MAZDA RX-7 THIRD GENERATION

MAZDA RX-7 THIRD GENERATION

The RX-7 was an awesome car when it first came out, and only got better with each generation. The third generation was released in 1993, and was the best RX-7 yet. The vehicle was the first ever mass produced sequential twin turbocharger system to be exported from Japan.  The sequential twin turbocharged system, introduced on this series in 1992, was a very complex piece of engineering. The system was composed of two turbochargers, one to provide boost at low RPM. The second unit was on standby until the upper half of the rpm range during full throttle acceleration. The first turbocharger provided 10 psi of boost from 1800 rpm, and the second turbocharger was activated at 4000 rpm and also provided 10 psi. This significantly increased the power output of the vehicle, and forced test drivers to adjust their driving styles so they didn’t understeer the vehicle.
