 ??  ?? pev­ery year it seems Gar­rett pushes the bar higher on large-frame tur­bocharg­ers. 2019 was no dif­fer­ent thanks to the un­veil­ing of its G57, a charger of­fered with your choice of an 88mm, 94mm, 98mm, 102mm, or 106mm com­pres­sor wheel (in­ducer). The G57 in­cor­po­rates a ground­break­ing one-piece alu­minum cen­ter hous­ing and back­plate to save weight, and the new 118mm In­conel tur­bine wheel hang­ing off the other end of the shaft flows 19-per­cent more than the wheel used in its GTX Gen II equiv­a­lent.
