1/4 Mile Time Slip - Reasonable?
How's this look?
60ft - 2.223s
1/8 - 8.857s @ 84.8mph
1/4 - 13.513 @ 106.4mph
I shifted at 5300rpm, clutch on each shift, full tank of last year gas, spun a bit too much at the start I think. Do you figure I'll get it down to 13.1 if I squeeze it hard?
Winter is over... it's good to be back in the saddle.

Try launching with about 1/4-1/3 tank of fuel and leave the jack home.
Once you have the launch perfected, try varying the shift points for best ET.
What kind of rear tire, what inflation, what kind of burn-out, what staging (shallow or deep)????

street, but now i just use dr's for bracket racing.
haven't gone any faster, but i don't have to worry about spinning.
you can get the most out of your car with street tires and stock power, but it's a fine line between hooking and spinning.

PRACTICE, PRACTICE, PRACTICE and hope for good air
you'll also have to bring your rpm's up to at least 1500 and let the clutch out as fast as you can without spinning and flooring it at the same time. you don't want to slip the clutch, that will kill your et. experiment with launch rpm the higher the better. it's a fine line, but once you do it
all the way home. Mojo went 13.0 with his 95 when it was stock

My bone stock vert, with a 3.54 gear and a chip trapped at 105.xx. Consider that gears do not help trap speed, verts are heavier, and mine is a automatic, I know he could trap in the 106 range.
FWIW, under ideal conditions, traction, gearing, etc, 106mph will put you well into the 12's. But, when you start hooking hard, parts do break on these cars, at least that has been my experience.
on your numbers.

Come out to the corvette challenge this weekend, oh I see you're in texas, easy to talk from so far away. Don't lie, never have, never will, no reason to. When I braket race I usually dial 13.20-13.30, and my trap speeds are between 106-107. It was the perferct run on a perfect night. Don't know what the da was, wouldn't doubt it if it was negative. Englishtown is one of the fastest tracks in the country because of how close to sea level and the great air (cold, dense, dry). There are bone stock auto lt1's running 13.5 with much warmer weather then when I ran my best. All the modified ls1's with head, cam, exhaust are running 11's.
