Power Range

The EFR product line contains a compressor range from 62mm OD (~50mm inducer) to 91mm OD (~68mm inducer).  From this, the 70mm through 91mm compressors are designed for high-boost (30+ psi) capability.  Born from our work in highly-boosted, highly-efficient commercial engines, these compressors define “top-shelf” in terms of efficiency, range/width, and of course pressure ratio (boost) capability.  On the turbine end of the machine, the range is from 55mm OD to 80mm OD.  These turbine shapes are the newest “superback” and “fullback” designs from our work in high-boost, high-efficiency applications.  These are low-stress designs capable of considerable speeds and high efficiency.  The compressor and turbine “pairing” is what it should be to maintain the best turbine inflow incidence, and the turbine housing A/R’s are all selected to also optimize turbine stage efficiency.
