“Hellcat The World!” – Custom Dodge Charger SRT Hellcat:

Charger SRT8 Gets Total Makeover...

When the Dodge Charger SRT8 made its debut in 2006, the four-door muscle sedan shooked up the automotive world with its 6.1-liter SRT HEMI V8 pumping out a then staller 425 horsepower and 420 lb.-ft of torque. The Charger SRT8 had a 0-60 mph in the low 5-second range with a quarter-mile in the mid-13-second range. Fast forward thirteen years and while the current Charger is still on the same architecture, a lot has changed.

Today, the top of the line SRT-based Charger features a 707 horsepower and 650 lb.-ft. of torque supercharged 6.2-liter HEMI V8 and can run a 0-60 mph in the low 3-second range while running a quarter-mile in 11-seconds flat. 

So what happens when you take a 2007 Dodge Charger SRT8, ditch the 6.1-liter HEMI V8 and stuff in a supercharged HEMI Hellcat V8? You get the HellX, a creation from Jim Koutsoubis of True Steet Performance in Bay Shore, New York. 

Our own R/T Life had a chance to check out this monster Charger recently. The car isn’t just a powertrain swap either. Thanks to an upgraded pulley the car produced 705 horsepower to the rear wheels. A Paramount NAG1 transmission and a 3.09 rear axle ratio propelled the car to a 10.2-second quarter-mile time. 

True Street Performance also grabbed some other goodies from the modern-day Hellcat. The HellX is also equipped with the Charger SRT Hellcat’s 15.4-inch Brembo two-piece rotors and six-piston Brembo calipers up front and four-piston Brembo calipers in the rear. Hellcat sourced “Slingshot” seven-spoke wheels, Hellcat-style hood, and a full Hellcat exhaust. The HellX also tastefully features OEM Hellcat badges on the fenders, no off the wall graphics here. Inside, the HellX features a set of leather and suede Hellcat bucket seats.

Special thanks to Jim at True Street Performance and our friend R/T Life for giving us a look at this radical 2007 Dodge Charger. Be sure to check out the R/T Life YouTube channel for some other amazing Mopars he has been scoping out lately. Stay tuned as continue to share some of the amazing custom Hellcat-powered rides.
