This is a head scratcher for me. I've seen quite a few 17 ZL1 time slips now and they typically have a fairly high trap speed for their ET. Now drag racing 101 says the 60ft is key for ET and it's fairly obvious this cars 60ft issues are killing that aspect. On the other hand higher HP normally means higher trap speeds and some wheel spin can also increase trap speed. All that being said I still have a hard time figuring some things looking at the time slips and particularly this one.
I looked at a time slip I have where I ran a 10.74 and here are the numbers side by side.
660'.....1.749
1.616
330'
4.854
4.526 (.328 delta)
1/8
7.346
..6.928 (.418 delta)
Mph
.97.74
.101.58 (3.84 mph delta)
1k........9.454
Track does not record
1/4....11.227 @130.42
..10.740@128.46 (.487 delta and 1.96 delta in mph for 5.8 mph gain)
From the 1/8 to the 1/4 the ZL1 makes up 6mph? Is there a strong tail wind? The HP numbers and the results of now many roll races seem to indicate the Hellcat pulls on the Zl1 at the top end. Here we see, despite the nearly half second difference in ET that seems to be refuted? It seems illogical and I'm just trying to figure it out. The difference in 60fts is there but not a 1/2 seconds worth in overall ET difference. Is there some other factor I'm not considering? The time slips are real so what accounts for this? Anybody have an idea?
Pure academic curiosity and late night boredom demand an answer.

Perhaps it's the 10 speed keeping the engine in the sweet spot
