Designed for Speed and Altitude

The TSIO-550-B is engineered for aircraft that fly faster, higher, and longer. The dual turbochargers maintain sea-level power well into the flight levels, making it ideal for pressurized or high-cruise-performance airframes like the Lancair IV. The engine is compatible with advanced experimental cooling systems and aftermarket turbo controls when integrated properly.

Ordering Considerations

When ordering a TSIO-550-B, we will confirm the following:

• New or Rebuilt: Available in both factory new and factory rebuilt options, each with full warranty support.
• Turbo and intercooler compatibility: Required if using custom ducting or modified airframes (Lancair-specific cowling kits, etc.).
• Electrical system: Confirm 12V or 24V starter and alternator system compatibility.
• Accessory case provisions: For custom avionics, air conditioning, or dual alternator requirements, we can assist with spec configuration.

Trusted in High-Performance Experimentals

The TSIO-550-B has been the go-to choice for Lancair builders seeking the best power-to-weight ratio and maximum cruise performance. With the right cooling and installation support, this engine is capable of 250+ KTAS cruise speeds at FL240 in properly tuned airframes.
