So, I did several runs today. The first was stock and reached 84 mph @ check point 12, and 36 mph on the uphill section at check point 14. Elapsed time from a dead stop was 1:57.9 minutes. I tried rolling starts from numerous speeds. The cool part is that with the HUGE drag at the high speeds; it should be easy to measure changes in drag, both for mostly linear rolling resistance, and the aero drag.
I taped a box on the same spot on the "wing" that vortex generators are typically put on airplanes (see pic below). I expected some small change, but it actually limited the speed to 73 mph !!! Woo hoo !!
Now, I can swap out tires, change ride height, tape on aero mods, and other fun projects. Let me know what I should check next!
