The EFR turbochargers for three of Honda Performance Development (HPD)’s projects will be supplied by BorgWarner. These projects are the following: the 2011 ALMS LMP2 engine, the CR-Z Racer and the CR-Z hybrid R concept car. With BorgWarner's technology, the cars’ performance will surely be improved but Honda seeks to keep its fuel consumption at a low level. In a statement, BorgWarner revealed that its new turbochargers use last-generation components, including Gamma TiAl (titanium aluminide) turbine wheels, ceramic ball bearings, stainless steel turbine housings and internal wastegates activated by BorgWarner's compact brushless actuator.
The company revealed that twin EFR turbochargers will be fitted on the 2.8-liter V6 LMP2 engine that will make it to the 2011 American Le Mans Series, European Le Mans Series, 24 Hours of Le Mans, and Intercontinental Cup competitions. In addition, an EFR turbocharger will be installed by BorgWarner and Honda on a race version of the CR-Z equipped with a 1.5-liter engine.But Honda clarified that it will still attempt to maintain fuel efficiency. BorgWarner believes that the overall power can be boosted by 50%, without any support from the hybrid function. If you want to see this for yourself, the final project can be viewed live in the 25 Hours of Thunderhill from December 3 to 5.
"BorgWarner's EFR turbocharging technology delivers increased thrust capacity, quicker boost response, greater efficiency and improved durability—everything professional race car drivers desire," said Roger Wood, Executive Vice President, BorgWarner. "BorgWarner is pleased to collaborate with Honda Performance Development to put our advanced technologies to the test in the one of the most challenging environments: on the race track."
