i have 3.73s and i redline 4th all the time. my speedo is off by 10 - 15 so i have no idea what my speed was. i know it was over 100..i'd guess maybe 130 or so.

i shouldnt say all the time. i usually shift at 2500 rpms hahaha but on some occasions i rip through the gears

see when i rip thru them, it cant keep up with the speed (speedo). it gets there really fast. im thinking right around a 1/4. i just dont see how it could be much over 100mph. i know mine couldnt be doing like 125 in a 1/4. but its got me curious.

yeah i know what you mean. and usually i am trying to stay focused on the road cause of how fast the car accelerates. i never really have time to look at the speedo. actually, i guess this speed could vary, depending on when you shifted in your other gears. for instance, if you dropped it in first, shifter at redline to 2nd, shifted at redline to 3rd and shift at redline to 4th..that would be top speed, or on the way to it. now if you shifted at 2500 in 1st 2nd and 3rd, then took it to redline at 4th, you wouldnt be going nearly as fast i dont think.

i'd think that redline in 4th is the same however fast you get there.. its all just gear ratios matching up -- its gonna be the same... it'll just take longer if you shift other gears at 2k rpm vs. shifting at 5500rpm
