Yella Terra Press on Pulley - 87 mm.
The most cost effective way to wind up the boost and punch some life into your supercharged L67! Noticeably crisper/snappier throttle response across rev range.
Precision machined from quality aircraft grade aluminium.
Can be installed in-situ with any branded pulley removal/installation tool. However we recommend a hydraulic press to eliminate any chance of shaft damage.
Tune is always advised when increasing the performance of your engine to ensure maximum horsepower from your investment.
