Features, Description, Q&A, Specs & Installation
Top Mount Turbo System. The On3 Performance Top Mount Twin Turbo System with GT30 55mm Cast Wheel Ceramic Ball Bearing Turbos is engineered to significantly enhance the power output of the 2015-2017 Mustang GT 5.0. This system replaces the factory setup with a twin turbo arrangement that boosts horsepower and torque while maintaining excellent drivability and throttle response. It is ideal for enthusiasts seeking both street performance and high horsepower potential with a reliable and tunable platform.
Construction and Appearance. The system features forward-facing cast stainless steel manifolds designed for optimal flow and visual appeal. High-quality 304 stainless steel is used extensively for headers and downpipe components, while the cold side employs polished 6061 aluminum tubing. V-band inlet and outlet housings ensure smooth round-to-round transitions, reducing turbulence and increasing efficiency. The intercooler is a 3.5" bar and plate design, capable of supporting up to 1200 horsepower, complemented by high-quality silicone couplers and T-bolt clamps for secure connections.
Installation. Installation requires moderate mechanical skill but does not necessitate drilling or major fabrication thanks to the included ECU and fuse panel relocation kits. The system is designed for ease of install with V-band clamps and preassembled components simplifying the process.
Application. This twin turbo kit fits the 2015-2017 Mustang GT 5.0 exclusively, with no fitment for other generations or models. It is designed specifically for the S550 chassis with the Coyote 5.0 V8 engine configuration.
