Off topic but does anyone know if Rick Perry's car will be at MHX in September?

Rick Perry(governor?) or Mark Perry

If you are talking about Mark (and I think it's a fair assumption)...I don't know if they were planning to do that trip or not? I'll check...but I am thinking that's a no.

The only discussion I heard was maybe a trip to colorado for the FM gathering.

Bumping this for updates - interested to see what you came up with for mounts, pics of the wing mounted, and your impressions about it.

Here's the mounts a local guy fab'd up for me. They mount with two bolts into the trunk gutter.









Impressions: It's big, black, and shiny. Car is about 2-3 weeks away from being road worthy and then it will be snowing.

Nice!!! Thanks for the pics. I'm looking at picking one of these wings up soon. Heck, those mounts look like they would do the job and I could make some like that...

Haven't seen many guys who have actually run this wing to give input on how well it works, but it is a $3k wing after all, I think it should work well enough.

What do you plan to do with the tethers?

Those two have a lot of similarities.

Dr Pooface

I'm going to remove them for now. I think they are attached to the end plates but I haven't taken it apart yet.

I just won a COT wing on ebay so I'll be tackling mounting this soon

I forgot to post details to this thread, but I used this wings and made up some really simple mounts at home. Details here:

I'll try and find time today to grab a quick screen capture to get the coordinate locations for the hole pattern for anyone interested.

I'm definitely interested in this, thanks.

Also, if you've got any pics of the car overall with the wing mounted, I've measured and visualized but it'd be nice to see exactly how the dimensions of the wing fit with the car.

I took the tethers out and just set them off to the side. It is an easy operation, maybe 10 minutes or so.

The wing is GREAT. It definitely works, and makes good down force with much less drag than my previous dual-element. The car gained a lot of speed at the end of the straights from the reduced drag. Overall I am very happy with it and will definitely be using it again next season.

I'll try to grab a picture of my wing mounts. They are a bit ghetto compared to the ones above but they work.

Dr Pooface

To those pm'ing me my fab guy isn't into making uprights for cars that aren't local. Sorry.

I don't have enough posts to respond to pm's yet...

It shouldn't be hard for a person to find someone local to them to make wing uprights. If I were not into DIY myself, I would just throw together a design and have it CNC'd.

CNC adds unnecessary costs, we were just doing water jet with the previous ones.

Work finally slowed down...I am back working on track car which means I should be able to get something drawn up.

I'll make this a priority of the next couple of weeks. Formula 1 is this weekend so won't get to look at it until next week probably.

Dimensions are in millimeters. If someone wants to host the file, I've got a PDF that could be printed out to make things way easier, especially cutting the profile.

I wasn't super confident in my measurements for the angle of the rain gutters in the trunk, so I ended up leaving out hole A2 when I initially made the mounts. I just got the car on reasonably level ground and mounted the wing with the A1 holes so it could pivot, put the wing in the 0 degree adjustment hole (can't remember if I used A5 or A14 for 0), then had a buddy hold it there while I tightened the two A1 bolts so it couldn't move. Then I just drilled through both pieces at once to create the A2 holes. I don't have any measurements on the pieces of angle, but there was nothing complicated about them. I used the mill at work to slot the holes for bolting to the rain gutters so that it would be easy to get the two pieces parallel, but if you're careful you could do it without slots.

The final position ended up a little farther forward than I like. Will definitely be moving it back as far as possible on the angle if I keep using this setup.

Sharpen the leading edge of the spoiler brackets?

ThePass

iTrader: (3)

What is the correct way to measure the angle of the airfoil? Do you put a straight edge on top of the wing so it rests on the back and front edges of it and use that line? Or are you supposed to measure from some centerline through the airfoil?

jpreston - in your pic the wing looks like it's pretty horizontal (zero degrees) is that the case?

-Ryan

ZX-Tex

iTrader: (15)

You can do it either way, as long as you measure it the same way each time, and take notes on what angles work for you under whatever conditions. Personally I just lay a digital level across the top of the wing and measure that.

Ideally AOA is relative to the centerline of the wing and that is what you would measure. But then again, you really do not know the incoming angle of the oncoming air that is hitting the wing due to the shape of the airflow over the car. Unless the wing is really high, the roof line is coming into play.

What zx-tex said.

I can't remember if I ran it at zero degrees or +1.5 degrees (angled up). The first session I tried it was at -2 or -3 degrees, and the car understeered like hell. Without a front splitter, the car was decently balanced but still had a little push at 0 degrees.
