“Power-By-Victor” Performance - Factory New Engine

Experimental Aircraft Applications
and Part 91 Operations

A Power-By-Victor Gold Edition VII™ Engine is designed for the high performance, experimental aircraft builder or manufacturer who wants the benefits of a zero-time factory engine that will perform like a “Power-By-Victor” engine.

We start by taking a “zero-time” factory new Lycoming or Continental Motors engine and testing the engine in our specially engineered load cell for thrust velocity, vibration harmonics, and complete engine performance characteristics. Using a spectrum analyzer and piezoelectric accelerometers, our technicians can determine the frequencies and amplitudes of internal moving parts to determine real-time parts motion balancing prior to engine disassembly.

The engine is then completely disassembled, inspected and the unique “Power-By-Victor” processes used in Victor’s XR Black Edition® VII Engine,

are applied to the “zero-time” factory new Lycoming or Continental Motors engine.

When we have completed the “Power-By-Victor” engine procedures, the engine is then re-tested in our engine load cell to assure that we have extracted the maximum performance potential from the engine without sacrificing engine reliability or safety. By comparing the incoming and final engine load cell test reports we are able to determine engine performance comparisions.

For experimental aircraft applications, we work closely with the aircraft builder and have several engine performance modifications and processes available.

  Expectations Exceeded

I have invested many hours meticulously building and maintaining my Lancair, so when I needed some engine work, I started looking for an engine shop that would provide the same care and attention to detail. After some searching, I found Victor Aviation. Exceptional workmanship can be difficult to find these days, especially when you are a hard-to-satisfy perfectionist like me.

Victor Aviation exceeded my expectations. My engine is now a work of art.

The pictures are telling, but you really need to see one in person to truly appreciate the craftsmanship. I am looking forward to showing it off at all the air shows I attend.
