TurboSource Variable A/R EFR Turbine Housing

We are currently machining our latest gen samples, and updating the actuator assembly. All test vehicles have been lined up for current samples. The TurboSource Variable A/R Turbine Housing is designed to increase the responsiveness of the EFR turbocharger lineup even further. This external waste-gate configuration housing is designed to lower the boost threshold by 600-800rpms. Most enthusiasts are torn between the ultra responsiveness of the 7670 turbocharger, and the higher peak RWHP numbers of the larger b2 frame turbochargers( 8374 through 9274). The goal here is to combine the best of the both worlds through increasing shaft speeds in the lower RPM regions( below 4K rpms for most smaller displacement engines), while being able to deliver the high RPM power of the 62-68mm B2 frame EFRS( 8374, 8474, 9174, and 9274).  The beauty of the EFR turbochargers is already dramatically increasing how wide the powerband is by the use of the Gamma-TI turbine wheel, which is half the weight of
