Livernois’ Really Rapid Raptors

The bolt-on performance enhancements described in our main story simply scratch the surface of Livernois Motorsports’ Raptor revitalizations. For a customer in the Middle East, the shop just finished and shipped a twin-turbocharged Raptor that made 635 horsepower and 767 lb-ft of torque at the tires. That’s more like 760 horsepower and 920 lb-ft at the crankshaft. It took more than a couple of turbos sandwiched into the exhaust stream to achieve that power. The combination includes:


  • Livernois’ 400ci “stroker” bottom end (the stock 6.2L displaces 379ci, and this project truck started life with the even-smaller 5.4L)
  • Livernois’ own CNC-ported cylinder heads (used with the stock camshafts)
  • A custom valve spring kit and rocker brace system developed by Livernois
  • A custom turbo system featuring two quick-spooling, dual-ball-bearing Garrett GT35R turbochargers and a large intercooler
  • Magnaflow exhaust system
