Logan Carswell enjoys racing his special Mazda RX-7 at the track. The car is powered by a 2.6 L “26B” four-rotor built by Logan’s company Defined Autoworks. The motor features a custom peripheral-port, eight injectors, and custom eccentric shaft. It is paired to a SAENZ TT3 six-speed sequential transmission with a Tilton triple-plate clutch and KAAZ 1.5-way limited-slip differential. In the video below Logan was class restricted to 500 whp while racing at Mid-Ohio Sports Car Course in Lexington, Ohio.
