RX8 performance upgrades

Rather than persist with the factory 13B 2-rotor Renesis engine the Promaz team has installed a 20B 3-rotor engine using a turbo race port.

Here's another late model Mazda using and older style rotary engine this time in the way of a 13B twin rotor Cosmo engine.

Promaz bridge ported 20B triple rotor engine and boosted by a Garrett GTX42R turbo running on methanol fuel and backed by a Jerico 5-speed gearbox.

Promaz Dyno Day - October 2014

We had a great turnout at out recent dyno day. With trophies for rotary, 4, 6 and V8 powered cars it was Nigel's VL Commodore turbo who took outright power for the day with a stunning 746kW dyno run.

We would like to thank everyone who attended as well as Promaz team for their hard work on the day.

Armando from Energia Australia was also on hand to show the benefits of Oxy-Hydrogen decarbonisation demonstrations in rotary engines. 

Special thanks to our sponsors:

MicroTech, Turbosmart, Penrite, Repco, FullBOOST and Paul from Boostronics.
