Re: Underdrive Pulleys (LS7)

Got mine from LGM, though many of the supporting vendors carry them. Usually right around the $300 mark.

Good luck. :thumbs:

ASP Underdrive Pulley Kit increases horsepower by reducing power required to drive external engine accessories.

Underdrives the alternator, power steering, water pump and air conditioner by approx. 25%.

Expect an increase of about 10-12 horsepower.

All pulleys are manufactured from billet steel or aluminum, exceeding all factory specifications.

Extends power steering pump life (very important on LS1 engines!).

A must for drag racers, autocrossers, road racers, and anyone who's engine sees high rpm use.

Re: Underdrive Pulleys (Cary)

yeah but if your underdriving your alternator by 25% wouldnt that eventually kill the alternator pretty quickly? i know lots of people (non vette owners) and when they did this is killed there alternator......but thanks for the input..i might just have to consider them
