I'm going to have a civic SI tranny on my car soon with a 9lb flywheel and stage 2 clutch. Assuming i'm not an idiot and can shift well, what do you guys think I should be running the quartermile in? The only mods to the engine thus far are a shortram intake and a powersteering underdrive pulley. It is a LS motor btw. in good working order.

noone's gonna really know until you actually run it, im guessing mid 15's

Well with the shortram you might be pickin up 5 WHP or so, the underdrive pulleys are worthless so they don't count. I'd say deep 15's....
