Default 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...

Nice pass, but it looks like it's losing alot of top end mph on both, motor and bottle. You should be trapping around 130ish on motor and 140ish on the bottle. Was the bottle psi low on all the passes? Is this an automatic car?

Auto and it is in a 63 c10 pick up. You can't compare 1/4 mile mph to anything that resembles something aerodynamic.

Thats moving. I had a 66 c10 and they are like driving a sheet of plywood through a wind tunnel. Zero aerodynamics

Gotcha. Didn't realize it made that much of a difference, sorta like Vette>Fbody.

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.
