beating a dead horse.. but
i have more questions...
anyone running underdrive pullies on their 4.0sohc?
how has it affected your charging system?
any change in temps?
is throttle response improved?
does anyone have a side by side comparison of side?
would there be more to gain from a tune?
and have you noticed any squeaking or slipping of belts?
are their color options(i would be wanting a red if avalible)

this doesnt pertain to the 4.0L.. but If it's anything like the results that they gave my 3.0L i'd get em..not a crap load of added power, but noticable in throttle response and the engine just revved quicker(the 4.0L SOHC outta like that since it's a revvy motor). If you get the alt pulley you shouldnt get any charging issues

I've been runnning a crank UD on my 06 FX4 for almost a yr now. (daily driven 20k a year)
I'm a big fan of underdrives. They reduce the amount of torque consumed and for the most part a driver who pays attention to temps and such will never have a problem.
Ranger specific experience:
I've pushed it quite hard. This last summer I sat and idled w/ac on in 90F temps for about 35-40 minutes before it started to overheat. (I have an e-fan) Mind you, during that time I did'nt move but about 100ft at most. Sat dead still the whole time. Also, I towed my 3500lb boat out on the interstate. It was running cool enough (with temps in upper 80s and AC cranked) that the e-fan did not come on while out there.
As far as charging.. here is what I measured with **everything electrical** running and at idle.
btw, Here is a tool I made to hold the crank still while removing the pulley. (heavy wall pipe and a lawn mower blade)

i cant see pictures you posted. but thanks for your personal non bs experience! i hardly sit in one place for a time and done use my a/c but maybe 15mins at a time or when its a hot day and my truck has been heating up in the sun and its like an oven when i open the door.
i will most likely get all 3 pullies so the water pump is still pumping out the same amount. and i will need the alt to be working its best

I had an underdrive pully for my 2.3 and it was a major diffrence. Better throttle responce and mileage with no charging issues. I have a race crank pully for my Mustang and have no cooling or charge issues. But I could tell i was at the limit of the alt with everything on and at a stop at idle. Changed the alt to a 130 and added more electrical loads but have no problems.
