Black magic Mk5 GTI track car
rex:
That rear wing is very, very sexy :happy2:.
I wish I had no engine problems so that one of these would be in my garage right now...
I am curios to see how you make the mounting points.
Keep up the good work!

Agree with your calculations and estimations.
Hope it works well and the engine does too.
:drinking:

Will come back with pics once everything is ready ! As for the engine I'll have to do another check to see what's with the rough idle. Don't want to risk anything after what happened to me on Hungaroring. BTW, it seems the Evoms heat shield was touching the plastic water T-piece that broke so I had to cut a little bit from the shield to clear the pipe !

Because I wasn't inspired to measure the distances and diameters of the holes on the drop tabs of the wings, I had to approximate them by measuring on the computer's screen and suipposing the 3 small holes have 6mm in diameter. At first I did not understand how can the 3 inclined holes pass through the same point on the mount tabs while rotating the wing around the elongated hole. After making a quick drawing in Acad, I understood that if you rotate and translate the wing around the elongated hole, it is actually possible >

From the pic it can be seen that it's possible for 2 fixed points found at a distance X one from each other on the mount tab that I will manufacture to be on every one of the 3 inclined holes if the axxis between them will rotate and translate at the same time (the 3 values are different because of the way I've measured the distances on the computer's screen instead of on the wing itself). By measuring the angles between them, one can see that between the min and max position there's about 5 deg. At first, I told the guy to install the wing in such a manner that the min position is 0 deg for street driving and no drag. However, after drawing, I realised that a min of 0 would mean a max of 5deg wich is too little. Thus, I will establish the min position at 4-5deg so that the max can be 9deg. (the drag and absorbed power for this wing is not something too scary > about 3kg and 2HP)

Indeed nothing to worry about.
When you do the invest in such a wing the main point is you get the downforce to want on track. :wink:
Increasing fuel consumption by 0.1 or 0.2 l per 100 km - :fighting:
Nevertheless in turbulent air things are quite complex. Promises and estimations are hard to make.
