Health benefits of Autocrossing

Monday, July 20th, 2009

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. 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 :-D

Lotus Elise on a Go-Kart track

Sunday, February 8th, 2009

I’ve just helped the Golden Gate Lotus Club launch the new GGLC blog and as the guest editor I’ve had the honor of making the following first post.

One of the highlights of the 2008 West Coast Lotus meet were the time trials that were held at the go-kart track of Jackson County Parks facilities. You often hear that the Lotus handles like a go-kart but this was the first time that I got to drive my Elise on an actual go-kart course. Our run format consisted of running 3 back to back laps on the outside of the track to count as one single timed run. It was an interesting day and we got to to run the first session in the dry before the rain came down creating a very wet second session.The following video combines in-car and external footage of my first wet run of the afternoon. Major thanks to Rob and Jen from Dietsch Werks for taping the run from the outside.

Since my R-compound tires were completely slick I had to swap to my AD-07 street tires for the first time in six months. The combination of skinny tires, street compound and wet surface meant that I had no grip and I almost went off while braking for turn 1 (I was later riding with someone who shall not be named when we actually went off at the same spot :-) ). I make the turn with about six inches to spare and am pretty cautious and slow waaaay down for turn two only to find the rear end wants to fishtail on the exit. Turn 3 went much better but the lack of front-end bite at turn 4 lead to a few NSFW comments. At this point I slowed down even further and tiptoed my way around the course for the rest of the run. We later found out that the county had repaved about half the track which meant that the course had sections with both old and new asphalt which account for the wide variance in the grip levels at the turns. Turns 1 through 4 had the lowest grip and you had to tiptoe through them before getting on the throttle for the rest of the course.

The next video is incar from my final run in the dry. The lap is much better and doesnt have too many mistakes apart from a missed shift on the start of lap 3 – I believe it ended up being the second fastest Lotus time of the morning.

Lotus Elise Supercharged

Friday, February 29th, 2008

Chris Harris review the new Supercharged Lotus Elise – me wants to upgrade :-)

Harris is one of the best automotive reporters out there – he strikes an excellent balance between the humour of Jeremy Clarkson and the driving ability of Tiff Needell. If you liked that review I highly recommend the Chris on Camera series where he reviews a different car every week.

2 Years and 33,500 miles later my luck has finally run out

Sunday, December 2nd, 2007

02122007891

Got rear ended at a red light today. No injuries though it looks like the rear clam will have to be replaced. The other drivers insurance has already accepted liability, now I just have to hope I am not without the car for too long.

GGLC Autocross

Sunday, November 4th, 2007

Some 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 :D

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.

Photo in SCCA SportsCar magazine

Tuesday, July 3rd, 2007

My first magazine photo

One of the photos I took of my dust covered Elise has been used in an SCCA RallyCross ad in the July Issue of SportsCar magazine. And no I do not RallyCross my Elise – the dirt was a result of my Reno-Fernley spin. It was taken with a Nokia N95 and looks remarkably good in a full page print advert (proof image here).

This happened a few weeks ago but I only just got around to blogging it :-)

One lap of Reno-Fernley Raceway (N95 video)

Wednesday, May 30th, 2007


Lap of Reno-Fernley Raceway (Nokia N95) from rnair on Vimeo

I finally got around to editing and uploading some of the video* I recorded during my last trackday. This was the first time I was using the Nokia N95 and I had high expectations from the high-rez camera. As you can see over here the video quality is dramatically better than my past recordings from the N73. I have been planning on getting a ChaseCam PDR setup for a while but now that I can get such excellent video from the phone I think I will stick to my homebrew cellphone setup. There are still some issues with vibration on the high speed straights but I am confident that I can fix that adding a layer of padding (tissue/cloth) to the phone before taping it to the car.

*This video is only to show quality of the recording – the driving still needs some work :)
