Top Speed on an 87-93 GT

I have a 1988 Mustang GT 5.0 AOD and i've never tried it but i was wondering how fast these go on top end? Yesterday I had my gps and had it to 121MPH and it was still pulling pretty good and let off do to traffic. Also how about a 1999-2004 on top end also?

Thanks
John

The 87-93 5.0's have been know to run about 137.....BUT....some have run as fast as 148 mph...

The 99+ GT's can run anywhere from 137-150 mph BUT it get's there alot quicker than the 5.0.....making it much faster...

I hope that helps ya.

my '94 GT has been up to 137 and I still had power for more but my cowl was threatening to fly off and I decided that that was quick enough for me...
btw I have 3.27s and a 5 speed

my top speed was about 145 or 150 with stock gears, not sure now. i now wind it out way beyond the 140 speedometer but my speedometer is off because of the gears.

my 85 back when it was just a 3.73, headers/hpipe/mufflers, pulleys and crap like that i had it 5500rpm in 5th, dont know how fast i was goin due to an 85mph speedo but im sure theirs a mathematical equation to figure it out.
