The STS (Superior Turbine Strike) turbine wheel. It will take a shorter time (decrease 5-8%) to build a boost and, at higher RPM, prevent choking easier because it's less inertia and restrictive than an 11 or 12 blades turbine. The STS Advanced ceramic dual ball bearing technology improves the response speed (time needed to build boost) 10-15% as well as being more durable due to the improved shaft dynamics control. The increased power comes from the enhanced design. It utilizes an inner and outer race with rollers or balls between the two races. The inner race is pressed onto the turbo shaft, and the outer race is pressed into the CHRA. The rollers or balls replace the oil’s “job” of controlling the turbo shaft’s orientation but do still need to be lubricated.
