Re: Underdrive and Alternator Pulleys? i think its worth the money IMO.
Your power level may be a little weaker after the install for electrical. If you are doing a cam install, its a great hp to bolt on. usually 5-10rwhp increase.

Re: Underdrive and Alternator Pulleys? really good mod....
the underdrive on the crank will get you a good 5-10rwhp, quicker spin up, and slowing the power steering pump down keeps the fluid cooler and makes the pump last longer...
the overdrive on the alternator keeps it at the factory speed so you don't have any charging problems (don't loose any hp by doing this)...
most of the hp gain comes from slowing the water pump, power steering pump, and AC compressor.....the alternator is easy to spin....
