Kyblack76 Posted August 5, 2015 Report Share Posted August 5, 2015 Cool. Good to know. I ask because I don't know. Especially about diesel. That's rocket science for me. smokers rev LOW LOW LOW... they idle low, and peak low.... hell, at 85 on the free way, they rev at like 1900.... so, to see the full benifit of the higher peak alt,.. .......... well, that would be tough. Buy for your application.. not just "get the biggest you can fit"... The more higher end... you WILL suffer lower. You can NOT have both.......

rebar Posted August 5, 2015 Author Report Share Posted August 5, 2015 I need less than 1000 watts for my system and I'm shopping for dependability, more than huge amperage. So it looks like all those alternators are over kill. I idle about 800 rpm, but how that translates to belt speed is directly related crank shaft pulley diameter. The pulley diameter on my existing alternator is 2 9/16" with the belt on it. A little over 2 1/2" and I don't want to change diameter because my belt tension would change if I didn't change the belt out for a shorter one going to a smaller pulley. I cruise at 70 mph at 2000 rpm. Red line is 3000 rpm Quote Link to comment Share on other sites More sharing options...
