... most of the V engines are around 90 lbs. the Briggs 'n Stratton Vanguard is evidently around 70lb. It's 125 lb. Not light at all. See http://www.commercialpower.com/displ...sp?docid=80498 Dan Yeah, something changed while I wasn't paying attention. Up through 28 or 29 horsepower was in that lower range of weights, IIRC. However, everything above 23 hp appears to now be part of their "big block" series, which is around 125 pounds for the air cooled version. There is also a liqued cooled version, which is even heavier. While the "rest of the story" is probably interesting, your point is well taken. BTW, the 23 hp Briggs engine (like the 20 hp Kohler engine) is still in the weight range that we remembered--although there does not appear to be any advantage in horsepower per pound. Peter |

My 38 peak hp Generac, stripped for flying and direct drive, weighs
about 79 pounds dry. It stays plenty cool installed as a free-air cooled pusher on my Thunder Gull. Valley Engineering is working on a version that they think will be about 70 pounds. |

Valley Engineering is working on a version that they think will be about 70 pounds. OK, so far so good. I did a quick web search and found a model GHT990, which is a 992cc V-Twin that seems to fit the description; with a max power of 38 hp and a recommended power of 32 hp. It is stated to weigh 119 pounds as delivered, which is about six pounds lighter than the 33 hp Briggs--for which I did not happen to notice graphs for peak and normal power--although they almost certainly exist. The question is: What did you have to remove to reduce the weight by 40 pounds? Peter |
