Ordering Considerations – What We’ll Confirm

To ensure your TSIO-550-G engine is properly configured for installation in your Mooney, we will confirm the following during the quoting process:

• Aircraft Model: Is your aircraft an M20TN Acclaim or Acclaim Type S? There may be differences in engine mounts, sensors, and cowl clearance.
• Electrical System: Confirm 12-volt or 24-volt compatibility. Most M20TN aircraft are 28V (24V nominal), but older retrofits may vary.
• Turbo Integration: Ensure compatibility with Mooney’s certified turbo and intercooler system layout, including oil return and wastegate plumbing.
• Air Conditioning or Optional Drives: If your aircraft includes A/C or other belt-driven accessories, we will verify accessory case provisioning.

Mooney-Engineered Speed

The TSIO-550-G is optimized for high-speed cruise in the flight levels. With its smooth power delivery, low RPM operation (2500 max), and efficient turbocharging system, it helps the M20TN Acclaim consistently cruise at 220+ KTAS while maintaining fuel efficiency and reliability over long distances.
