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 Cartridges
A turbo cartridge, also called a CHRA (center housing rotating assembly), is the internal core of a turbocharger containing the turbine shaft, journal bearings or ball bearings, seal rings, and thrust bearing. Replacing the CHRA is a cost-effective turbocharger rebuild method that restores performance and oil sealing without replacing the turbine housing and compressor cover. Popular Turbo Cartridge Applications CHRA cartridges are available for a wide range of OEM and aftermarket turbocharger frames including Garrett, Borg Warner, IHI, Mitsubishi, and Holset turbos used in popular diesel and gasoline turbocharged applications. Ball bearing CHRA upgrades are available for many journal bearing turbo frames, offering faster spool response, reduced oil consumption, and longer service life than the original journal bearing assembly. When should a turbo cartridge be replaced? Turbo cartridge replacement is appropriate when inspection reveals shaft play exceeding manufacturer tolerances, ...
