Research and Development

Cosworth Technology
Cosworth Technology in cooperation with Grinnall Cars have reworked and re-mapped the Audi motor to give increased power and torque. A full program including engine cooling and air path temperatures, engine bay and radiator temperatures, fuel mapping and programmable ignition settings, drivability and handling have been developed. CT's engine dynos were used for engine calibration followed by circuit testing of different performance levels at Bruntingthorpe proving ground.

The new Grinnall R3T was launched at the BMF Rally in Peterborough on the 21st - 22nd May 2005. For more information, please visit the new Trike R3T section.
