  1. I took the car to Zcon in Colorado Springs a few weeks ago. Nice to see so many z-cars in one place. While I was there Larry Chen did a quick video about the car. It was cool to do a complete walkthrough of the build.
  2. Took one last picture before loading the car up tomorrow. Looking forward to Zcon, especially getting some track time now that the car feels sorted.
  3. getting ready for Zcon in two weeks. Almost all done (never completely finished. ever.)
  4. extraction: hood vents and the fact that the entire front end is just a tube frame. If that doesn't do it then down the line I'll put in some side vents and wheel well vents. But at the moment, I'm confident that basic shielding of the turbos will do the trick.
  5. I got some serious track time last week. It turns out the turbos and downpipes create some serious heat on the hood, despite the open space in the engine bay. I'm going to have to wrap them and come up with a nice shield. Too bad since it looked cool uncovered. Anyone going to Zcon in Colorado Springs this coming August? I'm trailering the car up there now that it's more or less finished.
  6. Still working on the lights. Rest of car is done. Going to make some videos soon to walk through the build. Also just registered to bring both Z's to the August Zcon in Colorado Springs. Should be fun.
  7. thanks for the advice. I'll certainly do some testing first. Anything I do will first need to be subtle enough to not force a drastic change in the classic form of the car. I'm trying to tread a narrow path between modern tech and an old-school car.
  8. thinking of opening a hole in the wheel well then fabricating a tunnel from there to these lights.
  9. Here are the lights in the rear panel. We still need to polish and clear coat the outer surface. I'm confident with final fit and finish this will look beautiful and still fit the overall design story of the car.
  10. 3D parts for the tail lights arrived. Also got some controls mounted to the wheel. DRS, traction control, boost, display page, horn...
  11. almost done tuning the transmission (shift/throttle timing)... IMG_0405.MOV
  12. And speak of tinkering...3D printing my own parts is amazing. I made a custom tail light assembly that will allow air to pass through the middle of it. It's the same outer shape as stock but is really just a deep ring rather than a flat panel. Shown here is the CAD assembly and an example of the LED we will put in it. It's clearly not stock but should be a nice update to the original design aesthetic. Also included is a shot of the inspiration behind the design from a GTR. IMG_4896.tiff
  13. so the car is technically finished. Yet I keep tinkering with it. This week we managed to Dyno and tune the car beyond the turbo's native spring pressure. It made a bit more power with almost 600whp and tq. At <2500lbs this much power is just fine and a good safe range for heavy track use. We will be at Harris Hill Wednesday to button up the sequential' shift maps, traction control, shocks, and the wing's set positions.
  14. The car is running and getting more refined. I had entered an event at COTA a few weeks ago but then Austin had that terrible freeze and I missed the event. In the meantime we've been able to finish the adjustable wing, using the mechanism and sensors from the Victor Racing wing setup. We took their hardware apart and installed it nicely into the rear hatch assembly and came up with our own mounts. The programming will allow for basic flat aero, a slight downforce for turns, and a big tilt for aero braking. I've seen these at work at previous events and they work so well they crushed the deck
  15. doing some final testing....(it repeats the dyno clip but there's more)
