Commercial/industrial turbo products have extreme requirements for durability, reliability, and aerodynamic performance. Turbo sizing for the performance user more resembles what’s in the commercial realm as compared to what comes from our (and others’) OE passenger car developments. Since modern passenger car applications use turbos smaller than 55mm turbine wheel diameter, it’s the larger components used on commercial applications that are more applicable to high-power aftermarket performance use. Commercial engines often utilize high boost pressures. Gage pressures of 45+ psi [3+ bar] are quite common even while retaining extreme durability.  \nAlso required is resistance to abusive thrust loads, vibration, and robustness for a wide range of lubrication and cooling conditions. Our OE product validation standards are very tough, and many of these same practices were employed during the development of the EFR products.  \nThat was the commonality, now here are the differences. Unlike commercial applications, high performance users want lightweight, compact, versatile designs. They also deliver the turbocharger very high exhaust gas temperatures and have high expectations for fast response. They also place value in cosmetic appearance and want integrated features that aid the installation process and remove the need for other accessories.  \nSo, what happens when you combine all these requirements?  \nSomething new is required, something that really changes the game.  \n3  \nBefore a team was assembled, I selected the aerodynamics for the product line--a range using only optimized combinations that would give our users turbo solutions anywhere between 200 and 1000 horsepower capability per turbo. I also made a list of every great design feature I could think of--everything I had ever seen or heard of, new ideas that had never been taken from paper to hardware, and permutations of these that had never been integrated. Ninety percent of this content “stuck” and it was only the truly exotic that was excluded; features that would either take too long to develop across the size range or would be so expensive that nobody could afford them. Then, the program proposal was pitched to three of our top management staff. They got excited about the vision of giving this segment something remarkable and approved proceeding with the project. So, to them we all owe thanks.  \nAfter that, a talented and enthusiastic team was assembled and the rest of this text shares the det","cbCailn47xLfLiP8","https://ap.wps.com/l/cbCailn47xLfLiP8","pdf",8458795,126,"English","# Foreword\n# Product Introduction\n## Aerodynamic Selections\n## Compressor Wheels\n## Turbine Wheels\n## Turbine Housings\n## Open vs. Divided Turbine Housings\n## Wastegate System\n## Wastegate Canister Selection\n## Boost Control Troubleshooting\n## Bearing Systems\n## Oil Restrictor and Inlet Fitting\n## Oil and Water Connections\n## Gamma-Ti Turbine Wheels\n## Compressor Stages\n## Turbo Orientation Features\n## Oil Connections and Lubrication\n# EFR Feature Summary\n# Turbo Installation Notes\n# Appendix: Misc.
