In my previous post about the Evora S on track I spent a lot of time complaining about the 400 treadwear tires that the car was on. I was getting a lot of tire lock under braking and the car generally did not have enough grip on the track. Luckily I was then able to replace the tires with a set of Michelin Pilot Super Sport tires on the optional forged “sport” wheels for the Evora and hit Laguna with the GGLC once more.
As you can see from the video I was able to pull a 1:48 lap without really maximizing any of the turns.… Read the rest
I had the pleasure of attending the inaugural Formula 1 US Grand Prix at the Circuit of the Americas last week and want to write up my thoughts after the event. This is not a review of the race itself but rather a review of the venue from a fans point of view and how it compares to other race events I have been to such as IndyCar (Infineon), NASCAR (Infineon) and the 2002 F1 USGP at Indianapolis.
Getting to and from the track
Having read nightmare predictions about parking at the race I decided to use the free park and ride shuttle from the Travis Expo center instead of shelling out $200 for a parking pass.… Read the rest
Celebrating the fact that the Seven is up and running with an autocross video from Marina. The car still has an intermittent misfire that I am trying to iron out but it is running well so far.

Timelapse video of 3 Elises driving back from Lotus Owners Gathering 31 (LOG 31) in Vegas back to the Bay Area through Death Valley and Sonora Pass. Route chosen by Steve M and video by John Z, I just tagged along to make up the numbers 🙂
It was a spectacular drive with Sonora Pass (skip to the 3:10 mark in the video to see footage) with almost no traffic and excellent asphalt quality. The pass is closed for significant portions of the year due to snow so you should call ahead before you make the journey. Full route info below:
Cross-posting the interviews I conducted for the GGLC at the LA Auto Show and originally posted on the GGLC blog:
GGLC attended the North America launch of the new Lotus range at the LA Auto Show and got a chance to speak to senior management about their plans for Lotus and the challenges in launching 5 new cars in a short span of time. Short descriptions of the interviews and their major points are below but we recommend you watch the actual videos to get a sense about the future direction of Lotus
First up we spoke to Dany Bahar, the CEO of Group Lotus about his vision for the future of the company and why they were launching so many cars in such a short timeframe.… Read the rest
I have made a long list of modifications to the Seven since my last blog update which I still need to document on here. In the meantime I wanted to share this video from the GGLC autocross on Saturday (watch in fullscreen).
The Seven may be unreliable, impractical and difficult to live with but the few days like this when everything works are absolutely worth the hassle. Incidentally we found the reason for the surging idle it ended up that I couldn’t drive the car for the rest of the day 🙂… Read the rest
The fact that I have been using various Nokia phones and attending multiple Iron Maiden concerts (5 at last count) over the years led me to this amazing demonstration of the improving audio quality of Nokia cameraphones. While I have been a big fan of the N95 camera but I always complained about the audio quality when recording video in loud environments. This video that I recorded at the Iron Maiden show in Concord in 2008 shows how the N95 struggled with clipping and noise issues when the environment was too loud.
Now fast forward 2 years and I went to another Iron Maiden show in Concord a few weeks ago with an N900 and recorded the following video clip.… Read the rest
After going through many of the initial setup issues on the Seven and giving it a quick shakedown at Laguna Seca, I decided that it was time to take it on my first road trip. I drove it down to Buttonwillow Raceway Park to join a group of other Se7en owners for a track weekend. The fact that there were going to be other owners there made me feel more confident that there would be enough mechanical expertise to solve any mechanical issues that may crop up. Having been to Buttonwillow once before, I knew that the heat would be brutal and was glad to pitch in with the other folks to share a couple of garages with the other folks.… Read the rest
Fatigue – that’s a word you hear being thrown about a lot at endurance racing events. We know that as drivers do long stints behind the wheel, fatigue starts setting in and the lap times start to drop steadily. But the $64,000 question is how long can a driver stay out on track without compromising the performance of his/her car or the safety of the other competitors. People keep throwing around the statistic of F1 drivers having an average heart rate of 170 bpm for the 90 odd minute duration of the race. That data might be useful for a young fit F1 driver who spends the entire duration of the race on the ragged edge, but is not very relevant to the average Lemons driver who is generally older, considerably less fit, often drives longer stints and (speaking for myself) is generally well under the limit.… Read the rest
At the last GGLC autocross Alex and I decided to try out a little experiment to see how your heart rate changes during the race. We used a Polar S720i to record his heart rate, an iPhone for video and a DL1 data logger to record G-force and speed readings. I used some simple PHP magic to sync the two data files together and used the Chasecam Dashware system to create this finished video.
You can see the speed, heart rate (BPM), longitudinal G (acceleration + braking) and lateral G in the dashboard on the top of the video. His average heart rate was in the low nineties while on the grid and rises to to 101 just before the start of the run.… Read the rest
