It really varies. I've seen them run 14's stock - but usually with horrible 60fts, but most likely with the mods you have now in the mid 13's on street tires. Getting good times really does depend on the launch in these things. I've seen lots of "supra" like 1/4 mi et's/mph (13.5 @111mph for example)with these trucks due to people getting a lot of power but either not knowing how launch it properly or not getting suspension work done.

When you add the 6lb pulley and get it tuned - you should easily get into the 12's with some practice.
