We use the same louvers with a different chassis-specific template for the RX-8:

For an alternative to our standard NA/NB louvers, some have fitted the NC louvers in their NBs. Here's Johnny C's V8 car with the louvers in bare aluminum:

We partnered with Danny George to help his 700-something horsepower beast stay cool. Same NC louvers:

Another good shot came in of Danny at Road Atlanta this past weekend for Global Time Attack. Is the car on the ridiculous side of things? Yep. But Danny is all about just living it up, chasing dreams, and never taking things too seriously, and we fully support that.

Plus, his V8 needed all the help it could get to stay cool and that's why he came to us :)

Report just came in from Danny George Racing:

that nb looks nuts. I must read the build thread. is there one?

Thats danny george, miata dorifto king.

Just looked him up. Yeah, dor!fto. Nvm I don't wanna know

Looks like the car doubles as a GTA car though. Or its a second car.

Danny previously competed in Formula Drift - his operation is far from the 'zip-tied together, can't scrape up enough change to buy tires, thinks primer is a paint color' amateur drift stereotype ;)

Car was just converted over for time attack, using the same big V8 as they had for FD but with a completely new/undeveloped suspension and aero package in time for Road Atlanta, and they placed 3rd. I see good things in their future in time attack.

...and just like that I'm interested again :D

Sorry for off topic, and free bumps for your awesome product

The NC louvres look better on the NB than the NA/NB louvres IMO, they preserve the "hump" and look to curve around it naturally.

Can you please post a picture of the underside of an NA/NB bonnet/hood with these installed, I'd like to see how much underside bracing needs to be cut?

I assume it will be very similar to FrankB's NB with the NA/NB louvre cuts but could be moved a tad forward:

Ryan, have you done testing with the NC louvers on an NB?

I have a set of NB's yet to be installed but those NC look really good!

We haven't done any specific testing with the NC louvers in the NB, but placement is very good and we've applied all the same features in fin design, gurney flap, etc. so I expect very good performance.

I'll ping Johnny C to see if he can provide an under-side pic.

Have you considered some kind of cover/plug for street/track cars (outside of your desert down there) I've been trying to come up with a good way to do it and I can't come up with anything except a whole replacement louver that doesn't have actual holes.

Well the NA/NB louvers on that chassis and the NC louvers on the NC (I can't speak for the NC louvers on an NB) were designed/placed to not drip water onto anything in the engine bay that would be upset about it.

However, it is on the drawing board to take a look at options on that subject as we have a project coming up on a 2012 Camaro with a specific request for some type of rain blocker. Nothing on that subject yet though.

-Ryan

With the amount of rain we get up here its not just drips but it goes everywhere. Stuff like my turbo and EBC solenoid are under there. Its on my drawing board too and this is the closest thing I've found that I would consider acceptable.

How-To: Build Your Own RS Style Hood Vents

2nd post.

Most turbos I've seen on BPs sit further back than any of our hood louvers.

Hmmm, I'll look again.

My ARTech EFR setup puts the turbo right under the louver. This is of course while I have a spare hood. Attachment 184089

FrankB - I would move that air filter. That really goes for whether or not there was a hood vent right above it. The air is hot there.

What's your intake look like. I had trouble fitting mine anywhere else, I need some tighter radius tubing.

Yeah, I know I've just been too lazy to make a new intake setup. I'll get around to it before my next track weekend though.

Update on the NC louvers in the NB:
- They do intersect with the main "A" bracing that runs from the rear corners to the front latch area, but they don't interfere with any of the perimeter bracing.
- Their curve matches the curve of the NB hood bulge very nicely.
- Hood prop and hood latch remain funtional.

This is what I'm afraid of, I have the same setup, but I have zero place to put the intake filter because the flip up headlights and A/C compressor are in the way.

Saw this on my instagram

Your vents are everywhere!

edit: wtf, auto-embedded instagram posts

Yessir, Jager Racing commissioned us to do a custom set for their wasp carbon hood based off their pressure data gathered from that car. Those will be available to the STi market July-ish.

:)

Just a small suggestion. On the template, put a thin black line delineating the extra you need to cut the openings if you want to use the edge trim. Guesstimating a 1/16" all the way around is a good way to make the lines uneven, IMHO.

Other than that small quibble, I am pretty impressed by the parts themselves.

Please make an NC vent template for NB hood.

Thanks for the feedback! I'll look into something designating the small difference.

If someone bought an NC hood louver kit and requested a template for an NB, I have no problem making that happen ;)

-Ryan

my hood vents worked excellent in 95* air temperatures. motor got a little hot to 190 (normally it sits at 170). I never had to let it cool.

I also got conformation that the hood vents work. as my power steering overheated, and spit fluid all over my windshield and wing. lol.

Any way to see the NC vents on an NA? :3

Your car is looking great out there!

As far as we know this has not been done yet. However, we expect the louvers would be too wide if placed correctly and interfere with the pop up headlights. The NB does not have this issue.

thank you sir! it has a lot of blood sweat and tears in it. mostly blood and sweat....

Minus the center vent. About to install the Keisler spindles with proto ducts! They looked great btw

The only thing I wish is that the finish wasn't so "spotty" looking. I may cover everything up under the hood and on top and hit them with a coat of fresh black one day, certainly not a big deal.

Looks great!

Yes, the black anodize doesn't have the nice smooth gloss look of a nice paint or powdercoat, but any paint will adhere right to it with no problems so it can be painted however you like, and it's much easier to paint with the black undercoat rather than bare aluminum.

Yea, it does have a nice textured feel so I may try to rattlecan them. Feel free to use the photos on your website if you wish, or I can send some better ones your way soon. I know a bunch of people (myself included) were wondering how the NC pieces look on the NB, and those stickered up racecars are a bit hard to judge by.

I really like the look of the NC vents on the NB hood. Can I buy them somewhere in Europe? I think someone in the UK used to sell your products - with a nice template for the NB of course... ;-) ?

Racing Beat Europe is our dealer on your side of the pond and they have the NC kits in stock :likecat:

MX5 BONNET LOUVERS NC model by SINGULAR MOTORSPORTS

Reports from those who have put these in their NB hoods are that they use the NC template as-is out of the kit and it works perfectly.

I just had my guy line up where the "hump" was like we talked about and it was fine. He originally read the directions in the box and send me a shot at 12.5" from front, but it was too far back.

Good point on that distinction - the template itself works as-is, no need to modify it. However, the measurement written on it for how far back to space it from the front of the hood is indeed for an NC hood, so that should be disregarded for the NB. Just place so it aligns around the hump.

I have a feeling more people will be ordering the NC louvres now ;)

James T sent us this fantastic time lapse installation video of the NA/NB hood louvers.

An error occurred. No video.

Fixed that, thanks for the heads up!

Great video... Sorry to see that chipped edge at left intake though. Even with this throughout taping of the hood.

That template stick surprisingly well. I pealed a bit of clear off with mine. A blow dryer goes a long way when pealing the vinyl off the hood.
