Really enjoy all the data collecting/testing you guys do! Telling us you feel a difference vs showing us it makes a difference is hugely appreciated. Thanks for the work.
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 - 194°, Headlights Up - 194° Run 2: Headlights Down - 194°, Headlights Up - 198° Run 3: Headlights Down - 196°, Headlights Up - 194°
Interesting data, I've had a set of these sitting in my garage for the last couple of years that I've never gotten around to installing. I don't figure it'll make a huge difference on my car since its still a 1.6L.
There’s probably ways to increase the functionality like running a duct from the TSI to the intake, but most people don’t, so that wouldn’t have been real for this test.
Cool data! Kinda what I thought they do something, but not a much. Would love to see LRB vs Singular vs r theory vs..... hood vents. Most manufacturers do the wool test but can’t find any data a vs b vs c..... Might be hard to find people with all the different varieties tho. (I like the looks of LRB or R theory).
I know this was posted back in 2020, but if you're interested in trying another idea Simpson Designs makes a hood with vents at the back near the hinges. I was talking with the guy who makes them and he was saying that someone did some testing and found that the vented hood with turn signal intakes made for upwards of 40 degree cooler engine bay temps (probably tested around 60-70 degrees F) I've got the hood as I needed more clearance for my engine swap
very interesting i've read on forums they don't have that much of an effect, and this proved it. but im buying a set of jass performance sti's just for the looks lol
As I understand it the area around the turn signal on an NA is a low pressure area, which means it takes more power to draw in air from there. So it's a trade off I'd say. Lower intake temp but the engine works harder to suck air in. In my Miata racing experience I don't see people using turn signal intakes, but we have lots of other options to reroute cool air into the intake from high pressure areas that involve cutting sheet metal and so are maybe not appealing for a street car.
Thanks for the input! On the setup we took these off of we have cold air ducting right into the intake, so sucking in cold air is less of an issue on the other car.
Is there any way you could relocate the sensor so it isn't sitting right behind the radiator? It must be getting pretty heat soaked where it is right now.
Sitting here in europe and having no clue how hot or cold it is. I love your content but could you do the math for us lazy non americano youtubers and put some °Celsius numbers in there next time?
I will keep that in mind haha. Just know that my car runs really hot with the current setup lol. If it’s 85* F outside (29.5* C), my car would be at like 110* F (43.3* C) at the intake. It’s much better now that I’ve made some more changes.
@@NappMotorsports understood I’m very much into the classy mods also. Love the looks of both of your cars. First thing I did when I got my Miata was undo a lot of the “stance” mods.
Stefan, are you still running factory plastic undertray? I wonder If sealing the radiator would further improve NACA duct efficiency? I also wonder if singular hood vents would also help with expelling heat out of engine bay to improve IATs? Who's gonna lend some more parts For SCIENCE!
I’d be down to try hood vents, but not on my car haha. We’d have to use a car that doesn’t need a modified hood to clear anything (Cough, Dylan, cough). I also haven’t modified my undertray. I’ll do that as another test.
Not enough room behind the turn signal. The pop up headlight actually sit directly behind the intakes. So they let in cool air but it can’t be directed anywhere unless you deleted your headlights. I’m sure some race cars have done it.
@@NappMotorsports that's why I got a spare bonnet. As the vents are negative air they pull. As the mouth of the car is positive, it pushes, combined you have a circular system which both pushes air through the radiator etc. But that also sucks it out of the top. Loved the video though. Thanks.
That pan is pretty important on Miatas. I’d get the oem one modified or modify a lrb 3pc one. Will be a cheap date and I’d be willing to bet you see differences on cooling temps and potentially iat as well.

Damn that's crazy, I wanted the intake turn signal but after this, I'm good with stock. Keep up the great videos guys !
Thanks!!

I might need to gather a few hoods before we try this out.
love the real deal data stuff. Well done guys.
Thanks!
Great info man. Earned a sub. I've never ran Pineview before, but let me know if you plan to hit NYST. Love to run with you one day.
Thanks! I’d love to go to NYST. It’s been on my list for years.
Loving your guys videos so far! Very nice quality for such a small channel!!!
Thanks! We really appreciate it, and we’re looking forward to keeping it up!
Napp Motorsports amazing! Maybe we can collaborate sometime! Where are you based out of???
Rochester, NY. You?

I’d love to put a Simpson hood on the K swap but I need to get my hands on one first.
Thanks for bringing us yet another vibe 🥂 enjoyed
Glad you like it!

Function or form, at the end of the day, it’s all about what you like.

Great data, more please!
Thanks! Working on more!
Great video! Sub'd!
Thanks!!
Great video,where do you buy your headlight intake from and what is the make off it.
The headlight intake is from Carbon Miata and it’s Carbon Fiber.
Have you considered testing AIT's on the Jackson Racing CAI system for NA cars?
I’ve only seen one of these kits in person. I’m not the biggest fan of the construction if you’re talking about the ram air setup.
@@NappMotorsports yeah that's the one. I have one on my car. It is cheaply built.
Is there any way you could relocate the sensor so it isn't sitting right behind the radiator? It must be getting pretty heat soaked where it is right now.
I did move it to the end of the filter itself on Friday, and it dropped measured intake temps around 10*, so that was a nice free 5 minute fix.
Think these needed hood vents or hood spacers, the TSI is cramming air in with no way to get out smoothly.
Hood vents are definitely a huge help.

Does any one make some clean looking hood vents for the NAs? That would probably work wonders
There's a couple, like spiked performance, but I don't want to put hood vents on my street car. I'm trying to maintain an OEM + look from the outside.

Why don't you connect the intakes directly to the air intake making it a sealed system like a ram air intake!?
Not enough room behind the turn signal. The pop up headlight actually sit directly behind the intakes. So they let in cool air but it can’t be directed anywhere unless you deleted your headlights. I’m sure some race cars have done it.
@@NappMotorsports, then put a scoop on it. Where there's a will there's a way.
We've done that also via a naca duct. th-cam.com/video/TDbcGCA2rSc/w-d-xo.html
@@NappMotorsports, that is not a hood scoop and it is not sealed.
None of this will translate to any horsepower gain so what are your goals here? (besides 5-10 deg drop in temp)
But... There's no where for that air to go.
Vent the bonnet and it'll pull TONS more air.
I don’t plan on cutting my hood open. Maybe on a racecar.

Do you have a belly pan on the car?
I don’t on the K Swap. It doesn’t fit without some modification, and I just haven’t gotten to it yet.
That pan is pretty important on Miatas. I’d get the oem one modified or modify a lrb 3pc one. Will be a cheap date and I’d be willing to bet you see differences on cooling temps and potentially iat as well.
Tyler I second this. Those are essential to radiator airflow in these cars.
