Just don’t ever assume locking your doors does anything they snap out easily and you can reach the inside door lock with your arm through the hole. The NACA style ones simply flow a lot more air into the cockpit and you should have eye protection if you have them.
I've been running mine for 2 years on the street/track now and have not had any debris come in through mine. I dunno, I think you guys are over analyzing this. Debris could come in through an open window or over the windshield too but it generally doesn't. Mine from advanced autosports: https://www.miataturbo.net/attachmen...ine=1339251316 |

I wish someone made a driver side quarter window with a wee little NACA duct on it like the bottom right one in the above picture so that there was enough room between it and the steering wheel to put a 90 degree bend on it pointing into the footwell for some ventilation down there.

Anyone have a link to the round snap in ones?
I don't know if it's manopause or what but I get so hot while driving my car, these mx5's just seem to have NO airflow even with the windows open and the (non ac) fan on..... As mine gets DD use the smaller ones with the cotter pin trick look perfect. |

I'm glad I found this thread as I was looking for cooling solutions for after I rip out my AC.
The Advance Autosports NACA units appear to be slightly smaller than the Weekend Racer version. Advance: https://www.miataturbo.net/attachmen...ine=1339436217 http://www.advanced-autosports.com/i...roducts_id=126 Weekend: https://www.miataturbo.net/attachmen...ine=1339436217 http://www.weekend-racer.com/index.p...roducts_id=313 The Weekend one looks like its too big jammed in there at an angle. It looks like Curly, Wildo and Njn63 are all running the Advance version, and to my eye, its more aesthetically pleasing as its tucked down further into the available space. I'm sure they are both highly effective. The ability to close the round ones is also attractive... How well do the round pop-out ones keep out the rain? |

Word of advice, if you do these on your own, practice drilling on a scrap piece first, like the piece you cut out for the duct. Do your drilling wrong and the swarf will scrape the Lexan as it spins around the bit. Passenger side: https://www.miataturbo.net/attachmen...ine=1339448566 https://www.miataturbo.net/attachmen...ine=1339448566 Driver's side, with no issues with hand/duct interference. And there's no way you're fitting your arm in there. A keen eye will notice I wasn't very accurate when measuring between sides. https://www.miataturbo.net/attachmen...ine=1339448566 https://www.miataturbo.net/attachmen...ine=1339448566 https://www.miataturbo.net/attachmen...ine=1339448566 |

Better pictures of my one from advanced. I only ordered the passenger side one because I was worried it'd interfere with the area around the steering wheel. I think there would be enough room but I kind of want a lower profile one like Curly has on the driver's side.

It has stayed on at over 100 mph and keeps most water out: https://www.miataturbo.net/attachmen...ine=1339455168 |

Thanks for the comparison. I am going to put a set of these NACA vent ducts in my track car. As far as the track debris, I could see that happening LOL. Freaking rubber bits flying everywhere sometimes. A piece of coarse wire mesh over the exit end of the duct would help with that.
Keep in mind for those reading this thread whether or not your racing and/or HPDE organization allows you to have the windows up. NASA, where I race, requires the front windows to be completely rolled down. Mine is actually removed from the car completely. So a venting solution that uses the rollup window will not work in my case. But the NACA vent windows will. Also, all you paint cap guys might try a different method. A rubber ball works perfectly and seals perfectly. No tape needed. It has worked extremely well for us in the past. |
I've tried. I'd use one if I had the duct pictured above, but if you notice I have four rivets in mine. The ball barely goes in before it hits them, and just falls out. And with the rectangular opening, there's no putting the balls in from the outside.

Here's a stupid question, how hard are these to install? Mainly do I need a new window seal, or is there a way to get the old one off without destroying it?
|
My seal came off perfectly fine. The biggest pain in the nutsack was the black goop on the doors. Use lube of personal preference for installing the new seal and you'll be golden.
