Coyote Modified - NMRA’s Newest Heads-Up Class
Starting in 2014, Coyote Modified will be NMRA’s newest addition to the heads-up racing category! It was only a matter of time before the Coyote 5.0L powerplant received a class all its own.
“As the biggest Ford drag racing series we have a commitment to the racers and sponsors to grow sportsman heads-up drag racing and adding Coyote Modified is a big step forward,” NMRA Tech Director Dave Werremeyer said.
The Coyote Modified (CM) should bring in a whole new level of boosted and nitrous-fed cars to the NMRA scene. This new Coyote Modified class will receive special attention from aftermarket manufacturers, late-model tuner shops, and the sportsman drag racer.
The goal for the new Coyote Modified class is to allow the power adders to dictate the mechanical limits instead of a long list of limitations. This will allow a wide range of competitors to enter the class from street cars to full-out racecars. “Last year we launched the first-ever sealed crate engine program in drag racing history with the popular Strange Engineering Coyote Stock,” explained Werremeyer. He continued, “that class is awesome with over 25 Ford Racing engines sold and we are looking at full fields in 2014. As we looked at the heads-up categories in NMRA, we offer two naturally aspirated classes with Nitto Tire Factory Stock and Strange Engineering Coyote Stock. Then we jump into the exciting world of Edelbrock Renegade with mid-to-low eight-second cars and the awesome AFCO Street Outlaw class that runs mid-to-low sevens. We felt if we are going to add a category then it has to fit right in the middle of our current heads-up offerings.”
Werremeyer and his team collected significant amounts of data from on-track performances such as test and tune nights, 5.0 Shootouts, and even Cobra Jet performances. Discussions with manufacturers, specialty tuning shops, sportsman drag racers, and engine builders all did their part to help shape Coyote Modified.
Coyote Modified will get extra special attention with 5.0 Mustang & Super Fords Magazine coming on board as the presenting sponsor of the class. “We have been covering the Coyote 5.0-liter engine since it was born, so to see it pushed to the outer limits of its performance in the NMRA’s new Coyote Modified class will be truly exciting,” said Steve Turner, editor-in-chief of 5.0 Mustang & Super Fords magazine. “We have already seen some of these cars perform at incredibly high levels, but to see them compete against one another is a tantalizing proposition. It's an idea our magazine team couldn’t resist being associated with.”
“In the late ’80s the excitement of watching wildly modified 5.0 Mustangs race is what propagated the Mustang aftermarket to the robust level it operates at today,” Turner added. “With any luck, the NMRA’s battle of modern 5.0 Mustangs in Coyote Modified will accelerate the rapid development of Mustang speed parts far into the future.”
