135mph in my civic with a good bit to go
145mph in the 300zx with a dodgy clutch and not trying
4.5k rpm in 5th in my deathtrap of a sierra, no idea what speed as i have no speedo..

i'm more of an acceleration guy, usually up to about 90mph or summit.. top speeds don't do much for me, especially as you don't get a chance to use it that often!
