as I thought about it more and more I just didn't like the idea of having take those little screws off to inspect or clean the filter.

I always liked the roto-fab look. So when the supercharger went in I got the roto fab to go with it. Bigger diameter tube, bigger filter and no sealed top. Easy to maintain. I also really like the carbon fibre look. Matches the supercharger engine covers.

oh wow, so the DA was actually worse when you ran the Z/28 intake and you cut that much better of a time? that's impressive! I appreciate you sharing the numbers. .

like I said, if this intake was available when I was in the market I would have picked it up.

When I switched intakes, of course I was hoping for an improvement. But, I was very surprised with how much difference it made. The Z-28 intake most definitely helped my car. As soon as I installed it, I noticed that throttle response improved, and it seemed to idle just a little bit smoother.

The Volant w/PowerCore filter is a nice filter and a nice housing... (I think it probably filters the air better than any other filter on the market.) It's just not a high performance filter in the configuration they offer for the Camaro. I do wonder if the Volant system would've performed better with the wet filter they offer. I think the biggest flaw with the PowerCore is the way the fender blocks part of the filter. It has a small breathing surface to begin with, and the blockage makes it even worse. It really needs to be redesigned.

Just from looking (I've never used one), I think the Roto-Fab unit would perform just as well as the Z-28 setup. It looks like a high quality piece and everyone seems to really like them. It is pretty cool that the LS3 and L99 respond so well to a simple CAI upgrade. It's easy and cheap HP.

Very nice! For those of you looking for an air intake now and considering a supercharger in the future, we offer an upgrade kit for many of the aftermarket superchargers so you can use your existing Roto-fab system with your new supercharger.
The Roto-fab systems generally gain about 35 HP over the stock air box with a drop in filter! We've heard this time and time again. Yes, it is basically the same system which picks up about half of that with an NA car. However, as air demands increase, the benefits of our intake increase as well
We offer upgrade kits to accomodate:

Magnuson 2300
Magnuson Heartbeat (less than one week from completion)
Whipple
E-force
SLP 2300
