The 10 Biggest, Baddest, and Craziest Engines We Could Find At The 2019 PRI Show

The Performance Racing Industry Show held in Indianapolis, Indiana, at the conclusion of each year follows the big car show that is the SEMA Show in Las Vegas. Where the SEMA Show covers the entire automotive aftermarket, from tools to trucks to speed parts, the PRI Show is hard core racing parts with a little bit of machinery and trailers thrown in. With that, it should come as no surprise that it’s the epicenter of new horsepower and speed parts, and many companies show these off with an engine or vehicle—or sometimes both—in their booths. Here is a look at some of the engines in attendance, all of which are huge horsepower makers in their own right.

Oakley Competition Engines, which took home the Engine Builder magazine Race Engine Shop of the Year Award at the PRI Show, had one of its engines on display in the Vortech Superchargers booth. Oakley builds this combination in varying displacements from 540 up to 588 cubic inches using Brodix aluminum blocks, cylinder heads, and intake manifold. As you can see, it runs a blow-through, carbureted induction system from APD, a Vortech V-30 blower, and produces over 2,300 horsepower.
Larry Larson’s latest creation, a 2016 Cadillac ATS-V built for No-Prep racing, was in the TurboSmart booth showing off some of the company’s products. The basis of the engine combination is a Pro Line Racing 481-X V-8, and where most teams run a pair of turbochargers on this same engine, Larson chose to go with a huge single 140mm unit from Hart’s Diesel and Machine. Running via a FuelTech FT600, the powerplant is estimated to make around 4,500 horsepower!
ARP products are used worldwide in myriad applications, though the company is probably most noted for its engine fasteners. In the ARP booth was this wild V-16 engine for the marine industry from XVI Power, which uses a proprietary block and crank, along with conventional LS-based cylinder heads and intake manifolds, or in this case, Whipple superchargers. In naturally aspirated form, XVI offers this engine in 900, 1,200, and 1,400 hp options, but adding a pair of superchargers or a quartet of turbochargers takes the low-boost engine past the 2,000hp mark.
Steve Morris Engines built this beautiful LS-based, twin-turbo engine for Clark Rosenstengel’s 2010 Camaro, which competes in Hot Rod Magazine’s Drag Week, as well as other standing half and mile events. Bullseye 83mm NLX turbochargers force air through an air-to-air intercooler and into the Noonan cylinder heads and billet, water-jacketed block. The engine, which we found in the Isky Racing Cams booth, is run using Holley EFI and this street-car engine makes 1,600 on pump gas and over 2,500 horsepower and 1,900 lb-ft of torque on race gas, with power output limited by the intake manifold and exhaust sizing that is used to keep it a “street” car.
Pro Line Racing is known the world over for its championship winning powerplants and racing programs, and the company keeps evolving its product lineup to stay ahead of the competition. It’s new raised-cam Hemi engine ushered in several changes designed to make more power and increase durability. Its being used in twin-turbo applications with many NHRA Pro Modified racers as well as NMCA Xtreme Pro Mod competitors, but this particular 564 cubic-inch beast—shod with a fancy billet intake manifold from Magnatron—builds on the company’s relationship with ProCharger and utilizes a ProCharger F3X-140 superchargers to make over 5,200 horsepower.
We couldn’t help but include this old-school, blown, big-block Chevy for several reasons. First, it was the pinnacle of Pro Street performance back in the 1990s, and secondly, this particular engine rests inside a 1969 Camaro that belongs to Pro Street legend, Rod Saboury. Saboury bought the car brand new and built it into a Pro Street machine in the 1990s. He later sold it to a friend, and amazingly was able to buy it back in the same condition just a few years ago. Saboury has updated the Camaro by having a five-speed manual transmission installed.
Ford-based engines were a bit of a rarity at the 2019 PRI show, with many falling into the street category, but we did find one that stood out and could hold its own against the Chevy-based mob. Modular Motorsports Racing dropped off one of the company’s Mustang Pro Mods to the Garrett In Motion booth to show off its Garrett turbochargers. The Mustang is powered by the quickest and fastest, Coyote based engine and uses MMR’s proprietary billet block and heads to push the pony to high 5-second quarter-mile times.
This 572ci powerplant is brand new from the Scoggin-Dickey Race Shop. Known for selling Chevrolet Performance crate engines, the company’s Race Shop division has expanded that lineup and now offers big-power-capable engines like this one, which starts with an Energy Manufacturing block, cylinder heads and intake manifold. SDRS then fills it with forged internals and bolted on an F3R-136 supercharger to produce 2,500 hp and 1,700 lb-ft of torque.
We were strolling through the Afco Racing booth when the shine from Jarrod Wood’s Radial-vs-the-World Corvette caught our eyes. Underneath the front nose sits a billet Noonan Engineering Hemi engine with twin turbochargers. Easily capable of 4,000-plus horsepower, the powerplant and its peripherals have been polished beyond compare. Finish fabrication work was performed by Rock Solid Motorsports.
Last, but not least, is this wild LS-based V12 engine that we came across in the Haltech booth. While the engine itself has been on the scene for a few years now, and in Haltech’s booth in the past, this is the first time we’ve seen it with four GTX3582 turbochargers bolted to it. Haltech wired up its new Nexus EFI system and the company estimates it should make an easy 1,000 on pump gas at low boost.
