Todd Budde’s AWD Mazda RX-7 gained a lot of attention when it debuted at SEMA 2019. Since then he’s been refining the car and twin-turbo 26B four-rotor built by Billet Pro. Todd took the RX-7 to Motorvation Motorsports for a dyno tune with David Mazzei from Mazzei Formula. While there the twin-turbo 26B four-rotor made 1,187 horsepower and 779 lb-ft of torque on 28 psi of boost from two Garrett G42-1200 turbochargers and a Haltech Nexus R5 ECU.
