Description

Rotomaster Billet Compressor Wheels are engineered for strength, speed, and reliability, making them the ideal upgrade for high-performance or heavy-duty turbo applications. The compressor wheel is critical to turbocharger performance, delivering high-pressure air to the combustion chamber for increased power and efficiency. Unlike traditional cast aluminum wheels, Rotomaster billet wheels are CNC-machined from forged aluminum for superior strength, lower mass, and longer fatigue life. This results in faster spool-up, improved throttle response, and greater durability, perfect for racing, commercial fleets, buses, and delivery vehicles. Designed to meet or exceed O.E. performance standards, each wheel is precision-balanced for smooth operation and fits seamlessly into O.E. compressor covers. Built for endurance and tested under extreme conditions, Rotomaster Billet Compressor Wheels deliver performance you can count on mile after mile.

  • Consistent Mass Distribution – Milled for uniform weight and center of gravity to support smooth turbo operation and reduce vibration 
  • Forged Billet Construction – CNC-machined from high-strength forged aluminum for enhanced durability and resistance to fatigue 
  • OE-Level Fit and Performance – Engineered to meet or exceed original equipment performance standards for seamless compatibility and reliability 
  • Precision Machining – Manufactured to exacting tolerances for optimal balance, performance, and boost efficiency 
  • Superior Strength – Stronger than standard cast aluminum compressor wheels, delivering extended service life under high-stress conditions

INITIAL INSPECTION AND GENERAL CARE 

  1. Carefully inspect the air cleaner, air cleaner duct, and the exhaust manifold for any foreign material. Objects left in these areas can severely damage the turbocharger immediately on engine startup. 
  2. Remove old gaskets and left-over material from the exhaust manifold, the oil supply line and oil drain line flanges. Inspect these surfaces for cracks, flatness, or erosion. 
  3. Inspect the oil supply and drain lines for degradation and cracking.  
  4. Make sure that there are no kinks or any other type of restriction or clogging in either line.
