Yella Terra Holden L67 Press-On Pulley & Idler Kit — 82mm / 87mm

Yella Terra’s press-on pulley and oversized-idler kit is a simple boost upgrade for the Holden L67 supercharged V6. The smaller drive pulley increases supercharger speed while the oversized idler takes up belt slack so the factory-length belt can be retained.

Pulley choices

• 87 mm pulley — approximately 9–10 psi on an otherwise unmodified vehicle according to Yella Terra.
• 82 mm pulley — approximately 10–12 psi on an otherwise unmodified vehicle according to Yella Terra.
• Precision-machined aircraft-grade aluminium pulley with anodised finish.
• Factory-style appearance for a discreet under-bonnet installation.
• Oversized idler eliminates the need for a special shorter belt.

Installation

• Can be installed in situ with a suitable pulley removal / installation tool.
• Yella Terra recommends using a hydraulic press where possible to minimise the chance of supercharger-shaft damage.
• Tuning is recommended whenever boost and engine performance are increased.

Note: Quoted boost figures are based on otherwise unmodified vehicles and vary with the complete engine setup.
