NMRA's Coyote Stock

Ccrp 1206 Nmra Coyote Stock Racing Ford Mustang 01

There is a new class in NMRA this season, and it’s generating quite a stir on message boards and YouTube, yet as we write this, the season’s opening race is still one month away. Strange Engineering Coyote Stock presented by 5.0 Mustang Magazine and Super Fords is the official title of the class, and there are several reasons to be excited about it. First, it was created to simplify an existing NMRA class and make it more affordable than the class it evolved from. Second, the rules dictate the use of a sealed, 5.0 Coyote crate engine, which is available from a number of distributors for about $6,000—a great price for the level of performance it delivers. In the words of one builder we spoke to, “You couldn’t piece together a better engine for less money.” Third, the engine is legal in any ’54-or-newer Ford and can be backed up by any Tremec manual transmission or a C4 automatic, which satiates our appetite for drivetrain swaps. Fourth, it’s heads-up racing. Early testing we’ve seen shows the cars nailing down high-10-second e.t.’s in shakedown passes. This class should be fun, fast, and competitive.

According to our research, Coyote Stock was the brainchild of NMRA Pure Street racers Steve Gifford and Ken Bjonnes. In a conversation with Ken, he described his frustration with what had become of Pure Street, an N/A Modular-powered class. A myriad of weight breaks and a rules guide as thick as a phone book made a competitive car expensive and difficult to build. Bjonnes described one racer showing up a couple of years ago with a huge-budget ringer car that instantly put everyone else on the trailer. That type of racing isn’t fun. He and Gifford began kicking around ideas of how things could be better.

    Lots of the NMRA action happens on the East Coast, but we received a lucky tip-off that a car was also being built here on the Best Coast. We drove up to Lancaster, California, to see the crew at Calvert Racing assemble a '95 Mustang specifically for a customer competing in Coyote Stock.

    Calvert's Mike Hernandez tells us he took delivery of the car, engine, and transmission three days before we arrived to prevent him from becoming distracted by our cameras and probing questions. These guys work fast. This car was delivered to them as a rolling chassis--no engine or transmission and with just a rollcage, a tubular K-member, and front coilovers.

    The major difference between the sealed version required by NMRA's rules and FRPP's standard Coyote crate engine are these caps covering some of the timing cover and intake manifold bolts. It's impossible to remove the caps without destroying them, and destroyed caps will get you kicked off the grid.

At about the same time, Ford Racing Performance Parts released the crate version of the ’11 Mustang’s stellar 5.0L engine, and the plans started to come together. Bjonnes said he lobbied both FRPP and the NMRA with what he calls a simple set of rules. Both parties liked the idea, and the rest, as they say, is history.

Well, more like history in the making. As of early February 2012, we’ve heard of just a handful of cars being built to compete in this new class, so there is a chance this whole Coyote thing could chew off its own leg. NMRA’s first race will be held in Bradenton, Florida, before this goes to press, so we’ll know more then. We are optimistic, however, and applaud the notion of a stripped-down set of rules governing a heads-up class of newer engines in older cars. We’d like to see Dodge and Chevrolet come up with similar spec-engine programs; then the Big Three could all throw down in some sort of late-model engine-swap class, possibly sponsored by us here at CC. Innovation, modern technology, and heads-up racing on a budget sound like a great combination.

    Hernandez says the oil pan on the sealed crate engine is slightly different from other versions of the Coyote engine he's encountered. There is an extra dip that interferes with this car's UPR K-member.

    Hernandez's temporary fix was to raise the engine with these spacers he cut from aluminum plate. He says he may modify the UPR K-member or make a new one depending on available time and the customer's budget.

    Raising the location of an already tall and wide engine eats up valuable real estate in the engine compartment. Obviously, there is no way a vacuum-assist power-brake booster would fit here. Other Coyote swaps we've seen have used hydroboost units that Ford put on 4V Cobra Mustangs, but we're not certain that even a hydroboost would fit. This is not a concern in a race car, but a guy considering a swap into a street car should be aware of oil pan and crossmember fitment.

    The Coyote's factory fuel rails are designed for a returnless-style fuel system, but the fuel pump in this Mustang uses a return-style system and is constantly running. To save the customer some money, Hernandez modified the fuel rails, welding a fitting for a return line.

    FRPP offers an alternator kit separately from the crate engine. The suggested price is $229.95. Be sure to factor that into the cost of the build.

    The ECM and wiring harness required to run the engine are also sold separately for $1,600. Hernandez says this is all quality stuff, with OE-style loom and wire wrap. He also likes the relay box that includes LED indicators to verify that all the components are getting power. Per NMRA rules, no fiddling with the ECM is allowed, and at any time, an NMRA tech official can reflash your ECM in the staging lanes or even swap it with the ECM from a competitor's car, all in the interest of keeping the playing field level.

    The FRPP controller kit also includes the electronic throttle pedal. Hernandez says it didn't fit the floor of this SN-65 Mustang very well and required an adapter plate to bolt it in.

    Per the rules, aftermarket K-members are allowed. In fact, they would be required to fit a Coyote in a non-modular-powered Ford. Coilover shocks in the stock mounting locations are permitted as well.

    Aftermarket trailing arms are also permitted, but they must attach in the stock locations. This car is wearing UPR uppers with stock lowers. An aftermarket sway bar was installed by the previous owner, but Hernandez says he'll probably remove it. Note the sumped stock gas tank. The previous owner modified the tank for an external pump, but Hernandez capped the fittings and installed a Walbro in-tank unit. Though it was the less expensive option, it will deliver enough fuel for the engine.

    Both automatic and manual transmissions are permitted, but we suspect a manual would be quicker. Just about any Tremec manual transmission is allowed, but clutchless shifting is not permitted. This is a TKO-500 attached to a Quick Time bellhousing and McLeod clutch.

    The guys at Calvert are shooting to have this entire car built for a total cost of $15,000 (including the cost of the car), but they suspect the total bill may be closer to $20,000. Still, that is a very reasonable price tag given the performance potential the Coyote Stock class offers. We expect quarter-mile times in the mid-to-high 10-second range, based on early testing results. Go to NMRADigital.com for more information. Better yet, attend one of NMRA's events this year for all the sights and sounds of Coyote Stock racing.
