Thunderhill 2010/05/18 (GGLC)


Fun track day with Lotus Club.  I'm feeling more comfortable pushing the car but there's still lots of room to go faster.  A few pics from the day:

2 quick laps (both in the 2:06s, would be a 2:05.x if best of both were combined) - click twice for hi-def:

- Played with suspension a bunch - details coming; upshot was the car felt best with 4/4/2 front and 3/3/2 rear
- reduced wing angle 1 turn on right and 1.5 turns on left
- right rear wheel has excessive camber and it showed in the handling - left turns exhibited more understeer than rights
- I'm still learning the turn-in speed this car can handle - much higher than the Evo
- power felt great; the new header (jethot coated Toda) and tune were spot on - thanks Shad @ http://www.drivingambition.us

  - car gained 10 or peak whp and 15wtq through the midrange!

More notes:
At the Golden Gate Lotus Club track outing at Thunderhill the next day, I got through 6 20min sessions with only 17 gals of 92.8 octane (20% 100 and 80% 91).  The Evo easily used more than 2x as much.  I also discovered that I can run the fuel cell down to an indicated 0gal on track without starvation.  Granted I still need to calibrate the sensor...

I still have a ways to go but I started to feel better pushing the car.  My best time was a 2:06.27 (over the top).  I haven't checked the GPS data yet but I'm certain there's a theoretical best in low 2:05s.  Next time I expect to be in the 2:04s or better.  For more pics of the changes made to the car before this day, see the build and maintenance section.
