Performance component catalogue engineered for zero fitment compromise.

Cast commercial turbochargers frequently fail on race circuits due to radial shaft deflection and turbine housing fatigue under temperatures above 900°C. Factorys Five builds competition twin-scroll assemblies using solid Inconel 718 turbine wheels balanced to within 0.005 gram-inches. The cartridge features dual ceramic ball bearings retained within a billet steel carrier, reducing frictional drag by 42% over bronze sleeve journals.

The compressor wheel is CNC machined from aerospace 2618 forged aluminum with an aggressive 58 mm inducer and extended-tip blade architecture. Each unit is fitted with a matched high-pressure internal wastegate actuator calibrated to customer boost targets before dispatch.

Cracked exhaust runners and stripped turbo mounting studs originate from drivetrain torque flex transferring directly into rigid exhaust piping. We eliminate this failure mode by integrating a double-braided stainless steel flex bellows rated for continuous 950°C thermal cycling.

All exhaust kits are constructed from seamless 16-gauge T304 stainless steel tubing, mandrel-bent on smooth-radius dies with zero diameter necking or flow constriction. Flanges are CNC laser cut from 12.7 mm (1/2-inch) plate and surfaced after TIG welding to guarantee planar sealing without gasket blowout.

Unmetered air leaks and turbulence across the mass airflow sensor cause unstable idling, erratic fueling trims, and dangerous lean conditions under full boost. Our cold air induction kits use a spun aluminum 4.0-inch velocity stack mouth designed to stabilize air boundary layers into a laminar column before entering the intake charge pipe.

The filter element features a multi-layer synthetic oiled crimson cotton mesh supported by an epoxy-coated wire structure that will not collapse under 2.2 bar compressor depression. A laser-cut 5052 aluminum heat shield isolates the intake element from radiator heat wash.

Stamped factory suspension arms deflect under cornering loads, altering alignment geometry mid-turn and causing unpredictable oversteer. We manufacture tubular A-arms and trailing links from seamless 4130 aircraft-grade chromoly tubing with 0.095-inch wall thickness.

Every joint incorporates Teflon-lined self-lubricating FK spherical rod ends to eliminate compliance while maintaining smooth articulative movement without binding. Our camber and caster adjustment assemblies feature CNC-machined turnbuckles with laser-etched 0.5 mm hash marks, enabling trackside alignment adjustments in under four minutes.

Single-disc clutch systems holding high turbocharged torque require extreme pressure plate clamp loads that bend clutch release forks and strain pedal hydraulics. Our multi-plate driveline clutch package divides torque distribution across dual cerametallic friction plates, maintaining light, manageable pedal effort while holding up to 850 lb-ft of torque.

The pack includes a forged 4140 chromoly flywheel with integral starter ring gear, lightened by 38% compared to cast OEM units to decrease rotational inertia and sharpen engine acceleration out of apexes. The assembly is dynamically spin-balanced to 10,000 RPM on our Wareham balancing rig.

Vibration and galvanic corrosion loosen standard hardware on competitive sports car chassis. Our precision fitment hardware packs consist of high-tensile grade 10.9 zinc-nickel flanged fasteners engineered to resist 1,000 hours of salt spray exposure without hydrogen embrittlement.

We accompany every kit with stepped centering shims turned from 6061-T6 aluminum on our CNC lathe, held to within 0.05 mm concentricity. Sealing interfaces utilize high-temperature Viton fluorocarbon O-rings rated for continuous 230°C immersion in synthetic oils, race fuels, and ethanol blends.
