I only go above 4000 rpm when I get road rage. I gunned it once to 5500 rpm in 2nd when a gal in a T-bird was driving like a ditz. As I have been getting older (hopefully wiser), I have not been reving my engine above 3K too often.
the other day when getting on to the interstate I left my car in 3rd gear untill I got up to 65mph, and it was just over 3,000 rpm, or the same engine speed that I would have with a "normal" transmition, at that point started to feel bad for all those other people on the road, and even more so for the people who swap out VX tranny's for a DX or SI tranny, when all they have to do is drive in a lower gear for a simaler feel in proformance.
