BONNEVILLE, UTAH — Rob Freyvogel hit another bump in the road in his quest to break a record at Speed Week.

Freyvogel of Butler Township was riding high heading into Wednesday, with his custom-made Carbiliner car excelling at the event at Bonneville’s Salt Flats.

He had just recovered from electrical problems to the car to race it at 363 mph on Tuesday, a record-breaking qualifier in the Double AA/Blown Gas Streamliner class (the record is 348 mph).

However, Freyvogel needed consecutive races to average out his speed to break the record, and on Wednesday, the Carbiliner malfunctioned again.

“Things went pretty bad,” he said. “We had a little suspension malfunction and the car dropped down on its suspension hard.”

This caused the fuel pump to turn off, and the car to lose its fuel pressure, so Freyvogel had to turn off the car and veer off the course.

At the time, he was at 301 mph and around the 3-mile mark.

Freyvogel and his team went right to fixing the problem. It turned out to be body work damage, and not as bad as they had expected.

“I’m still optimistic,” he said. “You have to crack down and go when the going gets tough, and put your nose to the grindstone and fight until the end.”

Freyvogel was set to race again Wednesday night. His results were not available.

The Carbiliner was designed in 2009 and completed in 2011 by Freyvogel and Brandon Barnhart of Harmony. It is 28 feet long, 3,000 pounds and contains a 2,600-hp engine.

Freyvogel is one of about 500 competitors in the 68th annual Speed Week, which is being run through the Southern California Timing Association.

The event began Saturday and runs through Friday.

Racers driving vehicles in the variations of modified cars, streamliners, roadsters, sedans, coupes and motorcycles are spread across hundreds of classes.

With crew members accounted for, there’s a few thousand people in competition, and, according to Speed Week media liaison JoAnn Carlson, “another several thousand” come as spectators throughout the week.

It’s been the first Speed Week since 2013 because of poor weather conditions in 2014 and 2015.

“It’s a reunion this year because it’s been canceled the past two years, so everybody’s very excited,” Carlson said.

This year, Speed Week has three courses: a one-mile rookie course for first-time participants and small motorcycles that don’t run very fast; a short-course, that measures speed for three miles, and a long course, that measures speed for five miles, on which Freyvogel is competing.

So far, Freyvogel has been one of the big hits of Speed Week. Between 150 and 200 media members are on hand for the event, and they are issued press passes with Freyvogel’s custom-made “Carbiliner” on them.

“We did this press pass months ago,” Carlson said. “We said, ‘Oh, let’s use that car,’ because it’s real special.”

While computer glitches have kept the SCTA from posting results online, the event has been broadcast by radio and Carlson said everything else has run smoothly.

“The weather is beautiful and the salt is good, and everybody is having a very good time,” she said.
