The only reason I rev it to 4,000+ between shifts is the rpm travel between shifts...2nd to 3rd is almost a 2,000 rpm split..if I was to rev it to 4,000 in 2nd then shift to 3rd my rpms would start just around 2,000 rpm....3rd to 4th is worse, But hey...these weren't made for speed. lol...which I am going to change to a richmond 6 speed...5 direct gears and a 6th gear overdrive. Spendy, but worth it.
