After the success of our turbodrive concept with Toyota (250S) and Honda (330R) engines, using Rotrex centrifugal chargers, we have decided to introduce a concept for Rover engines as well. Unlike other compressor concepts we have left the engine compression ratio at its original level. Instead, we have reduced the boost pressure to 0,35bar. This brings the advantage of reduced effort and costs to disassemble the engine as well as lower charger pressure and temperature. Our experience from the Rover Turbo concepts we built in the past shows us that use of standard piston is uncomplicated The concept further includes an optimized -air intercooler system where the intercooler system is placed in the left side of the engine bay behind the air intake. For customers who prefer using the car on racetracks mainly or in very hot conditions we could offer our water cooled intercooler system, where we locate an intercooler in the engine bay, and a heat exchanger unit in the front of the car . The water-cooled intercooler is more expensive than an air-cooled intercooler, but also three times more effective. The kit can be fitted on Elise 120hp and 160hp Rover engines (Elise 111 / 111S). The indicated performance values relate to 111s.     The conversion consists of:Rotrex centrifugal charger C30 serieschargerbracket Boost hoses siliconeEnlarged alloy throttle body (only 120hp model) Free mapable ECU Wideband Lambda controller Sports camshaft inlet/outlet compressor" (only 120PS models) Airbox System Air intercooler (or water cooled intercooler with heat exchanger at the front of the vehicle)Hoses and electric water pump (if water cooled intercooler is fitted) FittingProgramming of the ECU on the rolling road Power curve  Performance: 212hp at 5900 U/min (VVC Modell) ca. 198hp at 5800U/min (120hp model)Torque: 250Nm at 5080 U/min (VVC Modell) ca. 230Nm at 5200U/min (120hp model) Upgrade Option to water cooled intercooler with heat exchanger in front of the car 1.490Â Â The use of a sports cat and a suitable silencer is required.
