I raced a srt-4 last week, once from a stop and once from a roll. We both post on a local forum and i just finally got him to list his mods, so i waited for them before posting this.
Me: WRX, up/dp, sti catbak, mbc @14 psi, grounding kit, samco ic hoses, k&n air filter
Him: 04 SRT-4, Mopar Stage 2 Turbo Kit w/ Turbo Toys, Mopar 2.5" Cat-back exhaust, Mopar blow-off valve conversion plate, Mopar short throw shifter, AGP 3" CAI
from a stop I beat him to 60 by a car length, it was so cold i spun all the way through first.
from a 40-110 mph roll he started it so he got a little initial jump and continued to slowly pull and had about 4 cars on me when i shut down.
