Using a modified SSHS a 963mb pressure should be nearly equal to a 112 mph surface wind, using the pressure-wind relationship.
So there is a strong disparity between what Ike's present winds are and what they could be.

Easy formula for the surface wind/ pressure relationship is 1000mb - current pressure = N.
N+75 equals the maximum possible surface wind speed in mph. This formula is not set in stone as Katrina, Rita and Wilma all exceeded the pressure/ wind relationship by quite a bit.
