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...

Go Fast Bits
Go Fast Bits (GFB) is an Australian performance engineering company specializing in blow-off valves, bypass valves, and boost management components for turbocharged performance vehicles. The brand is particularly well-known for its TMS, T9H, and Respons adjustable blow-off valves that allow drivers to tune the valve's response characteristics between full atmosphere venting (traditional BOV sound) and full recirculation (OEM-style operation), giving owners control over both the performance and sound character of the boost control system. GFB components are manufactured to precision engineering tolerances and designed to outperform both stock bypass valves and lower-quality BOV alternatives, maintaining consistent boost pressure control at elevated boost levels where factory valves begin to leak. The catalog covers direct-fit applications for popular turbocharged platforms from Subaru WRX and STI to Volkswagen Golf R, Audi S3, and Ford Focus ST. Popular Upgrades The GFB TMS Respons b...
