Designed for high-horsepower engine applications like the BMW S58 and B58, this turbocharger is a gamechanger. A Garrett-powered racer recently made history, becoming the first BMW M Sedan to break into the 7-second range with a 7.964-second pass at 176.71 MPH in the 1/4 mile. The team didn’t stop there, recently improving their performance with a 7.805-second pass at 181 MPH.
On the dyno, the Garrett G-Series G45-1475 turbocharger delivered an impressive 1500 AWHP and 1390 AWTQ with a 1.01 A/R turbine housing (see dynograph below). The BMW G8X, equipped with this turbocharger, features a highly modified setup, including a Pure Drivetrain Solutions drivetrain and an RK Autowerks 3.4L stroker engine kit, among other performance enhancements
G45 Turbine Housing Kits
G45 turbine housing kits are available in four A/R. 1.01 A/R | 1.15 A/R | 1.28 A/R | 1.44 A/R stainless steel housings with T4 divided inlet flange. Our 1.44 A/R T4 turbine housing flows 57 LBS/MIN of air which is a 14% increase over the GTX45 turbine wheel.
