Yella Terra Holden L67 2.4L Whipple A2A Supercharger Upgrade — YT L6724A2A

$8,460.00

Yella Terra and Whipple Australia developed this 2.4L twin-screw air-to-air upgrade for 1995–2004 Holden Commodore VS–VY models using the supercharged L67 V6, as well as Series II Buick 3800 applications. It replaces the factory Eaton M90 with a substantially larger Whipple twin-screw supercharger for stronger airflow, torque and throttle response while retaining an independent supercharger drive.

Performance and application

Latest-generation 2.4L Whipple twin-screw supercharger.
Designed to replace the factory M90 on L67 combinations already fitted with the required generic air-to-air intercooler manifold.
Yella Terra / Whipple Australia states the package is capable of producing up to approximately 600 RWHP on a suitable supporting combination.
Developed for Holden L67 / Series II Buick 3800 supercharged engines.

Kit features

CNC-machined air-to-air adapter plate.
High-flow 100 mm rear inlet with an integrated bypass system.
Rear inlet is configured for an LS1-style throttle body.
Billet supercharger snout suits the factory independent 6-rib drive arrangement.
Includes the required base gasket, gasket sealer, supercharger oil and installation hardware.

Not included

Air-to-air intercooler manifold — the vehicle must already have the required A2A manifold arrangement.
LS1-style throttle body.
Supercharger pulley.

Compatible supercharger pulleys are available separately in 6-rib and 8-rib configurations, with diameters ranging from approximately 87 mm down to 61 mm.

Installation and calibration: Final pulley size, boost pressure, fuel-system capacity, charge cooling and ECU calibration must be matched to the engine combination. Professional installation and custom tuning are recommended.
