Front Splitters: Do They Work?
Hi everyone,
My name is Mike and I'm from NYC. I hope this is the right place to post but I was wondering if anyone had any experience with front splitters. I'm really not sure if they do anything and if they're only for performance cars. I read that they can save you on MPG by reducing drag. Any thoughts? Is it worth it to put on a 10 year old Camry? |
I have one on my recently-retired Civic Wagon. While I didn't do any accurate testing, it did seem to help on the highway. My theory was that it was directing air around the smoother sides of the car instead allowing it to cause drag on the rough undercarriage. I was careful not to make it too big, that would increase downforce and drag. Mine stuck out just slightly more than the bumper. Make a cardboard prototype and see if it works on your Camry! A vertical air dam is another approach.

Thanks for that! It's that your Civic? What did you use for the splitter and side skirts?

splitter
The old-school research recommended the airdam.
Splitters were for the track only,and by default,induced drag,due to the downforce. The reverse canting on my pickups nose produces measurable downforce even without a splitter. |

Gasoline Fumes — Thanks for reposting that. Times past I've wasted whole minutes in Google's search function trying to find an example.
I think it's a good [possibly extreme] example of a central jet. There seems to be advantage to having most of the air under the car being sucked into the center. (Away from the wheels/tires?) The way I see to improve it would be to have the deflectors twice as tall, up to the parking light, and vented to provide an air curtain over the front wheels. As to the question at hand, they do work. They control the stagnation point if they are even with the body, and add downforce if they protrude ahead of the body. |

Here is my best attempt at an air dam. At least, the last picture I saved before something corrupted the file, which I never recreated.
https://ecomodder.com/forum/member-f...23-9-48-49.png The air dam is concaved to feed air sideways to the barge boards, which admittedly might should be bigger. Based on observing OEM solutions, the outlet should be ±1 inch across the middle third of the wheel and the inlet can be any shape with a larger area to create a converging duct. |

Splitter, barge boards (whatever). OP, it must be fun. That little Civic hits the mark. Good luck . . |
