Many people know Mike Whiddett‘s incredible “Madbul” RX-7. We have following since its debut in 2008. What we didn’t realize is we have never featured it. That ends today with Mike debuting the latest version.
Although most of the newest version’s changes are cosmetic, the third generation Mazda RX-7 revolves around a four-rotor 26B built by Pulse Performance Race Engineering. These are the same guys who built the six-rotor monster we have featured before powering a Mazda RX-4.
Mike’s engine features a custom PPRE centre and end plates, custom chrome-moly crank, lightened and balanced high-compression RX-8 13B-MSP Renesis rotors, and Mazda 3mm seals. All this is good for 538 whp and a rev limit at 10,750 rpm. After receiving factory sponsorship from Mazda, Mike intends on building another motor with “major gains.” Does this mean a turbocharged engine? We will have to wait and see.
