EFR Turbo Series
The EFR line of turbochargers was born out of an internal BorgWarner Turbo Systems program
labeled Advanced Aftermarket Products or AAP.
The program was engineered by a cross-functional team that began with the proverbial
clean-sheet of paper. No legacy products, no preconceived notions of what
a turbocharger could or could not have; no restrictions. The aerodynamics for the product
line were selected using a range of optimized combinations that would give users
turbocharger solutions anywhere between 250 and 1000 horsepower capability per turbo. Next,
a list of every notable design characteristic for an engine boosting device was
tabled. Specific interest was given to new ideas that had never been formed in metal
or had never been combined into an aftermarket turbo.
The result is the new EFR (Engineered for Racing) line of turbochargers from BorgWarner.
These turbochargers contain a bevy of key attributes such as Gamma Ti turbine wheels, dual
ceramic ball bearing cartridges and investment cast stainless steel turbine housings.
Collectively, those features help give the EFR line its innovative appeal and will
provide a breakthrough experience in durability, device responsiveness and installer/user
