Rotomaster New Turbocharger Product Line Details

The Rotomaster New Turbocharger line offers 100% new turbochargers designed to meet or exceed original equipment performance standards. This product line focuses on delivering reliable aftermarket turbochargers that comply with emission regulations and provide consistent power delivery for a range of vehicle applications, including Audi models.

Product Description and Features

This turbocharger is built with a journal bearing system, which provides durability and efficient rotation under high-speed conditions. The combination of steel and aluminum materials ensures a balance between strength and weight reduction. The integrated wastegate actuator helps regulate boost pressure, preventing over-boost scenarios. Cooling is managed through both oil and coolant channels, which helps maintain optimal operating temperatures and extends turbocharger life.

Common Applications and Issues Addressed

  • Restores engine power loss due to worn or damaged turbochargers
  • Eliminates excessive smoke caused by turbo failure or oil leaks
  • Resolves unusual noises or vibrations linked to turbo shaft play
  • Addresses boost pressure inconsistencies affecting engine performance
  • Prevents further engine damage by replacing failing turbo components

Installation Notes and Tips

  • Ensure engine oil is changed regularly to prevent oil starvation and turbo damage
  • Allow the engine to cool before shutdown to protect the turbocharger from heat soak damage
  • Replace air filters and clean air and exhaust systems to avoid foreign object damage
  • Inspect for axial end play and wheel damage before installation
  • Use included gaskets, washers, studs, and syringes for proper sealing and lubrication

Troubleshooting TipA decrease in engine power may be your first indication your turbocharger is damaged or has failed.
Troubleshooting TipAny nicks, scratches, or chips on either wheel are evidence foreign object damage caused by contaminants entering the airflow to or from the engine.
Troubleshooting TipAxial end play of the wheels and shaft in and out greater than the thickness of a sheet of paper indicates a worn thrust bearing due to excessive exhaust backpressure.
Troubleshooting TipBefore a failed turbocharger is replaced the original cause of failure must be diagnosed and corrected to protect the new installation.
Troubleshooting TipCommon signs of wear indicating replacement may be required:
Troubleshooting TipWorn engines with excessive blow by will result in crankcase pressurization, leading to oil leaking from the turbochargers internal seals. This may result in oil deposits in the intake manifold or smoke in the exhaust. This is not necessarily a sign of a failed turbocharger, but rather a sign that the engine needs to be rebuilt or replaced.
