The day started with a torrential downpour.

The classroom just before 8AM. We were still asleep.

Shawn showed off his new mods- including Brospeed headers installed just the day before. Read about his install on the Headers Page.

To the right you can see the lines of cones marking off the J-Turn exercise. You accelerate to speed, then the course turns to the right (too far to see in the pic) and you slam on the brakes at a certain marker and feel how the ABS allows you to turn and come to a stop. I've played around with ABS alot, but the instructor taught me a few new things!

Then we got to drive the LT1 (Corvette engine) powered police cruisers on the skid pan. The skid pan is concrete flooded with 1/4 inch of water. We would take it into the corner, then apply throttle to break the rear end loose, then modulate throttle and steering to save the car. i spun out the first three times! The engines are so powerful and the surface so slippery it didn't take much to get into an uncontrollable spin. With a little help from the instructor, I discovered that applying instant counter lock (steering into the slid) was highly effective. The sooner you applied opposite lock, the less the back end would slid out. If the slip angle at the rear exceeded about 25 degrees, nothing will stop the spin. .
We had another short classroom discussion, then out to run the pursuit course. The Pursuit course is used to train officers in high speed vehicle chases. The course could be set up in several different ways- like an autocross course, or with two legs joining different parts of the course. The two legs allow the chance to try to chase another car- unlike a race track you are having to make decisions about entry lines without knowing which way you will be going in advance.

Chasing the Police!

We could decide whether to drive the course alone or try to chase one of the police instructors in a pursuit cruiser. At first the coordinator bragged that they would lap people in a 1 1/2 laps. When they first set up the course one of the best drivers demo'd the course, flinging the huge cruiser around at a terrifying pace- perfect power oversteer through the tight corners, burning up rubber and turning massive car around in the width of an alley by sliding and pivoting around the center, all the while a cigarette dangling at a jaunty angle. We were a little intimidated, but Mike whispered to me that these guys might be surprised what a Probe could do on a course like this.

It was a strange sight- the gigantic cop car hurtling around the track in a cloud of rubber and brake dust, sliding gracefully through corners and looking like it was going 100 mph. And right behind the PGT, loafing along effortlessly. I had to keep stopping and let the guy get a good head start because I would catch up so quickly. This happened a few times and I heard one of the instructors say they needed the keys to the Taurus pursuit vehicle. Don't know what they had in that.

Of course the track was still wet at the time, giving the FWD PGT a huge advantage.

Performance Driving

Then it was my turn to drive with the EVOC instructor in the car. I come barreling out of the turn before a slalom like straight and nail the throttle. As we whip around the middle curve I hear a slightly panicked voice from the passenger seat saying "too fast!, too fast!!", but being familiar with my car I keep the right foot buried and thread through the twisty bit at the end, finally hitting brakes- then the instructor with surprise: "boy, these cars sure handle better than I thought!". Every person that came back from that session said the instructors were amazed at the handling of these FWD cars.

My first session out alone got the attention of everyone, as high on adrenaline I proceeded to make every mistake I could, rolling over my tires and making a huge racket. Yes, the 16-year old in me still lives! Mike took pity on me and rode with a few times, and I rode with him. That helped me a lot- and not in small part due to his calm, efficient style while driving.

There were more sessions until the end of the day with various pursuit configurations. Everybody drove well and the improvement was obvious. The EVOC instructors did a great job and were very friendly and patient.

If we weren't on the real course outside, we got to use the state of the art driver simulator where four people could drive together on an autocross/street type course.

Mike gives Ian a few pointers on driving his new 1999 Miata- got to be pretty careful not to spin in that thing.

Here are our six instructors.
Terry, EVOC coordinator (white shirt)
Bill, retired sergeant, CHP
Tom, retired lieutenant, CHP
Fred, retired agent, FBI, NASCAR driver
Curt, retired CHP
Joe, retired EBRP
Mike got some of them interested in racing autocross. I think with the right car they would do pretty well!
