CTS Turbo Crank Pulley Upgrade (180 mm / 187 mm / 190 mm)
The CTS Turbo crank pulley is larger than the original and is made from precision-machined T6061 aluminum. It replaces the original two-piece pulley structure and reduces the rotating mass of the crankshaft, which frees up engine power for more efficient use.
A larger pulley diameter increases the supercharger's rotational speed and boosts boost pressure. Combined with an engine management software upgrade, this allows for a significant increase in power and torque across the entire RPM range. The upgrade does not cause undue stress or abnormal wear to the supercharger or engine when used with properly tuned software.
Options:
-
180 mm – Moderate power increase, suitable for daily use.
-
187 mm – Popular mid-size, offers more boost pressure and power.
-
190 mm – Maximum supercharger overspin without a two-pulley system, requires appropriate software and cooling upgrades.
Please note:
This product should be used with performance software matching the selected pulley size. A more efficient intercooler or heat exchanger is recommended and, for larger sizes, practically essential. A software upgrade (not included) will safely optimize the air-fuel ratio, ignition timing, and boost pressure control.
