Day 3 Coverage-2021 Performance Racing Industry (PRI) Show

Today marks the final day of the 2021 PRI Show, and it's been great to get back to an in-person show. The show floor is thriving with activity, and there is a wide range of noteworthy products and race cars on hand. Of note for racers running the COPO Camaro, Mustang Cobra Jet, Dragpak Challenger, and other supercharged modern muscle cars, Dayco Supercharger is rolling out a supercharger belt early next year. Starting with 17 part numbers that will cover a vast array of vehicles, including ZR1 Corvettes, Shelby Mustangs, and SRT Hellcat applications, Dayco put more than 2,500 hours of development and testing into these belts to deliver increased grip and longevity. Based on a high-stiffness PET cord with an EPDM proprietary construction, the belts are available in eight- and 10-rib configurations. Ford engineers likely never imagined that racers might leave the line with 1,000 lb-ft of torque from a nitrous hit on a 7.3-liter Godzilla engine. However, when that happens the factory timing chain and its thin-wall retaining belt are a liability. That's why Paul's High-Performance developed this direct-replacement arrangement with stout gears, chains, and fasteners. It is a simple, affordable way to ensure the engine's valves and pistons don't meet. To help get the word out about the launch of its automotive classifieds system, RYNO Classifieds teamed up with Dream Giveaway Garage to show off a 2021 Dodge Charger Hellcat Redeye and host NHRA top-fuel driver Leah Pruett for an autograph signing that attracted lots of fans. For big-power applications, Turbosmart developed its all-new ProPort blow-off valve. It flows a whopping 420 cfm, which is enough to support combinations up to 3,500 horsepower. Sensor cap and spring options are available for any turbocharged and supercharged applications. It features a quick-release V-band mount and can be optioned with an onboard position sensor. This Ford Godzilla 7.3-liter engine is truly a monster. Prowling in the ProCharger display, the Willis Performance Enterprises-prepped engine is fitted with a ProCharger F-1A94 supercharger driven by the company's crank-drive system. Fitted with Visner induction and ported heads, the de-stroked engine percolates with 13:1 compression and should deliver impressive four-digit performance. With modern Hemi engine swaps taking off, Holley is making that process even easier thanks to its new Gen III Mid-Mount Accessory Drive. Bracket-less thanks to an integrated timing cover, this front-end accessory drive is complete right down to the alternator, power steering pump, and A/C compressor. It is available in silver or black finishes. There is a great deal of 7.3 Godzilla hardware at the show, but if you want a complete crate engine straight from the factory, Ford Performance offers this crate engine. The same powerplant available in the Super Duty pickup, this engine delivers 430 horsepower and 475 lb-ft of torque. For those pushing big power, Sonnax developed this 258mm Performance Torque Converter kit for Powerglide. Making it easy for transmission builders to assemble the kit includes a machine cover with bushing; oil-flow grooves for improved fluid flow and cooling; and a turbine hub with larger flanges that fortify its rigidity. Builders can opt for a range of stator and impeller combinations to dial in the right stall for a given combo. For owners of four-digit muscle machines who want to bang gears with TREMEC Magnum six-speed manual transmission, G-Force Racing Transmissions now offers its robust GF Street 6 package. This drop-in upgrade delivers the reliability of a racing transmission while retaining complete streetablility thanks to the company's re-engineered gear design and tooth profiles. It can be utilized with factory or G-Force overdrive gears. NMRA regular Leticia Hughes's 2018 Mustang GT held court on the PRI Show floor repping for Suncoast Performance. Regular readers know that her naturally aspirated Coyote benefits from the company's transmission upgrades, as well as a full Steeda suspension, Mickey Thompson tires, and more. This combination has proven quite successful, yielding 13 trips to the winner's circle thus far. A transmission that will hold up to the stresses of big power and repeated runs is key in racing. Coan Engineering's Turbo III XST transmission is built for battle with a billet aluminum stator shaft and your choice of billet aluminum, steel, or titanium clutch drums. Its SFI certified case is fitted with the company's Ultimate XST main shaft as well as a 36-element Super Sprag and a billet alloy output shaft. This example also highlights Coan's new billet aluminum bellhousings that are available for a variety of custom applications.
