Xona XRC5764S — N55
The Xona XRC5764S is a ball-bearing turbocharger built on the XR64S UHF 64mm turbine wheel. Compressor: 57mm inducer / 79mm exducer; 74 lb/min rated flow; published range 450–740HP. Xona rates the XR64S UHF design as delivering the fastest response observed at this power level, attributed to the splitter-blade aero's inertia reduction. Configured here for the BMW N55.
Turbine housing — Material, Flange, and A/R — is selected using the guided cascade above. Compressor cover (X2C or X3C) and SwainTech coating are also selected above.
SwainTech White Lightning thermal barrier coating is available on the turbine housing (hot side), compressor housing (cold side), or both — add it via the Coating option. Ordered BYO Core?
