This built and blown Dodge Challenger R/T runs a 10.78 and sounds awesome while doing so.
The Dodge Challenger R/T is a great modern muscle car, parking 375 horsepower and the ability to scoot down the quarter mile in the 13-second range in stock form. The Challenger R/T in the video above from the YouTube account of zilluka looks similar to how it came from the factory, but under the skin of this classically-designed Mopar muscle car is a monster blown Hemi.
Stroked and Blown
This Dodge Challenger R/T is owned, built and raced by JR Sehmbi and it is powered by the 5.7L Hemi, stroked to 392 cubic inches. That big-cube Hemi is topped by a set of Eagle cylinder heads and a ProCharger F1A supercharger. That supercharged power is sent to the beefy rear race tires by means of a 6-speed manual transmission, so JR is launching on the clutch and banging gears, yet he is still getting his Challenger R/T down the quarter mile in under 11 seconds.
To be exact, on this run, Sehmbi’s Challenger R/T stopped the timers with a 10.78 at 138 miles per hour. On this run, the tires spun a little on the launch as the Dodge muscle car ripped away from the starting line, but it was still able to get down the track well into the 10-second range.
When watching the video of JR Sehmbi’s blown Challenger R/T blasting down the quarter mile, make sure to have your volume up, as this car sounds absolutely amazing. The video begins with a quick rev of the engine, which is sure to get your attention, and it sounds even better during the burnout. However, the sweetest sound comes when the car launches at high RPM and rockets down the track.
Twin Turbo Conversion
In speaking with JR Sehmbi, he explained that this ProCharged 392 was his old setup. The car is now fitted with a twin turbo setup and it is “much faster”. With any luck, we will get videos of the car with the new setup in the near future, but in the meantime, crank up your speakers and enjoy this 10.78 run.
"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.
"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.
"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.
"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.
"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.
