What it is like to own a three rotor RX-7
Most surviving Mazda Rx-7s are twin rotor engines with a large turbo bolted onto the side of it. Here, Rob Dahm, a lad has found a three rotor engine from the Mazda Eunos Cosmo which was considered as a 2+2 coupe used mainly for cruising.
It was, and still is the only production car to have a three rotor engine. The 20B as it is known in inner circles, has a displacement of 2 litres producing 296 bhp with its twin turbo set up.
In this RX-7, he has bolted a massive turbo charger on and it is releasing around 590 bhp. The guy explains how the engine works and the set up of the car, then listen to it when the turbo spools.
