Generac engines

Has anyone had any experience with Generac engines? I always assumed (at least on the generators I have seen at Lowe's etc.) that the engines were the chinese honda copy engines, but according to their website their engines and generators are manufactured in Wisconsin.

I also saw that they now have a big v-twin (33 hp) and I am looking for another engine for one of my machines. Don't need one that big really, but if they are made in the U.S. I may try one.
 
The engines on the GP series up to 5500 watt are Loncin engines made in China. The larger GPs (7000 - 8000 watt), and the better series generators have the Generac GN190, 220, and 410 engines. They are made in America, as well as the GN990 twin that you mentioned. Dixie Chopper uses Generac engines.
 
I got one 13 hp for my back up pump. Just to see i have been using it for about 4 months and it`s been good. I have friends that have them and they tell me they have had good luck with them.
I paid 350.00 + 79.00 for the 2 yr Extended protection. if it brakes within 2 yrs 3 months i can take it back and get a new one.

Russ J, they seem to never die in the dixie's, but it could be due to the fact that dixie chopper follows the guide lines from generac.

Seller on ebay makes these notes:(cut and paste)

Lets compare Apples to Apples​
Kohler lists their CH1000 engine at 40hp Based on the Society of Automotive Engineers (SAE) J1940 Standard which is done with the Air Cleaner & Muffler Removed​
Actual DYNO testing with the muffler & air cleaner installed on a 40hp Kohler produced 33.1hp at the Generac Test Laboratory​
This Generac engine will produce the same to slightly more horsepower than the Kohler engine under the same test conditions​
Even more important is engine torque​
The Kohler Engine produced 61+LB FT of torque​
The Generac engine produced 63+lb ft of torque​
Generac 40hp (Per SAE J1940) max engine

GENERAC 40hp Maximum 33hp recommended Horizontal Shaft Engine Has a Whopping 64ftlbs of torque@2400rpm.
 
Nigel, it's like that across the board. A popular factor for figuring needed horsepower is (gpm X psi) / 1100. That is absolute maximum output under ideal conditions and full governor travel (wide open throttle). A much more realistic expectation, and contributor to longer engine life is [(gpm X psi) / 1450] X 1.5.
 
Russ I remember discussing this formula with you in another thread. Thanks again.....Thats why i made the comment about John T... 34 HP/TSF2021 cold water purchase. "Why sprint when you can jog."

Spoke to a pw company that have over 5000 hours on an air cooled Kohler
