Guy at work always brags about his BA 370Z, claims he would out run me, because his car isn't as heavy. From what I have read he's pushing about 330hp and they run around mid 13's. The Shelby GT is said to have 315hp with stock Ford Racing CAI and performance X-Pipe. I have ran a 13.3 at the track. He has more horsepower, but I'm not so sure he would outrun me as easy as he thinks… Should I wait until I install my headers & exhaust, or line em up now?! Thoughts??
