Garrett Turbocharger 856800-5001S, part of the GTX Gen II Series, features a redesigned billet aluminum compressor wheel using advanced CFD-based Honeywell simulation to optimize flow and efficiency. This updated design increases mass airflow and delivers up to 20% more horsepower compared to earlier versions, providing greater tuning flexibility and a broader power range. Built for high-performance applications, it includes a ported shroud compressor housing to reduce surge and ensure consistent boost across the power band. The turbocharger also uses a dual ceramic ball bearing system for improved shaft stability and durability, while the water-cooled center housing helps manage operating temperatures. Its turbine wheel is made from Inconel, a high-strength superalloy that resists heat fatigue under extreme exhaust conditions. Designed for enthusiasts demanding reliable power and thermal efficiency, this unit supports high-output builds with both performance and longevity in mind.
