Hellion 2018-2023 RHD Ford Mustang GT Street Sleeper Hidden Twin Turbo System
Years ago, we recognised the popularity of high-horsepower cars with the ultimate “sleeper” image. Hellion designed the most innovative twin-turbo system in history — the Street Sleeper. We have listened to our customers who desired a different design for the S550 Mustangs. This new system places the turbos in a hidden location. It is a twin-turbo system that is fully adjustable from 5 to 40 pounds of boost, and performance levels anywhere from 600 to over 2,000 horsepower!
This is the most powerful system available for the Mustang, period. No supercharger can even come close to the potential of a Hellion Twin Turbo. One of our most common conversations with our customers is “I’m pulling off my supercharger and purchasing a Hellion kit. I can’t keep up with other Hellion cars.” You just can’t beat the power of a twin-turbo Mustang.
With over 20 years of experience in turbo system design, Hellion has developed a proper bolt-on system for the S550. There is no need to tap the oil pan or modify any factory sheet metal. The simple installation can typically be completed in under a day.
While the base Street Sleeper system is a tuner kit with entry-level 62mm turbos, Hellion naturally offers a wide range of upgrades, including a choice of turbo sizes, fuel system upgrades, and even complete blackout packages.
The benefits of a twin turbo system go beyond the incredible looks and sounds of a pair of turbos–no other power adder can deliver the crushing power and torque a Hellion twin kit can. While superchargers constantly drag the engine down with parasitic losses via a belt, a turbo setup utilises the energy in spent exhaust to generate boost, with no extra losses. This equals more power to the tyres and faster times!
