Utilizing a brand new proprietary production process and totally new steel compound, Superior 's engineers have created the ESR crankshaft – the most technically advanced crankshaft available for the four-cylinder engine market. Superior 's proprietary Electro Slag Remelt (ESR) process removes many more metal impurities than the VAR process. Superior 's ESR process combined with the new higher alloy content steel creates a crankshaft that is stronger and will resist many of the problems found in crankshafts produced through older technology processes. The new ESR crankshafts are exclusively crafted for Superior Air Parts by Thielert Aircraft Engines, of Hamburg , Germany . Superior using the new ESR crankshaft as the standard crankshaft in the XP-360 Engine.
The camshaft 'brain' of your XP-360 engine is designed for better cruise economy, lower valve-train loads, and smoother idle and power operation. The camshaft intake and exhaust valve lobes have been computer optimized. Lower valve-train loads reduce camshaft and lifter spalling and decrease valve-train and guide wear and friction. Precisely timed camshaft lobe valve events reduce re-ingestion of exhaust gases and improve economy and overall performance. Idle and power vibration characteristics are also computer optimized to passenger car standards to reduce pilot fatigue and component wear. ·
The crankcase is made from aerospace grade AA C355-T71 stabilized structural aluminum alloy per AMS 4214. The reinforced crankcase cylinder deck greatly reduces deck-to-deck cracking. The balanced oil system lubricates the crankshaft and camshaft from either side of the crankcase. This reduces oil pressure fluctuations and equalizes oil flow through the entire engine, including the lifters. Pressurized oil lubricates the crankcase thrust face, reducing friction on the loaded surface of the case where the crank pulls the case forward. Every crankcase also comes machined to accept piston cooling oil nozzles. ·
Each engine comes with a set of statically balanced connecting rods. These rods are made from precision forged high-strength aerospace grade SAE 8740 forgings per AMS 6325. Consistent precision machining of these forgings and installation as matched-weight sets yield a statically and dynamically balanced rotating section for reduced vibration and wear. But balanced rotating components don't stop there, add in Superior's matched-weight piston sets and you have the most dynamically balanced engine available. ·
The sump is made from aerospace grade AA C355-T71 stabilized structural aluminum alloy per AMS 4214. A smoother intake manifold and plenum system reduces aerodynamic drag for better breathing of all four cylinders, while at the same time a plenum turbulator improves air-fuel mixing. Tuned intake tubes balance the intake air runner length to further improve engine breathing. Polished stainless-steel intake tubes eliminate rusting from the elements and give your engine that special, first-class look.
Of course, you can't go wrong with Superior's legendary Standard-Cast Cylinders with 6% better volumetric efficiency, through-hardened steel barrels, and Superior's bullet-proof head design.
