markrolston@mac.com 29 Posted August 27, 2020 Author Share Posted August 27, 2020 Crunch time! Still planning to test/tune in mid September and drive it to Nismo Fiesta in October. Shift actuator installed the transmission. Driveshaft arrived. Fixing leak on cam covers and while they are off we'll repaint them with a nice speckle red. I always loved the way Ferrari intakes looked with that texture. Lastly I'm converting the 3D printed canards into a mold to make carbon fiber parts. 1 Quote Link to post Share on other sites
markrolston@mac.com 29 Posted October 3, 2020 Author Share Posted October 3, 2020 one more week to go before Nismo Fiesta. There's a lot still to do. I really only expect to get it put back together and running to be able to get it down there. Real test and tune will have to wait. 1 Quote Link to post Share on other sites

Do you still drive the RBZ much? yes. actually just spent many months doing some reworking of the engine after blowing it up at COTA. I'm hoping to bring both to the show.

markrolston@mac.com 29 Posted October 8, 2020 Author Share Posted October 8, 2020 The car is coming back together but not done so I will miss this weekends NISMO Fiesta in San Antonio. Engine is running roughly and we think it's a stuck exhaust side VVT. Going to replace it with a part that fixes cam timing in place on the exhaust side. Quote Link to post Share on other sites

markrolston@mac.com 29 Posted October 12, 2020 Author Share Posted October 12, 2020 The 3D printed real panel just arrived. I had to send it to someone with a large format printer and even then it came in 3 parts. We will have to adjust the position of the lights a bit to get it mounted correctly. For now I'm going to leave the red/white paint showing behind it, despite my original plan to black out that area. It looks pretty cool in person. It's easy enough to change it to black later. 1 Quote Link to post Share on other sites
markrolston@mac.com 29 Posted October 22, 2020 Author Share Posted October 22, 2020 Car is on the dyno. On basic tune so far making 460 with only 9lb of boost. More to come. PXL_20201021_211103037.mp4 Quote Link to post Share on other sites
markrolston@mac.com 29 Posted November 6, 2020 Author Share Posted November 6, 2020 doing some final testing....(it repeats the dyno clip but there's more) 1 Quote Link to post Share on other sites
260DET 32 Posted November 20, 2020 Share Posted November 20, 2020 Just to stir the pot and seeing that you do outrageous mods, the go now is to fit a dual clutch transmission from, say, a BMW. Aftermarket support for this sort of conversion is coming on so no excuses LOL. Quote Link to post Share on other sites
markrolston@mac.com 29 Posted March 5 Author Share Posted March 5 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 lid of someones Mustang. Obviously I am going to reinforce the mounting of this thing.

markrolston@mac.com 29 Posted March 26 Author Share Posted March 26 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. Quote Link to post Share on other sites
markrolston@mac.com 29 Posted March 26 Author Share Posted March 26 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 Quote Link to post Share on other sites

budgy 6 Posted April 13 Share Posted April 13 Those LED tail lights look incredible! Quote Link to post Share on other sites
markrolston@mac.com 29 Posted April 29 Author Share Posted April 29 (edited) 3D parts for the tail lights arrived. Also got some controls mounted to the wheel. DRS, traction control, boost, display page, horn... Edited April 30 by markrolston@mac.com Quote Link to post Share on other sites
Ben280 13 Posted April 30 Share Posted April 30 Oooooo dials. Love this car! Quote Link to post Share on other sites
markrolston@mac.com 29 Posted April 30 Author Share Posted April 30 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. 1 Quote Link to post Share on other sites
rossman 19 Posted May 1 Share Posted May 1 (edited) The tail lights looks pretty cool. What's your plan for the center opening? You mentioned air flow. Where is the air coming from and how's it going to get there? Edited May 1 by rossman Quote Link to post Share on other sites
