3.3TT BMS Stinger Intake System

[brancky3]

I was thinking intake would sound better when floring it . You hear the sucking sound for a bit asayou get going then it goes away until redline . And can't hear it as your go through gears .

Thanks, baby turbos! This is why I'm surprised some people say intakes are sooo loud when in reality there's only a difference down low.

My thoughts exactly

Are these sealed from the engine bay?

No but they utilize a metal heat shield to block radiant heat from the engine and the filters mount directly in front of the location where the OEM air funnels fresh air in.

No offense but that's only half correct.

Just to clarify, they do have a heat shield but the filters are actually mounted & pointed toward the back of the engine, not directly in front of the OEM air inlets. This design will naturally draw in more hot air since the filters are right next to the turbos. The heat shield will help block some of the hot air, however unless the back part was completely sealed off this will still draw in radiant heat from the turbos.

However, if anyone is concerned about that they can get thermal heat shielding sheets(https://www.amazon.com/Thermo-Tec-13575-Adhesive-Aluminized-Barrier/dp/B00029KC2K) and just wrap the backside so it makes a sealed barrier between the turbos and the filters. It may not look professional but works wonders and make a huge difference in IAT.

The filter is right next to the OEM air inlets, I'm not sure I understand your point of view here. (see air inlet at the bottom of the pic below). It doesn't matter which way the filter faces. Yes you're right there will still be *some* radiant heat as the box is not completely sealed; however, if the box was completely sealed you would need to have some other way to get more air into the box as the stock inlets are not designed for this.

Okay the base of the filter is located about 5" from the inlets and the air is feeding into the bottom of the OEM filter box which this intake retains and where the new filter sits. It will naturally draw in more hot air when compared to what? You're not exactly giving anything to quantify that statement. Versus the OEM setup? Sure, but it's also not going to flow as much air as the OEM box. It's the same debate that happens everytime people start talking about under hood mounted filter intakes.

Any data on IAT's to prove that? I know some guys checked their IAT's on here pre/post intake installs and didn't see much of a difference, I can't remember what the variables were and what the intake was though.

I guess the phrasing "right next to" and "directly in front of" are relative... This picture proves that the air inlets are not "directly in front of" the filter and easily 3-5 inches away. My point is simply to be accurate with the description of the design and to manage peoples expectations.

The fact is that air follows the path of least resistance. So if the filter is pointing towards the engine the majority of air will automatically be drawn from that back area near the turbos first. And since its not a sealed unit, no vacuum is being created to draw air from the OEM air inlets up front. Obviously, at full speed some cool air will be forced through the front air inlets, but no matter what the air with the least resistance will come from directly in front of the filter.

Im not saying this will make a huge difference compared to other intake designs. I'm simply stating the facts and trying to keep information people read on here is as accurate as possible.

The shields are to block radiant heat from the turbo and manifold as low speed and bias air intake from the colder source at the bottom of the airbox at high speed.

Thank you for pointing out that the filter and OEM air inlets are about 5" apart, which is what I was trying to clarify.

It will naturally draw more hot air when compared to any intake with the filters facing towards and directly in front of the OEM air inlets(Injen, JT, DIY versions, etc). The Injen/JT are the best examples of the most efficient intake designs to draw cool air from the OEM air inlets.

Unfortunately the Injen is missing the heat shielding completely, and the JT's backside near the turbos is wide open so they will both still draw hot air from the engine/turbos. They probably get more cool air from the front, but their advantages wont be significant over the BMS because they all draw in some hot engine air.

If any of these intakes simply added a full barrier of heat shielding between the filters & engine it would make a huge difference. That way the hot engine air would be kept completely separate, and all the air following the path of least resistance would be forced to be drawn from the front of the car.

Any data on IAT's to prove that? I know some guys checked their IAT's on here pre/post intake installs and didn't see much of a difference, I can't remember what the variables were and what the intake was though.

I will see if I can find some or try to take some temps myself, but don’t have anything on record yet. However, I felt a huge difference with my DIY intakes. When I first added them I didn’t have any heat shielding and would quickly develop heat soak. The engine felt lethargic and the metal on the filters would be extremely hot even after a short drive.

Then I added a wall of thermal heat shielding and made a soft box barrier between the engine and filters. It made a huge difference and eliminated most, if not all of my heat soak issues. Even after multiple hard runs I still won’t get the lethargic feeling and the metal on the filters stay cool to the touch. Now there’s easily a 50 degree difference on each side of the shielding and couldn’t be more impressed.

Correct me if I'm wrong but AM is completely sealed

FYI- Nothing is written after the "quoted" message. Did you accidentally delete your text?

What is AM? Are you speaking about AEM intakes? If so, no they are not completely sealed and are similar to K&N Typhoons.

Haven't bump this in awhile, but we've got over 200 BMS Stinger intakes out now. It's a really good option and one of the few that retains the factory airbox ducting.

I have been using the BMS cold air intakes for awhile no problems on my end so far

Glad to hear!

 

[Talloneus Khan]

I am thoroughly enjoying mine. Install was easy. I highly recommend them
Its a very attractive option, especially for those thinking about buying a jb4, its a fair price, and if you bundle everything together when you buy it, saves a tiny bit of money.

Although nothing will beat the price of the diy option

So recently received my BMS intakes and installed them on Thursday. Install is straightforward, and just followed the instructions on their site. I did neglect to tape off the intake tubes while assembling, so the coating did get scratched, however, the radiator brace covers them up.

Overall impressions for me.. I like the increase in throttle response, it's pretty evident as soon as your driving around. I can tell there is a bit more response on load in the lower RPM's as well. For the power increase, can't tell really. They supposedly add some, 20 I think from dyno charts, but the butt dyno can't pick it up really.

However, they might be getting removed. Being a GT car, my DD, and a family hauler; the added sounds from turbo spool and blow off are fun to hear, but think they might get old quick. It is interesting though to hear the bleed off as your accelerating, and the slight dump of boost when letting off. But, just driving around yesterday running errands, it was a bit noticeable.

I won't return them, as I might want to see how well they perform in the cooler months and see if I can notice the power there. I will also be reaching out to a buddy of mine that is a fabricator. Maybe can add on to the intakes a bit to keep the better flow, but seal it a bit more for sound reduction.

If anything I might sell and just wait for any other intakes that will allow for better flow, but keep sounds down. Maybe look into purchasing someone else stock intakes and modifying them for conical filters and such.



TL;DR Bought intakes, like the gains, but not the sounds. Will be looking into other options.

Good, honest review. DIY, Injen, AEM, K&N all introduce these sounds as well.

Thanks... not new to any of this, last turbo car that had the filter this close to the turbo was my Supra. But then again, you want to hear those. My last two cars, CTS-V and Golf R, were quite different on the intake side. Golf R doesn't really need an intake unless upgrading the turbo from the IS38. My CTS-V whined like a pig in heat so you really couldn't hear anything except that.

Don't get me wrong though, the sounds are nice. I just would rather have it a bit more quiet on a GT car. Hopefully can find a way to use the BMS intakes and come up with something.
