Grumpy Cat Dodge Challenger Hellcat Runs a 7.07 Quarter Mile

For the past few years, the Dodge Challenger SRT Hellcat campaigned by the Epling Family race team has held the record for the world’s quickest and fastest Hellcat car in the quarter mile. Most recently, the Epling “007” Challenger ran a stunning 7.33 at 186 miles per hour to once again reset their own world record, but on Monday, September 13th, a somewhat new name climbed to the top of the list of the world’s quickest Hellcat cars…and that name is Grumpy Cat.

Grumpy Cat is the name given to the Dodge Challenger SRT Hellcat of Kevin Helmick and over the past year or so, he has been working hard to dial-in this heavily modified Mopar muscle car. We say that this car is “somewhat new”, because Helmick first raced this car in production form before transforming it into the beast shown here and since the race-ready transformation, Helmick has been close to the Epling record, even claiming the record only to have the Eplings take their record back later that day. However, all of the work and dedication that went into this Challenger paid off yesterday afternoon when Helmick laid down the quickest quarter mile elapsed time by any vehicle to come from the factory with a Hellcat Hemi by a substantial margin.

While racing at Virginia Motorsports Park, Helmick and the Grumpy Cat Dodge Challenger ran a mind-blowing 7.07 at 184.98 miles per hour, making this the quickest Hellcat car in the world. Of course, with this Challenger coming from the factory with 707 horsepower, it is particularly fitting that Helmick would claim the record with an E.T. of 7.07.

You can watch that record-setting run in the video at the bottom of this piece, but first, let’s take a look at what went into putting this Dodge Challenger into the 7.0 quarter mile range.

The Grumpy Cat Challenger Hellcat

As you can surely tell from the images here, this Dodge Challenger SRT Hellcat is very different from the way that it came from the factory. In fact, just about everything has been changed, but when you are looking to get a muscle car that originally had 707 horsepower and a curb weight of more than two tons in the low-7-second range, you are obviously going to have to make lots of changes. That being said, this car began its life as a run-of-the-mill Dodge Challenger, but today, it is a race-ready record-holder.

In short, this Dodge Challenger SRT Hellcat has been fitted with the best of everything, from chassis and interior components to engine and transmission parts. Helmick spent many hours behind the wheel, getting a feel for this beast and on Monday afternoon, it all came together in what would become a legendary, record-setting quarter mile pass.

The New Hellcat Record

In the video below, you can watch as Kevin Helmick pilots the Grumpy Cat Dodge Challenger SRT Hellcat race car down the quarter mile strip of VMP. The first bit of track footage shows the record run, with Helmick running the 7.07 at 184.98 miles per hour. On that run, the Grumpy Cat Challenger pulled an incredible 1.155 60-foot time, getting to the 8th mile marker in just 4.589 seconds and with a speed of 162.7 miles per hour. Of course, on the big end, he stopped the timers with the remarkable 7.07 E.T.
