IMHO, that engine would be wasted with an ST head, it needs a single bearing bell housing mount unit, also turning down the governor will also derate the Kw output and possibly cause it to run in an extremely inefficient spot in it's power band. Too bad it's not 1800 rpms.

I am so very sorry, you are completely correct. I do apologize.

I have an F3L 2011 3000 rpm sitting on the floor, it's basically the same
engine you have. 30kw.

Have not fired it up but bought it as running engine. The core for an engine
like this one will bring $1,000 and a good used one $2,000 (if you have to
go out and buy one) this precludes junk yard bargains. Your's like mine
would have to have some serious rpm reduction to be used with an ST Head.

Very true about core prices but not paying that much around here. Yet I buy everyone I can get my hands on here in dallas. If they have good blockes, no cracks or breaks and good heads I buy them. Working or not working dont matter pay $50 to $100 each. They are all work horses, even the tier-2 and tier-3's. Parts aren't to bad to get around here but they are higher priced. Reduction of RPM's?? Why not just turn down the govenor? It will drop your rpm's.

If people stop living in the Tornado Alley areas most of the central united states would be without people.

QuoteFabricator: It wouldn't be cheap, but all you need to do is pour reinforced concrete walls and roof about 12 inches thick, then push up a berm around the walls, say a 30 degree angle then pour 12 inches of concrete on that all tied into the roof and walls with rebar.
All you are doing is building a reinforced hollow concrete hill, tornados don't level hills they go over em, any debris hitting those sloped walls would be deflected up, same principal as the armor on a tank, sloped surfaces for deflection, a house built like this would laugh at an F5 or anything else

I see what your saying, but I wouldnt want to put my grandkids in one that hasnt been tested. Besides it wouldnt be very cost effective your way. Think I'll stay with the underground concrete room, cheap enough and super safe, good enough for me.

Fabricator,
That would be a structure I would love to see the blue prints for. I have never seen an F3 or F4 that left any free standing concrete structures in any condition but rubble.

The wind force being so strong it takes the bark off the trees, then uproots the trees and twists them around cars and trucks. It takes steel pipe that is concreted into the ground, bending and twisting it as if it was nothing. An they say, thats only the straight line winds before the tornado that does that. 

So if you can build a structure to withstand an F5 Tornado, that a family could use and be safe from harm in then I would be very interested in seeing your structure drawing. So far no one else has been able to build one to withstand an F3 or F4 direct hit.

I have sons in Missouri and we are building them both new tornado shelters this summer, so I would be very interested in how you would do it. 

Hi All,
I am in Texas and the last storm spawned 16 confirmed tornadoes here. One went directly over my husband's shop; he stood in the yard and watched it. It touched down less than a mile from the shop damaging a nursing home where there were only two minor injuries reported. The tornado that hit Lancaster Texas was horrible, only about 10 miles from our home. It was total destruction in that area,  as well as the one that hit Arlington Texas. We were very fortunate only 1 mile from my home one past through with minimal damage mostly roofs damaged was all. The clean up in Lancaster and Arlington has been hard for the first responders but the outpouring of help has been heartwarming. Donations of food to clothing to footware for those in need were collected. We could not have made it this far without our first responders, we appreciate all they do.

As for the concrete walls in a free standing shelter, I don't know that much about the safety of that. The tornadoes that hit here destroyed Tilt Wall buildings leaving nothing but rubble. Smaller concrete outer buildings didn't fare much better with a direct hit from a tornado. The only safe structure in my opinion is under ground, a concrete room with a sealed concrete tops. Having lived in Texas most of my life and then in Missouri I have seen my fair share of tornadoes and the destruction they leave behind. And the only structures that have proved the safest have all been under ground. If you're going to build a concrete structure for storms, why not go the extra step and put it under ground? This is just my opinion.
