I usually shift between 3-5k rpm while the engine is warm(under 3k when its cold). I sometime try to wring the engine out at redline but this baby gets up in speed wayy too fast. It's really hard to drive at the speed limit with this car.
However the other day i was in a rush and had to get a spot in the no 3 lane before it was too late, i gunned it from 2nd gear til 3rd and almost redlined it and the speeds was like 75mph or something it all happened so fast i got really excited/scared as to the gobs of power that this car has. Boy what an engine.
