Turbocharger for Detroit Diesel 8V71 Engines

The turbocharger is the driving force behind the 8V71’s performance. It compresses the air entering the combustion chamber, improving both power and fuel efficiency. The Detroit Diesel 8V71 turbo is a precision-balanced, heavy-duty unit designed for continuous operation in marine conditions.

Key Features:

• Built for marine intercooled applications — corrosion-resistant materials designed for saltwater environments.

• Improved efficiency and power — delivers increased horsepower with smoother throttle response.

• Factory-balanced assembly — reduces vibration, extending bearing and turbine life.

• Direct-fit installation — compatible with standard Detroit Diesel 8V71 turbo configurations.

When properly maintained, a turbocharged 8V71 runs cleaner, burns fuel more efficiently, and maintains stable power even under demanding load conditions.

Turbo Gaskets and Sealing Components

A turbo system’s performance depends heavily on the integrity of its seals. Diesel Pro Power offers a complete line of gaskets for the 8V71 turbo system, designed to withstand extreme temperature fluctuations and pressure.

Turbo Exhaust Inlet Gaskets

High-temperature gaskets that create a tight seal between the turbocharger and exhaust manifold. They prevent exhaust leaks, maintain proper exhaust velocity, and protect nearby components from gas intrusion.

Turbo Connection and Flange Gaskets

Precision-cut gaskets that fit perfectly at every turbo flange and connection point. They are made from reinforced composite materials designed to endure repeated heating and cooling cycles without degradation.

Turbo Oil Supply and Return Gaskets

Sealing gaskets for both the oil feed and return lines ensure leak-free turbo lubrication. Proper oil sealing prevents pressure loss, oil leaks, and potential bearing contamination — all vital for turbocharger longevity.

Marine Exhaust and Spacer Gaskets

Used at turbo riser and manifold flange connections, these gaskets maintain exhaust flow efficiency and prevent leaks in marine exhaust paths. They are reinforced with metal cores to handle vibration and constant heat exposure.

Turbo Hardware and Fasteners

The reliability of the turbo system also depends on the hardware that holds it together. Diesel Pro Power provides durable, corrosion-resistant fasteners specifically made for the 8V71.

Turbo Studs and Bolts

Engineered to secure the turbo housing and flanges, these fasteners feature precise threading and high tensile strength to withstand extreme stress. They resist corrosion and maintain proper torque under vibration.

Turbo Washers and Nuts

Hardened washers distribute the tightening load evenly, while locking nuts prevent loosening due to vibration or heat cycling. Together, these ensure long-term stability and a perfect seal between connected components.

Turbo Clamps, Connectors, and Adaptors

Connecting the turbocharger to the rest of the exhaust and intake systems requires high-strength clamps and connectors. Diesel Pro Power’s range of clamps, risers, and adaptors ensures secure and reliable fitment throughout the 8V71’s turbo system.

Turbo Clamps

Available in multiple diameters, these stainless-steel V-band clamps provide consistent clamping pressure, ensuring leak-free joints between pipes and housings. They’re designed for quick installation and removal, allowing easy service access while maintaining strength under high boost pressure.

Turbo Riser Connectors

Heavy-duty connectors link the turbo outlet to the exhaust riser. They are built to handle high exhaust temperatures, maintain alignment under vibration, and prevent gas leaks that could reduce turbo performance.

Turbo Flange Adaptors

Adaptors provide a precise fit between turbo outlets and downstream components when slight diameter differences exist. Machined from cast steel, they guarantee smooth exhaust flow and structural integrity under heat stress.

Turbo Heat Blankets and Riser Covers

Heat control is essential in marine turbocharged engines. Diesel Pro Power offers Coast Guard-approved thermal blankets to protect surrounding components and maintain safety.

Turbo Blankets

Each turbo blanket is made of heavy-duty heat-resistant material reinforced with stainless-steel stitching and wire. These blankets contain radiant heat within the turbo housing, improving turbo spool efficiency while protecting adjacent engine components.

Left and Right Riser Blankets

Designed for the 8V71’s twin-bank configuration, these riser blankets cover both exhaust risers to maintain uniform temperature and improve safety. They help reduce engine room heat and protect operators during inspections or maintenance.

Benefits include:

• Lower engine room temperatures

• Improved turbo response due to retained exhaust energy

• Enhanced operator safety and component longevity

Air Intake Components and Walker Airsep Systems

A clean, unrestricted air supply is vital for turbocharger efficiency. Diesel Pro Power offers Airsep filtration systems and accessories that enhance the 8V71’s performance while reducing contamination and crankcase emissions.

Walker Engineering Airsep System

The dual Airsep configuration for twin-turbo 8V71 engines combines air filtration, silencing, and crankcase ventilation. This system maintains clean intake air, reduces oil mist buildup, and ensures consistent turbo boost pressure.

System advantages:

• Enhanced airflow and reduced restriction

• Improved engine room cleanliness

• Lower oil carryover in the intake system

• Meets marine emission and safety standards

Airsep Filters

Available in multiple tapered sizes to accommodate various space constraints, these filters deliver high filtration efficiency while minimizing airflow restriction. Their durable construction withstands moisture and vibration common in marine environments.

Airsep Springs and Regulators

Spring sets maintain proper filter tension and support, while vacuum regulators balance crankcase pressure and airflow. Together, they preserve the stable operation of the Airsep system and extend component life.

Airsep Filter Cleaning Kits

Regular cleaning of Airsep filters restores airflow capacity and extends filter service life. Diesel Pro Power’s cleaning kits make maintenance simple, cost-effective, and environmentally safe.

Hump Hoses and Intake Connectors

The 8V71 turbo system relies on flexible connectors to absorb vibration and allow for minor movement between engine-mounted and fixed components.

Straight Hump Hoses

These silicone hoses provide durable, flexible connections between turbo, intercooler, and intake pipes. Their heavy reinforcement allows them to withstand high pressure and temperature variations without collapsing or cracking.

Reduction Hoses

Reduction-style hoses smoothly transition between different pipe diameters, ensuring consistent airflow and minimizing turbulence. Their smooth inner walls and high-temperature silicone material provide long-lasting performance and leak-free sealing.

Key advantages:

• Resistant to oil, heat, and salt exposure

• Reinforced multi-layer construction

• Designed for vibration-prone marine installations

• Simple installation using standard clamps

Turbo Silencers and Filtration Accessories

To achieve quieter operation without sacrificing performance, Diesel Pro Power provides turbo silencers and silencer filters compatible with Detroit Diesel 8V71 systems.

Turbo Silencers

Mounted at the turbocharger air inlet, silencers reduce the characteristic whistle of high-speed turbines while maintaining full airflow. Built from corrosion-resistant aluminum or stainless steel, they are ideal for enclosed engine rooms and cabin cruisers.

Silencer Filter Elements

Replaceable filter elements fit inside the silencer housing to remove airborne contaminants before they reach the turbocharger. Regular replacement prevents damage to the compressor wheel and ensures clean airflow.

High-Temperature Jointing Compounds

Proper assembly of turbo components requires reliable high-temperature sealants. Diesel Pro Power supplies jointing compounds specifically formulated for turbocharger and exhaust applications.

Key Features:

• Withstands extreme heat and vibration

• Prevents exhaust gas and oil leakage

• Non-corrosive and compatible with aluminum and cast iron surfaces

• Ideal for sealing exhaust manifolds, flanges, and turbo housings

Using the correct sealant during installation helps ensure long-term reliability and prevents rework or early gasket failure.
