Sounds like you had some fun. I would recommend some sticky tires,Mickey Thompsons drs. The guy with the shelby is not getting power to the ground,remember spinning is not winning.Finally made it to the track for some friday night fun.
first pass on nitto 555 street tires was a 12.83 with a 2.076 sixty foot time on a 91 tune at 4800 feet trap speed was 111.51 crushed and Evo!
second pass was a 12.9 with a 2.199 sixty trap speed was 114.45 on a JDM street tune that produces more low end power than the brenspeed tune that I used on the first tune. I spun the wheels too much out of the hole, got beat by another stang with giggle gas he ran a 12.62 on et streets.
third pass was the best. Ran my Brenspeed 93 tune launched with e brake at 2500 still spun the tires in 1st but ran a 12.733 with a 2.146 sixty, trap speed was 111.43 beat up on an older firebird that sounded nast but was not so fast.
Fourth run would have been good as I let the car cool down but then some guy in a Fairlane blew his motor and shut the track down for a while so I called it a night. Dude had a GT500 with the upgraded blower 625 hp, 3.73 gears and slicks and he was only running 12.8's or 13's?
