Features

SUPERCHARGED POWER

The LT4 features a 1.7L Eaton® R1740 TVS supercharger, which spins at up to 20,000 rpm. That’s enough to generate more than 9 lbs of boost and help produce 650 horsepower and 650 lb-ft of torque.*

* @6600 rpm

Additional Features

  • 1.74 L/rev supercharger
  • Integrated dual coolant to air intercooler
  • Variable Valve Timing (VVT) allows linear delivery of torque, with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without sacrificing overall engine response, or drivability.
  • Electronic throttle control
  • Dual-pressure control and variable displacement oil pump
  • Extended-life spark plugs have an iridium electrode tip and an iridium core in the conductor. Its “self-cleaning” properties are improved, decreasing potential for plug fouling and further reducing the likelihood of maintenance over the 100,000-mile plug life. The electrode design improves combustion efficiency for maximum fuel economy and minimum emissions.
  • The 58X crankshaft ring and sensor provide more immediate, accurate information on the crankshaft’s position during rotation. This allows the ECM to adjust ignition timing with greater precision, which optimizes performance and economy. Engine starting is also more consistent in all operating conditions.
