Interested in NB. I'm considering the GT500 as well, but I like this more.

Here is a more accurate representation of what I have in mind for the NB:
Forward most point is just behind the radiator, it follows the contour in the hood, interferes with a minimal amount of the underhood structure, and lies in the lowest pressure zones of the NB hood.



I've taken a lot more of the hood bracing out than that in the past and not had any issues with hood flex.

That's exactly my thinking. The stock hood is quite good. Heck, even on my turbo car, I built everything on an oem hood because the only better option is several hundreds of dollars for full carbon to save a few pounds, and I still would've had to cut that up.

In a nut shell the idea here is:
- specifically for the miata hood's shape and airflow
- works on any factory hood
- retains hood rigidity

With those goals in mind, the result should look like it was designed for our hoods - not just a universal rectangle or something grafted on from some other manufacturer.

Well, I'm interested to see what you come up with. If it looks hot, I'm in.

Has anyone had any problems with daily driving with a vented hood? The only problem I foresee is with rain, while the car is sitting. Feasibly, I just need to relocate any electrical connections, should they lie beneath the vents.

I'm in for a nb, and would it be necessary to post up ideas of other manufacturer's louvers to pick a style that would look best to oem as if Mazda made it?

The best way to install aerocatches on an NA is to remove the front rubber hood bumpers and use those holes for the metal rods.

I've had a hood vent(GT500) on my car for the past 8 months, albeit in SoCal, without issues. If the car is sitting when it's raining outside, the car cover itself generally keeps enough water out. If I wash the car I usually throw some saran wrap over it with some blue tape to keep water from just pouring it.

I'm getting ready to just cut holes in my hood and put mesh in the holes.

If you can make these happen before next spring, and for less than $150, I am a guaranteed buy. I would actually give you my money now to pre-order if that would help.

As far as hood scoops in weather go, I ran one for years when I daily drove my red NA and never had any issues. Sean is more cautious than I am, I washed the car, left it parked in the rain, etc. and never covered the vents or anything.
The important part is not having the opening above the valve cover, some vented hoods have holes right above it which is no good. Of course, I have this in mind and the vent placement doesn't look like it will be directly above anything that it shouldn't be.

Re: mesh vs. louvers, I've run mesh and switched to louvers or just a big opening for many vents because the mesh blocks a significant amount of flow. Also, louvers serve the second purpose of creating lower pressure just behind each 'blade' which aids in extracting the air, which mesh and other styles don't do.

Thanks for your interest guys, I'm very encouraged! We aren't going to collect any money yet. Working on becoming a vendor right now, and once I've got at least preliminary proofs in hand we'll start a group buy where there will be a partial deposit to get the ball rolling.

Not to derail the thread too much but you mentioned you also had other products in the pipeline. What are they if you don't mind me asking?

I am in the middle of heavily modifying a lot of aspects of my car and if there are new products coming relatively soon I would be interested to know now so I can judge if I should wait.

Ryan - As excited as I am about what we're working on, I can't get ahead of myself. We aren't very far off from the first couple things becoming available though, so you shouldn't have to wait very long.

One of the primary rules I've set for myself is to focus on only a couple things at most at one time instead of getting spread out too thin on too many things in development. I want to focus on getting a part just how I want it, then I can move on to the next one. We have a couple things very close to finished and several more on the drawing board, but they'll be announced/released only once I'm totally satisfied with each one.

Hi, id like to see the product and maybe intersted in South Africa. However ive been contemplating the Nissan GTR35 vents which is a NACA duct tried and tested. Thats about as nice a duct as you gonna get and probably as effective as well? food for thought? just my their expensive as hell though

A not so serious suggestion:
Make the vents out of the hood itself (only the "prop" part needs fabricating, the template can be printed)?

Not serious since the hood Alu is thin; cutting it with control is not easy, it will break in the twisted parts (over time at least).

But if it would have been easy to do it would have been elegant, not even needing paint
