The SLR is one of the most unique and exclusive vehicles Mercedes has produced in recent times. Through meticulous engineering and testing, Weistec Engineering, the leader in Mercedes aftermarket performance, has created a system that cannot be matched. We at Weistec understood and respected the rich history of the SLR and only sought out to enhance the supercars driving experience. Watch the film to see the creation of our inspiration and design come to life with the unbelievable power gains given by Weistec. WEISTEC SLR BITURBO SYSTEM FEATURE FILM Our top engineers have spent a substantial number of hours designing and developing the most powerful SLR system on the planet. The goal was simple; a complete system providing consistent and usable power without sacrifice. The factory supercharger system is replaced with a massive water to air intercooler, which works in conjunction with the factory SLR intercoolers, to provide maximum cooling and ensure consistency in power. Only the highest quality materials and over 800 individual components were used to create the Weistec SLR BiTurbo System, including Inconel Steel, Stainless Steel, and Aircraft Grade Aluminum. To ensure longevity and the highest performance possible, Ball Bearing Turbochargers with Billet Compressor Wheels are standard.
