  • A/R ratio (smaller ratio = quicker spool, larger ratio = higher top-end power)
  • Flow capacity (measured in lb/min or CFM)
  • Turbo trim and inducer/exducer dimensions

Wastegate

Controls boost pressure by regulating exhaust flow through the turbine. Available as:

  • Internal wastegates (integrated into turbo housing)
  • External wastegates (separate component for better control)
  • Spring pressure ratings (typically 5-26 PSI)
  • Actuator types (pneumatic, electronic)

Intercooler

Cools compressed air before it enters the engine, increasing density and reducing detonation risk:

  • Air-to-air (uses ambient air for cooling)
  • Air-to-liquid (uses coolant for more efficient heat transfer)
  • Core size and efficiency ratings
  • Pressure drop specifications

Blow-Off Valve (BOV)

Releases pressure when throttle closes to protect turbo and improve response:

  • Atmospheric (vents to atmosphere with signature sound)
  • Recirculating (returns air to intake)
  • Hybrid designs (adjustable between both modes)
  • Flow capacity and spring rates

Oil Feed & Drain Lines

Critical for turbo lubrication and cooling:

  • Heat-resistant materials (braided stainless steel, high-temp hose)
  • Diameter specifications (typically -4AN feed, -10AN drain)
