This page lists speeds for US and UK versions, which is perhaps a bit more of an upgrade than just the carbs: http://www.triumphspitfire.com/speed.html It doesn't list RPM, but that should be an easy calculation.
Mine has reached about 5400 in fifth (108 mph est.) before I chickened out. With a suitably crazy driver, it should do almost 120 mph. Very far from stock though... I would never encourage anyone to go that fast on a public road, especially in a spit. It really feels like it is floating over a hundred.
