You don't build a car like that and *NOT* Try to eke out every bit of performance possible. Hell, some of the LeMans cars are using ELECTRIC power steering pumps with a motor that only turns the pump on while cornering. They say that when turning, drag does increase on the alternator that's about the same as having the PS Pump on, but there's no power steering drag on the engine when going straight. that saves what? half a horsepower?heh, you think you would notice the A/C is on in this car?it's no 4 banger that gets sucked of all it's performance when it's turned on. Besides ,can you imagine how hot it would get inside that car!?
