I am in the middle of building my latest project, a PS 14/1 with a ST 20 KW generator head from Joel. The 14/1 comes from the factory with extra heavy flywheels and looks very well made. I also have a dual sized pulley from Mike. He specially made it for me and weighs about 120+ lbs for a massive stored energy potential at 1800 RPM. The small size is for 600 RPM and the larger size is for 850 RPM. This pulley is a work of art and has to been seen to believe, a very high quality unit.
This would provide about 4,500 watts @ 600 RPM continuous with a 4.44 x gen head vs. continuous rating with the small pulley and about 6,375 watts @ 850 RPM continuous with a 3.14 x gen head vs. continuous rating with the large pulley. They both have a momentary surge capability up to 20 KW.
This is an ongoing experiment, trying to have a tunable generator for both economy or power if needed. I’m going to try to run my home without my inverters and battery bank and opperate on the 600 RPM setting for maximum fuel economy and with a four and a half to one over sized generator head should start my well pump and other high surge devises with ease at the same time provide a smooth continuous AC output.
This unit is like a modern day Start O Matic ( I know not as good but close) but 4.5 KW and not 2.5 KW.
I have a spare turbo from a 5.9 Cummins that I might add to help keep the piston cool with 2-4 LBS. of boost and not increase the power by increasing fuel delivery. The turbo is too large to make useable power but is sized right so it can increase the operating life of the aluminum piston. Diesels engines function opposite of gas engines, the more air they get in per load, the cooler they run. I’m also not going over 4 PSI at full load as to over strain the internal components.
When finished I’ll post photos if you like.
