Just got a delivery confirmation email. Too bad I'm stuck at work for another few hours. I keep telling myself that I can wait until the weekend for the install but I may crack when I get home

 

well thank god. install that badboy and take pics along the way !!

... "wait until the weekend"... psh...

 

You're not helping!

 

Well this may be tricky...it didn't come with instructions. I'm sure I can get in the intake itself in there but cutting a hole in the cowl part I'm less confident about.

edit: I also see on the DoS site that this piece is now the R55 through R61 universal CAI. Clint mentioned that when I talked to him at MITM last year, so it looks like he got one unit to work on all models. Very cool.

 

CLINT!!! Damn it man, you know I'm a fan and love blowing $$$ on The Dread Pirate! Why didn't shout out to a peep about a newer bettered DoS CAI that would fit the R56? A couple of R56 questions... Is the DoS CAI 2 that much better than the 1st and (I'm thinking) is the original firewall hole in the wrong place?

I'll be following this closely as I have a couple other things I need (prob a Forge BoV, new stripes...) Take care, my friend!

99% sure the firewall hole would be in the wrong place.

Started a new thread on the install here: https://www.northamericanmotoring.co...e-install.html

 

Hey chrunck, can you make a YouTube clip of the sound once you get it installed correct? I see how it would be more quiet than the VIP. Since its closed off from the engine bay more.

 

I can try. There really isn't much BOV sound to hear compared to the VIP. I'm thinking about removing the sound baffle, but I really don't want to take it all apart again.

 

Are there still no dyno results from this intake...?

 

It feels it's pulling a little harder than before, but it could be my imagination.

 

Anyone have any audio/video of the new CAI? Specifically the race/track version?

 

x2
it's beautiful, and the fact that it's an actual CAI makes me really itch to pull the trigger on this but i'd really like to see those dynos first....

 

I took 2 videos today, one with the windows down and one with the windows up. There really isn't much to hear from the CAI in either video, but here they are anyway. It's the performance version with the noise baffle in place.





There is an occasional hiss from the BOV, but it's nowhere near as pronounced as the VIP. I doubt someone coming from a stock air intake would even notice it unless they knew what to listen for. For reference, here is a clip of the VIP intake from autocross last year.



Not really much to hear there either. I guess it's not a frequency that the GoPro really picks up (it only picked up my turn signals with the windows up). I'll probably end up taking off the noise baffle in a week or two, and if so I'll take another video.

 

Most likely the noise baffle or at least I hope. I really loved the sounds from the Gen 1 DoS CAI and am hoping its similar.

Is using the baffle a requirement?

 

Well, the VIP sounds a little louder. You were not kidding, there is not much to hear

 

This is know doubt a beautiful piece. It looks great under the hood. The engineer side of me keeps asking the same questions and these are based on someone that doesn't install a CAI to get more sound or noise.

1. Since these are Turbo engines that heat the air anyways how important to performance is it that the air entering the Turbo is 10 20 degrees colder than the stock air box. Remembering that the stock box is in reality a CAI itself. It wasn't until the last 10-15 years that Air filters had tubes to collect cold air, most had the inlet's under the hood.
2. Shouldn't CAI's really be rated by flow? Lets say CFM at the Air box outlet at 60 MPH. That may tell more of the story? The factory tube , small as it may be is grabbing air from the front of the car so as speed increases so should air flow, but with ducting , a scoop or a way to funnel more air into it how does having an air inlet under a cowl or vent help?

I'm not trying to slam or question any HP gains statements, just trying to further my own understanding.

 

I'm not an engineer,or even really know much about any of this but everything I've read says the colder the air entering the turbo the better (air density etc) so to me it seems that grabbing more air is great as long as it's cold air, and it's anything but cold under the hood. With this in mind I opted for and aFe drop in filter. I doubt I'm receiving any HP gains or noise but perhaps a better flow of slightly cooler air entering the turbo since I still retain the stock airbox.

 

I won't go too in-depth on why this design is superior to the open-filter designs, but I will give you an idea on how much power is actually lost on a fully-built N18 with an open filter.

We actually gained back more than 12hp/tq by putting the stock intake back on and removing the open-filter intake setup. Two different open-filter setups were used, both suffered the same fate.

I had originally, much like ke3ee, assumed that since the intercooler was cooling the charge air, the intake temps did not matter. This was not the case, however.

We've had the DoS on for a few days now, and there are some appreciable differences. I will post some sound clips, which of course will sound far different from a stock setup, but overall we're quite happy with the gains on this turbo. The stock airbox simply could not supply us with the needed flow.

 

YES audio please. Woohoo! Thanks again.

 

As promised:



and



Watching in 1080p or 720p will give you better sound, by the way.

 

Same ol' DOS sound I've known and loved!! Thanks Theta! Ordering pronto.

 

Looks like Clint and DOS are off the grid till Nov 1st. Bummer! Oh well more time to fill my mod coffers!

 

I removed the noise baffle today, and it's a good bit louder. I took another video, but the GoPro still doesn't pick up anything. It's not as loud as my old VIP intake and not as loud as whatever aftermarket turbo Theta is running, but I like the added sound.

 

Remember I also have the race version, which might be making it sound louder since it's getting air directly from the cowl.

 

That's the version I have too.
