CTS Turbo Audi 3.0T Supercharger Pulley Upgrade Kit

  • Sale
  • Regular price $159.99

This pulley is a smaller diameter than stock, at 57.3mm, increasing the speed at which the supercharger spins, increasing the boost pressure output.  Increased boost pressure in conjunction with upgraded ECU software results in a dramatic increase in horsepower and torque throughout the entire powerband. This will not increase stress or excessive wear on supercharger or engine components.

NOTE: This Supercharger Pulley Upgrade Kit must be used with appropriate “Stage 2” performance software. There will be no power gains if you install this pulley without Stage 2 software.
Stage 2 performance software will allow you to achieve maximum boost and power from your 3.0T S/C engine while safely optimizing air-fuel ratios, timing, and boost pressure bleed off.


Stock pulley size: 63.20mm

CTS pulley size: 57.30mm
