One of the reasons it took so long to get to this point was I wanted to go 
overkill on the cooling. As you pointed out, when I got started on this 
virtually everyone had cooling issues on the first flights. I built 4 
different oil cooler installations (and I dont mean minor changes - 4 
completely different setups) because I was afraid that what I had wouldnt 
work. At one point (probably been 5 years ago now) Chuck Dunlap visited my 
project. He told me I was over thinking things and I just needed to take 
what I had and fly it. I think that was oil cooler install #2.

Anyway, I'm hoping that I'll have the problem of too much cooling and I can 
start shrinking inlets. Time will tell.

And I did realize that I was OK with oil pan temp around 210 (OK, I realized 
it a little late). I backed off the throttle and then noticed the temp out 
of the cooler was around 185 so I knew I was OK. Heat of the moment I guess. 
In any case I decided for the remainder of the flight that not pushing it 
certainly wouldnt hurt anything.

Hopefully the next flight I wont feel quite so overloaded. Then can focus 
more attention on thinking things out.
