I have a 1992 stock 1.6. I am more interested in reducing drag. I think Flyin' Miata should consider a flat-bottom kit, especially with their in-house production capabilities.
Great video. Having done some research and seen some cfd data on several car body shapes, im surprised that hardly anyone is reducing drag by adding some large flat pieces of plastic(about maybe 1-2 feet long, 1-2 feet tall) behind the rear wheels extending from the inner fender well towards the rear of the car and curving them inwards about 2 degrees. It "should" be good to reduce Cd by about .01 and assist in smoothing out the turbulence behind the car. Plus, it can look good too if done well. lol.
Someone neds to make a lightweight carbon fibre fastback hardtop, the miata's steep rear glass slope causes way too much turbulence behind the car and so the rear wing needs to be really high to be effective.
Wind tunnels are not as accessible as CFD simulations, unfortunately, so you may have to settle for cool pressure maps and flow diagrams as seen on the 9Lives Racing site. You can see some pretty interesting effects with a long (6' or so) string attached to an air hose, it will show you how the air moves over various features of the car.
Have some fun with some styrofoam and a billion pieces of string taped to the car. Using a box fan or air compressor you can learn a lot. If you find a styrofoam shape that works well, try your hand at glassing it. Maybe after you spend enough time playing around, you’ll understand why very few people actually get around to wind tunnel testing things properly or doing much in the way of aerodynamic engineering
I have a global mx-5 cup car that I'm looking at slapping an nine-lives rear wing on as it's currently unstable in high speed corners. Do you think I need a front splitter to compensate as well? I should note the average speed is 80mph on a local track
Yay more Flyin' Miata stuff. You guys are great keep it up
I don't even care the topic, I could listen to Keith Tanner talk forever.
As you can see this is a bone-stock Miata behind me...
Really didn't know your frame rails have threads for an underside plate! I'm gonna have to grab one just for that reason.

LRB Speed has a full flat front undertray made out of aluminum. Noticeable difference on my NA at highway speeds compared to stock plastic one

Would love to see lip spoilers, small wings, and big wings all in a wind tunnel with smoke showing the pathway it takes.

Rear diffusers!!! And how much of a ballon is the rear bumper for the na/nb.

What about a fast back?
