Don Walsh Jr. • '12 Boss 302
When we told Don Walsh Jr. the morning of the competition that we needed his Boss to fill an opening in Dyno Wars, he was a little annoyed. "You could have told me earlier so I could have turned up the wick," he said jokingly. It was already sitting inside when we arrived, so we strapped it down first.
Walsh Motorsports is a full-service performance shop located in Wixom, Michigan, just a stone's throw from the now-defunct Wixom Assembly Plant, which built Lincolns since the '50s, and also built the Ford GT supercar. The only real performance mod done to Donny's Boss is the Hellion single-turbo kit. He beefed it up a bit with a Precision 72mm turbocharger, and added custom 20-inch wheels and lowering springs. Other than that, it's a stock Boss.
As he drives it every day, it laid down 600 rwhp and 560 lb-ft of torque at 8 pounds of boost. Walsh Motorsports lead tech, Justin Haddon, swapped the spring in the blow-off valve to make a little more boost. After reinstalling the BOV, the Boss put down 643 rwhp and 597 lb-ft of torque at 10.5 pounds of boost--not bad for a daily driver, and good enough to take the win.
