World's First Billet Turbo 5-Rotor Engine Dropped Into SLC Superlite

David Mazzei of Mazzei Formula LLC is a rotor-head from way back, with a rich background in rotary engines and tuning. David's current project however, is undeniably one of the most interesting and ambitious projects we've seen in a while. Mazzei's vision? To create the world's first 5-rotor engine, and stuff it into a modified SL-C Superlite kit car.

David got his hands on the early model SL-C from a fellow Rotary enthusiast, David Preece. Tragically, Preece's untimely passing left his dreams of a 3-rotor project unfulfilled. Grasping the baton from where Preece left off, Mazzei traveled from Alabama to San Francisco, purchasing the car from Preece's family with a promise to continue the legacy. 

The build really kicked off in 2021, collaborating closely with Todd Budde from the Rotary engine and fabrication wizards at Forcefedfab in San Antonio. David and his crew have also teamed up with professional IMSA driver Bryan Leonard for testing and tuning of the platform. 

The plan behind the idea encompasses the world's first billet 5 rotor engine, full peripheral port, and a modified g57 turbo for all the boost. The intent? A staggering 1500rwhp and an auditory experience akin to a V10 F1 engine. Thanks to the unique mechanics of the five-rotor engine which fires once every revolution, Mazzei theorizes that at 9k rpm, this engine will resonate with the iconic sound of an F1 V10 revving at 18,000.

Key features will include a water-to-air intercooler plenum intake, three heat exchangers, and two oil coolers. Fuelling this behemoth will be a mechanical fuel pump cable drive, intricately built around a custom bulkhead and tank. As you'd expect, the car will also run a Holinger MXT transmission with geartronic paddleshift. 

While it hasn't fired up just yet, David's most recent posts allude to it getting closer and closer to the day we all get to hear this unreal machine fire up! Check out all the pictures below and David's YouTube videos to stay up to date with the build.
