What you see here is the Mazzei Formula Five—or, to be precise, the Mazzei Formula Five. This unique supercar was created by David Mazzei, merging a Superlite SL-C kit car body with a custom-built five-rotor engine. Attached to this engine is a 106-millimeter Garret G57-3000 turbocharger, and as anticipated, it produces some astonishing sounds. Remarkably, it also generates 1,120 wheel horsepower on the dynamometer. Incredible.
Mazzei has been working on this car for quite a while. He mentioned back in 2021 his intention to develop a five-rotor engine for this project, and he has certainly fulfilled that commitment. His background in car building includes installing a four-rotor in an FD RX-7, so he was well-prepared to create a powerhouse like the Formula Five.
Along with running a 106mm turbo, the peripheral-port five-rotor features billet housings and a six-stage dry sump oiling system. The exhaust is insulated with inconel, and surprisingly, it utilizes Vibrant titanium race mufflers. I can hardly imagine how loud it must be.
All that power from the boosted 3.3-liter engine is transmitted to the rear wheels via a pneumatic Holinger MXT sequential transaxle. You’ll definitely notice this as you hear it flat-shifting on the dyno. A Tilton twin-plate clutch is adapted for this custom setup, and considering the Formula Five produces 806 lb-ft of torque—an impressive figure, rotary or otherwise—this clutch seems quite robust.
What’s even more astonishing is that the dyno run achieved 1,120 hp at the wheels with only 12.5 psi of boost. That enormous turbo is clearly capable of producing more power, and Mazzei himself acknowledges that they could increase the boost to reach 1,500 or 1,600 hp. He explains that during this initial phase of dyno tuning, they are working to improve volumetric efficiency. This issue might stem from the peripheral porting, which allows for greater overlap when both the intake and exhaust ports are open simultaneously, leading to a vacuum. Consequently, the turbo may be reintroducing inert gas, resulting in a decrease in oxygen density.
Even with this inefficiency, the Formula Five manages to achieve one flywheel horsepower per pound, which is remarkable. Take a listen:
This is far beyond anything I would ever attempt to build, but that’s not saying much, as I often feel challenged by my 1966 Ford dump truck. I think I’ll leave the supercar creations to Mazzei.
