The turbochargers have been completely redesigned with some pretty cool features that, if truly functional, may justify the ~$1500 price tag. They all come with integrated Boost Control Solenoids and speed sensor ports; many of them come with well-designed integral wastegates, and the actuators bolt to the center housing instead of the compressor housing so you can spin the housing to just about any rotation you need; integrated by-pass valve (ie recirculating blow-off valve). They say these features are actually useful and efficient even in high horsepower applications and have OEM/high quality durability. I'm intrigued.
The BorgWarner EFR turbo is set to become the new world standard for performance turbocharging due to the high-technology feature package, unbeatable performance, and installation convenience. The EFR turbocharger was designed and manufactured with only one purpose in mind: to dominate the street, track, and strip. (7) different sized turbos, optimally matched for the 250-1000hp per turbo segment - and in (4) different turbine housings are the result. The combination of this top-shelf geometry and the Gamma-Ti turbine wheel significantly raises the bar for performance aftermarket turbochargers. Combined with our ball bearing technology, it is the most responsive range or turbos that are available anywhere, at any price. The EFR series covers all applications except the hardcore drag racers. For those hardcore customers, we still offer the highly popular S400SX and S500SX product lines, and will continue to update those turbos during the next year.
I did a search for EFR and came up empty.
