TURBOCHARGED CAPABILITY

The TurboMax™ engine delivers the capability you demand when you need it most by providing next-level performance and low-end torque.

Combustion Process

The TurboMax™ engine offers powerful diesel-like performance while running on regular fuel. A multi-hole direct injection with up to 2,900 psi of pressure helps maintain high efficiency.

Turbo Design & Integration

An inline 4-cylinder arrangement provides a symmetrical natural turbo placement. Large cylinders feed into a near-equal-length integrated exhaust manifold that couples with the dual volute turbo. That means you get exceptional responsiveness and turbo boost performance.

Air Compression & Cooling

A large-charge air cooler acts as the middleman between the turbo and engine. This feature takes warm, compressed air and cools it down before reaching the engine, increasing efficiency and power. The result: optimum towing capability in hot conditions.

A Summary of Performance

This is a unique engine. And what makes it so appealing is its remarkable capability, torque, and improved fuel efficiency. The details you’ve seen so far, combined with advanced controls, give the TurboMax™ engine its high power output and 430 lb.-ft. of torque. It’s a product of rigorous testing and real-world trial that’s ready to work for you.

Fully Forged Bottom End

Heavy-duty durability starts with a strong foundation. The engine has a fully forged-steel bottom end, starting with a stiff forged-steel crankshaft and supported by forged-steel main bearing caps.

Diesel Engine Technology

The TurboMax™ engine is designed to take on heavy loads with turbocharged power. That’s why it’s equipped with diesel technologies, such as tri-metal rod bearings, pistons with a fully machined crown, and a cast-iron ring carrier supporting a physical vapor deposition (PVD) coated steel top ring.

Design & Build

The hydraulic tensioners reduce chain drive stress and high loads on chain drive systems to provide the durability you’d expect. The lower crankshaft extension helps support the main bearing caps, giving the engine a strong foundation to handle heavy turbocharging loads.

Thermal Conductivity

Cast-iron liners provide a durable wear surface for the rings, which is critical for long engine life. A locking interface helps move heat out of the cylinder to the water jacket where cooling occurs. Sodium-filled exhaust valve stems and high thermal conductivity valve seats and guides help keep exhaust valves running cool in extreme, high-performance situations.

Turbocharger Lubrication & Cooling

Symmetrical natural turbo placement allows for priority feed oil from the filter and the perfect coolant routing. This provides thermosyphon cooling, which aids in keeping the turbo cool after shutting down. And under extreme conditions, the electric water pump can provide after-run cooling. Keeping the turbo lubricated and cool are the keys to a long life.
