Do you think UR would make a part that would not give you adequate charging for our cars. They would not be in business putting crap out there like that. The regulator brings the voltage down below 14.5 or so to keep the battery charged even with all accessories on. UR underdrive showed very little to no drop in voltage at all. This means unless you’re running a 500wt stereo system or something you will never know the difference. Just about 3 to 4 HP loss is all you will feel by running a OEM lighten pulley. These are like I said very slight underdrive, just enough to gain around 4 HP while keeping the voltage unchanged.
That's a wise tale about not getting enough voltage, at least with this company.
I have run Unorthodox UD pulleys for 2 years on another car and never had any issue.

Oh one other down side it will take about an extra 45 seconds to feel the full effects of the AC.
I also had to buy all new belts, $25.00 or so, no bigge though, almost time to replace anyhow.

I will try to do a picture by picture install if I remember.
