My Neighbor’s Car

Charlie has owned an AC Bristol for 50 years, and used to race it. I got a quick peek at it today. It looks pretty much like this picture, but it’s (aged) red.

The car is also known as the AC Ace Bristol. “Ace” refers to the model of the car, and “Bristol” refers to the engine, a straight-six based on a pre-war BMW design. The AC Bristol is a predecessor to the Anglo-American car known as the AC Cobra.

Update: Looking around the web, I saw a concours winning AC Bristol listed for sale for £225,000. Charlie’s car looks to be more in the “preservation” category than the “restoration” category. Restored cars are quite often quite beautiful, and perhaps in better condition than when they left the factory. But along with the loss of patina is the loss of lots of original material. Preserved cars retain more history. It appears that just this year Pebble Beach Concours D’ Elegance has added a post-war preservation class. Perhaps this sort of recognition will allow more cars of this vintage to retain their patina.

  • – Interactive Google map thumbnails lard up a blog page.
  • – Named links on static pages work in Wordpress. [(a href="staticpageurl.html#foo")go to foo!(/a) navigates to (a name="foo") on the static page]
  • – Still sorting out how to build a track map/ref/notes structure. I want to quickly jump to high level track information, and then be able to dive deeper into telemetry, video, notes, etc. If I start to race, some of the good shit might have to be password protected.
  • update: lists don’t have bullets in K2. (WTFBBQ?!) Should be an easy CSS fix.

Next Event

Later this month I’ll be running Buttonwillow, Configuration 1, clockwise.

Buttonwillow, Configuration 1

Coastal Driving School has a turn-by-turn guide (pdf).

Trackpedia has a page that’s kinda sparse, but has some useful stuff (including a link to the above guide).

And how about a google map?

Another RFR Video

M3 V8 at RFR

I haven’t done an exhaustive analysis of the line, but I couldn’t ignore a hugely obvious mistake. I find his line through 23 to be absolutely sucktacular. He gives up half a car width, or more, at turn in, and completely ignores a twenty foot apron at the exit. Given that this is a high speed corner dumping onto a very long straight, he’s paying a huge penalty in lap time for this awful line.

The driver works for Motor Trend, so I don’t feel guilty providing an unsolicited, yet harsh critique.

The Racing Geek

Someone on motorsportreg pointed me to a video of a lap of RFR (configuration A). Following the links, I came across a blog that’s been added to my side links, The Racing Geek. The picture below shows his “camera mount”. I doubt this would pass muster with the SCCA, but it’s pretty clever. You need a Lotus Elise or similar for this to work.

Blue masking tape (with a hole for the lens) holds a still camera (with CIF video capabilities) to the rear window.

That’s it.

Angle Brackets

I knew I wouldn’t be able to go for very long without dealing with/talking about the blog tool.

Reno Fernley — New Things

I attended the driving school held by the Sierra Chapter of the BMW CCA at Reno-Fernley Raceway on June 27 -29. The chapter is relatively new — this is their second major event. The track is relatively new — it’s come into being over the last few years. I’m rather “new” to driving, having taken a 5+ year hiatus. The first day on track at RFR was my fifth day on track since getting back to the sport this past fall. The car is relatively new (to me) — prior to the event I had one day on track with this particular car. Although I put over 100k miles on an E36, this beast is an entirely different machine.

Day One, Firday June 27, was two distinct events. For instructors and a select group of advanced students there was a track orientation, Nurgburgring-style. They learned the track in sections, including getting out and walking the track. (I recall back in the day doing some schools that provided a track walk before the speed portion of the event started. I found it very valuable.) The other event was a car control clinic.

I’d signed up for the car control clinic (CCC) because I felt a need to push the limit of this car in second gear in a slalom/skid-pad sort of environment. It’s safer to push it really hard under those circumstances, than to get past the limit in third, forth, or fifth on track. I was mightily tempted to switch to the orientation class, but I stuck with my plan.

I’ve instructed CCC’s in the past, and twice recently. So I was kinda ahead of where most of the class was. We spent a good hour or so working on “this is how ABS works”. That’s a great exercise, but I was getting kinda bored. In retrospect, I should have told the guys, “Hey, I know ABS, how about I work on threshold braking?” The second part of the exercise was the high speed lane change. At 40 mph, this was also kinda boring. At 60 mph it started to get interesting. But then again, I’ve got R compound 255’s, with a coil-over suspension, and all kinds of negative camber.

Next up was the slalom. Like the braking/lane-change exercise, this was held on a section of track in the infield. (The track school was held using configuration B.) The braking exercise was on the mid-straight, while the slalom was on turn 17. This gave us a bit of a bend and a crest to liven things up. I did manage to drive hard enough to get the car loose during this, and missed the end gate during one of my runs.

Then things really got interesting. In lieu of a skid-pad, we used the triangle formed by the mid straight, turn 23b and turn 6b — also known and the wankel, as a little practice course. Each of the three turns is very different. Run in the opposite direction they’re very different again. So we had six little hair-pin corners to play with. In the clock-wise direction I managed to get some throttle-on oversteer coming from the mid straight to 6b. I feathered back a bit and counter-steered to let the rear tuck back in. The next time around I tried to solve it all with counter steer, and kept my foot in it. Can you say “yee haw”? Tail out to the left, tail out to the right, tail out to the left again, tail comes around to the right one more time, and SPIN!

That’s what I needed out of this CCC. For my purposes, I had a very good feel of how the car felt inside the performance envelope. I needed to get outside — not just with push, but with oversteer. What I needed was a car out-of-control clinic, and with both the slalom and the wankel I got it. Win!

That’s enough for now. I’ll return to write about the track school next.

Hey, it’s a blog!

Just what the world needs, another blog.

As the url suggests, this is a blog about motorsports — motorsports in cars with fenders and roofs.
