Since I haven't been able to make it to the track, I figured I'd get a little information out of one of my log files. I can run consistently just about anywhere and it will hook up and drive straight if I don't go nuts with the boost at the launch. I exported the data from HP Tuners into an excel file and was able to integrate velocity versus time to find distance traveled. I then solved for the variable t which put me at the 1/8 mile mark. I did another similar calculation for the 60' time. As you can see in the graph, there were no sudden jumps in speed indicating wheelspin which would void the results. Also assuming you all trust that I have entered the correct data in for tire and gear size 
...here are the results:
7.2 at 104mph in the 1/8 mile with a 2.073 60'. 0-60 in this run was 3.12s, leaving easy on 6psi with 16psi full boost. 4wd obviously, no meth, no nitrous. I haven't made any street pulls to the 1/4 mile yet, but I might try it out this weekend. I have launched on the street before at 12psi, but it was spinning em all at that point so I don't know how hard I can leave before the information becomes inaccurate. A little harder launch should put me in the 6s in the 1/8 or 10s in the 1/4. Probably pick up a little in trap speed as well. We'll see!

Last time I went to the track, I strapped my front end down, a little tighter on the right side to try and even out the front wheel spin. Pulled a 1.61 60' on that run leaving at about 5psi. Unfortunately I was bracket racing but had a buy (=free time trial), so I had 7 degrees of timing pulled out and 2 psi less boost so I didn't get kicked out. That was on 2 year old street tires. I think if you do something similar with the front, you'll be in the 10's easy. I ran an 11.10 that pass. My best of 10.90 had a shitty 1.84 60' so I bet I would've been around 10.5. Play with it, I think with meth and good fuel you can pull some mid 10's out of it on street tires without too much trouble.
