LOL, i love questions like this. It depends on how "HARDCORE!" you are, and what DD actually means to you. If DD means you'll drive your car in 98+ degree weather as well as in -20 degree weather with snow on the ground, then YES there is such a thing as too much power, because you're either going to have a lot of drama driving a 1000hp car in the snow (holy cow...lol) or youre going to spend a fortune trying to cool a 1000hp engine durring rush hour traffic jams in 100 degree weather. Also, it depends on how FAR your DD actually is. There was an article about a car that Rick Anderson built, with an all motor 400+hp 347, that clocked in with an 8200RPM redline. The engine was totally a race motor, not meant to have more than 10k or so miles put on it before it's rebuilt, but they joked about him using it as a daily driver since he only lives 1 mile from his work. So really, YOU would be a better answer for this question than any of us..lol
