MONTEREY, Calif., Oct. 8 - Friday afternoon Jeret Schroeder of Vineland, N.J., posted the 15th-fastest time in the first round of qualifying for Sunday's VISA Sportscar Championships American Le Mans Series race at Laguna Seca Raceway. The starting lineup won't be determined until the final round of qualifying tomorrow (Saturday) from 2:50 p.m. until 3:10 p.m., with each car's best lap over both sessions counting. Schroeder's lap Friday virtually assures that the TRV Motorsport team's Supreme Exhaust System Products/Purity Farms/Racer Parts Wholesale Riley & Scott Chevy #95 will be in the field Sunday, however. The team has been hampered by an intermittent yet persistent electrical engine management firing problem, the same problem that it faced in last month's Petit Le Mans at Road Atlanta. Unfortunately almost all the available time the team had in testing Thursday and practice Friday was spent trying to solve this problem. "The engine management system problem is causing a hesitation in the engine which has adversely affected our performance," said team owner and co-driver Tom Volk of Blissfield, Mich. "Our engine builder, Todd Hertel; three people from MoTec, which supplied our engine management system; and our entire team have been working on trying to solve the problem instead of doing what we all would like to be doing, which is working on our set-up," Volk said. "We put a different set of gears in before qualifying and Jeret said that helped," Volk added. "So far this weekend Jeret has done about 60 laps and I've done about 10. I raced here once before, and Jeret has raced here twice before in Toyota Atlantic events." The team's regular engineer, John Greene, was unable to attend this event. Pep Boys Indy Racing League team owner Dick Simon was going to help out in that department if his schedule permitted, but unfortunately he is not here either. Schroeder and team manager Mike Madden have been handling most of the engineering duties here this weekend so far. The team's qualifying session on Friday was cut short by an alarm that went off which showed that the engine was overheating, but that turned out to be a false alarm. "The car was much better in qualifying than it was in practice, but unfortunately we're having some computer problems and our alarm warning numbers were switched," Schroeder explained. "The alarm went off about five laps into qualifying, so I came in so the crew could check it out. I went back out and it didn't get any better, but the engine really wasn't overheating; the alarm numbers had been changed somehow," he said. "We'll make some more changes to the set-up and see what happens in practice and qualifying tomorrow," he added. Schroeder said the track conditions were "a little sandy" on Friday, but overall he thinks Laguna Seca Raceway is a great facility. "The improvements they've made since the last time I raced here have made the track much safer," he said. "They changed the pit-in and turn 10. They added run-off room and enlarged some of the gravel traps. It's a really nice race track." Sunday's two-hour, 45-minute race is scheduled to get the green flag at noon. It will be televised on CNBC on a same-day, taped-delayed basis from 4 p.m. to 6 p.m. EDT Sunday.
