New batch of UD pulleys

lets fill this list, i am really looking forward to getting mine :rock:
 
Hey buddy. This is the first I'm hearing of this. If these are not "piggy back" pulleys and they are standalone pieces I would like a set. Please get me in the loop here... Thank you sir.

Eh, never mind on that one. A two piece would work better for me since I see an ATI damper in my future. Thanks guys. Good luck.

Mine are a one piece design but won't accept the damper.
Appreciate your interest :rock:

What do you gain from doing this pulley mod? I dont know a whole lot about underdrive pulley kits.

I have it on my truck, what it does is free up HP by making the accessories on the engine spin slower, therefore taking less power to run them. I definitely recommend it, because as far as these trucks go in HP per $, you will not find a cheaper mod. :D Not to mention it weighs less than the stock pulley and any time you can reduce rotating mass it's a win.
 
Exactly^^^ and in the case of my pulleys,taking over 1 lb on the crank snout, again freeing up power. I have a stock truck that gained 2/10th with pulley swap only. :rock:
 
I would want to be added to the list, but I gotta lotta other stuff I gotta do first.
 
For the most part I like mine so far but at idle with my HIDs on (fogs and low beams) my battery voltage drops. I also have 2 amps and a 7" screen in the dash but volts don't drop unless the HIDs are on, so just a heads up to people with HIDs, you could see battery volts drop at idle. Otherwise I don't have any issues. I may see though if Roe can raise my idle on my tune a couple hundred RPMs to help out the alternator.

If your idle is 750-800 then leave that be. Check your battery itself as it could have a bad cell or not be correct size. Needs to be at least a 700 CA battery and bigger with your HIDs and stereo system. More like a 1000 CA battery. Basically my pulley would show a problem with charging system/ earlier due to it spinning slower. If your battery has sat a long time or just not enough Amps, swap it and report back sir please :)
 
Running a Optima yellow top, so more than capable. That said, it sat out of the truck in my garage while I was deployed but my dad put it back in for me and it fired right up without a jump, so idk

Optima has gone bad over the years. They started out with a great battery, earned a name, then sold out and make not so great batteries.
Is it at least 700amps?
