ST. LOUIS, MO — A season ago, Pro Stock superstar Erica Enders was putting a stranglehold on her second straight Mello Yello world championship with a runner-up finish at the annual AAA Insurance NHRA Midwest Nationals, which takes place again this weekend at Gateway Motorsports Park. It was her fourth consecutive final-round showing and ninth of 11 she would amass during the year.

This year it’s a different story. Enders once again is part of the Countdown to the Championship, but this time she’s 10th in the 10-car field and coming off her first DNQ in six years.

“Same engine builders, same crew, same owner, just different results,” Enders said. “It’s been frustrating but at the same time we’ve learned a lot about ourselves as a group. The last few years we always said, ‘Teamwork makes the dream work,’ and it was so appropriate for the way things were going at the time.

“This year, as it’s gone along and we haven’t found the success we were expecting, our little saying has turned into, ‘No quit in this pit,’ and once again it’s absolutely true. You find out what people are really made of when things aren’t perfect. When you’re winning, it’s easy to jump on board. This year, character has been revealed, and this team of guys has more than any group I’ve ever come across.”

A switch to a new manufacturer has hampered Enders and her Elite Motorsports/Mopar race team to a certain extent, and when you add in the biggest rule changes since the class’ inception more than three decades ago — most notably switching to electronic fuel injection — the group has struggled to find a new groove.

“Just like there’s no quit in this pit, there are no excuses either,” Enders said. “Other teams have figured out the fuel injection better than we have, so it can be done. We’ll get there ourselves; it’s just taking longer than we thought.

“Most of the guys on the team, aside from really important family stuff, haven’t taken a day off this whole year. No one is happy with our performance but no one has complained or quit the team to go somewhere else. I think I’m more proud of these guys this year than I have been the two years we won the championships. That’s saying a lot.”
