Fabspeed

Fabspeed Motorsport is a Pennsylvania-based performance parts manufacturer that specializes in exhaust systems, sport catalytic converters, headers, downpipes, intake systems, and carbon fiber components engineered specifically for exotic and high-performance European sports cars including Porsche, Ferrari, Lamborghini, McLaren, BMW M, and Audi R8. Every Fabspeed product is TIG-welded from aerospace-grade stainless steel or titanium in the USA, dyno-tested for measurable power and sound improvement, and designed as a direct bolt-on replacement that preserves the factory catalytic converter monitoring system or provides an explicit sport cat solution for emissions-compliant upgrades. Exotic car owners who have already maximized software and cosmetic modifications choose Fabspeed exhaust systems because the brand's specialty focus on a narrow range of platforms produces fit quality and sound character that universal exhaust manufacturers cannot achieve. The brand's XperTune ECU calibr...

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 Upgrade Components

Turbo Upgrade Components

Turbo upgrade components are the individual performance parts used to improve boost response, increase peak power, extend turbocharger life, and support higher boost pressure targets on turbocharged engines. Selecting the right combination of upgrade components allows a progressive approach to forced induction performance tuning without replacing the entire turbocharger. Popular Turbo Upgrade Components Common turbo upgrade components include high-flow wastegates and external wastegate manifolds for precise boost control above stock limits, upgraded blow-off and bypass valves for cleaner compressor surge management, billet compressor wheel drop-in upgrades for increased airflow capacity, ported compressor and turbine housings for improved map width and efficiency, and turbo flanges and V-band clamps for leak-free exhaust plumbing connections. Intercooler upgrades are also closely associated with turbo stage builds to handle the increased charge temperatures generated by higher boost...
