Pat,
I was thinking last night, if not big on the Star Wars theme, a cool name for your car would be "Blackbird". The SR-71 (or SR-951) comes to my mind when I look at your car![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

Did some more testing yesterday. Amongst other things we found that by increasing the angle of the 2nd smaller vane on the rear wing we gained top speed down the main straight! Riddle me this?

Patrick: what were your corner speeds?
Not knowing the track or conditions, I'd wager you got into the range of optimum efficiency on the wing: a multi element wing at low chord angles will be less efficient (L/D) than a single element wing at the same chord angle. Increase the angle and the multi element wing becomes more efficient.
So you may have been able to carry more speed thru the corner leading onto the straight and since you actually gained some efficiency you were able to carry the better run through the entire straight.

What happens when you turn it completely the opposite way?

Car looks fantastic and with that 3.1L it must be a TQ monster. I must get mine running again , love your rear wing, I might end up trying something like that on the carrera ...

We have only been running 1.3 bar for the moment. The car is pretty quick as is. There's a lot of room for improvement too. I always like that feeling as we know there is more potential to eek out in the future.
Great to see these cars still getting built in all corners of the world. How good would it be to bring them all together one day.
Here's another recent video of Richard in Holland. That car looks pretty nicely hooked up....well except for that little glitch that just cost him the win!

Not the track we will be running on in Competiton in 2 weeks. That is faster and more flowing.
Drag and downforce would have increased with the more aggressive attack Elliot but as there was greater corner exit speed, this overcomes the extra drag.

Our car was just over a second quicker (on a 60-65 second track) than a 997 Cup on Michelin slicks yesterday. We're on Medium compound R specs. Testing has been very promising.

The Ashes weren't quite as bad as the results suggested. Beaten by a better team at the height of their powers on their turf with the home ground pitches to suit. We've had a lot of injuires to our quickies. Need to build for the future.

The difference between the 1st test day and yesterday was that we raised the the front ride height a little as the springs had settled. We have to be 65mm above the ground at resting ride height. We knocked a little bit out of the front camber so it’s back to just over -3^. Raised the rear ride height a little yesterday and wound in some rear sway bar. The corner speeds were quicker which translated to the improved straight line speed. The only thing I didn’t confirm was how it changed the downforce at the same part of the track.

Shown in #755 Nathan. That's to the wheels at 1.5 bar. Currently we're testing at 1.3 bar to be on the safe side. As you can see, we're also leaving quite a lot on the table.
