Hi Chris,

First, congratulations on your first flight and ma= king it around the pattern without incident ... well done.

 

Second, I have a radiator similar to yours; it is = 20x5.5x5.5 inches core dimension, with 1.5" in/out hose connections.&n= bsp; It is made by Ron Davis Racing - not Ed Klepis, but otherwise very sim= ilar.

My water coolant numbers (215-220F) are a bit bett= er than yours but not significantly, based on 80F and 85 mph clim= b airspeed; at the same time my oil temp is 175-180F.

I am still looking for further optimization of the= coolant system myself but chose to operationally-limit myself to <= 80F while building time on the airplane ... now have 30 hours.<= /p>

What was the OAT at time of flight? -  and wh= at was your airspeed during WOT climb?

Jeff
