Who Would Have Thought Previous best: 11.73 1/4, 112+mph, 1.59 60' 100 shot, 22.5-23 degrees of timing, good 02#.
I posted a couple of questions on this forum over the last couple of weeks: 1) how to increase stock timing without computer mod? 2) and an O2 problem
Well I fixed the O2 - intake was a tad loose; No one could tell me how to increase my 22.5-23 degrees of timing.
In the process of fixing the intake a bolt was snapped off. Since I had to take the intake off to fix this problem, I decided to put on a new LS6 intake and a Thunderracing lid.
This was the best and the worst weekend of the year. Worst I only won one round on both days - rained out after the first round every day this weekend.
BEST Total Run:
60' - 1.52
1/8 - 7.295
MPH - 94.563
1000'-9.461
1/4 - 11.384
MPH - 118.245
On just a 100 shot; I did A-tap it. O2's .915-.935 (a little rich but I couldn't care, safe it better); but the timing had gone up to 25.5-26.5. The only change was the LS6 intake and lid. All my runs ranged from slowest of 118 (on the 11.384 run) to a high of 124.1; 60's were steady at 1.50-1.54. And by the way we had the worst air of the year steady at 4,800'+. A drop of .4 in the 1/4 and an increase of almost 11 mph.
This nitrous **** is really habit forming
. I basically went through 2 15-lb bottle this weekend 
Our track only runs every other weekend - maybe its time for a road trip south.

Re: Who Would Have Thought Nope.
Just went with 28x10.5x15. Shift right at 6100 1-2-3-4, cross the line at 6,000. I have the window switch set at 6,000. In fact on the 11.38 run the nitrous cut off just before the traps. Also, I do power shift. Shoot right out of the hole.
But you are right about the 26's. The engine is stock (stock heads and cam). I have tried the 26's and was running out of gear at about the 1000' mark. 5th is a bitch, so I picked up the 28's. So far so good. But if I go with the 150 shot I'll have the same problem and I don't think 30's will fit I'll cross that bridge when I get the up-graded in-tank fuel pump. Maybe a progressive controller is an answer.

Re: Who Would Have Thought Without going to 30", can I run 150 shot (assuming I get the fuel system for it) any other way? -- Remember stock engine, 6150 rev limiter ??? I would love to run 10's in good air this fall
