Automotive assembly kits, high-flow turbo systems, and precision hardware fabrication
Factorys Five specializes in the development, testing, and distribution of sports car build kits and competition automotive components. We assist car builders, grassroots racers, and custom shops in assembling high-performance vehicles with zero universal compromises.
Our core commercial offerings comprise six distinct engineering categories:
- Twin-Scroll Turbocharger Assemblies: High-temperature Inconel 718 turbine wheels, dual-ceramic ball bearing cartridges, and matched wastegate housings ($489.00–$629.99 USD).
- Mandrel-Bent Downpipe Kits: 3.0-inch 16-gauge T304 stainless steel tubing with CNC laser-cut 1/2-inch flanges and back-purged TIG welds ($289.00–$449.00 USD).
- High-Flow Air Induction Systems: Multi-layer oiled synthetic cotton elements, 4.0-inch velocity stack inlets, and thermal aluminum heat shields ($149.00–$289.00 USD).
- Tubular Suspension Control Arms: TIG-welded 4130 chromoly tubular bodies, Teflon-lined FK rod ends, and laser-etched alignment hash plates ($360.00–$580.00 USD).
- Multi-Plate Driveline Clutch Packs: Dual cerametallic friction discs and forged chromoly flywheels rated up to 850 lb-ft torque ($389.00–$619.00 USD).
- Precision Fitment Hardware: Grade 10.9 zinc-nickel flanged fasteners, stepped centering shims, and Viton fluorocarbon seals ($5.99–$49.99 USD).
We operate on an inquiry-only basis. We do not provide an automated checkout because every race chassis requires fitment verification before components are packed and dispatched.
“We machine 6061-T6 aluminum flanges to 0.02 mm flat so you never blow a collector gasket at full boost.”
Granite surface plates, pneumatic leak testing, and digital dynamic balancing
Universal fitment compromises lead to trackside failure. Many aftermarket suppliers source thin cast housings overseas that warp after initial heat cycles. Inside our Wareham facility, every production run is subjected to three mandatory physical inspections before boxing:
1. Granite Surface Plate Inspection: Control arms, suspension uprights, and tubular brackets are clamped to our certified grade-A granite surface plate. Mitutoyo digital height gauges and mechanical vernier calipers verify hole-to-hole centerlines within 0.05 mm of master CAD blueprints.
2. 45 PSI Pneumatic & Hydrostatic Hold: Fabricated exhaust collectors, intercooler piping, and turbo housings undergo immersion leak testing under 45 psi pneumatic pressure. Zero micro-bubbles are tolerated along weld seams.
3. High-Speed Core Balancing: Turbocharger rotating assemblies are balanced on our dynamic vibration bench across low, medium, and high RPM bands up to 120,000 RPM, achieving residual unbalance figures under 0.005 gram-inches.
