Mark Shead had a .68 5th in his 550bhp RS500 a few years back even with that Power it could not pull it, changing into 5th would completely stop accleration, put it this way my own car could not pull a .42. There is something wrong with the info given how could you change from 4th to 5th the revs are almost the same.

my car would be trying to pull 220 mph at 4500 rpm in 6th on that gearbox not even rod tarry could pull in 6th with that box so what use is it and 4th and 5th are not much different
youd need a 5000 hp dragster to use 6th gear
