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...

Turbochargers

Turbochargers

Turbochargers use exhaust gas energy to spin a turbine wheel that drives a compressor wheel on a shared shaft, compressing intake air above atmospheric pressure and forcing a denser charge into the engine's cylinders. More air allows more fuel to be burned per cycle, producing substantially more power and torque from the same engine displacement. Popular Turbocharger Options Popular replacement and upgrade turbochargers include drop-in OEM-equivalent units for restoring factory performance after turbocharger failure, bolt-on upgraded turbochargers sized for 20 to 40 percent power gains on stock internals, and large-frame high-output turbochargers for built engine applications targeting 600 horsepower and above. Leading turbocharger brands include Garrett, Borg Warner, IHI, Mitsubishi, Holset, and Precision Turbo, each offering a range of frame sizes and bearing configurations for different applications. How do I choose the right size turbocharger? Turbocharger sizing is determined b...
