+1I had no problems with shipment time and the color instructions and quality of the alternator and wire upgrade kits are quite nice.
That is about the extent of customer service I encountered. I never called them so I do not know, but their products are nice!
Shortly I'll be running about a 1000watt sound system, an electric fan, and HIDs. Will a 150amp alt be able to handle pretty much anything I can throw at it?
It should be good enough. 100 amps (idle) is good for up to 1400 watts of power. You might be a little bit in the hole if you have your electric fan, HVAC fan running, and all your lights on.So the PA Performance 200amp alt, rated at 100+ idle amps, should be good?
Also, I was wondering, would this new alternator take more power from the engine? Is it harder for it to spin the pulley?
No. You are only doubling the ABILITY of the motor (alternator) to produce electrical power. The alternator only puts out as much current as is being demanded at the time. If you have no accessories turned on, your alternator might only be putting out a few amps to run the computer and charge the battery. If you crank on all the lights, the HVAC fan, the stereo, and the electric cooling fan kicks on, your alternator might be putting out something like 150 amps. If this demand exceeds the capacity of the alternator (at the RPM it's running), then the extra current is drawn from the battery (discharge).Yes, thats what I figured, but I'd be more than doubling the electrical power coming from the motor.
Am I going to lose a noticable amount of speed?
Good bit of info, learned something new today. Thank youNo. You are only doubling the ABILITY of the motor (alternator) to produce electrical power.

You are going to rob power from the motor. The more current put out by the alternator, the more power it takes from the motor to produce it. It has nothing to do with which alternator you put on the car, it has to do with the fact that you are asking the engine to convert more of its power into electricity, rather than putting it to the rear wheels. You have chosen to put high electrical demand items on your vehicle, and the power to run them has to come from somewhere
Power (watts) = amps X voltage
A 200amp alternator that is putting out 100 amps is putting out 1.4 kilowatts. 1KW = 1.34 hp, so it's taking almost 2 hp (not including mechanical losses) to make that 100 amps.
If it's putting out its maximum 200 amps, it takes 3.8 hp. To account for mechanical loss, you should probably double that.
So you are losing 4 to 7 hp at the flywheel, and whatever that translates to at the rear wheels.
