ATTEMPTING TO START THE WRECKED BUGATTI CHIRON PUR SPORT

This video documents a high stakes engineering challenge: reassembling and repairing a wrecked Bugatti Chiron Pur Sport in a non traditional workshop setting. The host explains early on that Bugatti refused to supply parts, forcing them to improvise using a mix of original components and home made or repaired parts. The team weighs two main repair strategies for a broken engine mount and gearbox bracket: CNC machined aluminum along a single piece versus repairing the original mount. They consult Bob at a machine shop, test welding feasibility, and ultimately decide the repaired original mount offers a balance of strength, cost, and compatibility with the car’s existing systems. The build proceeds with precise machining, heat treatment, and a cardboard infill strategy to reinforce the casting, aiming to keep the repaired component inside tolerances and ensure reliable operation after assembly. The crew then focuses on rejoining the front and rear halves of the car, executing a careful sequence of installation steps that include bolting, alignment, and torqueing to Bugatti-like standards using external references and tube jigs. The process of reassembling the drivetrain is meticulous: mounting the gearbox to the engine, reconnecting all electrical connectors, OBP lines, and oil feeds, and verifying the fit of the now repaired components before the initial startup attempt. Once the mechanicals are in place, they address exhaust changes via a one-off Valvetronic exhaust design built specifically for this car, testing fitment, tone, and flow dynamics. The moment of truth arrives when they attempt to start the engine and bring the chassis up to temperature, encountering fuel line leaks and car vertical checks on the salvage title, which influence their testing plan and expectations. Despite setbacks, the team demonstrates resilience, performing brake bleeding, fuel system adjustments, and a cautious roadway start to evaluate drivetrain response, final assembly integrity, and system communication across the ECU and CAN bus. In the end, the car starts, drives in gear, and the crew reflects on the challenge, the exhaust’s tonal character, and the implications of a salvage title for potential buyers, all while acknowledging that further testing and refinements remain for stage two of the project.
