Just checked out the LG motorsports website. They claim their power pulley underdrives at 35% (which would give it more underdrive than the ASP pulley). It appears to be a piggyback pulley. The package also comes w/ a proper sized belt and Redline synth power steering fluid. Is anyone running w/ this pulley? Comments?

Also... how hard is it to install one of these piggyback pulleys?

 

The stock pulley is also the harmonic balancer. You have to pull it off and put the small pulley on and then bolt the old pulley/harmonic balancer in front of it. You don't need the fluid that comes with the LG kit.
You can buy this on eBay for 50.00 or 65.00 with the belt.

It only adds a few hp in the higher revs and barely if at all charges the battery when idling.

 

I know I won't get much HP out of it (.7 according to WS6.COM). What appeals to me is the torque increase (5.0 according to WS6.COM). Again... anyone running w/ this LG motorsports pulley?

 

$129 is pretty high for an UD pulley. I bought an aluminum March pulley (used) for $50 here, it's a 25% UD. I dont know why they say you dont need a pulley puller to install it, my stock balancer/pulley wouldnt budge without one. It's pretty simple to install once you get the stock balancer off. I wouldnt spend $129 for a pulley, and you dont really need the synthetic ps fluid.
