Well, for those of you who didn't make it to Baraboo, WI, you missed a lot of 
rain and cold.   But, seriously, it was a good fly-in.   The townfolk were 
really friendly and the maids and fast food service people all spoke english as

a first language.   And they say that Americans are to lazy to work.   There 
was a lot to do and a lot to see.   The country side was really pretty to fly 
over.

I really wanted to finish a cowling and take it.   We got really close.   
just ran out of time.   I spent 12-20 hours a day for a month trying to get all

the mods to my Tiger finished, plus work on other peoples planes (who wanted to

fly to Baraboo), plus teach 4 nights a week, plus finish a new cowling.   

I am quite happy with the Tiger.   With buried antennas, no steps, new 
Cylinders by LyCon (ported and polished), a complete Garmin stack (340 audio panel,

430, SL-60 GPS-Com, and 327 transponder), a JPI 800, digital Horizon tach, new

carpets, and trick side panels (you'd really need to see the side panels to 
appreciate them).   How fast is it?   Well, with a 65 in pitch prop, I can 
red-line the engine at 12,000 feet (though just barely) and it trues at over 145

knots.   There is still a lot to do.

CHTs:   On climbout, with an OAT of 90+, it's pretty hard to keep the CHT on 
#3 below 450.   The other cylinders run 20-30 degrees cooler.   I think this 
is pretty odd since #3 is the first one to cool when the power is removed, 
during descent.   On descent, #3 will show a cooling rate (as shown on the JPI)

that is noticably faster than the other cylinders.   Angle of attack is clearing

a big player in the cooling of #3.   

Throttled back to 130 knots (true), I can lean to about 7.5 to 8.3 gallons 
per hour.   

The next step is to investigate the pressure drop across the cylinders.
