Were you on the brakes? For an M6 car, I would have expected to see 8mph more than that to hit 9s.
Granted, you crushed the first 60 feet... the trap still seemed low. Great pass.
I changed front tires 2-3 weeks prior and lost 3-4 mph off my top end. Still haven’t figured out where it went except for tire drag. I dyno’d the car even thinking it had Engine issue, nope 855 wheel like it puts down each and every time on the dyno +/- only 2-3 HP.
But yea, the run was all made in the first 300 ft of the track, car never left that hard ever. That was on a money race prepped track to which I only got one pass unfortunately as the track was crowded as hell. My car usually runs 10.6-10.8 with 1.5-1.6 60’s but I power shifted that pass which I usually don’t do as it’s hard on the tranny.
