"A Mustang cannot beat an LS1. Simply cannot happen. Please refer to this guide if you're a Mustang owner that thinks you may have beaten an LS1.
#1 The LS1 cannot be beaten.
#2 All Mustangs are stock.
#3 All LS1s run mid/high 12s bone stock from the factory.
#4 Even the 03 Cobra is a mid 13 car.
#5 The LS1 was not racing.
#6 The LS1 was parked.
#7 The LS1 was just playing with you.
#8 The LS1 was actually a V-6 with Z28 badges.
#9 The LS1 was actually an LT1, which can only be beaten by an LS1.
#10 The race does not count because it ended before 160mph.
#11 The race does not count because it did not start from a roll.
#12 The race does not count because the LS1's passenger was performing oral on the driver.
#13 The race does not count because the LS1 was not properly tuned.
#14 If you still feel your Mustang may have beaten an LS1, please see #1."
