Demon Runs 10.30s on First Real-World Track Rips with Race Gas

Now that customers are getting their hands on the 100-octane tune, the track times are speaking volumes.
Today we bring you what we believe to be the first look at a privately-owned 2018 Dodge Challenger SRT Demon making a quarter mile run with the race gas PCM. This is the owner’s first trip to the track with the newly-installed 100-octane race gas PCM from the Demon Crate, while also being his first time down a quarter-mile track with the supercharged Mopar monster. He has made some roll-runs on an airstrip with the stock PCM, but this is his first time at the track with all 840 horsepower.
The Man Behind the Demon
Before getting into the detail of this run, here are some notes on the car and the driver. This bright-yellow Demon is owned by Craig Belevender, who received his supercharged Challenger a few weeks back. After a couple of weeks, he received his Demon Crate, so he headed to the dealership to have the race gas PCM installed (thus protecting his factory warranty).
Once he had unlocked the full 840-horsepower potential of his 2018 Challenger Demon, Belevender headed to Wild Horse Pass Motorsports Park. His goal was to get a feel for the unique TransBrake launch control system and over the course of the evening, he made six passes down the quarter-mile dragstrip. The car has the wide front wheels/tires and the full interior, along with the race gas PCM and a tank full of 100-octane fuel.
Learning the TransBrake
When we tested the Demon last summer, we were happy to run a 10.50 with the TransBrake system with only a handful of runs. The TransBrake is a unique tool, and while it unlocks the Demon’s ability to run in the 9s, it takes some practice to get the hang of this high-tech launch system. This is not a car that everyone is going to get in, mash the pedal, and run 9s, but based on Belevender’s first trip to the track with all 840 horsepower, 9s aren’t far away.
Belevender made six runs and his best pass of the evening was a 10.378 at 134.7 miles per hour. On that run, he had a 1.625 short time and eighth mile figures of 6.721 at 106.86. Critics will point out that this is about seven tenths of a second off of the 9.65 record for the Demon, but there are a few things to keep in mind here.
Breaking Down the Runs
First, the Demon’s record runs were made in the best possible conditions possible, running in southern Florida at night in late November. Density Altitude (DA) during the 9.65 run was well below 0. During Belevender’s 10.378, the DA was around 1,500 feet, so there was a huge difference in air quality.
Second, when the Dodge team got their test Demon into the 9.60s, the driver had made hundreds upon hundreds of runs down the track. Craig Belevender has made six runs, so with the Demon being a car that requires some seat time in order to run the best numbers, he has a few hundred runs worth of practice to catch up to the Dodge test team.
We will continue to monitor Craig Belevender’s Demon as he gets more seat time, but for now, he is running in the low 10s.
