But you're not going to see that (on that large of a pulley at least). Top swapped/ SSM90 kit cars (L36 blocks) have higher compression which means you can make more power on less boost, and that also magnifies the effects of other mods.
Damn, I thought yours was faster than that. I can hit a low 15 (almost into the 14s) as it is right now. Top swapped it's 13s or it'll feel like a waste of money.
