After Swapping Slicks for Radials, Harringtons are Ready to Race NMCA at Summit Motorsports Park

Whether they’re behind the wheel of the ’92 Mustang they share or mountain-biking on a trail near their Michigan homes, brothers Chris Harrington and Jeff Harrington, Jr. are fiercely competitive.

Chris was runner-up at a recent Outlaw 10.5 Association race in Canada and Jeff is sixth in NMCA Mickey Thompson Radial Wars points as he readies to roll into the highly-anticipated 8th Annual NMCA Muscle Car Nationals featuring the Chevrolet Performance LSX Challenge and the Ford Racing Cobra Jet Showdown at Summit Motorsports Park, Aug. 21-24, 2014. The heads-up, eighth-mile class allows naturally-aspirated, blower, turbo and nitrous combinations and Mickey Thompson 315 drag radials, Mickey Thompson 29.5X10.5W slicks, Mickey Thompson 275 drag radials and Mickey Thompson true 10.5 slicks.

Under the hood of their car — which features a Team Z Motorsports-fabricated 6.0-certified chrome moly cage — is a small-block Ford built by Jon Bennett with a billet Callies crank, Diamond pistons, BME aluminum rods, Edelbrock SC1 heads by Jon Bennett and a custom intake which they designed and built themselves. Motivating the already very motivated combination are twin 88mm Garrett GTX 5018R turbos by Turbo Direct and tuners Patrick Barnhill and Jason Lee of PTP Racing help dial it all in with Big Stuff 3.

While the Harringtons had in previous years been running Mickey Thompson 10.5WX33 slicks under the car — which has posted bests of 4.28 and 170 mph mph — they moved to Mickey Thompson 29.5X10.5W slicks early this season, but recently tested with 315 Mickey Thompson drag radials for the first time and will roll on them for the event at Summit Motorsports Park.

“During testing, the 330-foot times showed promise as far as performance goes,” said Jeff.

The Harringtons, who have said that they consider their biggest accomplishments to be the fact that they’ve progressed through the years and have been competitive in the tough-as-nails fields they enter, receive support from their dad, Jeff Harrington, Sr., their mom, Mary Harrington and Jeff’s wife, Karen Harrington.

“We’re looking forward to the Norwalk race because that’s one of the nicest tracks we race at,” said Jeff. “On top of that, NMCA has been doing a really good job on the track prep, so hopefully we can manage some good times with the change to radials.”

In addition to heads-up racing, the event boasts index, bracket and True Street racing in addition to a car show, midway and swap-meet. For information, please visit or
