George,

 

I have done climb testing from the 120 KIAS to 170 KIAS range in five knot increments and have yet to best much more than 1100'-1200'/ minute sustained. I am not talking about cooling issues here-- just power available versus power required. My fuel flows are in 42 gallon/ per hour range. I do not recall TIT from the test. Take these figures here with a large grain of salt as I am working strictly from memory. I will get back to the testing as soon as the weather improves here.

 

For those with cooling issues (as most of us seem to have) I have had a .75 x 1.5 inch hole cut in the forward right baffle in front of the number five cylinder to improve cooling to it. I have also tried to improve the number two cylinder (now the hottest cylinder) by standing off the oil cooler diverter a bit. I have the Lancair factory built baffling-- not the builder's built baffling you may have seen on other aircraft.

 

In cruise, on a standard day plus in the mid teens, running 75-100 LOP at 31.5" and 2600 RPM at 17.7 gph, I see CHTS in the 330 -350 range. I am always running LOP-- GO FAR.

 

Regards,

 

Jeff
