I need guidance

set pulley ratio to give about 4000 rpm on the alternator,  and pull the rpm down to get a good load at that rpm.  Going over 195 degrees on the thermostat may require a pressurized cooling system!   

If your voltage dropped out with rpm you are probably spinning the alternator too slowly.

It's an open system right now, right now my exhaust gas temp is around 200 degrees (measured with an infrared thermometer at the exhaust flange) I'd rather be seeing 250 a diesel has got to run hot to burn clean.

I wound not trust a temp reading from a IR thermometer, i suspect it is actually higher. contact thermometers offer a much more accurate reading. or better a temp sensor in the exhaust stream near the head.

Oh I'm sure the actual EGT is higher than the IR on the outside of the manifold flange, after running since about 2 PM yesterday it seems to be a pretty good match right now, I like the slower rpms too, less overall noise and vibration.

I have a 17 foot home built wind turbine which works great when the wind blows,

We would be very keen to learn more about your DIY 17 foot wind turbine. You could do a write up hopefully with pictures here.  http://www.microcogen.info/index.php?board=17.0

I am trying my best to build an ambitiously sized DIY wind turbine as well. Mine is a 4 blade VAWT. I have been at mine for the past five years in a row now full attention.  I have realistic expectations of having it generating power next summer.

Well, here is a picture of the first flight, it's on a short test tower, this machine is basically an axial flux alternator, modeled after the alternators built by the folks over on otherpower.com, it cuts in at about 8 mph and I've seen 2.5kw out of it in 30mph winds, this is a direct drive machine, I am presently building a geared machine that should blow this one out of the water.
The first link is the direct drive machine, the second is the geared machine.

Very nice job on the wind turbine and gear box.  I have a 12.5" radial flux 2.5kw wind turbine (sad to say not home built),  it makes its rated power at 19mph and I have seen peaks of 3.7kw in high winds.  Max rpm for my machine is 350rpm.
