The Shakedown Period

---

Congratulations on the delivery of your newly engineered vehicle. Every vehicle we build undergoes rigorous in-house testing, but a custom, high-performance conversion behaves differently than a factory-standard vehicle.

The first 800 to 1,500 kilometers are a critical "shakedown" period. As brand-new components settle and heat-cycle together for the first time under real-world driving conditions, minor teething adjustments are entirely normal and expected.

When integrating advanced powerplants into different chassis, components from different manufacturers must work in perfect unison. During the initial settling phase, you may encounter:

• Thermal Expansion & Fluid Seepage: New gaskets, seals, and custom hose fittings will expand and contract as they heat-cycle. A minor drip or seepage can occur as clamps and fittings settle, often simply requiring a quick re-torque.
• NVH & Harmonics: High-performance engine mounts, heavy-duty drivelines, and altered drivetrain geometry alter the vehicle’s NVH (Noise, Vibration, Harshness) profile. Some feedback is a natural characteristic of performance hardware; others may require minor alignment shims as components seat.
• Sensor & ECU Calibration: Integrating modern engine electronics into older platforms relies on highly specialized standalone or adapted wiring. As the ECU learns its new environment, exhaust flow, and fuel maps, non-critical sensor calibrations may occasionally trigger a temporary warning light.
• Fastener Settlement: Heavy-duty suspension components, chassis components, and engine mounts settle under load. It is vital to check the torque on critical fasteners (especially engine mounts, custom brackets, and driveshaft bolts) after the first 150 kilometers.

To protect the longevity and engineering integrity of your build, you must follow this strict break-in protocol:

1. The Engine Bay Inspection: For the first month, pop the hood after every drive. Actively inspect the engine bay for any signs of component rubbing (hoses near pulleys) or thermal exposure (wiring harnesses too close to exhaust components).
2. Establish a Baseline: Closely monitor your custom digital or analog gauges. Learn what operating temperatures and pressures are "normal" for your specific configuration, as custom high-performance cooling systems cycle differently than OEM setups.
3. The Thermal Smell Test: A precision conversion should never smell of raw fuel, burning oil, or acrid electrical heat. If you detect any unusual thermal odors, pull over safely and inspect the vehicle immediately.
4. Initial Flush & Oil Service: We strictly recommend dropping the engine oil and replacing the filter at the 800-kilometer mark to flush out assembly lubricants and any microscopic bed-in debris from the build process.

While minor fluid adjustments can easily be sorted at your first scheduled post-build inspection, critical symptoms should never be ignored. Stop driving and contact the workshop immediately if you experience:

• A sudden drop or fluctuation in oil pressure.
• A significant or sudden loss of engine power.
• Any persistent, harsh, or internal "mechanical" knocking sounds.

A Final Note: A high-performance custom vehicle is a specialized piece of engineering. Staying proactive and attentive during these first few weeks ensures you have a bulletproof, ultra-reliable machine for years to come.
