6R80 conversion in 2003 Mach1

[95opal]

Well end of year track visit and it was all worth it (doing the 6R80 swap)!
My previous best time with the T56 magnum was a 6.63 @ 112 mph 1/8th and 10.18 @ 140 mph in 1/4.
Yesterday I ran my personal bests so far with the 6R80.
6.28 @ 114mph in 1/8th and 9.87 @ 125mph in 1/4.
I shredded my supercharger belt at 1000 feet and essentially coasted the reason for the low mph!
I am super stoked! Car is an animal on the street so I knew it was going to throw some good numbers at the track!

Working on videos now, but 1st pass I launched in 1st and blew the tires off.
2nd pass I launched in 2nd and it skated around a little but was a pretty solid run.

Now with video.
After watching it, I determined that my boost pressure was moving around a lot between 15# and 22# on first pass.
On the 2nd pass it was more steady around 20#.
The air/fuel is fat at 10.0 to 10.4 going down the track so I could lean it out some there.
It also had some tire shake in both passes and I attribute that to the low pressure in the slicks.
