Four months ago, Michel Jourdain Jr. was turning laps in excess of 210 miles per hour at Las Vegas Motor Speedway. Wednesday, during a test session at LVMS, Jourdain was about 50 miles per hour slower, but things were no less challenging.

            The nine-year veteran of the Champ Car World Series, who finished 11th in the Bridgestone 400 at LVMS in September, is trying to make the adjustment from the light, quick Champ Cars to the heavier and slower cars of the NASCAR Busch Series.

            ¿This is a whole new experience,¿ Jourdain said. ¿The only thing that is similar is that you go left all the time. When we ran the Champ Cars here, you would just run wide-open all the time. Here, I have to brake. I feel like a first-timer. Everything is so different. The cars are so heavy, there's no downforce.

            ¿I feel like a first timer. It¿s like (a NASCAR driver) coming here in a Champ Car.  It would be completely different.¿

            Jourdain, who is teaming with Kenny Wallace at ppc Racing, is leaning on his veteran teammate as well as spotter and former driver Andy Houston for help.

            ¿They have been great with me,¿ Jourdain said. ¿There is so much more to learn. Just the difference from sitting in the middle of the car to sitting on the left side of the car is an adjustment.¿

            Jourdain was one of 22 NASCAR Busch Series drivers taking part in Wednesday¿s session of NASCAR Preseason Thunder Las Vegas. The drivers will conclude their testing on Thursday as they prepare for the March 12 Sam¿s Town 300.

            The only incident of the day occurred during the morning session. David Reutimann, who was subbing for Joe Nemechek, blew an engine in turn 3. Carl Edwards and Johnny Sauter hit the oil and spun. Edwards¿ car made significant contact with the outside wall. Edwards tested his backup car for the remainder of the day.
