I'm just looking for feedback on the aFe momentum intake (closed box).

They claim 18% flow over stock box. I'm just wondering if it will become a bottleneck when pushing 500+ whp. Let's assume that driver side inlets are installed, so no restriction there.

I'm hoping that someone who has them can chime in, not just theory.

I have the momentum AFE air box coupled with MMP 1.75" inlets. No restrictions. No bottle neck. I also have MMP 2" Outlets. If your goal is to get as much cold air to the turbos as you can, then you should upgrade to the AFE momentum air box or some type of enclosed air box. ECS tuning makes one, but it's about $200.00 more than the AFE version. I'm not sure it's any better than the AFE to be honest. The next level would be Dinan. I wouldn't buy one brand new. Once in a while you see them on this forum for around $500.00 or so.

I run the same intake. I don't know if anyone has the data that really compared say a 500WHP vehicle and then tried another intake to see if there were any differences in say WGDC %

I know BuraQ did some pretty extensive testing on the AFE Momentum GT and noted gains in the real world and dyno.

No bottleneck. I'm close to 500whp and on my way there, bought used DCIs twice over the years to see if the closed intake was holding anything up. Nope. This is the last compare in 2016 with the original AFE SI that I sealed up. These logs are at 20psi, but I've run the original AFE box up to 24psi on hybrids (with stock side inlets). Currently have the ECS and other than looking cool, I'd rather have the AFE since the ECS isn't fully sealed.

Red is boost, green is WGDC, yellow is IAT. Even the AFE box (with scoops) surrounding the filter on 5 sides (just the lid off) is no better than DCI for IATs (also with snorkel/scoops). The intake is either sealed from engine bay heat or it isn't. Anything you do to try to undo filters being open is a waste of time. What you save on DCI, you'll need to spend on a much better IC to remove the extra heat going in. Keep in mind, those IAT differences are post-IC, so significantly warmer discharge temps pre-IC.

Thanks guys, very helpful. It always seemed like the logical choice.

I'll wait for a deal on the Momentum.

Since upgrading to the AFE SI has your car thrown any codes

No.

No codes here either.

Is there a difference in sound or response and power

Sound - some. You can hear the turbos spool up a little more. It's a little louder, but not crazy loud.

Response - the car does have better throttle response (a little more get up & go)

I think you really see the advantages of a CAI (cold air intake) when you couple it with high flow silicone inlets. However, you will see a modest increase in throttle w/ out silicone inlets.

It's an expensive piece no question. I bought mine on sale for about $350.00 in Nov. from Mod Bargains.

If you are looking to increase the amount of cold air going to the turbos, I wouldn't start with a better cold air box. A better FMIC is what you should start with. Look into ARM Motorsports and VRSF for starters, if you don't have one. I think the better cold air box is sort of the "crowning jewel" of an upgraded intake system.

I already got the CAI, I'm just not home to install it. I'm looking up FMICs now cant decide what to go with just yet though.

For the money, if you are just DD the car, it's very hard to beat an ARM 5" stepped FMIC. Very high R.O.I. It uses the stock connections. That can be good or bad depending on who you talk to. Personally, I don't care. I just changed out all the O-rings & gaskets in the entire intake system. I have no leaks in my intake system. No boost issues. Tight as a drum.

If you get a better FMIC, you'll need a better charge pipe or the "plastic" charge pipe will crack, under the increased air flow & pressure.

Cobb makes the best one for your money, if you are wanting to stick with the stock DV's.

I had a DCI previously so it's actually less sound but it would be more sound then stock.

Response was better and by no accident good flow with cooler air.

VRSF's new 5" HD Street FMIC or 7" HD are the 2 most popular FMIC's right now. They are hard to beat with their HD cores and great price point.

I also have a cobb CP I for about that lol

I wouldn't waste your money on a Cobb FMIC. So many better performing FMIC for a lesser cost. Denser fin packs and overall better cores.
