Bone stock and take off those times is excellent for just intakes and nothing else as the previous comment said.
This mod is even better when tuned. I had the EC before and after intakes and it made an even better difference after. It's x2 even better if you have downpipes or an exhaust with bigger than OEM piping
reason being that the turbo can get rid of gases faster therefore suck up air faster (spool up)and that's where the super short travel is beneficial.

The noise I was talking about is towards the end if this clip.
now with the music on u don’t really hear any good or bad noises from the intake IMO
I don’t think the intake is causing this but what is it.
most sounds good & strange are coming from passenger side.
maybe driver side is better insulated?

Great times for bone stock, as well as stock with intakes! Most stock times that I have seen on here are in the 12.6 to 12.8 range. My PFL coupe 12.7x stock. Wish I had done an untuned comparison with my BMS intakes (which I cannot do now that I am stage 2).

So just to add to the performance information about the intake. This type of a mod is a "compound modification" that is to say; the more you add to your car, the more the intakes will see a benefit.
example: those with downpipes or exhausts with piping that is 2.75" or larger (oem sports or PE is 2.5" OD)
with the above> because the exhaust gases can exit faster and the turbine wheel has the "exit" portion of the spooling up process covered in terms of being free flowing-Our intake with its super short travel (3 inches) can now suck up more air because on the other end there is no bottleneck.
this is amplified even more of course with a tune where boost targets are met earlier because of the super quick spool. If there was a way to put the filter directly on the turbo we would have found a way, instead we added an elbow to the inlet which was the next best thing.
Last week I personally rode shotgun with a c450 with our 2.75" Performance exhaust replica full exhaust with the OEM intake, and then with our F.A.I
This is completely with no tune whatsoever, and the car violently surged forward more aggressively vs. the ride I took with the intake only and stock exhaust back in August. If anyone is in the tri state NY area with downpipes or a FI exhaust we will strap you on with a borrowed kit from a tester customer of ours and you will see this first hand.
has to be 3" downpipes or the FI exhaust for this offer and more than 2 cars to volunteer.

Have you tried to reinstall the stock setup and see if the noises go away? Or as some have said, was something not seated properly with the new install? Have not heard that noise ever....

That's an amazing time for only an intake .
my car is stage 2+ I'm thinking it will benefit greatly with this.

Haven’t put stock intake back on to see about the noise.
but I guess I’m looking for ideas as to what it is
it only happens between 30-38mph, it happens at 1/2 throttle not wot, and the noise seems to happen when built up turbo pressure is released. I will admit I don’t know the inner workings of my car very well.

Sounds and appears like the car is either fluttering the wastegates or more likely from how it sounds the diverter solenoid valves to regulate boost. Hard to tell but the stock intakes would likely muffle sound so much that you'll not likely hear it if it's still happening with stock intakes. It could just be how it is normally and you're just now able to hear it. It doesn't quite sound like compressor surge but then again I'm only familiar with how compressor surge would sound when letting off throttle completely.
I've noticed some people have had faulty boost control solenoid valves that make random vibration like sounds when at idle. They didn't seem to notice any other symptoms such as issues with boost, just the sound it made at idle.

Thank you for your insight!!!
what does this mean for the car?
What do I need to keep any eye on, should I go back stock and bring to dealer ( still under warranty)
Thx

Well, I can only speculate but I would start with reinstalling the stock air intakes for a while and try to replicate this scenario. You likely won't hear the sound since stock intakes are designed to be quiet, but keep an eye on your boost gauge. The boost gauge was fluttering in sync with the sound it was making so you can watch for that.
It can only be potentially harmful to the turbo if this was compressor surge... which is a condition when there is more boost pressure being generated than the engine can take in (high pressure and low airflow). The pressure starts pushing itself backwards through the air intake.
Whether it is compressor surge or the ECU regulating boost in an odd manner using the diverter valves and/or wastegate.. the boost gauge would likely look the same as it is - fluttering around while on it's way down. So it is best to check what happens with the stock intakes back on first. But to me it is odd nonetheless since you're just cruising along and it's shifting through gears. Hopefully it is not a symptom of using these intakes on an untuned ECU.
