For serious performance, you need serious components. That's why we're offering the FP400 line of large frame turbochargers. We've taken the heavy hitting, super reliable Borg Warner S400 series and severely improved it.

We start with a genuine BW S400 CHRA and tear it down to basic components. Then the thrust bearing is replaced with a 360 degree oversized pad for maximum thrust capacity. The journal bearings are also replaced with higher flowing oil ported versions to aid in keeping the bearings cool under heavy loads. All the rotating parts are zero balanced and then assembled with the newest HTZ compressor aero wheels that are made 100% in the USA,and the assembly is balanced a final time to verify the perfect nature of the CHRA in its assembled state. To ensure long life for this turbo, use a -6 oil supply line.

The XR484 model in our lineup flows 135+ lbs/min with its 84MM compressor wheel. That puts this turbo in the 1200-1400 HP range for both high PR, small engine applications or lower PR V8 applications.

To complement the increase in compressor flow, we brought in Xona Rotor derived tech in the form of the Ultra High Flow 88S turbine wheel. While having the same physical size as the tried and true BW 96/88mm turbine wheel, the 88S allows massive gains in choke flow capacity without hurting spool.
