Rotary 20B turbo Mazda RX-7 - Promaz Automotive

Charles’ Promaz Mazda FD RX-7 runs a personal best pass at Heathcote. The triple rotor stock import engine sounds great and certainly spices things up. Boost comes from a Garrett GTX42R turbo on just 13psi boost, MicroTech LX12 computer running on regular pump 98-octane unleaded. The drive-line still remains factory RX-7 issue and on the day saw Charles break not only a gearbox but also a driveshaft. [ ]. Heathcote Park Raceway, Australia - May 12th 2013.
