AER designed engine with little basis in AER
P07. Originally designated P41. Designed to accept direct injection from the outset.
In 2010 the original P41
Mazda engine was replaced with the largely new AER P70 engine. The new
engine benefits from a brand new block and cylinder head for increased
power and endurance when used in the ALMS and for the forthcoming ACO
Dyson Racing used the engine during 2010 where
the steadily increasing power made visible gains during the later
stages of the season. For 2011 the engine was extensively
developed to achieve higher speeds and wider power range. Changes
included a new inlet system, pistons, cams and gear train.
For 2012 the MZR-R is designated P80. This engine can rev higher and as such has a wider usuable power band.
