BorgWarner's 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, as the company said in a statement.
First of all, twin EFR turbochargers will be installed on the 2.8-liter V6 LMP2 engine that will be used in the 2011 American Le Mans Series, European Le Mans Series, 24 Hours of Le Mans, and Intercontinental Cup competitions.
Second of all, BorgWarner and Honda will install an EFR turbocharger on a race version of the CR-Z equipped with a 1.5-liter engine, but the Japanese manufacturer will also pay special attention to fuel efficiency. BorgWarner says that the overall power will be increased by 50 percent, without support from the hybrid function. The final project can be seen live between December 3rd - 5th, in the 25 Hours of Thunderhill.
"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."
