I would say no. If you have a Killer Bee with the shroud, you would likely not gain much if anything. Main benefit of this intake is that it will always pull fresh air in from outside the car instead of sucking in hot engine bay heat. The shroud in the Killer Bee kit helps do the same thing; isolating engine bay heat from the front of the intake.

Tony @ Mamo Motorsports

But where is it getting any ambient temp air from......the problem with all those designs that just place the air filter up front in the radiator well is there is no real source of significant fresh cooler ambient temp air (and none of it is under pressure of course)

You get a tiny bit of cooler air from the small OEM air scoop but it just mixes with the much greater quantity of hotter under hood air temps.

This Ram Air design is pressurized with massive amounts of only ambient temperature air that is being trapped in that large triangular cavity that normally only feed the radiator and other coolers.

You get the benefit of much cooler ambient temp air and air that is being force fed into the plenum box of this design the faster you go. At triple digit speeds you would see even greater gains with this design

Worthwhile upgrade from a Vararam?

Matt Zed

My thoughts exactly!
There would need to be a test performed with 2 temperature sensors, 1 above and 1 beneath that shroud where most air filters sit.

I do believe this Ram air intake does well at speed like Tony mentioned, but the actual true off idle air the engine is breathing in screams that it has to be hot based on the proximity to the rad and oil cooler (keeping in mind the plastic shroud is no longer a barrier with this intake).

In comparison to the Vararam that also sits in that area, the opening on the VR has a beak that is a bit more forward from the Ram air SS feed location (so less likely to suck in hot air radiated from that area below the shroud).

I am interested in this intake but like others, I cannot help but wonder how hot the air is at that air filter (not heatsoaked iat readings but the actual true air temp at the filter versus above the shroud).
Time to install temp probes and figure this out.

*Although any hot iat situation probably disappears very quickly with this intake midway through 1st gear after launch.

Matt Zed

To add to my post, I noticed it was mentioned that iat temps don't go down much over the 1/4 mile with conventional CAI systems, I'll share what my datalogs show.

I have an Airaid air intake so the exposed filter sits in the usual cavity above the shroud, C6z06 so I have a functional NACA duct.

Anyways, at the launch I am at 90*F iat (51-54*F ambient)
-Top of 1st gear, iat temps are 77*F.
-Top of 2nd gear, iat temps have dropped to 66*F.
-By the 1/8th mile (102 mph) iat temps have dropped to 64*F.
-When I cross the 1/4 mile traps, my iat temps drop to 63*F.

Matt Zed

I threw my laptop inside another H/C/IM C6z06 that track day, equipped with a Halltech 103. It has the Beehive cover and the Maf is relocated to sit beneath the Beehive.
Halltech places the Maf further forward, so closer to the shroud (stock location is much closer to the throttle body).
Disclaimer, his coolant temps were 7 to 9*F hotter than mine so it affects under hood temps but here are the results below. His radiator fan enable settings are identical to mine but regardless.

-At launch, iat temps were 90*F.
-At the 1/8th mile, iat temps were 63*F.
-At the 1/4 mile, iat temps dropped to 61*F.

Just some data for us datalog driven folks to ponder over as we continue on our quest for more power with different parts.

Tony @ Mamo Motorsports

The big question is what were ambient temps??

Look.....we can certainly debate this system but there are many other systems that are very similar in their design. As I had mentioned once before in this thread I just feel this particular intake is a better executed version of that design.

Also I posted a video when this CAI was tested on a chassis dyno.....Most would agree fans in front of the car are not going to remotely work anything like ambient temp air rushing into this large airbox when the car is moving yet big power gains were seen in this steady state chassis dyno test.....both untuned and even more when tuned.

After the install in my own car, the first time I pulled out of a gas station (so moving slowly after the car sat for a bit probably getting a bit of heat soak) it ran like a scalded dog and it was immediately apparent I picked up a bunch of power with the swap. This was before I decided to relocate my IAT sensor btw.

Then I did extensive testing "in Mexico" with the results I have shared from the Dragy in the first post of this thread.....effectively picking up a half second in ET from a 3rd gear pull of 65 to 123 MPH (7000 RPM in 3rd) and a reduction of close to 100 feet to achieve that terminal speed. This isn't a reduction in a full 1320 foot burn.....in fact it was only 900 feet or so after the Ram Air SS was installed and that was starting at a silly low 3600 RPM to more simulate a dyno pull on the road which was my objective (and to eliminate a shift which could color the results).

I also have had two folks swap out the Halltech and move into this CAI and both picked up nicely on a chassis dyno where there was no real benefit of the ram air effect of this design. To be perfectly honest I like the Halltech and that had been my previous go to intake (sold dozens of them since launching Mamo Motorsports) but I was always searching for a better designed Ram Air style CAI similar to the unit I ran with excellent results in my C5 (I discussed most of this in my first post)

When I finally stumbled on old pictures of this system in my quest to find something I was intrigued and it looked like exactly what I was searching for.....little did I know they were kind of out of business at that point but undaunted I spent almost a year tracking down the people involved in this design (true story.....every few months I was trying different ways to contact them). Turns out my timing and perseverance paid off as there was a recent change in that situation and I ended up getting involved with the new owner of this company after numerous phone calls with him and first purchasing one with my own money and testing it.

