Pure Weight Loss—Project Pure Evil Drops Weight for World Cup Finals Prep


Our resident project car, Pure Evil, had a decent showing at the NMRA World Finals + Holley Ford Fest when it dropped into the 8.80s in warm weather action. A few weeks after the NMRA season ended, Mike Washington—the car’s owner/driver and project curator—began prepping for the postseason action.

All year long our goal was to field a competitive NMRA Limited Street entry and take aim at crushing our own Naturally Aspirated Coyote record (8.77 at 154 mph) during the World Cup Finals, held in late October at Maryland International Raceway. The weather conditions are always favorable and the rule package allows Washington to go off script and get wild. He has spent the last few weeks shedding nearly 150 pounds from the 1993 Mustang LX and making a few drivetrain upgrades at EB Custom Works.

First on the list was to ditch the factory doors and he picked up a set of HO Fibertrend fiberglass replicas. The fiberglass doors are factory appearing and allow for the windows to still go up and down, a rule requirement for World Cup Finals. The composite doors saved 46 pounds each side over the factory ones. The next move was to ditch the quarter-glass windows in favor of a pair of Shoneck Composites carbon fiber panels (5 pound savings per side). The factory nose was also ditched for carbon fiber one that is 26 pounds lighter. And finally, an Optic Armor rear window was glued in for a 15-pound reduction. Each of those moves should earned Pure Evil a 143 pounds weight loss; Washington didn’t compare the new and lighter bumper support, lightweight dashboard, or the passenger seat removal.

As for the drivetrain, the G-Force G101A was pulled out for its usual off-season freshening and in its place is a “borrowed” G-Force G5R. It is a five-speed box and is the clutchless version since the rules don’t prohibit the number of forward gears nor the style transmission. The Black Magic Long-style clutch is being carried over and Cale and Tinzy Aronson of Black Magic Clutches will be on-site helping with the clutch tune-up.

PE-2 produced a stellar 744 rear-wheel horsepower on JPC Racing’s chassis dyno, a 104-horsepower gain over last year’s combination. It is the most powerful Coyote-based combination, sans power adders.

Washington isn’t touching the bullet under the hood, which is a RGR/JPC Racing Coyote-based badass that is 339ci. A factory Coyote block features a set of aftermarket sleeves pressed in it, replacing the GT350 block that Pure Evil used in 2018. A new set of GT350 cylinder heads were ported by Rich Groh Racing and upgrade with a set of PAC valvesprings to help control the custom COMP camshafts. JPC Racing’s Eric Holliday will handle crew chief duties, including the tune-up in the AEM Infinity engine management system.

Just how fast can Washington go by dropping from the NMRA-legal 2,675 pounds to roughly 2,500 and adding the trick G-Force five-speed? Our estimates put Pure Evil somewhere in the 8.50s at speeds approaching 160 mph. What do you think?
