Well, nhra doesn't use it to guage what you may run in the 1/4 by looking at the 1/8th mile time.
It's for safety .. and high 8s in the 1/8th is hardly enough acceleration to be deemed dangerous where a helmet may be needed because most people running high 8s are only trapping right around 80, but that same high 8 second car in the 1/8th can get dangerous at roughly 100mph in the 1/4.
