Turbocharger Components

1. 4 WATER JACKET PORTS

FOR CUSTOM INSTALLATION. LARGER WATER JACKETS IMPROVES OVERALL COOLING CAPACITY. TWO PLUGS AND TWO 6AN FITTINGS INCLUDED.

2. OIL RESTRICTOR

DELIVERS THE RECOMMENDED OIL PRESSURE FOR PROPER BEARING LUBRICATION. A 1MM RESTRICTOR IS INCLUDED WITH GARRETT® G25-550 AND G25-660 TURBOCHARGERS.

3. TURBINE WHEEL

AERODYNAMICS IMPROVE FLOW AND BOOST RESPONSE. THE ALL NEW WHEEL DESIGN IS MADE OF MAR-M SUPER ALLOY AND CAPABLE OF HANDLING EXHAUST GAS TEMPERATURES UP TO 1050 DEGREES CELSIUS.

1. TWIN PISTON RINGS

ON BOTH SIDES OF THE SHAFT COMBINED WITH A NEW OIL DEFLECTOR HELP REDUCE OIL LEAKAGE FROM THE CENTER HOUSING TO THE COMPRESSOR AND TURBINE STAGE.

2. OIL DEFLECTOR

3. THRUST SHROUD

4. SEAL PLATE

5. BEARING CARTRIDGE

NEW COMPACT 8MM CARTRIDGE FEATURES CERAMIC BALL BEARINGS RESULTING IN LESS HEAT TRANSFER TO THE OIL. STEEL BEARING CAGES IMPROVE THE DURABILITY OF COMPLETE ASSEMBLY.

HOW A TURBO SYSTEM WORKS

Compressor Inlet: Opening through which ambient air passes before entering the compressor.
Compressor Discharge: Ambient air is then compressed which raises the air’s density (mass / unit volume).
‍Charge Air Cooler (aka Intercooler): cools the compressed air to increase its density and to increase resistance to detonation.
‍Intake Manifold: Directs dense air into the engine’s cylinders. Each cylinder draws in an increased mass flow rate of air. Higher air mass flow rate allows a higher fuel flow rate (with similar air/fuel ratio). Combusting more fuel results in more power for a given displacement.
‍Exhaust Manifold: Directs burned fuel and exhaust gasses from the cylinders towards the turbine.
‍Turbine Inlet: Directs high temperature exhaust gas towards the turbine wheel. The turbine creates back pressure on the engine which means engine exhaust pressure is higher than atmospheric pressure.
‍Turbine Discharge: A pressure and temperature drop occurs (expansion) across the turbine, which harnesses the exhaust gas’ energy to provide the power necessary to drive the compressor wheel.
