Vantage Engine

More features. More Benefits. More Value. More reasons to put your trust in Superior's Vantage Engine.

The components used to create Superior’s FAA certificated Vantage Engine are the culmination of literally hundreds of individual design and manufacturing improvements we have made to our array of FAA PMA-approved parts and components over the last 40-plus years. 

Today, the fit, finish and quality of all the parts and components used in Superior's engines are of the highest possible quality and consistency. All of our aluminum parts (crankcases, sump, housings, etc.) are Alodine treated for corrosion protection. But, unlike other engine companies we do not paint these parts (unless custom ordered), we only paint the steel cylinder barrels. Why? The reason is simple: we have the best looking parts in the business and we don’t have to cover up flaws with paint.

The result is better looking engine that is lighter and easier to inspect. 

The obvious quality of the Vantage Engine is just the beginning of the many quality and performance advancements it brings to piston-powered, general aviation aircraft. 

Other examples of the Vantage’s many standard features and benefits include: 

Reinforced Crankcase

SUPERIOR_CRANK_CASE.jpg

SAP_Mark_2C_Icon.jpg Direct lubrication to the thrust face greatly reduces crankcase and crankshaft wear

SAP_Mark_2C_Icon.jpg Balanced oil system provides uniform lubrication to both sides of the crankshaft and camshaft. This reduces pressure fluctuations while equalizing oil-flow through the entire engine, including the filter

SAP_Mark_2C_Icon.jpg Reinforced cylinder deck strengthens areas against crankcase pressure and helps eliminate cracking

SAP_Mark_2C_Icon.jpg Precision machining to accommodate cooling nozzles for high-compression piston and turbocharger applications.

SAP_Mark_2C_Icon.jpg Proprietary ESR Crankshaft

SUPERIOR_CRANK_SHAFT.jpeg

SAP_Mark_2C_Icon.jpg Electro Slag Remelt (ESR) process removes many more metal impurities than the standard Vacuum Arch Remelt (VAR) process used in the production of most prior-generation crankshafts

SAP_Mark_2C_Icon.jpg Oil journals are polished and coated to virtually eliminate the corrosion and pitting issues that were prevalent in many VAR produced crankshafts

SAP_Mark_2C_Icon.jpg Each crankshaft is balanced within exacting tolerances to ensure the smoothest engine operation throughout the power operating range.

SAP_Mark_2C_Icon.jpg High-flow oil sump

SAP_Mark_2C_Icon.jpg Smoother intake manifold and plenum reduces aerodynamic turbulence for better breathing for all four cylinders

SAP_Mark_2C_Icon.jpg Unique plenum turbulator improves air-fuel mixing

SAP_Mark_2C_Icon.jpg Tuned intake tubes balance the intake runner length to further improve airflow and engine breathing

SAP_Mark_2C_Icon.jpg Polished, stainless steel tubes minimize rust and corrosion.

Millennium Cylinders

MILLENNUIM_360_CYLINDER.jpeg

SAP_Mark_2C_Icon.jpg Through hardened steel barrel provides uniform hardness all the way through the barrel walls, ensuring even wear while withstanding extreme temperature and pressures

SAP_Mark_2C_Icon.jpg Very high quality casting creates aerodynamically better surfaces to improve overall airflow and cooling

SAP_Mark_2C_Icon.jpg Exhaust and intake ports are volumetrically matched for maximum output and performance

SAP_Mark_2C_Icon.jpg Computer-generated head fin configuration for more efficient heat transfer and fewer “hot” spots

SAP_Mark_2C_Icon.jpg Increased port wall thickness eliminates issues with warping and cracking

SAP_Mark_2C_Icon.jpg Manufactured from the most advanced alloys available to exceed industry standards for strength and porosity.

Computer Optimized Camshafts

camshaft_1.jpg

SAP_Mark_2C_Icon.jpg Superior’s camshaft is designed for better cruise economy, lower valve-train loads and smoother idle and power operation

SAP_Mark_2C_Icon.jpg Lower valve-train loads reduce camshaft and lifter spalling while decreasing wear and friction to the valve-train and guide

SAP_Mark_2C_Icon.jpg Precisely timed camshaft lobe valve events eliminate re-ingestion of exhaust gasses, improving economy and overall performance

SAP_Mark_2C_Icon.jpg Idle and power vibration characteristics are also computer optimized to “passenger car” standards to reduce vibration, pilot fatigue and component wear.

Connecting Rods

connecting_rods_1.jpg

SAP_Mark_2C_Icon.jpg Precision machining of the entire connecting rod surface a better finish and more consistent weight and balance

SAP_Mark_2C_Icon.jpg Forged VAR 8740 steel per AMS 6325

SAP_Mark_2C_Icon.jpg Individual connecting rods are statically and dynamically balanced

SAP_Mark_2C_Icon.jpg Tongue and groove design reduces shear loads.

Component Balancing and Matching

SAP_Mark_2C_Icon.jpg Connecting rods are individually statically and dynamically balanced

SAP_Mark_2C_Icon.jpg Crankshafts are balanced to within .25 ounce-inch

SAP_Mark_2C_Icon.jpg Connecting rods, pistons, piston pins, connecting rods and bolts are all weighed and balanced as a set to closely match the weights of all opposing components results in smoother engine operation.

Tri-Metal Bearings

SAP_Mark_2C_Icon.jpg Tri-Metal Bearings are 40% stronger than conventional aluminum bearings.  

Superior’s Machined Parts versus the competition’s cast parts.

Superior has elevated the production of many seemingly simple parts to a higher art form. For example, instead of using lower cost and quality processes including casting and painted, or plastic (filler tube) processes, and materials like our competitors, we have machine numerous parts from billets and then alodine these parts against corrosion. 

Superior billet-machined parts include:

SAP_Mark_2C_Icon.jpg Oil filler tube and level gauge

SAP_Mark_2C_Icon.jpg Vacuum pump drive

SAP_Mark_2C_Icon.jpg Oil filter adapter

SAP_Mark_2C_Icon.jpg Prop-governor drive
