Whether naturally aspirated or propelled by nitrous, turbos, or superchargers, race engine technology was front and center at the industry’s annual salute to speed in downtown Indianapolis.

Each December, top suppliers show off their muscle in the form of high-performance engines on display at the annual PRI Trade Show.

Various motorsports disciplines are represented, including truck and tractor pulling, sprint and midget racing, UTV performance, drag racing, marine performance, the import market, and much more.

While it’s nearly impossible to single out a favorite from the Show floor, we did manage to hone in on 10 impressive powerplants showcasing a bevy of hardcore race parts across diverse applications—which can only be found at PRI.
