Stock internal ls1 back to track for testing
1st pass
60ft 1.5571
330ft 4.6953
1/8th 7.3064
mph 94.34
1/4 11.4595
mph 116.25
Details- around 80 degrees out, da was around 1800 or so, was only running 22 degrees of timing. 5500rpm launch
2nd pass
60ft 1.5193
330ft 4.6657
1/8th 7.2747
mph 94.48
1/4 11.4255
mph 116.16
Details- da=1857 80deg 49.7%hum 30.14 bpressure, finally saw I was only running 22 deg of timing on the data log, a/f was close to spot on at 12.9 so I didn't mess with it. 5500rpm launch
3rd pass
60ft 1.6286
330ft 4.7465
1/8th 7.3479
mph 93.15
1/4 11.5277
115.89
details- didn't check the da but it felt about the same. ran 28 deg timing. car spun hard off the line. tires were only at 10 psi cold but I didn't have no way to air them up for the run. 5500rpm launch
4th pass
60ft 1.5011
330ft 4.6039
1/8th 7.4500
mph 75.60
details- it was a lot cooler out around 55deg, put air in the tires 11psi cold, 6400rpm launch, lots of dew out as it was 11pm at night, about 100ft before 1/8th or so the car started to move around assuming it was the moisture on the track and let out. Left lane New best 60ft
5th pass
60ft nothing because the track equip did not pick it up for some reason
330ft 4.5905
1/8th 7.1670
mph 95.54
1/4 11.4180
mph 107.66
details- right lane run, ran almost right after the 4th pass, 6400rpm launch, got close to the 1/8th or after and the car started to move around again so I let out real quick and got back in it for about a second then let out and coasted through the 1/4. I thought I didn't stay in it too long past the 1/8th when i got in and out of the throttle but i may have been at the 1000ft when i was completely out of it. Looks like the 60ft may have been a bit better cause of what the 330ft reads.
Car weighs an estimated 3150 to 3200 raceweight. 100 percent mwc front and rear suspension with fab 9 4.11 26in et street bias ply on bogarts. Viking coil overs on all 4, strange drag brakes all 4, rpm faceplated t56 fbody gearing. monster level 3, ported fast 102, kooks 1-7/8, sd tune, vacuum pump, driver mod blah blah blah.
Didn't try to hit my shift point at 5700rpm all night, was messing with that clutch slipper device called the clutch tamer for the first 3 runs and was helping someone out with there car on some grudge races. Never got it to work cause I'm still learning how to use.

Short 1 second test hits in 2nd or 3rd gear can speed up the ClutchTamer's dialing in process, as eliminating wheelspin makes it easier to zero in on the "initial hit" setting. Since the goal is matching the clutch's initial hit to the engine's output, 2nd gear test hits from your torque peak make it possible to get close in a driveway/parking lot without doing much prep other than maybe sweeping.

Thanks guys, I'm anxious to see how much more it has in it. I may be able to squeeze a little more out of the tune. It had some older gas in it from September. Tune looked ok but it wants to go 12.4 afr to 13.1 in the same cell for some reason. I have it commanded at 12.9, I honestly thought that running 28 deg timing over 22 and the cooler air that night it would have went faster than a 7.16

Are the graphs from the 2nd run?
That quick little 800 rpm drop off the line tells me the clutch had too much initial hit. Even with too much wheelspeed, rpm still got pulled down to 3700.
I'm thinking add some air to the tires, back the clutch's initial hit off a turn or two (5 or 6 turns of delay), bump the launch to 6500 or so, and shift that faceplated T56 WOT.

I plan on adding some air to the tires here sooner or later when I get the clutchtamer adjusted correctly. Sadly the way I have the suspension setup the car will blow the tires off above 13psi. Its still stock cam so I'm not able to bump it to high. I don't wanna eat up the stock springs that are in it. 6500 is probably as high as I should go, honestly that's too high for the valvetrain that's in it.
I didn't even notice that I was lifting on the log till you mentioned it. I was lifting earlier in the year because I did not have a rev limiter to catch it on the no lift shifts. That was the reason for the original springs to get weak. I bought the true 2 step lingenfelter has out now and pulled the old lnc2000 off.
