NEED HELP?

IS YOUR VEHICLE PERFORMANCE ABNORMAL ESPECIALLY AFTER RECENT SERVICE OR INSTALLATION?

HERE ARE A FEW IDEAS TO HELP POINT YOU IN THE RIGHT DIRECTION:

- Vehicles can have many complex variables that directly & indirectly contribute to how a turbocharger performs. A perfectly operational turbocharger may exhibit erratic or lack of performance due to other system problems included but not limited to fueling, boost leaks, unstable or loose connections, electrical systems, fuses & sensors, internal engine issues or tuning. As an exclusive turbocharger supplier/manufacturer Turbo Time USA is unable to offer vehicle troubleshooting/tech advice or diagnostics for your specific vehicle. Customers experiencing performance concerns will need to have their vehicle inspected & diagnosed by a reputable certified service center. -

FAQs

MY NEW TURBO HAS "SHAFT PLAY". IS IT BAD?

  • MANY TURBOCHARGERS HAVE VARYING RANGES OF "PLAY" OR SIDE TO SIDE MOVEMENT. JOURNAL BEARING TURBOS REQUIRE SPACE WITHIN THE BEARING SYSTEM ALLOWING OIL FLOW TO SUSTAIN A BARRIER OF OIL STABILIZING THE SHAFT DURING OPERATION.
  • IT IS NOT UNCOMMON TO NOTICE INCREASED MOVEMENT AFTER OPERATION WHEN THE TURBO AND OIL IS UP TO OPERATING TEMPERATURE. MATERIAL EXPANDS ALLOWING ADDITIONAL MOVEMENT.

WHAT IS THAT NOISE?

  • BAD CONNECTION POINTS OR LEAKS CAN PRODUCE DIFFERENT NOISES & LEVELS OF VOLUME.
  • LEAKS ARE OFTEN TRICKY TO FIND AND MAY REQUIRE SPECIFIC TOOLS & TECHNIQUES TO LOCATE.

DOES YOUR TURBO SEEM "LAGGY" OR NOT PRODUCING BOOST?

  • INSTALLING A LARGER PERFORMANCE TURBOCHARGER MAY CAUSE A MISCOMMUNICATION BETWEEN THE VGT SYSTEM & ECU. OFTEN TIMES A "VGT RELEARN" OR TUNE CAN HELP RESET THIS & HAVE YOU RUNNING EFFICIENTLY.
  • POSSIBLE FUEL DELIVERY PROBLEM WITHIN YOUR FUEL SYSTEM .
  • DURING SERVICE OR INSTALLATIONS SOMETIMES NEW PROBLEMS ARISE OR CONNECTIONS NOT CORRECT.
  • CHECK FOR LEAKS

WHY AM I NOT SEEING MORE BOOST PSI?

  • PERFORMANCE TURBOCHARGERS ARE DESIGNED TO PRODUCE AND PROCESS MORE CFM PER PSI INCREASING POWER AND EFFICIENCY. THEREFORE YOU CAN EXPERIENCE MORE POWER AT THE SAME PSI AS YOUR PREVIOUS TURBO.
  • INCREASING FUEL SUPPORT WILL HELP PRODUCE HIGHER BOOST PSI.
  • TUNING CAN CONTROL OR LIMIT THE AMOUNT OF BOOST PRODUCED.
  • THE VGT SYSTEM CAN BE MANIPULATED IN TUNING.
  • FACTORY SENSORS AND MONITOR SYSTEMS OFTEN LIMIT BOOST READINGS. ANALOG GAUGES HELP DISPLAY MORE ACCURATE READINGS.

WHY DO I HAVE ABNORMAL PERFORMANCE & CEL CODES?

  •  ENSURE SENSORS ARE CLEAN & CONNECTED PROPERLY
  • CHECK FOR BLOWN FUSES
  • CHECK FOR LEAKS
  • CHECK FUEL
  • CHECK AIR FILTER
