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.

Back up and Running
Thursday, November 8th, 2012Setting Up a Seven – When things just work
Tuesday, October 19th, 2010I 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 
Health benefits of Autocrossing
Monday, July 20th, 2009At 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. As the run progresses you can see it quickly rise all the way to 145 bpm by the end of the 45 second run. Just as interesting is the way his heart rate falls as soon as the run ends and drops to the low 130s just 10 seconds after the run. So now if anyone asks you why you autocross just say its for the health benefits 
Unfortunately the video quality is not as perfect and the heart rate only updates every 5 seconds but all in all it was a successful test of the system. I have already ordered a Polar RS800CX (1 sec resolution) and I plan to run this same setup for the duration of the Lemons race at Buttonwillow next month. So stay tuned for the health benefits of endurance racing

2nd fastest time of the day
Monday, April 21st, 2008My prize for the second fastest time of the day at the opening GGLC Autocross of the season.
I ran a 53.139 and was only beaten by a race-prepped Evo running slicks. The prizes did not include the instructors times though I was actually faster than all but 3 (Jason and Alex on RA1s and Rob on slicks) of them as well. My goal for the season is to beat Alex with the added incentive that I will be upgraded to instructor if I do – seeing that I already beat his time in the morning session yesterday I am pretty confident I can do it again. I just feel sorry for my future students
Thanks to norcalturbo for this photo of me from the morning session.
GGLC Autocross
Sunday, November 4th, 2007Some in-car video from yesterdays GGLC autocross in Marina.
The first video is my fast lap for the day. I don’t slow enough after the slalom and understeer into a cone. I still end up doing a 40.1 (+1).

The second video is from my last run of the day where I am sideways on at least 3 occasions. It was a slow run (41.6), but great fun nonetheless

The last video is Nithyas best run (46.5) of the day in the GTI. For someone who almost backed out of her first event, she is becoming very good at this. If you have never tried autocrossing you should come down to one of the GGLC events next season and give it a try – it is safe, fun and the best way to learn car control.
