Lotus Cars USA has released a factory style supercharger kit for the Lotus Elise and Lotus Exige models that come naturally aspirated. Owners who bought their Lotus Elise or Lotus Exige before this blower kit was available, can now bring their car back to an authorized Lotus dealer and have the car tuning performed. After the kit is installed on the 1.8 liter Toyota engine, performance numbers increase from 189 hp and 133 ft lbs or torque to 218 hp and 155 ft lbs of torque. The new system is warrantied and legal in all 50 states, while also being certified for emissions. The supercharger kit also comes with high flow injectors, ECU recalibration, and a redesigned intake manifold to add the supercharger. Even though torque gains are minimal, the performance numbers now peak at 5,000 rpms instead of 6,800 rpms. Lotus has not yet released pricing for the supercharger kit.
