Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
