Zate, you want it to sit at the HP peak, not the torque peak.

Also, for motorsport applications, there are a few driveability issues. Basically comes down to you're taking away one of the sensorary inputs for the driver. When you're driving a real track, you sort or program yourself to know that you should be in the bottom of 3rd gear through this turn, or you should downshift here...or whatever.

with a motor that always sounds the same, it's MUCH harder to know JUST how much to slow down going into turns.

This is what I learned this past year, while I was talking to one of the really fast A-mod autocross guys at Nationals. Their car for reference is 1000 lbs, 230hp, and has MASSIVE downforce.
