Evo X Top Mount Vband Turbo Kit
Designed specifically for competitive racing use, the EFR 7163 is Borg Warner's newest addition to the EFR family. Latest generation compressors combined with state of the art 'Mixed-Flow Gamma-Ti Turbine Wheel' design allows for remarkable spool and huge powerbands. This unique turbocharger is literally an off-the-shelf Indycar turbocharger, used by all 2014/2015 IRL teams.
Starting with the head flange, we use CNC billet 1/2" flanges for a strong, consistent and smooth transition into the runners from the head. From there, the exhaust travels through equal length 316L stainless steel weld els that have been back purged with full penetration welding into a cast 304 merge collector. While using our unique welding techniques, we are able to get full penetration, single pass welds while minimizing heat input to prevent warping of any of the flanges. Each port runner, vband outlet, and wastegate outlet are all ported for smooth transitions and proper boost control to prevent boost creep.
