New bests!! All in all a good day..
Off the trailer 25* timing:
60' = 1.54
1/8 = 6.60 @ 118.9
1/4 = 10.41 @ 125.55
No changes 2nd motor pass:
60' = 1.53
1/8 = 6.58 @ 105.92
1/4 = 10.38 @ 126.97
Opened the bottle with a 100hp hit off the foot brake 17* timing. I was given someone elses slip. Felt faster. Buddies told be it what it went. End of the night, my buddies that work at the track gave me a copy of the main printer print out but no 60'
1/8 = 6.25 @ 114.4
1/4 = 9.82 @ 132
Through the traps at 7,250 so I have a little more RPM
2nd bottle pass, trans brake launch. Lifted both fronts and unloaded the rear tires:
60' = 1.50
1/8 = 6.34 @ 112.7
1/4 = 9.94 @ 130.6
3rd bottle pass again trans brake lifting both tires and unloading
60' = 1.43
1/8 = 6.26 @ 113.0
1/4 = 9.88 @ 130.6
4th bottle pass. Swapped jets to the 175 hit, put a cold fresh bottle in and dropped to 13* timing. I was trying to get it up to temp and the track actually let me run 15min after closing to try and bring temp up. It was a bit low causing it to be fat enough to miss slightly down the full track. Again foot brake:
60' = 1.542
1/8 = 6.30 @ 114.1
1/4 = 9.97 @ 130.6
I think I need to tighten the shocks some for the bottle passes off the brake, clean up the AFR and add a bit of timing. I think it could go 9.6-9.7 with the 100hit and probably 9.4-9.5 with the 175.. Still have the 2nd stage. Need to go 8.9 before the turbos...

Looking more at things, I think there is a bit more in it. My normal 1/8 to 1/4 mph multiplier is right about 1.20 (105.92 @ 1/8 / 126.97 @ 1/4 = 1.198). With that a 114.46 1/8 would be 137.2 @ the 1/4.
The logs show rich through the RPM range (.73-.79 Lambda and I shoot for .80-.81 Lambda). This plus the very conservative timing table could account for the lack of top end.
