Haha, I live in Pittsburgh and the strip is 1100ft above sea level so my times are a little slower due to slightly below average DAs. I'll post slips but they're at home, if I can remember my times were:

Run 1: 12.5 112 (Brother-in-Law at about 250lbs was in the car eating sheetz and I ran as soon as I got there after a 1 hour drive)
Run 2: 12.3 114
Run 3: 12.18@115
Run 4: 12.17@115
Run 5: 12.18114
Run 6: 12.09@115
Run 7: 12.03@115
Run 8: 12.02@116
Run 9: 12.01@116
Run 10: 12.1@115 (Was wanting to break into 11s and spun on my launch)

I was running 18.5psi from 3k to 5.5k then tapering severely to about 12psi above 6k rpms, not one limp mode the entire time which was very surprising. The runs were done starting at about 7pm till almost 10pm.

I've been fbo with meth and e85 for about a year and have 70k miles on my car. I am running 18.5psi midrange tapering to 12 above 6k rpm.

Have you seen the thread about the transfer case in the xi section. One was torn apart by a reputable transmission shop and he said it was very solidly built. Having incorrect tire sizes will kill a transfer case faster than the launches on these cars.

Not bad thank you for posting buddy!!
I just dont believe that there is no one out there running rb on xi with meth!!

Some of those have to be fake. Number 4 is definitely fake, no one traps 96mph in the xi with a 1.7 launch and has a 7.8 1/8th time.

Does that mean you can't run staggered wheels on the xi or if you do you have to run the 225/40/18 front and 255/35/18 rear?

Means front and rear sizes have to be within 1% variance or thats big trouble.

I know some of the factory xis came with staggered wheels but I'm just running 235 square with great traction and very neutral steering but I understand that people like hte look of staggered.

I'm running 235/35/19 up front and 265/30/19 in the back. As long as the difference is within 1% you should be fine

No oil cooler, I didn't go over 250 on the oil temps.

[amclint]

going to the track tomorrow, meth kit is in but giving me issues, if I get it sorted then I will put nitrous in, just running out of time! Tnt is 4hrs so I will take a full bottle with me.

12.0 @ 117mph on vbox(1.85 60'), map 7 g5, e85, bms flash, dci is all, not sure what to expect with meth and n2o

Good time but you can do much better than a 1.85 60, you should be able to consistently do low 1.7x

1.85 is on the street and I wasn't launching hard, at full boil I was able to do a 1.56 60' which is the best any XI has ever done.

[pits200]

Wow 1.56 that's crazy, my best is 1.64 I think. I mean you must have great DAs at your track because if you ran a 12.0 with a 1.85 that would equate to about an. 11.4-11.5 with a 1.56 launch which is kind of hard to believe but if true that's awesome

What about 6sp manual is it better or worse for upgraded turbos and more power???
