Miata power fanatics can rejoice, “IT” has arrived. Moss Motors' MP62 based supercharger system was designed for the Miata enthusiast that wants to make serious horsepower and torque with plenty of room available for significant upgrades in power. The entire system is designed around the Eaton MP62 Supercharger. The MP62 is a roots-type positive displacement blower that delivers instant boost at any RPM. Integrated into the MP62 supercharger is a boost bypass valve. When cruising, the bypass valve opens and re-circulates the air. This allows for fuel economy similar to stock. Put the hammer down and the bypass valve shuts immediately delivering instant boost to your Miata's engine. Every part in this system, including the Eaton supercharger, is warranted by Moss Motors for two years from the date of purchase. Fuel enrichment under boost is provided by the PowerCard Pro. Moss Motors and Dobeck Performance have spent the last several years working together to create the most compact and very powerful - PowerCard Pro. The philosophy is simple, work in harmony with the factory ECU and simply add fuel where necessary only under boost. This philosophy will quickly emerge the first time you drive your newly MP62 supercharged Miata. Instant boost, seamless power and no driveability quirks. A steady idle and nothing but a smooth delivery of boosted power that only the PC Pro can deliver. Another great PC Pro feature is real time fuel curve manipulation. Vast adjustment is available by simply targeting the appropriate zone and making a few clicks on the easy to use push button interface. Additional System Features: Newly Designed Belt Tensioner - Our newly engineered belt tensioner has better geometry and more range of adjustment. The base plate is 3/8" thick aluminum and uses an M10 tensioner bolt to eliminate flexing and belt movement. The all new idler pulleys are designed with a crown. The crowned design causes the drive belt to track in the center of the pulley, not to one side or the other. PowerCard Pro - PowerCard Pro is a load-based tuning solution combining the power of an ultra fast microprocessor and self-diagnostics. Under normal driving conditions PowerCard waits patiently offline, but mash the throttle and PowerCard instantly steps up the fuel necessary for boost. The PowerCard Pro gives the end user the ability to finely adjust fuel, if desired, in the three key areas of Cruise, Mild acceleration and Full throttle. This fine level of adjustment will allow you to tailor the fuel specifically to your Miata's set up. Timing Controller by PowerCard - PowerCard's Timing Controller represents the latest in engine timing technology. As the OEMs upgrade and improve their engine management systems to comply with higher emissions standards, the timing control method for forced induction systems must improve for safe and powerful results. Timing Controller’s RPM based methodology is the answer. 94-97 Miatas with Cruise Control will need to buy the cruise control relocation bracket.
