Looking at the timeslips that were posted on the screen the only bully dog run that was bs was the 7.9xxx, as it had a .3xx 60' and not even topfuel goes that quick in 60'.
The other two runs that were 8's were a low 1.4x and a high 1.3x, both very believable runs. I didn't write down the increments at the time, but I did pause it and look them down, nothing stuck out as an anomaly other then the 7 second pass.
Ashley Black's trucks last exhibition run (the 9.0x) had similar short numbers 60' and 330', but was way down on the mph 150 vs 160. If they had the extra power that run they would have run a very similar 8.7x time.
So yes Bullydog smoked the lights on the one pass (the 7sec one), and it always shows in an unreal 60' in this case a .3xx, same as Armor's 9.17 run a year ago in mission with the .9xx 60'. If the truck runs the typical 60' and all the other increments make sense to that, it is hard to factually argue that.
Where they have their wastegate pointed is another debate all together.
