Eric Jones - 2008 Shelby GT500

If Eric Jones’ Fatal 500 looks familiar, it’s because the car appeared on these page before in our Showcase section. Its prior owner got in hot water street racing and had to trade it in. That owner’s loss was Eric’s gain, and though the car already had some mods in place he kept that them going by adding more. Even while doing all that, he never kept the car off the road. He simply loves driving it daily, racking up over 72,000 miles. He says he loves to surprise Vettes on the street.

At our Battle, Eric drew the second to last slot in the running order, so he too was running in the mid-day heat. Adding to the challenge, he had recently added a nitrous kit to the combination and it wasn’t playing nicely with the drivetrain.

“I added the NX Nitrous kit the week before in hopes of reaching 700 rear-wheel horsepower. Dan at Pro Dyno tuned the car and found the clutch was slipping after 4,500 rpm; it was flat-lining after that. This is all with a stock GT500 clutch,” Eric explained. “So, I knew going into the event it was only going to make around 675 to 685. It makes 623 without the NX kit and I ran a 100 shot. I’m losing some horsepower through the clutch.”

In the end, he still showed well, especially for a stock-blower car, landing in the sixth spot with over 684 hp at the wheels.

Rick Marion - 2013 Shelby GT500

It’s a testament to the modern Shelbys that they can run with heavily modded ’Stangs from the past. They really are the most impressive ’Stangs built to date. A prime example is Rick Marion’s ’13 GT500. His car features some of the typical exhaust, pulley, tuning mods you would expect. What is unusual about Rick’s car is its post-title mods.

“This is hands-down the most powerful and quickest car I have owned. It is a pleasure to drive around town, to car shows, and it never sees a trailer,” he said. “This is the first car I have ever ordered to my specifications, and I couldn’t be happier with what Ford offered and produced. The modifications Fastlane performed made my dream car a reality.”

It turns out picking up the tach signal on these cars is tricky, so Rick’s car dropped the torque reading on its first run, but its second run produced higher power anyway. His bolt-on Trinity put down over 666 rwhp to take seventh place in the Battle.
