4-Is it worth the money to get the complete pulley kit? Or just the Underdrive Crank pulley?
1 Yes. Both in "feel" and in power you put down. It's the second best mod I've done on my ranger.
2 Most impressive is tip in power at lower rpms.
3 A little but not too much.
4 I'm not sure. Do the other pullies speed up the accessories or do they further slow them?
I'd not slow them anymore. And if I lived in the south I'd want to speed the water pump up a bit.
tip 1: I've sped up my Park and Neutral idle speed to 800 rpms to help ac, cooling, and voltage performance. Last week I cruised woodward for 10hrs in mid 80s temps. I had the Drive idle set at 700 and the Neutral idle set at 900. Had absolutely ZERO problems. Hottest it got was 220F (e-fan set to come on at 215)
tip 2: Get a "84.5 belt" (not a 84.0 and not a 85.0 Trust me. I've got all three. The 84.5 is what you want)
