Documented Test Reports

Every unit ships with a test report. Your team can verify performance data before installation.

Pre-Installation SOP

Standardized checklists reduce installation errors and protect warranty activation in your market.

Fumigation-Free Packaging

Rust-proof, impact-resistant wooden crates engineered for international sea freight.

End-to-End Verification

100% Inspection Process

Every unit passes through a multi-stage quality gate before it's cleared for shipment. No exceptions.

Step 01

Incoming Inspection

Raw materials and core components verified against OEM specs before entering production.

Dimensional tolerance check
Material certification review
Step 02

CNC Machining QC

In-process checks at each CNC station ensure tolerances are maintained throughout production.

Bore & surface finish check
Valve seat & guide precision
Step 03

Performance Testing

The critical gate. 100% of units undergo Dyno/Vacuum testing — no sampling, no exceptions.

Vacuum Test Cyl Heads
Step 04

Final Clearance

Passed units are issued a report, rust-proofed, and packed in fumigation-free crates for shipment.

Sea-freight crating

Dyno Testing

Bare Engines

Each engine runs through a cold-start cycle followed by a hot-load cycle on the dynamometer. We measure oil pressure, coolant temperature, RPM stability, and power output — all logged to the unit's test report.

Cold Run
No-load startup & idle
Hot Run
Load cycle & thermals

Vacuum Testing

Cylinder Heads

Every cylinder head is pressure-tested under vacuum to verify valve seat integrity and combustion chamber sealing. Any micro-leak fails the unit — no exceptions. Results are documented per head.
