Mazda 787B, Mazda RX-792P, Mazda RX-7
The 787B and RX-792B both use the 4-rotor R26B an engine that is easily capable of at least 900 HP, but limited for long term racing reliability to 700 HP.
Racing rotary engines are easily one of the loudest Exhausts at idle and arguably the loudest Exhaust note on the track at full song. An incredible engineering feat and incredible engine.

Mazda RX-792P Hot Laps at Mazda Raceway Laguna Seca | Mazda USA
We were up at Mazda Raceway this past weekend and decided to take some of
our favorites out to stretch their legs. We brought an RX-7 GTO, an
RX-792P, and one of the 787s from the '91 Le Mans race.
Pardon the wind noise—we'll get it fixed next time—but this is from the
top of the RX-792P.
