VINTON, Iowa (July 23, 2026) — One of the most anticipated traditions of America’s Racin’ Vacation returns this September as Midstate Machine will once again provide four brand-new championship engines for the winners of Saturday night’s Karl Kustoms IMCA Modified, Sunoco IMCA Stock Car, Karl Kustoms IMCA Northern SportMod, and Sunoco IMCA Hobby Stock features at the 44th Speedway Motors IMCA Super Nationals fueled by Casey’s.

Built by Midstate Machine of Des Moines, Iowa, the engines are assembled using donated components from many of the racing industry’s premier manufacturers and will be presented to each of the four champions following Championship Saturday on Sept. 12 at Boone Speedway.

The presentation of the new engines allows another unique Super Nationals tradition to continue. The race-winning engines from each of the four champions’ cars will be removed and auctioned following the conclusion of Saturday night’s racing in the NAPA Auto Parts Fan Zone. The auction is open to drivers, crew members and race fans, giving attendees the opportunity to own a genuine piece of Super Nationals history.

“We’re honored to continue being part of one of the signature traditions at Super Nationals,” said John Davis of Midstate Machine. “This program wouldn’t be possible without the incredible support of the manufacturers who donate components each year. We appreciate every one of them and are proud to help reward four deserving champions.”

This year’s championship engines are being assembled with components donated by EngineQuest, Engine Pro, Manley Performance, JE Pistons, Kevko Racing, Melling Engine Parts, Comp Cams, Edelbrock, ARP, SCE Gaskets, Summit Racing Equipment, Total Seal, Bullet Cams, NAPA Auto Parts, Eagle Specialty Products, Speedway Motors and Isky Racing Cams.

Among the donated components are EngineQuest cylinder heads and blocks, JE and Manley pistons and crankshafts, Eagle connecting rods, Speedway Motors engine components, Bullet Cams and Comp Cams camshafts and valvetrain components, Edelbrock intake manifolds and water pumps, Kevko oil pans and valve covers, Melling oil pumps and lifters, ARP fasteners, SCE Gaskets sealing packages, Total Seal piston rings, Summit Racing Equipment engine components, NAPA Auto Parts ignition and lubrication products, and numerous additional premium parts supplied by the participating manufacturers.

The 44th Speedway Motors IMCA Super Nationals fueled by Casey’s will be held Sept. 5-12 at Boone Speedway in Boone, Iowa. Throughout the week, the NAPA Auto Parts Fan Zone serves as the hub of activity, hosting redraws, driver meet-and-greets, autograph opportunities and other fan-friendly events each evening.

John Shoptaw: The Flight Medic’s Racing Comeback at 65

By Ben Deatherage MENA, Ark. (Sept. 19, 2025) — The Ouachita Mountains rise green and rugged around Mena, a town shaped by timber, trains, and resilience. It’s here that 65-year-old John Shoptaw calls home — a critical care paramedic by profession, and a racer by passion. His journey has carried him from Carthage, Missouri, to firehouses across Arkansas, and back behind the wheel of a Modified long after many thought his driving days were over. On July 30, 2017, at Diamond Park Speedway, Shoptaw’s career nearly ended. “I had a horrendous wreck,” he said. “Broke my lower back, my coccyx, my collarbone, and suffered a concussion so bad you wouldn’t think I’d ever climb back in a car.” With help from a friend, he patched together a car for the Speedway Motors IMCA Super Nationals fueled by Casey’s that fall. But it never came around, and by week’s end, he sold it off. For years, he stayed away entirely. “I didn’t watch, didn’t go, didn’t want anything to do with racing,” he admitted. Golf became his [Read More]

Pulse Racing Innovations, Dirt Defender signed as Northern SportMod Race of Champions sponsors

WAXAHACHIE, Texas (May 9, 2024) – Pulse Racing Innovations is the new title sponsor for the Northern SportMod Race of Champions, providing a portion of the point fund and products to be awarded to drivers qualifying for the 16th annual event during the upcoming IMCA Speedway Motors Super Nationals fueled by Casey’s. According to owner Billy Vest, each of the 12 qualifiers for the Northern SportMod RoC will receive a Pulse Racing Innovations EZ Tear combo pack. The patented EZ Tear universal system prevents racers from discarding more than one tear-off at a time. It avoids the accidental removal of the entire tear-off stack. This is a crucial product for every racer. “I’ve been around racing since I was five years old and there is nothing else like Super Nationals,” said Vest. “There are races around the country that pay more, but with the environment, all the cars, and all the spectators, there isn’t another event like Super Nationals.” Vest is also co-owner of Dirt Defender Racing Products along with Dennis Bissonnette. The company made [Read More]

By Jane Burd BOONE, Iowa (May 16, 2026) — Joel Huggins raced from ninth starting position to score his first Stealth Racing IMCA Mod Lite victory of the season Saturday night at Boone Speedway before rain postponed the remainder of the evening’s racing program. Landon Elliott paced much of the 15-lap Mod Lite feature after taking the early lead while Charlie Brown moved into the top spot on lap nine. Huggins, from Des Moines, steadily worked his way through the field and grabbed the lead from Brown on lap 12 before driving away for the victory. Brown finished second ahead of Elliott, Jaxon Carr, and Bryan Zehm, who advanced from 12th to fifth. Garrett Barber turned in an impressive charge from the 21st starting position to finish sixth.
