Ever wonder what the flow around the Mazda RX7 looks like? How about the Toyota Supra? Toyota MR2? or the new Scion FRS?

I've done some tests and compiled everything in an easy-to-follow video located below. Enjoy!

 

Interesting video, You dont come by things that compare newer and older very often which is a shame really. I wonder is the S5 turbo lip, sides and spoiler had much of an effect over/under the aero package mentioned in the video.

 

very cool!

 

We need more testing like this!

How about one with the RE-A FC2000 Aero?

 

Very cool, Subscribed

some things that I'd be interested in future videos:

single element vs dual element wings
gurney flaps
fender vents
hood vents
side skirts that just go down vs. ones that come out further.

I know some of this might be hard to do with smaller models especially stuff that relies on engine bay flow characteristics.


Also, you never mention what air speeds those water velocities map to, any idea?

 

I always knew the vert had really bad aerodynamics in the rear, the trunk lid is like an anti-spoiler. The front does fair better though

I did some research a few years ago on the aerodynamic drag of an FC and a Lambo, and the FC won out because shear down force wasn't a consideration.

 

A lot of this raced through my mind as well. Very cool that you did this, and I have subscribed to the channel. Thanks!

 

Hey guys,

thank you for the positive feedback. I'm doing this research in my free-time (outside of my regular work) so I'll try my best and accommodate everyone's requests.

Eage8, I already have a video on gurney flaps. I apologize that it's not of the same quality, I made it 2-3 years ago, but it should answer some questions you have.

 

I actually did a very basic computational fluid dynamics project on my FC. it was pretty damn interesting i will be honest. I only used a 2-D model which did not take into account the body contours or gaps in the hood/bumper/mirrors. I will post some of the data i found. I was able to come very close to matching the cars actual Cd in air in a much smaller tunnel using water flow. This is great stuff and I am looking forward to seeing more!

 

Totally cool video.

It would be really neat to try out the body kits, diffusers, and wings we're using today.

I'd really like to see how the BN kit affects the FC front end and how well the rear under diffuser does.

 

I want to see the vert top down vs top up!

 

This and is adding the small OEM Duck spoiler useful or not.

Very nice work.

 

I read an article about how amazing that wind deflector is in the vert rx7

 

It makes a huge difference actually, and does a very good job of keeping you from freezing your *** off in cooler temperatures. The only thing I do not like about it is having to move the seats to flip it up. I always have an incredibly hard time getting the driver seat back in its sweet spot for some reason.

 

Very interesting. You also have impeccable taste since you stated the FC is one of your favorites . I recall reading some factory documents from Mercedes for the 190e where the "duck-bill" spoiler reduced the rear lift by half... interesting that the spoiler as part of the FC essentially did the same thing.

Great video!
