140mph at 7500rpm in 5th according to previous owner /shrug he did several track days.
Me, never tried it as I drive it pretty slowly the majority of the time, I dont think ive been the wrong side of three figures since I bought it.
Im the one cruising down the motorway at 4000rpm in top gear doing 73mph (Bloody RA's :( )
I know someone with the WRX non RA (same age as mine) and his goes upto 155 with 90mph being a pleasing 3500rpm in 5th (or so im told).

Anyway 140 with my gearing I hope to change it one day.
