Harrop Stage 4 390 kW
Since
1955, Harrop has engineered and manufactured world-class performance products
for a diverse range of applications. Whether it is original equipment for Ford,
Holden & Lotus or premier motorsport categories such as F1, NASCAR & V8
Supercars, or our proprietary aftermarket performance products; our reputation
is legendary.
The Harrop
Stage 4 package for the LS3 V8 Commodore is designed for drivers chasing a
serious lift in performance, sound and attitude, with outputs around 410 kW at
the flywheel. By significantly improving airflow in and out of the engine
through a Harrop over-the-radiator cold air intake, free-flowing exhaust
system, 4-into-1 headers and high-flow catalytic converters, the LS3 is primed
for its next step. A carefully matched performance camshaft and upgraded
valvetrain then transform the engine’s character, delivering harder
acceleration, a stronger mid-range and an unmistakable top-end surge. Each
vehicle is custom calibrated on the dyno for 98 RON fuel and validated on the
road to ensure crisp throttle response and refined drivability.
