Well, so far my best time was a 14.94@ 92.13mph on stock tires, w/ an AEM CAI and cat back exhaust.....now that i have my header and new tires and rims I'm not sure what I'll run. Most ppl online are posting times of about 14.5s-14.7s with the same mods. So, I really have no idea what I'm running now, but I think it'll be closer to the 14.5-14.6 range, b/c I still haven't seen anyone online run a 14.XX in a Spec with just an Intake and exhaust. But, plain and simply put, we need a 1/4mi track close by so i can test these things more often 
, I think everyone is in agreement there. BTW, I'm also considering getting the new lightened crank pulley, which has been dynoed at 5-7 hp and tq at the wheels. (yeah thats nuts for a lightened pulley, but they say the stock one weighs a fuckload). So I see this as a decent mod.
I have the pulley your talkin about, seems like i have a bit more top end more throttle response, and a barely noticeable change in midrange. And what most people online are running 14.5 and 14.6? I go to
www.thevboard.com &
www.b15sentra.net i don't see it happening.
But there was someone on b15sentra that had a time slip for proof, that ran a 15.0 bone stock on 18's.
edit: i saw someone ran a 14.5 with intake header and exhaust.
