Just Some Aero Questions

[Mad Hatter]

All kinds of wings out and about, I would avoid those ebay specials! But very happy with my Aluminum 9 lives wing. they are very race oriented, its not a ricer special.

 

[Mad Hatter]

This is the same as my wing. If you mount it the way they have it in this picture, the first lap over 120 mph will mean a twisted trunk lid.



We put a large metal pad to distribute the load. So far it holds up fine with speeds up-to 140mph.

 

[Mad Hatter]

And how long did I nag you to do it?

But you should also say that you run in an unrestricted aero class. So of course you should run one and as much aero as your wallet can essentially handle and clears the public roads there.

bob isn’t wrong for running no aero in a restricted class.

Just gotta make it right for whatever you’re doing with the car, driver preferences, and ability to tune the car suspension wise.

Understood, I would not get a wing for 4 to 5 track days a year either. And it took years of your nagging before I finally listened to you and got my self a wang.

Lol. Not sure is it was years...but that could mean just 2. It was probably however long you ran the splitter without the wing.

Along these lines, years ago I was reading about an F1 designer that said aero should be an "open" area on F1 cars. his theory was that aero was actually the only thing that was actually free, so why not use it. Problem is, you still need HP to drag that barn door down the long straights, but I guess you could also pair it down to nothing if you didn't have the power. I think the fast guys would still be fast, but it was an interesting point of view.
If you've ever seen a sprint car go around a corner on the inside wheels... it's a glorious sight to behold, those guy like aero, and know how to apply it.

also, there's a lot of gems in here, including a plywood splitter that takes 4 nuts to remove..

Comfort! Is the aero really faster or does it make you feel more comfortable so you go faster? We are racing big bricks SUV's with wings. Yeah I guess thereis some aero there but...

Its definitely makes you more comfortable.... But no doubt in my mind that you are on the power sooner, so that means faster.... biggest draw back is being stuck behind a car thats only faster on the straights.

 

[Grant 302]

Lol. Yes, ‘aero’ is faster.

If F1 was completely open regarding aero, most of the money would be spent on odd things like disrupting the air for the car behind you and dealing with dirty air from the car in front of you. No thanks.

Our version would be more to do with canned beans consumption.....

It's a funny balance, generally more wing will kill the top speed, but if it allows you to carry more speed coming off the corner, then it more than makes up for it, plus the additional turn speed. This is why I say let someone else develop it and just copy or buy that design. Going down this road on your own can become a rabbit hole.

This is why the Pheonix guys almost always come out on top. I'm having a good day if I can stay on the lead lap with AJ, Calvert, or Rezzantano.

If this trend continues, carbon fiber splitters may be cheaper. Lol.

I think I would agree with you if I had a less limited budget.. But getting things shipped down here plus taxes etc, adds 50% to anything that I want to import.

On the wing, went crazy at first with a 10 degree angle,,, then a 5 degree angle ,,, and now at about 3 degrees. Probably try a zero angle next time out.

 

[BKBoss302]

Can't resist a good wing and splitter thread. Currently running 3 degree wing angle and as many hood vents that TrackSpec makes for this hood.

The part I like best about adding a wing (besides the obvious) is when cresting a rise in the track like turn 1 at Laguna for example. The car would get very nervous and spin the tires if allowed so' I'd have to let off the gas and wait for it to settle before picking it back up. Adding the wing and some AOA makes it a flat footed corner now which is way more comfortable as well as a faster experience not to mention that my tires last a good bit longer.

@AJ Harman is laying my wing up as we speak. Looking forward trying it out. He was also a good source, since he asked what I had for splitter etc... and then he told me what he would use on my car. Nice working with someone that could have sold me something larger that would have cost more and caused issues.

AJ is good people.

Yep, I'm a fan of Hartman stuff as well
