I don't know what kind of kit you have on the car, but if it's that rich I'd drop 2 fuel jets immediately and see what you get, or take a 1/2 lb of fuel pressure away (if it's a low psi setup, if it's a high pressure setup I'd change the jets)
Get some video from behind the car, that will help tell what the car is doing and will help alot.
Your et for the mph is pretty good, I'm running about 142.5+ mph and only seeing 9.5x so you're doing pretty well so far.
I want to see what the tires are doing on the hit too, if they're really wrinkling and whatnot you may find that if they are wrapping up alot that tubes could help you because they stiffen the sidewall up some.
Video, I need video to help more!

I mean someone standing behind the car with a camera. Just get someone to hold a camera and tape the run from behind the car on the starting line, and if possible a run with no changes from the side and get a good look at the tires and see what they're doing.
If you can get it done on a camera that can put it in slow motion, that would be perfect.
Mark a god sized white stripe on the tires too, so when the side view is shot we can see how much the car is spinning at the hit. a 2 inch wide stripe from the rim to the tread would be good.

o.k. I just watched the video now that I am home. Car is pulling to the left at launch from what it looks like. Do you have a piece of tape on teh center of the wheel, just to make sure that it's strait when you have it lined up? If not put one on it, it may help.
It's either that, or the tires aren't matched, car is rolling over, isn't square something.
If you can just get the car leaving strait you're gonna see it pick up. you're driving alot, alot more then I have to drive mine unless I get out of the groove.
Something to think about.

If the tires are good on the roll out measure and you're pulling to the left, take some pre-load out of the passenger side of the swaybar, start with a full turn and go 1/2 turns from there if it persists. If she's rolling over that's could be why the bar is rubbing the shocks.

Don't get too tied up in the 60 foot # because eventually you're gonna find that it's not the absolute end all deciding factor as to wether the car is working or not.
You want to be able to leave on all the power without blowing the tires off. If that means a 1.39 instead of a 1.35 trust me you are better off.
The wheelie's are cool and all but at the end of the day it doesn't win races, it's wasted energy lifting the car that should be moving it forward not upward. Best thing you can do is get the car moving forward as hard as possible, not upward.

Sorry Tommy! I got a video from behind the car on a 9.76@138 1.41 60ft pass. I slowed down the launch to 20%. Does that help?
