The new EFR-Series of product are the highest technology turbochargers ever available to the aftermarket, period.

With features and benefits such as:

  • Low Inertia Turbine Wheel
  • Gamma-Ti turbine wheel cuts turbine inertia by roughly 50% dramatically improving turbo response.  Turbine sizes range from 55 to 80mm in exducer diameter
  • Heat Resistant Turbine Housings
  • Investment cast stainless steel turbine housings improve durability and offer an offer extremely smooth internal flow channel.  Turbine housings have thin walls to reduce weight and thermal inertia.
  • High Turbine Efficiency
  • Superback” and “Fullback” back-disk shapes offer very high efficiencies. The Superback shape adds a curved profile to the back-disk and has the effect of lowering centrifugal stress and permitting higher rotational speeds.
  • Enhanced Turbo Response
  • EFR turbochargers use a dual-row ball bearing cartridge with ceramic balls and metal cage.  This bearing system provides substantial friction reduction at low turbo speeds and in the process helps improve turbo response.  Metal cage improved the durability of the ball bearing assembly
  • Flexible Compressor Cover
  • The EFR turbo “large” cover has a dual-machined outlet, both for a hose connection and a v-band connection.
  • Simplified Installation
  • Integrated compressor recirculation valve (CRV) to help avoid compressor surge and backflow during a throttle lift event.  This feature helps to simplify the installation task and lowers overall system install cost
  • Forged Milled Compressor Wheels (FMW)
  • EFR turbos contain wheels that are fully milled from forged aluminum, commonly known as “billet”.  Cut from custom forgings, their strength exceeds that which is available from typical bar-stock and also exceeds the material properties of an aluminum casting
  • Sensor mounting convenience
  • Speed sensor mounting provisions are also supplied on every compressor cover.  Speed sensors are sold separately.
  • Boost Control Solenoid Valve (BCSV)
  • A boost control solenoid valve (BCSV) is included with every EFR turbo.
  • High Flow Wastegates
  • Purpose designed large wastegate ports give the wastegated EFR turbos the capability of handling the flow requirements of high performance applications
  • Ease of Orientation
  • Turbo orientation flexibility is facilitated by the wastegate bracket to bearing housing mounting arrangement.
  • Adjustable Wastegate
  • The fabrication and installation task is simplified with wastegated EFR models that feature adjustable wastegates available in three different canister sizes.

This new family of products, complete with support components, and introducing new Super Core and Loose Turbine Housing options, will allow the high-performance tuner an unrivaled line of products.
