Miata Headlight Intake - Form or Function? (NACA Duct)
ฝัง

- This is the first episode in a new series of "How To" style videos that we will be posting on Wednesdays. We are going to be installing and testing out a NACA Duct Headlight Cover from Carbon Miata. Will this headlight intake drop my intake air temperatures, or is this just another all form, no function mod?

Interested in more data? We did a TSI Test like you guys asked for! Check it out here: th-cam.com/video/Gi-049QG154/w-d-xo.html
Most amazing thing about this is that the carbon Miata part fit
😂😂😂
There were some questions about how my coolant temp changed with the intakes, so I'll sticky this at the top. You can also see them on the KTuner log window as "ECT" (Engine Coolant Temperature) to the lower left of the IAT reading.
Intake Air Temp vs. Coolant Temp
Run 1: Headlights Down - 189°, Headlights Up - 187°
Run 2: Headlights Down - 187°, Headlights Up - 187°
I think it was hotter because on the first run your engine was a lot colder. As you said in the video, you touched the radiator and it was still hot, so I think that is what impacted the temperature.
Engine/coolant temps were the same run to run, I made sure of it.
Bending out a heat shield to cover the filter and gold taping it would help a lot, though without a metal brake its going to be job to build. However that would probably be the best thing to lower the iats.
I agree. There just isn’t a whole lot of space. Also with the turbo next year and the intake on the other side, I’m not sure it’s worth the effort.
Cool. Been planning to install a cold air filter with it ending up in exactly the same place as yours and am buying a couple of these (I prefer it remaining symetrical) and this tells me it will work, thanks!
K swap or BP? Either way, these are great. I wish I had a use for one with the turbo setup but there’s really no need.
@@NappMotorsports Just the vented covers. i was planning to put in a cold air intake, into exactly the same position as yours, right behind where the vent will be, exactly the same. So this tells me it should work quite well. Thanks!
I'm in the UK, so will just have to cut a gap through that black plastic, like you mentioned. I haven't looked yet, but I'm presuming there is one on mine.
Enjoyed the how-to style of this one, Stefan! Keep up the great work.
If you have any interest in driving/reviewing the Mini let me know!
Thanks! I’ll slide into your DM’s once we clear up some schedule.
I like this style of content
Awesome! We’ll keep making it then. Thanks!
You could get the headlight cover wrapped white, maybe cut a bit out of the wrap to highlight the duct and CF.
Not a bad idea if I can get a good match. I don’t mind the mismatch though. I thought I would.
Really enjoyed the content layout with more technical info. Had a great balance of talk vs detail shots! Keep it up!
Glad you liked it! Thanks!
Should get some Turn signal intakes aswell! Much love from Australia
I will actually be recording one of these with turn signal intakes today! I happen to have a set in the garage. Video should be up next Wednesday for that.
IAT Video is up!
The iat May be higher now with them up since the air that was getting rammed under and around the light is escaping from the new vent. Just an idea and a bit of a double edged sword if it’s the case. At least it did actually improve the headlight down temps. That’s how I drive most the time as well and have been thinking about getting this since the stock engine and rad doesn’t run very cool to begin with. Stoked to see the progress on this. I’ve always wanted to k swap my Miata but I’ve never had the money or dedication to save up haha
Yeah I definitely think it has to do with the airflow around the NACA duct, but headlights down is what matters.
Afraid that won't do much at all - the inner surfaces of the intake need to be sharper, and the walls must be at a 90* angle. Rounded edges like that allow the airflow to separate, further reducing the duct's efficiency (about 50% of a conventional inlet), and allowing uneven flow in crosswinds. Headlight intakes seem to be a good idea, but outside of custom jobs they don't seem to be done too well.
I mean if you watch the video, it did help with IAT’s.
9:53 man i thought this was gonna be where the video ends and there is a plot twist :D
(because of the truck and the sign on the bridge)
*Insert Final Destination scene*
I think it’d be kinda interesting to try a Randall cowl intake for this setup. Might be cramped and awkward but I’d think it’d help with bringing the IATs down.
I’ll see if I can get my hand on one. Might be able to make one or print one.
Napp Motorsports Definitely make it or print it if you can, the only way I’ve seen to get it premade is in carbon fiber and like some stupid high price because of it.
@@redey1290 now it's a stupid high price? I though good parts cost good money? It's true too that the American dollar isn't worth spit.
Great video man thanks
Thanks! Glad you liked it.
Great vid! Curious if you’re familiar with the “Zoom Headlight intake” it looks better IMO and has a bigger air inlet. It would be interesting to see a comparison and if there’s any temp improvements with a full width inlet dumping even more fresh air over the air intake.
I’ve seen them, but never in person. I’d be willing to try it if I can get my hands on one.
Have you (or anyone you know) ever tried a louvered hood in addition to the intake?
I have not. Idk anyone who has done the test.
Interesting, thanks for adding some data! Is the carbon Miata lid an actual “NACA” duct? It’s not specified on the website, and there are other vendors that do. Wondering if that could make a difference in flow.
It doesn’t have the sharp edges that are typically seen in a NACA duct, so it possibly could be less effective.
Great tech.
Thanks!
Did you mention a weight difference or did I miss it?
I didn’t. I might do this though, even though it involves taking it off haha. I’m curious.
Why are you worried about rain water getting in? What could is mess up?
In my intake? Water doesn’t like to compress, so getting it in your engine can cause serious damage.
I'm gonna do that, I rather have a good cooling intake than a hot one.
Yessir! And I think it looks pretty sweet.
where did you order that intake elbow? I'm trying to finish my K24Z3 Miata.
Siliconeintakes.com
Can’t recommend them enough. Everything is like 2 day shipping and super high quality.
Isn't the intake air hot because of the style of intake? Maby you should get a cold air intake instead.
It wasn't the ideal setup. Now that the car is turbo the intake is different. If it was going to stay NA long term we would have modified it a bit more.
@@NappMotorsports ok. I didn't know you turbocharged it later. That makes a lot more sence now.
I just bought my second one so I now have carbon fiber vented for both lights. God Almighty are they expensive, $290 for both. I guess prestige says something.
Good parts cost good money!
@@NappMotorsports I looked it up, the process is suppose to be highly specialized, I have watched it being done and there a few things involved.
Does it climb on ya while sitting at light?
Typically yes as there isn’t a flow of fresh air.
@@NappMotorsports The fan doesn't seem to help much but I guess it could be worse. I never recall seeing the heating problems on a V8
could intake turn signals maybe help ?
I think they would, I’m just not the biggest fan of them so I don’t want to run them. I could steal Dylan’s set real quick and try it out.
Turn signal intake video is up on our channel!
Napp Motorsports awesome I watched it already great video , I was hoping for better results tbh .
Definitely worth imo, looks better. Kinda a why not mod you know?
👍🏽
