My car is stupidly powerful, but limited by gearing, since it was never intended to go any higher than 180km/h on the stock ecu (fuel cut speed limiters suck). I don't have a stock ecu anymore, but I do have about twice as much power compared to stock.
I'll start:
about 240kmh / 150mph (gearing limited). 8000rpm, 5th gear. This was done in a controlled racetrack enviornment.
Never again. With a stripped interior and ultra sticky tires (with no attempts made to reduce road noise), the roar of the exhaust (3" straight through turbo back), and straight cut 5th gear, i couldn't hear for a few days :P
Now you.
