Aero wheels

Would you share your model? I’m curious if I could just the center piece in a 3D printer.

The center piece is 3d printable.

Random example, my phone goes faster from 20% to 5% than from 80% to 65%. At least, seemingly.

Did anyone every explore a disc of sorts for the inside of the wheel?

I have to say, looking under the bottom of the car on a transport the other day, I bet there is another 2% of efficiency to be gained by covering all the little gaps on the bottom of the car, which is already very smooth and impressive, but perhaps there is still room for smoothing on the bottom, near the suspension arms...

Can you share on thingiverse or I can dm my email. Whay is the clear disk made of?

 

[Evogreen]

I paid a lot of money to get it modelled, so not willing to share it. The Clear disk is poly-carbonate.

Racing tape ... ie speed tape will do wonders for aero efficiency and range

I just got some numbers in for putting my covers on the 19" slipstream wheel. I saw 4% improvement at 110km/h. I can give more details if anyone is interested. I used the same bracket that fits the 21" turbine wheels.

I just saw a Model 3 at the SuperCharger and the Aero wheels look pretty good in person. The owner said that they look really good with the Aero covers off too.

Tested some simple disk wheel covers. They're not too pretty but reduce energy consumption about a 6.5% at 60 mph. I was cautious not to use the brakes and over heat the rotors as they have no vents at all. I will need to do some more extensive testing speed vs energy consumption and possibly measure rotor temperatures with & without covers after a stop.

For brake cooling, you could use these very low drag scoops. I used them on my airplane and they really work. You might only need 2-4 and they could be very small but still bring in significant air. NACA duct - Wikipedia

They would only need to be about an inch wide and 2 in long. pointing in the direction of rotation.
