Forced Induction

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...

Turbo Compressor Covers

Turbo Compressor Covers

The turbo compressor cover, also called the compressor housing, is the snail-shaped aluminum casting that surrounds the compressor wheel and directs compressed intake air to the engine's throttle body or intercooler. Upgrading or replacing the compressor cover affects the flow capacity of the turbocharger and is a key component in turbocharger rebuilds and stage upgrades. Popular Turbo Compressor Cover Options Larger compressor cover A/R ratios support higher airflow targets at the cost of slower low-RPM spool. Smaller A/R compressor covers spool faster and are better suited to street-driven applications where low-end response is a priority. Ported or map-width-enhanced compressor covers extend the usable compressor map range and reduce surge at low mass flow conditions, making them popular on applications with large intercoolers or tight boost controller setups. When does a compressor cover need replacement? Compressor cover replacement is needed when the housing bore shows scoring...
