SOD invades Plymouth Speedway in 2019


ERIE, MI (November 28, 2018) – The Playground of Power, Plymouth Speedway, will host Engine Pro Sprints On Dirt presented by ARP for two races in 2019.  SOD will take on the 3/8 mile speedway on Saturday, July 27th and a second date to be announced later.

Under owner Ed Kennedy, dirt track racing has returned to Northern Indiana in a big way with a state-of-the-art racing entertainment facility.  Opening as a paved track in 1952, the speedway started its transition to dirt with a ¼ mile dirt oval created inside the 3/8 mile paved track in 2012.  The current 3/8 mile dirt track replaced the paved oval in 2013.  In 2016, new seating was constructed to enhance the fan experience.

SOD raced at Plymouth from 2012 through 2015, giving SOD competitors some familiarity with the track.  In addition, several Plymouth (crate) Pro Sprint drivers also raced with SOD, so they will be right at home.

More information about the 2019 Engine Pro Sprints On Dirt presented by ARP schedule will be released in upcoming announcements.

Sprints On Dirt for four at Butler Motor Speedway in 2019


ERIE, MI (November 23, 2018) – Once again, Michigan’s two leaders in sprint car racing, Butler Motor Speedway and Engine Pro Sprints On Dirt presented by ARP have joined for four races in 2019.  The first race will be May 11th followed by June 15th, July 6th, and August 3rd.

The four 2018 SOD races at Butler had four different winners.  Chase Ridenour (Perry, MI) won on May 19th over Boston Mead (Onsted, MI) and Chad Blonde (Litchfield, MI).  Josh Turner (Osseo, MI) took the June 16th over Chad Blonde and Shawn Valenti (Fostoria, OH).  The August 3rd win belonged to Chad Blonde followed by Ryan Ruhl (Coldwater, MI) and Boston Mead.  Shawn Valenti took the August 4th victory over Chad Blonde and Quentin Blonde (Litchfield, MI).

The strong partnership between Butler Motor Speedway and Sprints On Dirt continues in 2019 to ensure a strong future for sprint car racing in Michigan.  Last spring Butler and SOD implemented a common rule for the Butler sprint car class and Sprints On Dirt competitors requiring full containment seats in 2018.

Butler Motor Speedway has undergone several major changes over the years.  One was moving the pit area out of the infield; another was replacing the racy oiled dirt track with the current watered clay surface in 1996.  Last spring the track banking was reduced by about one-third.  2019 will see other changes that will be announced later.

More information about the 2019 Engine Pro Sprints On Dirt presented by ARP schedule will be released in upcoming announcements.

40th SOD season opens at Crystal Motor Speedway


ERIE, MI (November 21, 2018) – For the 40th consecutive year, the Crystal Motor Speedway / Engine Pro Sprints On Dirt presented by ARP partnership continues in 2019. The 2019 SOD races at Crystal are scheduled for April 27th followed by July 13th and August 31st dates with a May 4th rain date for the opening race. Popular traditions will continue for Crystal/SOD races with the SOD season opening at Crystal and the Mike Olrich Memorial Race on Labor Day weekend.

Crystal Motor Speedway owner/promoter Ron Flinn was honored last February as the Region 3 Auto Racing Promoter of the Year by Racing Promotion Monthly and Charlotte Motor Speedway. He was inducted into the Michigan Motor Sports Hall of Fame in 2007, and has also been named “Promoter of the Year” from both the Michigan Speedway Promoters Association and the “Michigan Auto Racing Fan Club.”

At last year’s SOD season opener at Crystal, Zane DeVault (Plymouth, IN) drove to his first SOD victory by just 0.03 seconds over hard-charging 2018 SOD champion Chad Blonde (Litchfield, MI) and Matt Foos (Fremont, OH). Not only was the racing exciting, but SOD’s “Beyond Limits” format once again proved itself with DeVault winning with a 360 engine over Blonde’s 410 and the 305 of Foos. Shawn Valenti (Fostoria, OH) took the win on July 14th over 2018 Butler Speedway champion Boston Mead (Onsted, MI) and 2018 MTS champion Steve Irwin (Fenton, MI). The much-anticipated Mike Olrich Memorial on September 1st was rained out.

More information about the 2019 Engine Pro Sprints On Dirt presented by ARP schedule will be released in upcoming announcements.

Dave Muzzillo announced as new Sprints On Dirt owner


FB link on red 1200x627

ERIE, MI (November 2, 2018) – Over the years since its creation in November, 1979, Engine Pro Sprints On Dirt presented by ARP has been the leader in sprint car racing in Michigan.  A new chapter in SOD history is opening with the acquisition of SOD by Dave Muzzillo of Fort Wayne, Indiana.

Muzzillo is well known in oval track racing.  He has been promoting racing and other public events for many years.  He is recognized as a personable innovative promoter who is willing to think out of the box.

Sprints On Dirt has been a pioneer in sprint car racing under John Naida, making strategic changes over its thirty-nine years.  In 2016, it transitioned from a 360 series and rolled out a radical new format known as “beyond limits” that has no engine or weight limits.  Naida took over active management of the series three years ago and introduced the new format and new spec rear tires.

Utilizing Hoosier Racing Tire right and left spec rear tires specifically built to meet SOD’s needs, the main objective of the “beyond limits,” achieving equality among different engine sizes and configurations, has been a success.

Muzzillo does not plan on making any changes to the “beyond limits” SOD format, adding, “If it’s not broken, don’t fix it.”

Naida continues scheduling and working with SOD marketing partners and will help with race day operations when the new season begins.  “I will do everything I can to help Dave.  His passion for racing will be great for SOD’s future” said Naida of how the transition will take place.

Muzzillo has had a life-long involvement with racing and sprint cars in particular. His father was pit steward with Tri-Sac and his step father, Dale Miller, drove sprint cars.  Muzzillo is now the owner of Baer Field Speedway in Fort Wayne, Indiana, and operates the International Championship Auto Racing (ICAR) Modified series. Muzzillo has also acquired the crate sprint series that raced at Plymouth (IN) Speedway and it will now be a feeder class for Sprints On Dirt.

Since its first season in 1980, Sprints On Dirt has built a strong brand name that is recognized and respected throughout sprint car racing.  It has built a strong relationship with its many marketing partners due, in part, to its strong online presence.  It often states that “SOD puts the PRO in PROmotion.”  Muzzillo is committed to take Sprints On Dirt to new heights.