Now this is what I personally run and recommend to all my clients.....you guys can benefit from all this information or choose not to but I'm confident given enough time your going to continue to see favorable results and I wont be having to type much in an effort to share what I already know

That's all I have to say about that.....LOL (Forrest Gump I believe but quite fitting none the less!)

-Tony

PS.....With my car (temporarily) still running a bone stock engine (only a ported OEM TB) and testing in the middle of the night with zero traction, a horrible 60 foot as you would expect, peddling first a bit in an effort to not blow the tires off (and spinning pretty good on the 1-2 shift), I still managed to trap 127.2 MPH. That's with me essentially not really able to put the power down till 2nd gear. I think the car would easily go 129+ at the track in this configuration if I was able to apply all the power with just the CAI. This is stock rims and full weight and a DA of 1943 feet of elevation (Southern California isn't known for exceptional air density). And that's with one run....never bothered to do another because its just impossible to get any traction and I was quite pleased with that result factoring the DA and the "track conditions". Also of noteworthiness is the fact I picked up 28 MPH from the 1/8 to the 1/4 mile with a stock engine. I attribute some of this to the Ram Air doing it's thing upstairs. Wait till I'm up over 200 RWHP with a complete Mamo top end....I'm really hoping 2023 is the year I both get my dyno up and running and mod this car. I have purposely waited to do this wanting to document this build from stock to fully modded on my own Eddy current SuperFlow chassis dyno that I purchased new and have had parked under a couple of painters tarps for far too long

Here was the Dragy from that run.....and guys....the Dragy is not a toy.....its the real deal and its works by multi satellites coordinated on your position with a 10hz refresh rate (your phone GPS is 1 hertz).
All of you that own one already know how accurate it is assuming you have used it at a few track events and compared. It replicates legit track times as good as the best equipment out there that costs 10X as much.
Its the real deal and if you don't already own one its the best sub $200 gift you will ever buy in this hobby. To those that were considering one and purchase one after reading this your welcome!!
Also take a look at how the acceleration / G-forces (orange line below) is starting to actually level off some up top at the end of 3rd and beginning of 4th gear.....that's not normal
The faster you go the less G-forces and acceleration will be present as horsepower is constant and wind resistance is increasing at an X-squared rate. The highest acceleration values are seen in the lower gears with far less wind resistance

Could it be I was picking up a little power from some artificial forced induction in the triple digit zone?!? That's my take from the hard data displayed below

Matt Zed

Ambient temps that afternoon ranged from 55 to 60*F, the data from my Airaid runs were mostly in the morning with 51-54*F ambient temps. Halltech c6z ran mostly in 55-56*F ambient temps, that's as accurate as I can pinpoint it.
I wish I logged ambient temp if there is a channel like that, I can't recall if I tried looking for it and it wasn't available, I'll check next time.

*Correction to the 7 to 9*F hotter cooler temp of the Halltech equipped c6z, comparing the logs closer shows it ran 3 to 5*F hotter than my c6z.

I'm excited to report that my Mamo ported MSD, and ported NW 103mm, and Ram Air SS was delivered today. I've followed Tony's recommendation and called Rich at Zmod to do a before and after install dyno and tune. I will report back once I have the installed numbers before and after!

88BlackZ-51

Is this on an other wise stock LS7 with stock exhaust manifolds? If so lots of guys will be watching…….

TwinturboN8

It's a 2008 Z06 with stock manifolds, I will be doing a before and after once Tony's heads, cam, ARH 2", and the mamo clutch and flywheel are installed.

exracer28

It was mentioned that there is no airflow through the radiator but there was no mention of the cooling fans. When looking at temperatures add a step to check to see if turning the fans on lower the intake air.

Apocolipse

Thank you for posting actual data.

Be curious how these temp drops compare to the stock intake for a 1/4 run.

ky13

Would be curious to try something like this on my ZR1.

Tony @ Mamo Motorsports

Note sure if the radiator shroud of the ZR1 is any different than a base C6 or a C6Z06 but assuming its close I would imagine it would add nicely to your output especially approaching or exceeding triple digit speed.

Feel free to give me a call if you have any questions

Regards,
Tony

EvanZR1

No, it won't. The ZR1 intake is completely different from the NA cars, the blower snout moves the TB forward significantly on the ZR1:

And it's even worse if you've done the LPE snout:

I wish it would fit as I've been looking for a replacement for my Kong. Guess I'll have to keep waiting on LMT to get their new ZR1 intake out.

slowtealz28

Tony, would this intake work on a C6 Grand Sport? It's dry sump if that makes any difference. I had the vararam on my C5 and the results were pretty ridiculous with 2-3 tenth reduction in et's and 2-3mph increases in mph. The grand sport just has headers/tune but needs to go back going to be doing intake, shifter, shift light and retune. It's a little more than the vararam but if there are actual gains to be had over that you got my attention. Would be happy to do some testing for you if its compatible.

Apocolipse

Anyone ever toss a map sensor into the rad shroud to see if there is actually any pressure?

EvanZR1

GS and Z06 intake are interchangeable. I swapped the Z06 intake onto my previous '13 GS (dry sump) until I added a blower.

ky13

Thanks Tony. The shroud is the same for the latter year C6s (all trims). I may be in touch shortly.


That was my planned route as well (currently have the plastic Kong intake). LMT relayed that they're going with a new CF manufacturer, so fingers crossed. I apologize for the ambiguity; I meant that style of intake. Wasn't expecting to just bolt on and go.
