2011 SASCA Event #4
Blossom Athletic Center
April 17, 2011
Course Designer: Chris Leclair
Fastest Time of the Day: 36.582 seconds
Fastest Street Tire of the Day: 37.333 seconds

This was my first course design ever and definitely not my last one.  Please feel free to leave your comments about how the course drove for your car

1. Tuck In:
You start off making a right hand turn down and into a left hand sweeper.  It was very easy to get a good launch and carry speed down through here but if you didn't lift just slightly to tuck the front tires in for the start of the slalom you would push wide and wash out.  They key to set up for the slalom here was to lift just slightly just before the second gate to set the front tires and continue on.

2. Looking Ahead:
After the 3 cone slalom there were 2 pointer cones making the left hand arc before entering the wallum gate.  Keep a constant speed around this arc and start accelerating before entering the gate to set your speed for the wallums going up hill.

3. Wallums:
Not seen nearly enough at local events but I can pretty much guarantee that you would see one at the major out of town events.  We normally run this section of the lot going down hill but since we were going uphill I wanted to not give the high horsepower cars too much of an advantage so I added the wallums; I don't think that worked out quite as planned from what I heard, hehe.  The first three wallums were spaced evenly and the last one was made just slightly tighter to slow down the exit speed near the poles at the top.

4. Managing the dips:
When setting up the course in the morning I had to change my plans here due to the 3 dips in the middle of the lot.  After the last wallum there was a long wide left arc down back towards the building transitioning into a slow speed right hand turn around to go back up the hill.  You could either cut the cones saving distance or swing wide on the first and cut in on the second to accelerate up the hill.

5. Chicane:
This was an interesting chicane between the two Chicago boxes.  You had to look ahead and plan your entry/exit through the first Chicago box in order to align your car correctly on the left side of the chicane so you could be full throttle through this transition.  A lot of people carried speed through the first Chicago box and were way right of the chicane which caused them to slow down, turn left and then right to go through.  Finishing through the second Chicago box was very similar.  People who cut off the pointer cone were left wide to the right of the finish.  If you carried full throttle speed through the chicane it should have left your car on the right side of the Chicago box to cut a wide arc to the finish.

1. Yes!

2. The lefthander before the wallums featured a "slick spot" that would throw my car off line.  I had to be very careful going back to power, especially with 70+ run old tires.

3. These used to be no problem for me, but I think old age is making me timid.  I was WOT until about the second one, then I would brush the brake so I can set up to power through the exit.

4. For some reason, my clouded judgement made me cut the corner and try to save time with a high powered car.

5. Cutting the corner and being wicked slow did allow me to go WOT up the hill, but I didn't carry enough speed around the last cone of the slalom.  The finish was fast and fun as long as you late apexed the last cone before the lights.

Take it as you will, because if my autocrossing continues to "progress" as it has since the last event before the National Tour, by September I'm gonna need an N in front of my number.  And I'll still lose - while running R-comps.
