Yella Terra Holden VN–VS 5.0L 3.4L Radial Whipple Supercharger Kit

$12,936.00

Yella Terra and Whipple Australia’s 3.4L radial top-entry system is a complete high-output supercharger package for Holden 5.0L combinations using VN-style asymmetric-port cylinder heads. The current package uses Whipple’s Gen-4 W200R twin-screw supercharger and is designed for both carburettor and EFI top-entry induction.

Gen-4 Whipple performance

3.4L Whipple W200R radial twin-screw supercharger with latest Gen-4 rotor technology.
Supplier-rated for 900+ hp potential and up to approximately 25 psi on a suitable engine combination.
Improved rotor sealing, airflow efficiency and thermal performance over earlier-generation designs.
Low-line open-plenum manifold is designed for strong low-speed torque while maintaining high-RPM airflow.
Radial top-entry arrangement supports carburettor or EFI throttle-body configurations.

CNC manifold and fuel-system flexibility

CNC-machined manifold designed for Holden VN-style asymmetric-port heads.
Cast injector bosses are provided for direct manifold-port injection and can be blocked when using through-blower injection or carburettor induction.
Manifold is prepared to support a future water-to-air intercooler upgrade without adding supercharger height.
Overall height from manifold base to throttle-body base is approximately 275 mm.

Independent 10-rib drive

Dedicated heavy-duty 10-rib supercharger drive keeps blower load separate from the normal accessory drive.
Billet crank pulley suits the factory harmonic balancer.
Billet support plate, heavy-duty tensioner arrangement and 10PK belt are engineered for high boost and high RPM.

Base kit — YT 4083TKR-1

3.4L W200R Gen-4 radial Whipple supercharger in non-intercooled configuration.
CNC radial top-entry manifold and bypass-valve system.
Heavy-duty independent 10-rib billet drive system.
EFI and carburettor compatibility, including manifold-port injection using factory or aftermarket fuel rails.

Upgrade options — YT 4083TKR-2

Roller-cam drive upgrade where required on later Holden 5.0L combinations.
Alternative 10-rib pulley diameters for different boost requirements.
Water-to-air intercooler package with billet inner core, heavy-duty water pump, triple-pass front heat exchanger and billet reservoir.

Carburettor installations: Some combinations may require a separate top-angle plate.
