Details
This custom-built 67mm compressor wheel is specifically designed to maximize peak power while maintaining a wide, usable powerband. To fit the monster compressor wheel Calibrated Power Solutions developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section, which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. Even the wastegate has been updated to make sure you have the most amount of power and the quickest spool-up. The LB7 Stealth 67 features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. The monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure. This not only helps make more power but also manages EGT's under heavy load. To complement this turbo, we highly recommend the LB7 Stage 3 High Flow Intake Bundle Kit (WCF100712) to maximize performance, EGT control, and spool up. Looking for more yet? Add the stealth 67 in addition to one of our S400/Stock Compound kits and you've got the recipe for 1000 RWHP. This Turbo is designed for you if you...
