Mazda RX-7 with a Twin-Turbo 26B Four-Rotor Screaming on the Dyno

Todd Budde from F3 Motorsports (ForceFedFab) built a unique Mazda RX-7. In the engine bay sits a 2.6 L 26B four-rotor built by Billet Pro with billet plates, peripheral porting, JMF billet intake, and two Garrett G43-1200 turbochargers. The motor is paired to an AWD drivetrain and Graziano six-speed transaxle from a Lamborghini Gallardo. The drivetrain sends about 70% power to the rear and 30% to the front. The motor made 1,182 hp (873 kW) and 779 lb-ft (1056 Nm) of torque on the dyno in 2021. Todd recently visited the dyno again for a tune which you can listen to in the video below. Otherwise read the detailed specs on this unique car in Motortrend’s article.
