ESS Tuning E60 M5 and E63 M6 S85 V10 supercharger kit to start at $11,995 for the VT1, $15,995 for the VT2
ESS Tuning revealed their S85 V10 supercharger kit at Bimmerfest 2011. They handed out flyers with details showing the pricing information as well as dynos of the kits. It is difficult to see the graphs but they are claiming about 560 rear wheel horsepower for the VT2 at 6 psi at a price of $15,995 and in the 530 whp range for the VT1 at 5 psi for $11,995. Eloy at RPI was wrong about the pricing as he started a rumor about a sub $10k price point
likely to generate interest.
There is a typo in the flyer, torque for the VT1 should be 360 and 365 not in the 4XX range as written:
