SCG 004C: The Glickenhaus “Competizione” Rework
The 004C is the racing evolution of the 004S, replacing the legendary 003C. In reality, racing regulations for the classes Glickenhaus targets (GT3, GTE, and SP-X) rarely favor supercharging. This rework aligns the car with its 2024–2026 racing specifications, emphasizing the low-center-of-gravity advantage of its small-block V8.
The 6.2L LT4 “NA” Conversion: Autotechnica Spec
While the road-going 004S is supercharged, the 004C racer uses an engine developed by Autotechnica Motori specifically for endurance reliability:
- Engine Calibration: We have stripped the twin-turbo/supercharger logic and remapped the 6.2L V8 as a Naturally Aspirated unit. It now produces a BoP-compliant 520–550 hp with a massive 720 Nm (531 lb-ft) of torque.
- Low-Rev Grunt: Following Jim Glickenhaus’s own description, the engine doesn’t rev to F1 heights but offers incredible mid-range torque and cooling efficiency. We have simulated the 16-injector LT block logic for a smooth, high-displacement power delivery.
- 6-Speed Xtrac Sequential: The drivetrain has been converted from a standard manual to the Xtrac sequential transmission. Shift times and gear ratios are now set to prototype endurance specs, providing that sharp, racing “clunk” on every gear change.
Aerodynamics & Chassis: The “SP-X” Balance
The 004C is famously “massively faster” than its predecessor due to its refined aero balance:
- Balanced Downforce: We have rebalanced the aero map to correct the understeer issues of earlier mod versions. The car now features roughly 500 kg of downforce, split effectively between the “GT3-style” rear wing and the aggressive front canard/splitter combination.
- Central-Seat Geometry: We have adjusted the suspension geometry and roll centers to account for the unique central driving position. This gives the car a neutral rotation feel that is distinct from traditional left or right-hand drive GT3s.
- Dampers & Brakes: Modeled the KW racing dampers and AP Racing brake package to ensure the 1,117 kg chassis can be driven deep into corners with absolute confidence.
Visual & Technical Enhancements
- Graphics Extension: Added custom CSP extension tweaks to enhance the unpainted carbon-fiber textures and the digital racing dashboard.
- Bug Fixes: While the 3D model lacks a functional wiper, we have optimized the windshield shaders for better visibility in the wet.
- Fixed Collider: A new 3D collider has been generated to ensure the car interacts properly with the Nürburgring’s aggressive curbs.
Installation Requirements
Note: This physics and graphics configuration is designed for compatibility with the RTM model.
