I have 2 T20001bd's, thanks to ztaebevets, and another forum member who's name escapes me at the moment, I plan to run with these beasts. I will post pics tomorrow. I would have taken pics today, but wife was on her way home from work, and this is our little secret!! I'm going to upgrade the Big 3 and get 2 PM D3100's. I was going to purchase a mechman 250 HO Alt today, but a rep from mechman suggested that I try just the PM's and the BIG 3 upgrade first. Considering my vehicle's electrical system charges about 100-120 amps at idle and 120-160 amps over 1000 rpm. The 250 amp alt has a less charging amperage rating at idle than my stock alt. What are you guy's thoughts?
