Thursday Night Open Lapping

Thursday, August 31

High Plains has offered Thursday night open lapping for the last two summers. I’ve been wanting to do it but somehow never made it a priority. They run a hot track from 5 to 9pm. Last week Scott asked if I wanted to go. I pondered it a day or so before responding in the affirmative. Scott and Mark met me at the park and ride.

I’ve never lapped at night and I’ve never lapped in wet conditions. With sunset at about 7:30, I would certainly get to drive in the dark. And this time of year is perfect for evening thunder showers on Colorado’s eastern plains so I felt there was a better than even chance of some rain.

Heading east on I-70 we could see a dark cloud above Byers, dropping rain from one end. We had to stop at the gas station for fuel. I pulled up to the pump but stayed in the car. The roof isn’t exactly rain proof and I had a couple of big leaks dripping on the sills. I was pondering how long I’d sit there, delaying the inevitable drenching, when the rain noticeably slackened. Even though I sat in the car while the gas pumped, my shirt got pretty wet. Which, in turn, caused all the windows to fog up.

Mark and I were fueled up but Scott hadn’t started yet. So we ditched him, Top Gear style, and headed to the track. A couple of miles down the road we were out from under the cloudburst and back on dry roads.

I didn’t get a car count, but we had a small enough turnout that we didn’t run any groups.

I may have been the fastest car on the track when I headed out the first time. Nobody ever passed me, and I passed six or eight cars. It was sprinkling a bit; for a short time I had to put the wipers on intermittent. The track surface never got wet. It never was wet enough to glisten. But every now and then, I could feel a little loss of traction.

I guess it was a little perverse of me to want it to rain. There were a few showers in the vicinity, none likely as wet as what we had at the gas station. They’re happy to run the track in the wet, as long as no nearby lightning endangers the corner workers. But although lightning occasionally flashed on the horizon, neither lightning nor rain was an issue tonight.

I finally got a working suction mount for the phone. The last few track days I’ve had to keep the phone in my pocket where I can’t see it. It’s a big help to get the immediate feedback on what you’re doing. I tried changing my line through one turn. Run a couple of laps the old way, then a couple the new way and see whether I’m gaining or losing time.

During my second session they had to deploy the tow truck to collect a stricken BMW between turns 6 and 7. I was expecting it to take a lap longer than it did for them to complete the operation. The tow truck was on the move before I got to the start/finish line. As I approached turns 1 and 2, the yellow lights were getting turned off. I passed the truck on the highway straight. Next time around, he was hooking up the car. He took the short-cut at the top of the hill and were off the track by the time I came back around again. That’s something like eight minutes. Very efficient.

After the second session I opened the boot lid to find my battery out of its mount, laying on its side. I got lucky here. I’ve seen pictures of rear clams damaged by a loose battery. It can cause serious damage. I never heard it banging around and there’s no damage I can see.

The bracket had not come loose, the battery just popped out of the mount. I attempted a repair but was unable to get it secure. So my day was done. When I expressed my disappointment that I didn’t get to drive in the dark, Scott, the generous guy he is, offered to let me take a few laps in his car. Twist my arm.

Although I’ve ridden in many Elises, this is the first time I’ve driven one other than my own. It’s only the second car I’ve tracked that isn’t mine (the Mazda Chump Car being the other). Scott’s car is supercharged and he’s on better tires. I had my doubts about the tires, though. They had been stored in the cold over the winter and I’ve heard bad things about that. Also, the suspension is different, his being standard and mine being track pack.

He gave me the keys and said, “Don’t break it! Try to do more like a 2:20 than a 2:13.” I ran a few laps. I had the phone in my pocket, so I couldn’t see what my times were until I was out of the car. My first impressions were how different the car is. The seats are different (mine are cloth, his are leather). The clutch had a different feel, he’s got a different shifter.

And the most obvious difference is the power. I never pushed the car. I short-shifted and was on the brakes much earlier than usual. Even so, I was often in fourth gear in places where I’m always in third. Turns out I did a 2:17 and topped 119mph on the highway straight. That’s 10mph faster than I managed in my car tonight. Without pushing it.

I was really looking forward to driving in the dark, and would have enjoyed driving in the wet, but missed out on both. I was hoping to get four sessions, which would have made the event about half the cost per lap as a day with CECA. But with the mechanical failure, I only got two sessions so it was back to par.

Battery

Turns out it was an easy fix – I didn’t realize the lip on the base of the battery was not symmetrical. If I’d turned it around 180 degrees I’d have been in business. I had the battery replaced on my trip to Austin in June. I’m wondering if it was installed improperly since then. If so, it managed to sit tight for about three track days (COTA, La Junta, and the RAKC lunch laps).

I’ve seen photos of damage done to other people’s Elises due to the battery flopping around in the boot. I’ve had a good look and don’t see the slightest sign of damage to my car. I’d say I dodged a bullet.

Turn Signals

From the time I bought the car, the left turn signal has blinked at twice the rate of the right. Some have said this is an indication that the turn signal will fail. It kept working for me for quite a while. But for the last five years or so the left rear hasn’t been working. I’ve tried a couple of proposed solutions without finding a fix. I was told that the entire unit needs to be replaced. There are two problems with this answer. First, the parts are about impossible to find. Second, the assembly is quite expensive.

So I’ve been using hand signals. I still use the signal, as the front works okay. I just use the hand signal when there’s somebody behind me.

Last week on the way home from the LoCo picnic I noticed that the left turn signal was now blinking at the same rate as the right side. Back home in the garage, I got out to look. Sure enough, it was working! As I stood there watching, it began to alternate between blinking slow and fast. The joy was short-lived, though, as it quickly went back to blinking fast and not working. It worked for perhaps two minutes.

On the way home from HPR it worked for the entire drive. It has failed again since then, though, so I’m back to hand signals. I find it odd that it doesn’t work for years and now all of a sudden decides to work every now and then.

Tires

I bought Yokohama tires last year for track days. I got four days out of them. The rears are almost slick. The fronts have tread, but I’m pretty sure they’re heat cycled out. I expected to get at least six days, so I’m pretty disappointed. On the first of those four days I recorded my personal best lap time at HPR: 2:09 and a fraction. Since then, a 2:14 has been my best. I’ve managed 2:14 on the Dunlops, so I’d have to say my disappointment isn’t limited to their longevity.

So now I’ve done a 2:13 with the Dunlops. That’s with a full fuel tank and a light rain falling. I’m certain the 2:09 is out of range on the Dunlops. But I’m out there lapping for fun, not to win any races. I see no reason to buy sticky track tires. I’ll see what I can get in the 300 treadwear range. A little stickier than the Direzzas, but should last a good long time if I use them only for track days.

The Video

When I’m searching through YouTube for track videos, I tend to whine if they don’t have any gauges, track map, or timer. So I’m being a naughty boy by not having any gauges or a map in this day’s highlight reel. And it only has a lap timer because you can see it on my phone.
