time estimation...

i know my 97 gtp (2-door) runs about a 14.9 bone stock (only has 70k on it) maybe a 15 flat depending... i've got a 3.4 puelly and intake on the way and i was just wondering if anybody knows times with these 2 mods... i'm really just curious, i was thinkin it would be mid to low 14's with the added hp (based on minimal gain, 25 from pulley and 10 from intake, putting the car at 275) anyways, a track time would be great to know sinse there is no track around here to go to.
