Day Four - Thunderhill Raceway - Counter Clockwise (Willows, CA)

"Give me a Brake"

Another track, another 7:30am arrival to setup and have time for the driver's meeting.  Our trailer tire was flat again in the morning so we went by the Arco to fill it up.  On the way around the back of the building, I managed to cut it a little to close and clip a pole with the trailer fender.  I took out one of the marker lights and bent the fender a bit.  Not too bad, but it's not my trailer.  Looks like I've now got four incidents to Dave's one.

Neither Dave or I have ever been to Thunderhill before and from the looks of the track, it's going to be very interesting.  Thunderhill has endless elevation changes, blind corners, and roller coaster hills.  Dave decides to ride with me for the first session to learn the lay of the land.  I felt intimidated just looking at the track and that feeling got even worse once we were out there.  I've never been a natural at learning a new track and picking up the lines.  It usually takes me a while to get comfortable and up to speed.  This made learning Thunderhill even harder.  The track has very limited lines of sight and it's very long (three miles) meaning less laps per session.  Needless to say, I did terrible and was more than 30 seconds off the pace.  Clearly, I had a lot of work to do.  Dave did much better than I did in his first session but we were still pretty far back overall.

After lunch I decided that it just wasn't going to happen for me today so I let Dave take both afternoon sessions to see if he could bring his lap times down.  We walked over to the track office after we ate and found that our used starter had been delivered.  It took just fifteen minutes to remove the old, hollowed out unit and install the new one.  We turned the power on, crossed our fingers and pressed the button.  We were rewarded with the wonderful sound of our Kawasaki engine firing up with any pushing!  We yelled loud enough that people at the other end of the paddock knew we had our starter back.  Before Dave went back on track, we also jacked up the trailer and pulled off the flat tire.

Dave took full advantage of his two afternoon sessions to reduce his lap time to 2:12.445.  He also went four wheels off (but kept going) so now the incident count is four to two.  If Dave keeps this up, we might even out by day seven!  Unfortunately, Dave's time weren't enough to keep us from slipping a few more notches down the list for overall points.

After the last session, Dave was complaining about the brakes feeling weak.  We took a close look and discovered why.  Cars like ours are usually setup for oval racing and left foot braking only (since the steering column blocks access to the pedal with the right foot).  For our road racing version, the factory installed a pedal extension which allows braking with either foot (and heel to toe downshifts).  While the idea sounds great, in execution, it was far from perfect.  To start, the support for the pedal extension bottomed out on the steering column heim joint support and then the chassis.  This prevented full braking force with the right foot.  With our current bias, we measured 300 PSI of braking force with the right foot.  Without changing the pedals, pressing the brake with the left foot yielded an increase to 600 PSI (double!).  Obviously, we had a serious problem here.  We removed the pedal extension and started working on a solution.  With the extension removed, strong left foot braking got us 1200 PSI of front braking force, a 400% improvement over what we saw at first!  We starting playing with the pedal and after some gentle adjustments to the support arm (okay, we used a sledge hammer), we put it back on the car for a test.  The new setup netted 600 PSI of front braking force with the right foot at 900 PSI with the left.  This was a huge improvement and the best we could do at the time so we put everything back together and called it a night.

We're staying overnight and running clockwise tomorrow, which should be even more interesting.  At least we get one night to relax a little.  Ron Wasserman put together a dinner at a local Italian restaurant but Dave and Maria were pretty tired so we skipped it and had a quick meal at Round Table Pizza instead.  We also stopped by a gas station and had the tire patched (it seems we picked up a big wood screw somewhere).  Believe it or not, there is a Wall Mart in Willows (population 6000) so we went in for supplies.  We picked up a replacement light for the trailer and a radio ear bud so we could try and use our FRS radios in the car.  It was nice to get back in the room, take a shower and be in bed by 10:00pm.
