Thursday, September 17
Due to 2020 being generally shitty, this looks to be my only track day of the year. It could be argued that, if I had any sense, I wouldn’t even do this one day. A paranoid person might think that it is tempting fate: why give 2020 additional opportunities for mayhem?
The original plan was that I’d have a guest. For a while it looked like one of my track buddies would attend as well. None of that came to pass: my guest messed up his back last weekend and my track buddy decided to be a responsible parent and attend a parent-teacher conference. So it goes.
I arrived early because I wanted to be relaxed in my preparations. It seems whenever I have any time pressure, I mess something up. Never anything serious, but I prefer to have things go smoothly. So I had a bit of time to kill. If the food truck had been open, I’d have spent some of the time eating. I brought a snack with me, but not a meal.
We are typically split into fast and slow groups. I picked the slow group. When I signed in, I asked if we had enough cars to do this. It seems we did. However, during the drivers’ meeting, we were told that the number of entrants was marginal. We’d do fast/slow groups the first hour and after that, we could run as we pleased. Judging by wristbands at the meeting, I guessed there were more slow cars than fast ones.
I was the only Lotus.
The track’s website listed rules for COVID: only people in your own household could be passengers; social distancing should be maintained; masks are required when not wearing a helmet. It didn’t appear that these rules were being enforced. Few of my paddock neighbors wore masks, and some even attempted to shake my hand when introducing themselves.
The weather was ideal, unless you count the smoke from the forest fires, be they here in Colorado or on the west coast. There was no obvious smoke smell, but the haze was significant. The temperature was pleasant and there was no breeze to speak of.
The slow group was up first; we’d have a half hour, but by the time the meeting was over and I made it out on track it was more like 25 minutes.
This is the first time on track since the engine replacement, lighter flywheel, rear brake pads, and new diffuser. I didn’t notice any particular difference, but it has been nearly a year so it’s not a good side-by-side comparison.
I had some considerable traction issues that I’m blaming on tire pressures. (That said, I didn’t change pressure in any sort of attempt to correct the problem.) The real issue of the evening was my brakes. Midway through that first session, my brake pedal started getting long. Brake fluid level was okay. The problem is most likely old fluid. The brakes cooled down between sessions, so things were okay at the start of each session and I’d have increasing fade lap after lap. None of my sessions was very long, so this was an annoyance and something to be closely monitored rather than a significant problem. I can only think it would have been much worse on a regular summer track day when the ambient temperature is twenty or thirty degrees higher.
When I went out for my second session, the check engine light illuminated. I came back into the pits immediately and checked the codes. I had two: P0463 and P1302. P0463 is “Fuel Level Sensor Circuit High Input” which indicates a fuel level that exceeds the fuel tank’s capacity. I filled up in Byers but didn’t fill more than usual. Certainly, after 17 highway miles and 8 laps, I wouldn’t expect this code. I’ve had the P1302 (misfire) once or twice before. I cleared the codes and went back out. If they returned, I’d call it quits. They never did.
I ran a short third session. I would have liked to have gone longer, but was limited by my brake problem. I called it quits after that, as the sun had dropped below the horizon and I figured that by the time my brakes were sufficiently cooled, it would be too dark to put in any good times.
My best time was in the first session, 2:13.40, which I think is a decent time for the street tires. Not spectacular, and I won’t bother putting that lap up on YouTube. Today’s video is mercifully short. This time of year, the sun sets directly over the highway straight. This would normally be quite bothersome, but with the smoke it’s not an issue at all. The camera doesn’t do the scene justice.
And there are my two errors, both exiting the corkscrew. First, I’m too abrupt when pulling out to pass the M3 and I get quite a wobble. The second time, I hit the curb, unsettling the car and causing me to put two wheels off. (The guy behind me on that last one caught it on his camera, but hasn’t sent me a copy yet.)
At least my brake pads are quiet now. (These pads handle high heat, work when cold, are relatively dust-free, and quiet. Except when brand new, when they sound like a locomotive horn when coming to a stop. They need a track day to get quiet.)
Considering how few laps I ran, I was surprised at the physical toll. When I got home, I was quite fatigued and the next morning I had a few more aches and pains than I was expecting.
