Engine problems rob Gidley, Doran of top-5 at Rolex 24

Posted on

After leading the race, and with a top-5 finish in sight after 18 hours of almost trouble-free racing in the 47th Annual Rolex 24, the #77 Doran Racing / McDonald’s Doran-Dallara Ford succumbed to the same engine ‘gremlins’ that felled six of the seven Ford-powered Daytona Prototypes in the 49-car starting field.  The problem in each case was ultimately traced to the failure of a crankshaft position sensor stator wheel in each of the 500 horsepower Ford V-8 engines.
