"Confident that with the bigger housing, 2500+ should be no problem!"
We have a New World Record for highest WHP VK56! Jon Rogers has become known in the stick-shift drag racing world for pushing import drag platforms well past conventional limits, moving from SR20 and 2JZ's into one of the wildest VK56-powered builds out right now. His VK56 program has helped put the platform on the map as a legitimate big-power alternative, so we are proud to see Jon make the switch over to the new GXR Series of Garrett turbos: the G-XRace GXR57-98 98.9mm.
The car just made 2321 WHP at 51 psi and 2260 WHP at 47 psi. As Jon said, “We could tell we had hit the zone where back pressure wasn’t happy and it was falling off up top. We had a larger 1.41 turbine housing with us but ran out of time... confident that with the bigger housing, 2500+ should be no problem!”
Jon’s Nissan 5.6L VK56 platform uses a factory aluminum block, stock sleeves, and original factory crankshaft, and is methanol-fed. Inside, the engine uses custom forged pistons and heavy-duty connecting rods, paired with HeadGames pocket-ported factory cylinder heads, Kelford cams, GSC valvetrain, a stainless fuel hoop, and copper head gaskets.
Boost now comes from a Garrett G-XRace GXR57-98 98.9mm turbocharger, giving this high-revving VK56 the airflow capacity, pressure-ratio capability, and high-flow efficiency needed for the new horsepower figures. A Ross Performance dry sump oiling system supports oil control, while the Haltech Nexus R5 VCU handles engine management through a universal wiring harness. 🏁🚗💨
