Working closely with Garrett’s cooling engineers, with hours of CFD flow simulation, we were able to target the highest velocity areas in the plenum to maximize water distribution throughout the core. We also targeted to get the most uniform flow distribution as possible on the coolant side. Putting the tank on top not only delivers more coolant but more core surface area inside the plenum. The Garrett RZR intercooler is unique in several ways: Vertical flow core design with tank on top, not...

RZR XP1000 and XPT motors are notorious for excessive crank case pressure, the factory breather system recirculates crank case blow by back into the intake system from a breather box on the lower front side of the engine case.   The main problem with this design is how close the breather box is to the oil pan allowing oil to be carried out with the crankcase blow by and then put into your intake charge and burned. XPT models are known for rod bearing failures due a number of issues, one bein...

BC offers stock bore XPTurbo cylinder jugs that have been hopped up with copper o-rings and .500" dowels that mate to the cylinder head to keep both from shifting at high boost levels. We choose the XPT cylinders because of the closed deck design and the fact that they're +.050" taller deck height. This adds rigidity and support to the cylinders as well as delivering less piston side loading with an optimal compression height design piston. BC also offers a +1mm overbore (94mm) that has been...
