VMP has spent countless hours developing a lid upgrade that will make real-world differences in power and performance. What the company arrived at was a patent-pending design that improves high-RPM airflow. In turn, airflow limitations of the stock blower are eliminated. Furthermore, the lid is compatible with a variety of intercoolers, including the stock intercooler, VMP’s 81 mm Street Intercooler and VMP’s Apex specific Street and Race Intercooler Upgrades. When coupled with VMP’s intercooler upgrades, it controls the inherently high intake air temperatures common when modifying the stock supercharger.

The lid is packed with additional features. The lid fits under the stock strut-tower brace to maintain a factory-like appearance. The lid features a boost reference port for the most accurate data collection. Additionally, the lid includes eight 1/8th” NPT ports. These ports are for the true horsepower junkie, allowing nitrous or water-methanol direct injection for ultimate horsepower gains. For those GT500 owners looking to go as fast as possible, the lid is 1.5 pounds lighter than the stock lid. The company saw 20 rearwheel horsepower gains with the lid alone, and 40 rearwheel horsepower when the lid was coupled with their upgraded intercooler.
