The RX-792P effort was full steam ahead for 1993 and the group began to look towards improvements that could be made the chassis. On IMSA’s sliding weight vs. engine displacement scale, the Mazda 4-rotor came in at and many teams had cause for concern about this, thinking that the Mazda engine had been gifted a power-to-weight ratio advantage. While the RX-792P showed occasional turns of speed, the reality was that the engine simply was giving up far too much horsepower to its competitors, thus making the perceived power-to-weight bias within the regulations just that, a perception and not a reality. Also, any advantage that might have been was certainly offset for the need to cool the car and the corresponding drag relative to power output.
