World Challenge Turbochargers

GMG World Challenge turbos are modified BorgWarner VTG turbos,  featuring larger CNC machined  compressor wheels made of high strength forged aluminum, allowing for higher flow-rates and rotational speeds while safely operating under higher temperatures.  These upgraded VTG turbos are a key component of the GMG World Challenge package for turbocharged Porsche cars and are specifically tuned to the design characteristics of the WC intercoolers, WC GT exhaust systems, and proprietary GIAC software.  This integrated system, in combination with the WC suspension upgrades, create the perfectly balanced World Challenge Porsche road car.
