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.
