REFLECTOR: Investigation into Engine Failure

[Al Gietzen]

I do worry about my radiator capacity- I have a properly sized belly ram
scoop, but the radiator is single row (supposedly for racing) and although
it has good size, it is rather thin- about 1.5" but might just work fine.

Alex;

 

'Thin' is fine, if you can fit in adequate core volume.  With effective air
flow, it typically takes 2-2.5 cu. in. per hp.  With a pusher an auxiliary
fan is generally required for effective cooling on the ground.

 

BTW; I have the RWS (Tracy) EC2 on my 3-rotor rotary - which I believe is
basically the same unit he sells for a 6-cylinder.  I had one of the early
units, and had some headaches of being the beta tester.  It has evolved
quite a bit since, and has been operating fine. Mine has 125 hours on it
now.  

 

Best of luck,

 

Al
