Ok I will go first!
ALTA R56 Intake Test and Tune
Our initial test of the intake system was done with the OEM hood scoop left in place. Our intake is designed to remove this, but we wanted to prove how this was a necessary mod. So we did 3 quick runs with the scoop on and 4 quick runs with the scoop off. Below are the runs, withthe strange low boost runs removed. The dyno’s runs are redrawn over with a wide brush to show the average of the 2 runs. With no scoop, the filter temps constantly climbed. In 3 quick (10 second interval) runs,the temps were at 150 degrees. With the scoop removed, an instant 30F drop occurred, and a constantly cooling temp change started. The next 3 quick runs showed a nice change in both temp and Wheel HP. The gain was somewhat expected, and the scoop needed to be removed to get the most from the intake system.
Above graph shows averaged runs with the ALTA intake installed with and with the scoop being blocked. The RED is the same line as the below picture. Below picture compares stock to the ALTA intake.
Above graph shows averaged runs with and with the scoop opened up and intake installed!
So where is the “complete” cold air intake we might have talked about to customers?? The feasibility for a cold air intake is never out of the question, but the cost and complexity are a factor. We wanted to bring the best bang for the buck to the plate first,not scare people away. Since our intake did so well and the scoop gives perfect ambient temp to the filter, we developed our first version this way.
On a side note, when dealing with MAF (Mass Air Flow) sensors, small changes to turbulence in the intake system, can make huge changes to how the car runs. Because we are familiar with this problem on other cars, great care was taken to eliminate any turbulence issues that might throw a CEL, or make the car run too lean or rich. We can say for a fact that our intake replicates the stock MAF curve perfectly!

Thanks Adam... I'm transitioning from my R53 to an R56 which is due to arrive in a couple of weeks. Let me see if I have this straight; your CAI with the factory scoop unblocked yields roughly a 10 WHP gain, correct? What is the definition of "unblocked"? Is the current 2008 partially opened scoop unblocked or does the plastic honeycomb have to be replaced with something even more open?
TIA,
Richard

Not sure dynos of the CAI for the R56 are really necessary. Most gains are in sound and perceived HP. IMO, if you get 2 to 3 HP with the CAI and your engine breaths a little better, that is what you should expect.
If I was upgrading CAI, exhaust, FMIC, boost tubes, I would like to see a dyno plot (before and after), but in the end, it is how you feel about the mods, nothing else.
Opps, I did not see Adam's follow-on posting with dyno results. Great information! IMO, I still feel 2 to 3 HP is what I expect, if I can get 10, wow. On these 90 degree days it is subjective.

I have a stock one that I have opened up but not sure if I am going to leave it in or take it out.

Welcome to the world of turbocharged engines
Because of the differences in how an S/C vs. a Turbo works, the gains are far more significant from air flow modifications. This is true for both the intake and exhaust systems.
Thanks for the comment and let me know if I can help in anyway!

If you don't like the looks of the mesh being removed you might want to consider a replacement scoop.
Thanks again!

I've had the ALTA intake on mine for thousands of miles with no issues at all....Easy install, looks clean under the hood, power gain, simple/easy to clean the filter, and it really makes the car come alive from a sound standpoint, hearing the turbo and oem BOV...makes it sound awesome!!!

for me it was about the build of the unit. what i wanted is to have all the same companys parts , in my mind it would seem they are built to work together. im not a pro racer or tuner i dont work for alta. i had the money for the alta too so i got one. i have also done the homemade cai , with a huge trueflow foam filter and a k&n filter as well. both were noisy , the alta seems a lil more friendly to my ears on my long comutes. so i really had to pay more to get the cai i wanted. three filters, panel, foam , and k&n all with my homemade setup. should have just got the alta to begin with. but im just like most of the rest of us out there i want the most bang for my buck. i want the most power i can get. the huge foam filter i had seemed a lil too big for what i had on the car , i dont have the downpipe yet , so it seems as if the air the coming in just wont get out fast enough to work right with that filter. also with the alta you get rid of the stock undertray on the air box. that made since to me for what i wanted as well. there is alot of sand and dust and bugs and just general crap around here . so when the air is coming in through the scoop all the debris seems to go right in the undertray, with the alta alot of the crap goes down past that spot down to the ground . also i dont have my air filter zip tied down to the airbox anymore . that alone was worth it to me , nice clean installed unit so when i pop open the hood tada cool and clean looking. nothing jimmied, not that there is anything wrong with that because i did it too. i want what we all want , cool parts that make the car go faster. so get too it.

Form, function, looks, good sound engineering were the judgment points.

Keep in mind we are a retailer and wholesaler, so things are a bit different. But it should also be noted that overhead varies from mfr. to mfr. so ours may be higher or lesser than others.
WE feel the item delivers the power, performance, aesthetics and quality that folks demand at this price point. Judging by the fact that we literally have a hard time keeping them on the shelf to meet current demand, it would appear that the price has met the market.
Thanks for asking! Let me know if I can help in anyway further!
