Well I ran 14.6 back in the day with a - cold air intake,stock pulley,2.5'' dp,p-log, polly uppers and a tune that consisted mainly of maf tune and transmission tuning. That was with a 2.1 60ft on street tires.



So quarter mile wise I would guess about the same. That pulley is more than likley hurting you. And depending on what kind of ''tune'' you have that could also be hurting you.
