A turbocharger wins on efficiency because it runs off exhaust gases that would otherwise go to waste, while a supercharger draws mechanical power directly from the engine's crankshaft to force air into the intake.

Both a turbocharger and a supercharger compress intake air to push more oxygen into the combustion chamber — that's what makes power go up. The split happens at the energy source. A turbocharger uses a turbine spun by exhaust flow, adding no direct parasitic load on the crankshaft. A supercharger belts directly to the crankshaft, delivering immediate boost with zero lag but consuming horsepower in the process — typically 15–25% of what it produces.

  • Turbocharger energy source: exhaust gas driving a turbine — zero direct crankshaft draw.
  • Supercharger energy source: crankshaft belt drive — parasitic load estimated at 15–25% of output gains.
  • Turbo lag: measurable delay (typically 1–3 seconds) while exhaust flow builds enough pressure to spool the turbine.
  • Ford EcoBoost 1.5L and 2.0L engines use turbochargers, not superchargers — the two are not interchangeable platforms.
  • Superchargers deliver boost at near-zero RPM; turbochargers reach peak boost higher in the rev range.
