Check out my sig for my times. These times are on street tires prior to any mods. I think with your setup, you could get mid 14's with TPI. What are you running now?

Sorry about that. Let's try this again.

if i would have done gears or slicks i would have hit 13's
check my sig.
the times don't reflect the heads, cam, or AFPR.
(if you aren't seeing sigs make sure its turned on in your user cp profile deally)
now that i ported my intake more and ported my heads i should be in the 13's
