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.
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Turbos, Superchargers, and Boost the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
