The “Power-By-Victor” BLACK EDITION® V Engine Overhaul is
designed for the pilot who demands the maximum operating potential from their engine without sacrificing safety or reliability. The benefits of the Black Edition® V engine are improved safety, enhanced reliability, proven endurance, maximum performance and added aircraft value.
Black Edition® V Engines are built by the industries finest craftsmen and include Victor Aviation's FAA accepted and unique "Power-By-Victor" Black Edition® V special engine overhaul processes.
Victor Aviation is proud that they have improved quality and performance standards in the industry and always stays one step ahead of the imitators.
No other aircraft engine supplier can match the added value of a “Power-By-Victor” Black Edition® V engine or our consistent reputation for superior quality, improved engine performance and worldwide customer support.
Volumetric efficiency testing measures airflow into each cylinder and allows Victor Aviation to match cylinders for maximum power so that the pilot can have the benefit of using all available power uniformly and efficiently with all cylinders. With this F.A.A. accepted process of polishing and removal of surface flashings of the intake and exhaust systems, a significant improvement in volumetric efficiency is available.
After cylinders are volumetrically balanced all cylinders produce uniform airflow to provide for improved uniformity of power distribution. Air flow balancing is performed at multiple valve lift openings to assure for the best in engine fuel efficiency. Such precision tests are virtually unique in the aircraft industry to “Power-By-Victor” Black Edition® V Engines.
This F.A.A. accepted process is a dry organic compound coating in which electro statically charged particles of special resins and pigments are applied onto the crankcase, sub-assemblies, intake system, housings and related components. The engine’s crankcase and components are meticulously prepared, pre-assembled by Victor’s technicians, then heated and degassed in preparation for powder coat application. Then the positive charged particles are pneumatically sprayed and adhere to the negatively charged part’s surfaces and finish baked in a curing oven at 400 degrees Fahrenheit to form an extremely tough durable surface. In effect this fuses the premium formulated powder to the components filling the rough, porous surfaces to prevent aluminum oxide corrosion, reduces surface fatigue cracking and improves heat emissivity.
Extracting maximum performance from the valve train is essential for best power, smoothness and longevity.
As an engine’s valves open and close, the contact angle between the valve and the rocker arm becomes critical to proper valve operation and engine performance.
Any valve side loading can decrease cylinder efficiency and reduce available horsepower. Victor’s Black Edition® V Engines are precision machined for minimum valve side loading for better power, performance and reliability. To help achieve consistency, valve spring pressures and heights are matched for more efficient engine operation. The hydraulic lifters and camshaft are matched for identical bleed down rate timing to assure uniformity of independent valve overlap and maximum throttle response.
Engine thrust may be increased by reducing the amount of power wasted in attempting to offset counterbalancing forces induced by out-of-balance internal components. Improving parts balance allows the engine to deliver more power to the propeller and the engine becomes more efficient with less wear on internal moving parts. “Power-By-Victor” Black Edition V Engines are uniquely real-time motion balanced by Victor’s A.S.E certified master machinists to within one gram.
With this F.A.A. accepted process, individual parts and cumulative reciprocating mass weights are balanced, to provide for the best longevity and smoothness of the engine. Balancing not only improves thrust but also reduces pilot and passenger fatigue by lowering the amplitude of various vibration frequencies generated by the engine.
Internal engine parts are very sensitive to the effects of corrosion which can cause premature failure of the engines camshaft, hydraulic lifters and gears. Iron manganese phosphate coating is a F.A.A. accepted process of acid etching a lubricant into steel parts to reduce friction, provide for corrosion protection while improving fuel efficiency. When new parts are installed in an engine there are initial contact surface break-in effects.
Phosphate coating will assure a smooth initial contact break-in effect and also improve parts pitting fatigue life. Friction is reduced by the smoothing of the asperities of the mating gear surfaces and aids in keeping the gear tooth surface shape. This chemical conversion treatment forms a crystalline coated surface which provides for a significant improvement in contact fatigue strength and can greatly improve engine parts life.
Internal engine components move at varying rates of motion and produce different frequencies. These components can be individually revealed by plotting vibration amplitude against frequency. The breaking down of vibration signals into individual frequency components is called frequency analysis, a technique which may be considered the cornerstone of diagnostic vibration measurements. Using a full domain frequency analyzer the frequency and amplitude of a components vibration level can be detected using a tri-axial piezoelectric accelerometer. This F.A.A. accepted testing process enables Victor’s technicians to not only test for complete engine balance but isolate exactly what internal engine components are in need of correction. This level of engine vibration analysis by far exceeds industry standards and enables Victor's technicians to identify engine design and component problems allowing for a smoother running engine.
Crankcases are straightened, then precision milled and final machine bored utilizing precision boring equipment to assure proper alignment and size.
The journals are also finish tested for size and journal geometry by airflow differential procedures to assure a precision fit of the bearings to crankcase halves. This procedure minimizes piston side loading, reduces bearing wear and provides equal loading on crankshaft main journals.
This line boring process reestablishes the centerline of the crankshaft axis, thereby insuring the centerline is parallel and equidistant to the cylinder deck planes for enhanced engine performance.
Engine testing at Victor Aviation is the most extensive procedure used in the industry and performed over a several day cycle process. Victor’s state-of-the-art mobile engine testing apparatus, incorporates a thrust velocity load cell that measures the actual thrust force of the propeller. Engines are installed into a hydraulically activated engine mount, with engine accessories, induction system and exhaust system installed, to simulate real-time engine test parameters.
Using an electronic load cell wafer, the engine’s real-time thrust velocity is recorded at all engine speeds.
During the test process special dyes are put into the oil system and examined under a black light canopy to detect for any discrepancies. Engines are tested at maximum power and must meet Victor’s rigid test standards assuring the highest level of quality control.
A hydraulic valve lifter is a device that converts the rotary motion of the lobes of the camshaft to linear motion to actuate the engines valves while taking up the slack in the valve train.
Valve train clearances change with temperature as the engine heats up and cools down, so the hydraulic lifters have to constantly compensate for thermal expansion of the crankcase, cylinders, pushrods, valves and other valve train components.
By the precision matching of hydraulic lifters with identical bleed down rates to a properly profiled and matched camshaft assembly, Victor's technicians can assure uniformity of independent valve overlap timing and maximum throttle response. This allows for smoother engine operation, improved fuel efficiency and increased engine performance.
Precision machining and matching piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper ring selection for the intended use and diamond cutting machining procedures when gapping your rings.
Piston ring sets come pre-gapped from the parts manufacturer and are not matched to precision fit a cylinder bore. That simply isn't precise enough where gaps should be accurate to within 0.001 inch or less for best engine power.
Victor's technicians precision match piston rings to each individual cylinder bore using highly specialized diamond cutting and finishing techniques to close tolerances. This process assures better cylinder compression and enhanced cylinder performance.
