Just out of curiosity, but who are you using to run cfd on your car?

The equipment draws a lot of juice and costs a fortune, the safety booth is real expensive and takes up a lot of room. Its cool to be in there during it for about 2 minutes and after that you want to GTFO, its hot, bright, loud, filled with toxic particles in the air, and otherwise terrible. I would think if a small shop had a setup to do it it would cost a small fortune.

Have you guys seen this blog before? I stumbled upon it, while looking for a stock miata's drag coefficient.
Splitter or Air Dam – Which Design is Best? | Hancha Blog Looks like a good bit of info. Attachment 185607 Attachment 185608 Attachment 185609 |
REPOST
It's technically not the same thread, but this thread was split off from the splitter height thread. |

Sweet, I hadn't seen it before. Awesome blog! Pardon the repost.

We used to use a different shop to build up chrome and then we'd grind it on our normal machines. The shop was specifically for chrome and other coatings so it ended up being cheaper than buying our own for the amount of work we did with it. No offence but i call BS on the chrome being a fortune to run. Chroming a spindle takes about 2000 watts (160ish amps at 12 volts) for about 3 minutes. Relative that's the same as running an average microwave for 5 minutes. |

I'm only speculating on the electricity, the machine here plugs into a 600 volt 4 phase plug, so it must use some serious juice. There's still a ton of overhead and up front cost.
Correct theres high up front cost however thats something the shop has to swallow. If they want business they cant skyrocket prices when the dude next door does it for much less. |

So how much does doing this help? If little, then would it be worth it if it was more aggressive with a larger opening?

https://www.miataturbo.net/attachmen...ine=1364444654 I'm always interested in what other have to say on these topics though! |
I have nothing to add v effectiveness but that small opening looks really good!!
Are there any pictures of the whole car? In saying that, the idea is to relieve air pressure created by the wheel / tyre spinning so even a small hole must help considerably........I would have thought it would releive more pressure than the louvered vents Le Mans type cars use on the top of the fenders..... But then the louvres in the fenders are placed in the correct position (If i remember my reading of the Engineer to Win etc series of books, read many years ago...) |
Ah good. I was hoping you'd reply, Pass. Is there any situation where it would be negative? For instance is it better for a track with a lot of high speed corners or a track with long straights?

This is something I'm working on and hopefully this weekend if I'm still not to sick I will get a big jump on the project.
This fender is to see what problems I'm going to encounter before chopping up 2 brand new fenders. Once I get the 2 new fenders chopped and cleaned up. Then a mould will be made from them to make either fiberglass or carbon copies of them. https://www.miataturbo.net/attachmen...ine=1364492397 The cut off portion of the fender will go straight down, then curve 90 deg back to the factory mounting position under the car. That progress will be made this weekend for sure. https://www.miataturbo.net/attachmen...ine=1364492397 |

This is something I seen on the Mclaren GT3, a multi element dive plane. I'm guessing more efficiency with the steeper angle.

I thought canards are to disrupt airflow down the side of the car (by reducing airflow entering underneath from the side) that being the case maybe the small gaps help create more/multiple disruptive vortice's than just the single trailing edge of a one piece?
Multi plane wing is for aerodynamic efficiency I wouldn't have thought an efficient down force generator there is the idea...unless it / canards do both? One other key point, my car has a front air dam that is angled up for kerbs/clearance etc. Somewhere (this thread?) I asked if you could run a splitter even if the angle was not flat....it would appear Mclaren think you can.... |
