Dodge Challenger 1320 Runs an 11.48 with Minimal Upgrades
Challenger 1320 has aftermarket wheels, tires and a lightweight battery, running on stock power.
The Dodge Challenger R/T Scat Pack 1320 is the quickest factory-built, naturally aspirated road car ever, carrying an official quarter mile time of 11.70 from FCA. That number was set using the factory-issued Nexen drag radials, but Tim Holmberg of Holmberg Motorsports found that with better drag radials, lighter front wheels and a lighter battery, it isn’t hard to outrun Dodge’s official number, even with less-than-ideal air conditions.
This week’s Track Time Tuesday video comes from the YouTube channel of Patrick Rall and it features Holmberg’s Challenger 1320 running an 11.48 in the quarter mile, comfortably eclipsing the Dodge number with a few simple changes.
Holmberg Motorsports Challenger 1320
When the Dodge Challenger R/T Scat Pack 1320 comes from the factory, it rides on unique 20-inch wheels wrapped in Nexen drag radials at all four corners. With help from the drag mode suspension settings and the 485-horsepower Hemi, Dodge was able to get the 1320 into the 11.70 range during testing, which is quicker in the quarter mile than any other naturally aspirated car sold in the United States.
However, while the Challenger 1320 comes with drag radials, the Nexen rubber isn’t as good as some of the bigger-named drag radials on the market, so Tim Holmberg removed the factory 20-inch wheels and replaced them with a set of 18-inch rear wheels wrapped in a set of 305/45/17 Mickey Thompson ET Street R tires. These are arguably the best drag radial on the market today, helping many modern Mopar owners and drivers turn their best times.
Next, the 20-inch front wheels were replaced with 18-inch “skinnies” that weigh far less than the stock wheels and tires, while the weight reduction effort was continued with a lightweight battery. Everything else in this Challenger 1320 is stock, right down to the single-seat interior configuration.
1320 Hits 11.48
In the video above, Holmberg is piloting the B5 Blue Challenger 1320 down the quarter mile track of Brainerd International Raceway in Minnesota. The density altitude was around 2,100 feet on this pass, so this is not a “unicorn run” made at hundreds of feet below sea level. Mind you, those runs with incredible density altitude certainly count, but by pointing out the DA here, we are making the point that to run in the 11.40s with a 1320, you don’t need extreme conditions.
After a quick burnout, the Challenger 1320 eases into the beams and waits for the green lights to drop. When they do, the Mopar muscle car comes storming off of the line, beating the classic car in the far lane to the finish line and running an 11.48 at 118.38 miles per hour.
It should be noted that Holmberg has run an 11.48 with this Challenger 1320 on two separate occasions, so this was not a fluke, showing that with very minor changes, the 11.70 official time can easily be beaten.
