Kyblack76 Posted June 1, 2017 Report Share Posted June 1, 2017 Yup,....4 singers here. Kenny drove me, and the fucking thing 1100 miles , one way to world finals. We shut 3 off via a switch driving. Only time all 4 are chugging is in the lanes. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
nocturnalrites101 Posted June 2, 2017 Author Report Share Posted June 2, 2017 seems to be the common thought is put switches on the exciter wire on the extra alts Link to comment Share on other sites More sharing options...
SterTheDer Posted June 5, 2017 Report Share Posted June 5, 2017 Some simple back of the envelope calculations: Let's assume 360 amp alternators, at 15v. 360amps * 4 Alternators = 1,440 amps. 1,440 amps * 15volts = 21,600w 22kw is roughly 30horsepower. So, being extremely generous here, if all four alternators were operating at full load, you should see 30-40horsepower load on your engine. For comparison, your A/C compressor might be putting a load of 10-20horsepower (Depending on the size) "1 ton cooling power =12k btu/hIf it is a two tone unit then it draws 24k btu/h of energy.1 ton=12k btu/h1 hp=2,544 btu/hrtherefore for a 2 ton unit it draws 12k/2544=9.4 HP3 ton unit 36k/2544=14 HPThere are also mechanical losses as well such as noise, heat& belt on top of that.I did not include the power drawn by the fan either."- Caspiam M, in a forum post located here: (https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1944982) So, if you are driving a small 4cyl engine, with A/C and 4 alts at full tilt, it might make it really sluggish to get up to speed, but with a truck/SUV large enough to mount quad alt's, you really shouldn't notice much if any decrease in performance.
