syp's sho runs 13's right? Maybe he'll post up some info for you.
syP's SHO probably ran absolute bottom 14's. He raced my bone stock Cobalt SS a few times, and it was very close each time up to about 100, he would usually creep on me right at the very top. The Cobalt's are known to be lower 14 second cars.
His SHO also was a 3.2 swap (Manual transmission, Automatic motor, Manual cams, "The best of both worlds"), with essentially Full Bolt-Ons: Big Bore Butterflys, Y-pipe, extruded/honed runners, CAI, Exhaust, the aforementioned Manual cams. I don't think he had underdrive pullies... that'd be about it though.
As already mentioned though, this is NOT the vehicle you want to be in for drag racing.
Question #1: Is it Manual or Automatic?
Question answer for Auto: Sell it, the transmission will explode.
Question answer for Manual: Weld the Diff pin so the transmission doesn't explode.
Question #2: What is your budget?
Question answer for $1000-3000: Big Bore Butterfly valves for the intake manifold, Extruded/Honed intake runners, Catless high-flow Y-pipe, and spray the bejesus out of it and enjoy.
Question answer for $5000+: Home made turbo kit
Regardless of either answer, expect to drop $500 on maintenance items before you do anything else. You need to perform the full 60K service on the car to get the most out of it, hands down. If you do not know what this is, Google it, or sign up for
