Need Aero Recommendations

[botsapper]

Here's a Photoshop concept (Probe-like)to start ideas. Your fastback (almost bought one) is the most attractive of all the types. There are hundreds of kits for the 240/140/Silvia model. I hacked a full widebody kit to create an aero one. I used it to cover the tire track widths on the front & rear from sticking out of the body contours. The front wells are open but have gentle front-edge fences. I love the look of lightweight forged wheels so I created lightweight lexan covers. I know the problems from brake dust, so use brake dust covers. The rear wheel wells are completely covered. Wiper fence, low-profile side mirrors and flat HID light conversions. I still kept a small open (adjustable apertures) grill opening for some intake & cooling use. Rear wing deletion but added tail length all the way to the rear bumper line. Full belly pan & rear diffuser to finish.

nice picture!


did you make? (can you do mine?)

Awesome! That's the idea I have for a Miata, except with an aircraft-style cockpit on the driver's side and the passenger side covered by bodywork.

To make clear this was a Photoshop concept to help start & stimulate aero concepts for 240SX aero mods. In another thread there was a Z racing car that went through wind tunnel tests. They tested & got good numbers on some body modifications; semi-blocked front valance, side skirts & wheel arches. There are existing 240SX bodykits that could accomplish some of this for eco-modders. This PS study modified an existing kit & extended eco-modder ideas & concepts to create it.

Wow. I want one.

botsapper: Thanks for clearing that up. I should have my car scanned and modelled by the end of next week. I will be taking your concept and applying some of this to my scanned model for CFD testing inside ANSYS with various alterations. Some formula 1 teams do this to save expenses on wind tunnel testing and parts fabrication. Would there be any way you could illustrate how you would modify the rear with another photoshop image? Great Work ! BTW

Botsapper - Love the illustration that you did on this. I missed this thread entirely when it was posted and just found it.
You have some true skills with PhotoShop.

What ever happened to this project ?

unfortunately I came to the realization that the car would never meet my fuel efficiency goal with the drive train it came equipped with. When I bought the car I was wanting a project car that was sporty, RWD and simple to work on that handled well yet still somewhat economical. With mid to high 20's for mpg and only a 275 mile range on a tank of fuel and my tastes shifting from performance to efficiency I decided to sell it. I did however get a 3d Laserscan of the car before I sold so that if I ever got another, I would already have some data to work with. I thought about attempting a TDI motor swap from a VW but I could not dedicate enough time and resources to get the project off the ground. So I did the next best thing and got a 98 VW Jetta TDI and have started working on it with a goal of 70mpg on biodiesel. I plan on getting it laserscanned as well and pick up where I left off with my 240 on the aero stuff. Obviously the jetta presents more challenges but it is the most efficient non hybrid/EV that I could afford.
