Though slightly larger in displacement than the 255ci normally aspirated configuration used at Indy (subsequent turbo bullets were around 159 ci), Ken figures he's safe with a 9,200-rpm "chip" (race engines routinely tipped 11,000). How'd you like to mess with those headers? The reverse hood scoop vents considerable heat. As boost ascends, timing retards and fuel pressure go up proportionately. View Related Article
