Turbos, Superchargers, and Boost

Like Duolingo, but for Turbos, Superchargers, and Boost. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

21 levels across 4 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through Experiencing Boost: The Forced Induction Choices; Harnessing Exhaust Energy: Turbocharger Mechanics; The Thermal Battle: Intercooling and Air Density; and Managing Pressure, Exhaust Flow, and Engine Safety. It assumes you already know the basics.

Key ideas in Turbos, Superchargers, and Boost

  • Boost is intake backup pressure caused when a compressor out-flows the engine's air demand
  • Improving engine volumetric efficiency lets more air into cylinders, dropping manifold backpressure
  • A lower boost reading with better flow actually moves more total air mass into the combustion chambers
  • Belt-driven superchargers offer zero throttle lag because rotor speed directly mirrors crank speed
  • Compressing air mechanically consumes parasitic horsepower stolen straight from the engine's crankshaft
  • Parasitic drive losses rise steeply as engine RPM and target boost levels climb
  • Exhaust gas heat and expansion speed build first as cylinders fire under heavy load
  • Exhaust gas velocity spins the hot turbine wheel to spool the common shaft at high RPM
  • Intake compressor pressurizes the charge air until the wastegate diverts excess exhaust gas
  • Flat boost curves create broad, predictable grunt early in the rev range for effortless daily passing
  • Steep exponential turbo surges hit suddenly as boost threshold is crossed, easily upsetting chassis balance
  • Linear power curves allow precise throttle feathering while cornering at the tire traction limit
  • Forced induction raises dynamic compression and heats up the cylinder's unburned end-gas charge
  • High intake temps and lean air-fuel ratios push cylinder charges closer to spontaneous detonation
  • High-octane fuel resists premature auto-ignition caused by elevated dynamic compression ratios
  • Roots blowers transport fixed air pockets without shrinking them internally.
