This Angry Four-Rotor RX-7 Dyno Run Has A Racing Car Soundtrack

The dyno run video of David Mazzei's incredible RX-7 includes flames and Mazda 787B-like noises

We’ve covered Rob Dahm’s astonishing three-rotor Mazda RX-7 a few times before, but the man’s latest video focuses on someone else’s FD. And we just can’t get enough of the noise it makes.

David Mazzei’s RX-7 is powered by a custom-built four-rotor engine, and a big driving force behind the project is the urge to recreate the sound of the legendary Mazda 787B prototype racer. The first and only rotary-powered car to win the 24 Hours of Le Mans emits an addictive shriek we’re unlikely to hear in the motorsport world ever again, and this FD is deliciously close to replicating that soundtrack.

Unlike the naturally-aspirated 787 engines, Mazzei’s four-rotor is fed by a GTX5533R 98mm Garrett turbocharger. Inevitably, then, there are plenty of whistles and chattering you wouldn’t have heard from the 787, but all those turbo noises merely add drama to the wail of the four-rotor.

The engine is extremely potent, too, clocking 950hp on the final run in the video. And apparently, there’s even more to come…

These babies are swaps themselves, sadly. and an LS can be much cheaper to source as well as easier to build in the US. So yeah, that is the gist of the redneck swap.

One is the exhaust, one is the wastegate dump from the turbo

My guess would be because of the possibility of restictions in the exhaust flow if it only runs a single exhaust

There is a turbo waste gate, a side exit un-restricted exhaust and a rear exhaust (without knowing and purely guessing) i would say due to state restriction the rear exhaust is a full exhaust so it can be driven i the road but he can open up the side exhaust for more and better power as its less restrictive and the turbo waste gate is just to control boost pressure

I love how it shoots fire out of three exhausts.
