At present, Billet/MFS compressor wheels are popular trend in the turbocharger industry. Many performance turbos and new electronic turbos use MFS/Billet compressor wheels to improve the performance and working intensity of turbochargers . Compared with traditional cast compressor wheel, they are both made from aluminum material. The machining technology is different: common compressor wheel are casted in aluminum water, so the density is low; Billet/MFS Wheel is machined from solid aluminum compressor wheel and is carved from a complete piece of aluminum, which has a higher density and strength, which greatly improves service life and power. Moreover, There are many billet compressor wheel with various colors, red, blue, yellow, etc. have appeared on the market, which greatly enhances the viewing of the turbocharger and is very suitable for brand publicity.
