The guys at Billet Technology are making a run of overdrive alternator pullies for us. These will help with your battery voltage at idle if you have a ton of electronics, low idle from a big cam, or an underdrive crank pulley.

These will be $29.99 + shipping.

Scott...how soon will these be available? The guys that try out that PPP underdrive damper pulley might be interested in this.

The pulley needs to be smaller so the alternator spins faster. The smaller the pulley the faster it will spin the bigger the pulley the slower it will spin.

No,, I think Jerry wants a bigger alt pulley. He has the Overdrive damper pulley for the blower.

I gotcha Denny. I can get those made too, will check on price.

This first run of pullies are smaller ones that speed up the alternator, just like that guy was making in his shop before he sold his hemi truck.

I will check on Monday but I think they started machining them on Friday so we should have them very soon.

There will be 20 units in the first run.

what kinda gains we lookin at with these?
Performance wise none by itself. It would allow you to use an underdrive pulley though and maintain your charging system for those with accessories.

That is a great price for these. I paid more than that for the one I have and I bet it will not be as nice as these.

5 minute swap.You just need a pair of channel locks or similar with and something to put on the pulley so you don't ruin it , and a thin wall socket .
