CORE TECHNICAL DIVISIONS

Every critical subsystem is engineered, machined, wired, and validated under one roof to guarantee mechanical and aerodynamic harmony.

COMBUSTION, INDUCTION & CALIBRATION

High-specific-output flat-four engines engineered for instant transient boost response and endurance reliability. Dynamically balanced assemblies calibrated across full load/RPM matrices with cylinder-individual EGT and knock protection.

CLOSED-DECK EJ25 3-STAGE DRY SUMP MOTEC M1 / SYVECS TWIN-SCROLL / ALS HUB DYNO CELL

TECHNICAL DELIVERABLES

  • CNC closed-deck block reinforcement & billet rotating assemblies
  • 5-axis cylinder head porting, custom cam profiles & titanium valvetrain
  • Equal-length twin-scroll tubular manifolds, Inconel shielding & V-mount cooling
  • Closed-loop boost, anti-lag (ALS), launch control & multi-fuel ECU strategies

KINEMATICS, FABRICATION & DAMPER VALVING

Mechanical grip starts with a torsionally rigid chassis and accurate suspension geometry. We fabricate FIA-spec 4130 chromoly cages, convert suspension pivots to aerospace spherical bearings, and custom-valve 3/4-way dampers.

4130 CHROMOLY TIG TUBULAR SUBFRAMES SPHERICAL BEARINGS 3/4-WAY COILOVERS CORNER-WEIGHT SCALES

TECHNICAL DELIVERABLES

  • Seam-welded shells, FIA roll cages & lightweight tubular front/rear subframes
  • Roll-center correction, bump-steer elimination & anti-dive/anti-squat geometry
  • Custom damper force-velocity valving, spring rate selection & blade sway bars
  • Digital 4-corner weight distribution, kinematic alignment & brake bias setup

CFD AERODYNAMICS & AUTOCLAVE COMPOSITES

Functional downforce without excessive drag penalty. Using 3D laser chassis scanning and RANS CFD simulations, we engineer balanced front-to-rear aerodynamic packages manufactured from autoclave prepreg carbon fiber.
